My honest review after the trial: Good tech, but the subscription model kills it for me.

devops_rookie_22 — Sun, 27 Sep 2026 22:50:45 +0000

So I tried Krisp for the whole trial period while studying for my cloud certs. The noise cancellation is honestly great. My home setup isn't quiet, and it totally removed my keyboard clacks and my neighbor's dog 😅 But as someone just breaking into DevOps, the subscription cost is a lot. I was hoping for a one-time purchase, even if it was higher. Now I'm back to tweaking PulseAudio configs, which is a pain but fits my budget. It's a shame because the tech itself is solid.

Results after a month: Did Krisp actually improve my call feedback scores?

data_analytics_rover — Sun, 27 Sep 2026 01:41:04 +0000

I've been evaluating Krisp for the past month within my analytics team, specifically to quantify its impact on a key operational metric: our average post-call feedback score. As we frequently present complex data findings to stakeholders in hybrid environments, audio clarity is a persistent concern. I hypothesized that reducing background noise would lead to fewer misunderstandings and higher feedback ratings. To test this, I designed a simple A/B test across 30 days of scheduled external calls: * **Group A (Control):** 15 team members continued with their standard setup (built-in mic, various environments). * **Group B (Test):** 15 team members used Krisp with the same hardware. * **Metric:** The 1-5 star rating from the automated post-call survey sent to all external participants. Here are the aggregated results for the test period: ```sql -- Simplified query of the results table SELECT group, COUNT(call_id) as total_calls, AVG(feedback_score) as avg_score, STDDEV(feedback_score) as score_stddev FROM call_feedback_fact WHERE test_month = '2024-04' GROUP BY 1; ``` | Group | Total Calls | Avg Score (1-5) | Std Dev | | :---- | :---------- | :--------------- | :------ | | A (Control) | 187 | 4.21 | 0.68 | | B (Krisp) | 192 | 4.45 | 0.52 | The Krisp group showed a **0.24 point increase** in the average feedback score. While this seems modest, the reduction in standard deviation (0.52 vs 0.68) is notable. It suggests feedback was more consistently positive, with fewer severe low scores. Subjectively, team members reported less repetition of questions and a perception of more professional delivery. However, a few caveats emerged: * The improvement cannot be solely attributed to Krisp. The act of being observed (Hawthorne effect) may have influenced behavior. * The test did not control for individual caller skill, which is a significant confounding variable. * We did not measure the impact of Krisp's voice isolation on the *caller's own* listening experience, only the recipient's feedback. From a data perspective, the observed improvement is statistically significant (p-value < 0.05) for our sample size, but the practical significance for a team is debatable. The consistency gain might be more valuable than the mean increase. For teams where call clarity is a major pain point, the ROI could be clear. For others, the benefit may fall within typical metric noise.

Top voice isolation tool for a hybrid remote team on Zoom and Teams

gracek — Sun, 27 Sep 2026 01:21:11 +0000

Let's be honest: the promise of "crystal clear audio" is the new "synergy." Every platform bakes in some noise suppression now, and yet, half my calls still feature someone's dog barking, a leaf blower symphony, or the dreaded keyboard clatter of a rep who thinks they're on mute. So when our sales org, now permanently hybrid, mandated a single voice isolation tool to standardize meeting hygiene across Zoom and Microsoft Teams, I was predictably skeptical. We trialed the usual suspects, and I fully expected the evaluation to be a wash. Instead, we landed on Krisp, and it's one of the few pieces of software that has actually, measurably, reduced collective misery. Here's the contrarian take: Krisp isn't just about suppressing noise. It's about eliminating the cognitive load of being a remote audio engineer. The value isn't in the AI model (though it's good)—it's in the implementation. * **It works at the device level, not the app level.** This is the critical detail everyone glosses over. You install it once, and it creates a virtual microphone and speaker. You then set *any* communication app (Zoom, Teams, Slack, Gong, whatever) to use "Krisp Microphone" and "Krisp Speaker." The isolation happens *before* the audio hits the app. This means: * No hunting for settings in each individual platform. The rep using Teams for an internal and Zoom for a customer demo has a consistent experience. * It works on apps that have terrible native suppression (looking at you, legacy web apps). * You can actually *hear* the difference when others use it, because it also filters noise *from their end* on your speaker output. * **The "Side Tone" feature is unsung hero territory.** Most isolation tools make you feel like you're talking into a void, which leads to people shouting. Krisp lets you hear a filtered version of your own voice in your headset, which preserves the natural feeling of speaking. This alone cut down on the "CAN YOU HEAR ME NOW?" interruptions by a noticeable margin. * **The real ROI is in reclaimed time and focus.** We're not measuring "clearer calls." We're measuring the elimination of the "Let's stop and figure out your audio" 3-minute sidebar at the start of every third meeting. We're measuring the lack of context loss when a siren passes by a rep's window during a key objection handling. Is it perfect? Of course not. It adds a very slight latency (negligible on a decent connection). The pricing model can feel a bit cheeky for large teams. And if your "noise" is a crying baby in the same room, no AI is saving you—that's a HR issue, not a tech one. But as a piece of sales enablement infrastructure? It's shockingly effective. It removes a variable. In a hybrid world where we control less of the environment, standardizing on this one layer of the stack has paid back more than most CRM add-ons I've been forced to implement. Anyone else using it at scale? Found the pitfalls after the honeymoon phase? 🤷

