Frequently Asked Questions
How is silence detected in an audio track?
The analyzer divides the audio buffer into 100ms frames and calculates Root Mean Square (RMS) amplitude. Frames remaining below the -36 dBFS threshold for 300ms or longer are registered as silent pauses.
Can I export silence cue points for podcast editing?
Yes. The "Export Cue Points" button generates a JSON array of start and end timestamps that can be imported into automated audio editors or DAWs (Audacity, Reaper) to trim pauses.
