Audio Quality
Find noise, glitches, silence gaps, and clipping in your TTS output - before your users do.
The problem
TTS output isn't always clean. Providers can produce files with audio glitches, unexpected silence, or clipping - and it often happens randomly across a batch.
A provider updates their model and the overall quality drops. Files that used to sound clear now have a muffled or distant quality. Since there's no error, you only notice when someone complains.
Clicks, pops, garbled speech, static noise, and digital artifacts appear randomly in TTS output. They're easy to miss in a large batch but immediately noticeable when someone is listening to your content.
Some providers occasionally return files with long stretches of silence in the middle - or skip entire paragraphs. The API returns success, but chunks of the audio are just empty.
Every bad file costs you a generation credit. Without automated checking, you're paying for files you'll have to regenerate anyway - and you don't know which ones until someone listens to them all.
What people are saying
"I've been paying for a creator account the last two months, and while I do manage to get satisfying results, it seems to require an ever increasing amount of re-rolls to get acceptable quality."
"Audio quality sounds like I'm standing far away from the mic or something. It was so amazing at first."
"Total requested audio was 4:31, but from 1:21-2:26 and 3:02-3:36 there was only silence. Also huge volume level changes and style shifts. In short: unusable."
"Some of my texts get synthesized no problem into one neat file. Yet other books encounter problems. I get a bunch of 5-minute chunks and there seem to be a random amount of chunks missing."
How we detect it
Every file goes through a series of checks designed to catch the issues that TTS providers don't warn you about.
We measure the signal-to-noise ratio
Each file is analyzed to separate the voice from any background noise. Files with unusually low clarity get flagged - even if the noise is subtle enough to slip past a quick listen.
We scan for glitches and artifacts
We look for clicks, pops, garbled speech, static noise, and digital artifacts that TTS engines sometimes produce. Each artifact is timestamped so you know exactly where the problem is.
We check for silence gaps
Files are scanned for unexpected stretches of silence - a common issue where the TTS engine skips phrases or entire paragraphs without returning an error.
We detect clipping and bandwidth issues
We check whether the audio is clipping (distorted peaks) or has been downsampled, which can make output sound thin or compressed compared to the rest of the batch.