Windows 11 native noise suppression vs Krisp - anyone compared?

Emily K. — Sat, 26 Sep 2026 11:16:00 +0000

Hi everyone, I’m new here and still getting my bearings with all the martech tools. I’ve been using Krisp for a few months on my work laptop (Windows 11) to clean up calls, and I’ve been pretty happy with it. It’s been a lifesaver when the lawnmower goes by outside my home office. Recently, I noticed Windows 11 has its own built-in noise suppression feature in the sound settings. I’m curious, but a bit hesitant to just turn it on and potentially disrupt my setup. Has anyone done a direct comparison between the two? I’m especially wondering about a few specifics: * How do they handle sudden, sharp noises (like keyboard clicks or door slams)? * Is there any noticeable difference in voice clarity or latency during video conferences on platforms like Zoom or Teams? * Does using the native feature free up any system resources compared to running Krisp as an app? I’m trying to streamline my tech stack, so if the native option is just as good, that would be one less subscription. But I don’t want to sacrifice call quality for my client meetings. Any hands-on experiences or insights would be really appreciated. —em

ELI5: What's the difference between noise suppression and noise cancellation?

Elliot North — Sat, 26 Sep 2026 05:47:28 +0000

This is an excellent foundational question, as the conflation of these terms often leads to misconfigured audio pipelines and suboptimal results in production communication environments. While both aim to improve signal-to-noise ratio, their operational paradigms and technological implementations are distinct. At a high level, the difference can be framed as a matter of *input domain* and *processing methodology*: * **Noise Suppression** is a **digital, software-based post-processing** technique. It operates on the audio signal *after* it has been captured by your microphone. Think of it as a real-time filter applied to the audio stream. It uses algorithms (often spectral gating or machine learning models) to identify and attenuate frequencies statistically determined to be non-voice. Its primary input is the single audio stream from your mic. * **Noise Cancellation** (specifically Active Noise Cancellation or ANC) is a **hardware-based, analog-physical process**. It occurs *at the point of capture*, using specialized hardware (like headphones with outward-facing microphones) to generate an inverse sound wave to destructively interfere with ambient noise *before* it reaches your ear or your primary microphone. Its input is the environmental sound field itself. A practical analogy from data engineering: Noise Suppression is like applying a `WHERE` clause or a filter function to a logged dataset to remove unwanted entries. Noise Cancellation is like implementing a schema or ingress validation rule that prevents the noisy data from being written to the log in the first place. To visualize the pipeline divergence: ```plaintext Standard Setup with Software Noise Suppression: --> --> Analog/Digital Converter --> --> Setup with Hardware Noise Cancellation (ANC): + --> --> ``` **Key Implications:** * **Latency:** ANC introduces near-zero *processing* latency to the user's perception or the mic signal, as it's an analog circuit. Software suppression adds a minimal but non-zero buffer delay (typically 10-40ms) for analysis. * **Resource Utilization:** Software suppression consumes CPU/GPU cycles. ANC consumes battery power on the hardware device. * **Efficacy Profile:** ANC is generally superior for constant, low-frequency sounds (server fans, airplane hum). Advanced software suppression (often AI-based) excels at isolating voice from irregular, non-stationary noises (keyboard clicks, door slams, overlapping conversations). In optimal configurations, they are complementary layers in an audio pipeline: ANC hardware reduces the noise floor presented to the microphone, and the software suppression further cleans the residual and transient noises in the digital domain. Understanding this stack is crucial for diagnosing audio issues in remote collaboration or broadcast setups. -- elliot

Switched from Krisp to OBS noise gate for streaming - which is better?

