Audio & files / Wave Trim
Keep the part of a WAV recording you need
Trim a mono or stereo WAV, add optional fades, and save a 16-bit PCM clip. Audio processing stays in your browser, with no upload or account.
Listen and keep the clip
The result is 16-bit PCM WAV. Playback starts only when you press Play.
Keep the part you need
A shorter sound, with a gentler start or finish.
Trim silence, isolate a short recording, or prepare a sound for another project. Choose the interval in seconds and add a linear fade at either end if you want one.
Every adjustment uses the original loaded audio. Changing the selection stops the old preview and clears the previous output, so the next download matches the settings you applied.
Which WAV files are supported?
Basic little-endian RIFF/WAVE files: 8/16/24/32-bit PCM integer or 32-bit IEEE float, mono or stereo, from 8,000 to 192,000 Hz. The file must be at most 32 MiB and ten minutes. MP3, compressed WAV, RF64, extensible WAV, and multichannel audio are not supported.
What changes in the output?
The clip keeps the source sample rate and channel count and is written as 16-bit PCM. Higher-precision input is quantized to 16 bits; no dithering or resampling is applied. Extra metadata, markers, and loop information are omitted. Float samples beyond full scale are clipped and counted.
How precise are the cut points?
Times accept up to six decimal places and snap to the nearest audio frame. The end boundary is exclusive. The result shows its actual frame count and start/end times. This preserves complete stereo frames.
How do fades work?
Each fade is linear in amplitude, up to five seconds. A fade starts or ends at zero amplitude. Their combined length must fit inside the clip. A zero-length fade leaves that end unchanged.
