Frequently Asked Questions
Is my audio data uploaded to a server?
No. This tool uses a zero-server-load architecture. All processing is done locally in your browser using the Web Audio API, so your data stays private.
Does this tool lower the audio quality?
No. The tool performs non-destructive editing on the audio buffer. The exported WAV file maintains the original sample rate of your recording.
What is the best sensitivity setting?
For clean studio recordings, a low threshold (around 1%) works best. For recordings with background hiss, you may need to increase the threshold to ensure the engine ignores the noise.
Is there a file size limit?
To prevent browser crashes, we recommend files under 50MB. Because the audio is decoded into your RAM, very large files may cause the tab to refresh.
Does it support stereo audio?
Yes, the engine analyzes the primary channel for silence but preserves all original channels during the trimming process.
Is this tool free for commercial use?
Absolutely. This is a free utility designed for podcasters and voiceover artists to speed up their post-production workflow.