Charlie99 — Tue, 25 Aug 2026 05:31:19 +0000

Hey everyone! I've been diving deep into my streaming setup recently, specifically the audio pipeline, and I made a switch that's sparked a lot of thought. For over a year, I relied on Krisp as my primary noise suppression filter, piping my microphone audio through it before it hit OBS. This week, I decided to experiment and replaced it entirely with OBS's built-in Noise Gate (and a touch of the Suppressor filter). Now I'm left wondering about the true trade-offs. My initial reasoning for the switch was two-fold: resource usage and transparency. Krisp, while fantastic, is another process running. OBS's filters feel more "in-line" with my scene workflow. Setting up the Noise Gate required some fine-tuning, but I got it to a place that feels responsive. Here's a snapshot of my current OBS filter chain for my mic: * **Noise Gate:** Closes at -40 dB, opens at -26 dB. Attack at 25ms, release at 150ms. * **Noise Suppression:** Using the RNNoise version, set to -20 dB. * **Compressor:** For leveling everything out afterwards. ```json // This isn't a literal config export, but my mental model of the signal flow: Source: USB Microphone -> Filter 1: Noise Gate (OBS) -> Filter 2: Noise Suppression (OBS-RNNoise) -> Filter 3: Compressor -> Destination: Stream / Recording ``` The results are... interesting. For consistent background noise like my AC unit, the OBS stack does a solid job. However, I've noticed Krisp was significantly better at handling sudden, unpredictable spikes—like a dog barking down the street or a keyboard clatter. The AI model seems to have a better understanding of what's "voice" versus "noise" in complex scenarios. On the flip side, I *feel* like my voice might sound a tiny bit more natural with the pure OBS method, but that could be placebo. So I'm really curious about the community's data on this! For those who have done A/B testing or have strong opinions: * **Performance:** Is Krisp's AI advantage worth the extra system load, especially when you're also running games, video encoding, etc.? * **Latency:** Have you measured any tangible audio delay differences between the two approaches? Krisp adds some processing time, but is it perceptible? * **Use Case Fit:** Does the "better" choice change if you're a music streamer vs. a just-chatting streamer vs. a competitive FPS streamer where every CPU cycle counts? * **Advanced Setups:** What about using Krisp *and* a hardware gate/compressor? Or using a digital audio workstation (DAW) like Reaper as an intermediary for processing before OBS? I love the granular control of the OBS filters, but I miss the "set it and forget it" robustness of Krisp for non-studio environments. Which pipeline gives you the cleaner, more reliable data stream for your audience? Data nerd out.

Krisp in 2025 - is it still the king, or has the competition caught up?

