About the Audio Silence Remover
Recordings made by talking are full of pauses, and long gaps waste the listener's time. This tool finds the stretches that stay quieter than a level you choose for longer than a minimum time and cuts them out, leaving a short natural pause at each cut so words do not run together. Set the level in decibels (minus 45 is a good start for speech), the shortest gap that counts and how much pause to keep, then listen to the result and download it as a WAV file. You see how many seconds were removed and where. The audio is decoded and edited in your browser, so your recording is never uploaded.

Finding the right settings
Run the tool with the starting values and listen. If long pauses are still there, lower the minimum gap, so shorter pauses are cut too. If it sounds choppy, raise the pause kept or the minimum gap. If background noise hides the silence, raise the level toward -35 dB so the noise counts as quiet.
Remember the level is measured against the loudest possible signal. Speech recorded very quietly may sit at -40 dB, so set the level below the quietest word you want to keep.
Do a first pass with the default values, listen to the whole result once, then tune. Check the places where the speaker takes a breath or pauses for effect, because those are the pauses you may want to keep. If the result removes too little, the room noise may be above your level. A recording made with a headset microphone has a much lower noise floor than one made with a laptop.

Frequently asked questions
What level should I choose for silence?
For clean speech, -45 dB is a good start. If your room is noisy and nothing is cut, raise it to -35 or -30. If words are being clipped, lower it to -55.
Why keep a little pause?
Cutting silence completely makes speech sound rushed and chopped. Leaving 0.2 to 0.4 seconds at each cut keeps a natural rhythm.
Will it cut breaths?
Quiet breaths between phrases may be treated as silence if they are below your level. Lower the level or increase the pause kept if breaths sound cut off.
Can it remove silence at the start and end?
Yes. Silence at the beginning and end of the file is removed if it is longer than your minimum, with the same pause kept.
What format do I get?
A WAV file with no quality loss. It is larger than an MP3. Convert it afterwards if you need a small file.
Does it work on music?
It can, but music rarely has true silence. It is meant for speech, lectures, interviews and voice notes.
Is the file uploaded?
No.
