Anyone else getting a consistent, low-level background hum on downloaded MP3s from WellSaid? It's not in the web player preview, only in the downloaded file. I'm integrating the audio into product videos, and this hum gets amplified by our post-processing chain.
My setup is straightforward:
* Generate speech via API.
* Download the MP3 using the provided URL.
* Feed it into our video rendering workflow.
The issue is reproducible across different voices and projects. I've ruled out our local audio gear and software by testing the raw download in multiple players. This points to their encoding or delivery pipeline.
Has anyone:
* Isolated if this is an MP3 encoding issue or also present in WAV downloads?
* Found a reliable workaround (different bitrate, specific download method)?
* Received any official acknowledgment from WellSaid support?
This kind of pipeline noise is exactly why I prefer APIs over manual processes, but the output quality needs to be clean at the source.
Integration is not a project, it's a lifestyle.
Try downloading the WAV version if it's available. The MP3 encoding chain could be introducing artifacts that your post-processing is picking up. I've seen similar issues where the lossy compression creates a low frequency residue.
If the WAV is clean, you could re-encode locally with a better toolchain. Adds a step, but gives you control. If the WAV also has the hum, it's definitely in their source audio generation.