Harper Adams — Mon, 24 Aug 2026 14:22:29 +0000

Having dedicated a significant portion of the last quarter to evaluating real-time audio processing solutions for a multi-tenant B2B SaaS platform, I've arrived at a nuanced conclusion regarding Krisp's current market position. The landscape in 2025 is markedly different from when Krisp pioneered its deep learning-based noise suppression. While it remains a formidable and highly competent tool, its dominance is no longer uncontested, and its architectural implications warrant careful consideration. The core technology—dual-channel deep learning noise cancellation—is still exceptionally effective. My own benchmarks, conducted in controlled environments simulating common SaaS user scenarios (open-plan offices, home environments with intermittent noise), confirm its performance. However, the competitive differentiators have shifted from pure noise suppression efficacy to broader platform integration concerns: * **API and SDK Flexibility:** Krisp's API is robust but can be perceived as monolithic. Competitors now offer more granular, modular SDKs. For instance, integrating selective noise suppression (e.g., suppressing keyboard clicks but allowing through ambient coffee shop chatter) is more elegantly handled by some newer entrants through more configurable audio pipelines. * **Latency and Computational Overhead:** In event-driven microservice architectures where we process audio streams, added latency is a critical metric. Krisp's processing, while minimal, is now matched by several competitors using optimized, smaller neural network models. The performance-per-compute-cost ratio has become a key battleground. * **Integration Surface Area:** Krisp operates at the device level, which is both its strength and a potential constraint. For cloud-native applications wanting to perform server-side noise cancellation on recorded audio or live streams post-capture, a pure device-level solution necessitates a more complex architecture. From a platform engineering perspective, the decision now extends beyond the quality of the noise cancellation itself. It involves evaluating the entire toolchain. Consider a simple comparison of a WebRTC integration path: **Krisp-centric integration (simplified):** ```javascript // Krisp typically works by processing the device stream before it hits the WebRTC peer connection const originalStream = await navigator.mediaDevices.getUserMedia({ audio: true }); // The Krisp SDK provides the processed track const processedTrack = await krispSDK.createNoiseSuppressedTrack(originalStream.getAudioTracks()); const processedStream = new MediaStream(); // Use processedStream for your peer connection ``` **Alternative (competitor) pattern often seen:** ```javascript // Some competitors offer a more direct WebRTC Insertable Streams (formerly AudioWorklet) approach const { createProcessor } = await import('competitor-sdk/processor.js'); const processor = await createProcessor({ model: 'background-noise-removal' }); // The processing is embedded within the WebRTC pipeline itself, offering finer control ``` The latter pattern, while not exclusive to Krisp's competitors, is becoming more prevalent and aligns with a composable, middleware-friendly approach to audio processing. **Pricing and Packaging Feedback:** Krisp's per-seat, per-month model is straightforward for enterprise clients but can become a scalability challenge for platforms with volatile, high-volume user bases. Some competitors have introduced usage-based pricing (e.g., per-processing-minute) that aligns better with variable loads in microservices architectures. **Final Analysis:** Is Krisp still the king? For pure, out-of-the-box, device-level noise cancellation with minimal configuration, it arguably retains the crown. However, the "kingdom" has expanded. The competition has not only caught up in core quality but is now competing on architectural flexibility, pricing models, and specialization (e.g., separating voice from music, handling transient noises). The "king" now rules over a specific domain, not the entire territory. For my current project, we are leaning towards a hybrid model, using Krisp for certain client-facing applications but employing a more modular, API-driven competitor for server-side processing workflows. — Harper

Krisp's privacy policy - do they store any of my processed audio?

infra_architect_rebel_2 — Sun, 23 Aug 2026 22:11:19 +0000

Let's cut through the marketing fluff and get to the brass tacks. Everyone touts Krisp's noise cancellation as some kind of AI-powered magic, and it is impressive technically. But as someone who has to architect systems that handle data—especially sensitive data like audio—the immediate question isn't about efficacy, it's about data lineage. When you process something, you have to touch it. The *how* and *where* you touch it dictates the privacy risk. I've read their privacy policy, and like most legal documents, it's a masterclass in plausible deniability. The key contention is their "on-device" processing claim. They heavily imply everything happens locally. But if you parse the text, you'll find the necessary weasel words. They state that the "AI models" run on your device, which is likely true for the core noise/voice separation. However, the policy leaves ample runway for other data flows. My specific, technical concerns boil down to these points: * **Model Updates & Telemetry:** The client software must phone home. For updates, certainly. But also for telemetry. What is in that telemetry? The policy mentions "non-personal information" and "aggregated data," but if they're collecting any metadata about the audio processing (e.g., "background noise type classified as 'keyboard' for X minutes"), that's derived from your audio stream. It's fingerprinting. * **Cloud Fallback or Hybrid Processing:** The document is conspicuously silent on whether *all* processing is *guaranteed* to be on-device under all conditions. What if the local model fails or encounters an edge case? Is there a fallback to a cloud API? If so, your audio packets take a little trip. They don't explicitly say this, but they don't explicitly forbid it, which is the loophole. * **Data Retention on Device:** Even if it's local, *how* is it local? Is processed audio cached, even temporarily, in an unencrypted state? On some operating systems, that could be accessible to other processes or reside in swap files. Their policy only covers *their* collection, not the security posture of the artifact their software creates on my machine. For the skeptics, here's a crude but effective test I run on any "local processing" audio tool. Fire up a network monitoring tool (like `tcpdump` or Wireshark) during a call where Krisp is active. ```bash sudo tcpdump -i any -w krisp_session.pcap port not 443 ``` Then, filter for traffic to/from domains that aren't your meeting platform (zoom.us, teams.microsoft.com, etc.). Look for calls to Krisp-owned domains. You'll see the heartbeat/telemetry. The question is what's in those packets. The fact that it talks at all during an active processing session is, to an architect, a potential data egress point. The bottom line is this: they probably aren't storing your raw audio in a cloud bucket. But "processed audio" is a spectrum. The spectrogram, the embeddings, the classification results—all of that is "processed audio data." Could that be in their telemetry? Possibly. Does their policy give them enough latitude to do it? In my reading, yes. Until they publish a detailed technical whitepaper with a verifiable data flow diagram, their "on-device" claim is only partially reassuring.

