Common Scenarios

Voice notes

keep only the useful part of a recording.

Podcast clips

cut a short quote or intro from a longer file.

Editing handoff

choose uncompressed WAV for another editor, or 192 kbps MP3 for easier sharing.

Input & Output

Input file: one local audio file with a readable primary audio track.
Range: start and end time in seconds. The end must be later than the start.
Output: one uncompressed 16-bit PCM WAV or fixed 192 kbps MP3 file for the selected range.

Usage Advice

Keep the tab open while the WAV or MP3 file is being created.
Large audio files can use a lot of memory because the browser has to decode and rewrite the selected range.
Preview the range before export when you need a clean start or ending.

Limitations & Compatibility

Choose uncompressed 16-bit PCM WAV for editing or fixed 192 kbps MP3 for a smaller, shareable file. MP3 uses lossy compression.
This version shows a lightweight waveform overview, but the trim range is still controlled by the start and end time fields.
This tool does not fade, normalize, mix, transcribe, or join multiple segments.