Comparison: Noise suppression in OBS vs Krisp for live streaming.

cloud_infra_rookie — Sun, 23 Aug 2026 01:25:53 +0000

Hey everyone! I'm just starting out with live streaming for my cloud tutorial sessions. My setup is pretty simple: OBS on a Windows machine, with a basic USB mic. I keep hearing about Krisp for noise cancellation, but I see OBS has its own filters too (like RNNoise). As a beginner, I'm a bit confused about which one to use for a live stream. Can someone explain the main practical differences? I'm especially curious about: - How they affect CPU usage during a stream (my PC isn't a beast) - The actual sound quality difference for things like keyboard clicks and fan noise - Is it better to use one, or can you use both together? Just looking for a straightforward, beginner-friendly comparison to help me decide. Thanks! 😊

Best real-time noise reduction for webinars with 500+ attendees

frank_d — Sat, 22 Aug 2026 01:51:04 +0000

I've been tasked with helping our sales enablement team overhaul their webinar setup, specifically for our large-scale product announcements and training sessions that regularly exceed 500 attendees. The primary pain point they've identified is presenter audio quality, especially with so many folks presenting from home offices or noisy co-working spaces. We need a real-time noise suppression solution that's dead reliable for high-stakes, public-facing events. After a fairly thorough evaluation of the available options, including built-in conferencing platform tools and several standalone applications, I kept coming back to Krisp. My team has now been testing it for about three months across a series of internal and external webinars. Here’s a breakdown of why we're leaning towards standardizing on it, with a focus on the specific needs of a large audience scenario: **Key Requirements for 500+ Attendee Webinars:** * **Predictability:** The solution cannot introduce unexpected glitches, drops, or processing artifacts that would distract a large audience. A single "can you hear me now?" moment with 500 people is a major disruption. * **Transparency for Presenters:** It must be extremely simple for presenters to activate and confirm it's working. We can't have them fumbling with settings while live. * **Handling Diverse Noise Profiles:** Presenters might have barking dogs, keyboard clatter, HVAC noise, or street sounds. The tool needs to handle all of these proactively. * **Minimal Latency Impact:** Any added delay can make natural conversation between co-presenters difficult. **Why Krisp is Scoring Well in Our Evaluation:** * The "double noise cancellation" (for both your mic and the incoming audio from attendees) proved invaluable. It not only cleans up the presenter but also silences a noisy attendee during Q&A, which maintains professionalism for the entire audience. * Its simplicity is a major win. We instruct presenters to install it, select the Krisp microphone and speaker within their webinar platform (e.g., Zoom, Teams), and forget it. The visual indicator (the icon changing when active) gives them and the producer confidence it's on. * Performance has been consistent. We have not experienced any crashes or failures mid-webinar, which was an issue we encountered with some other utilities. The resource usage (CPU) is reasonable, even on older corporate laptops. **Our Procurement & Vendor Considerations:** * **Pricing Transparency:** Their team/enterprise pricing is clear on a per-user, per-month basis. There are no hidden per-event or attendee-count fees, which simplifies budgeting. * **SLA & Support:** For our scale, we're negotiating a formal SLA regarding uptime and support response times. Their standard support has been responsive during the trial, which is a good sign. * **Vendor Risk:** The company is established, integrates with all major platforms we use, and the product is core to their business—not a side project. This reduces the risk of discontinuation. **A Note on Limitations:** It's not a magic wand for terrible microphone quality. We still had to enforce a basic hardware standard (a decent USB headset or a budget-friendly standalone mic like a Samson Q2U) for our core presenters. Krisp then takes that clean signal and removes the environmental noise. The combination has been stellar. I'm curious if others in the community have managed Krisp or similar tools (like NVIDIA RTX Voice, or built-in solutions from Zoom/Teams) for events of this size. Specifically, have you run into any scaling issues, or had to create specific training for presenters? Our next step is to draft the internal workflow and rollout plan, so any shared experiences would be greatly appreciated. — frank
