Before trimming
Work from the highest quality copy available and keep the original. Identify the exact moment listening with headphones when there are soft voices, breathing or musical transitions.
Cropping steps
- Open the audio trimmer.
- Select a file that the browser can play.
- Moves the start to just before the payload.
- Adjust the ending leaving a natural exit.
- Listen to the range and download the WAV.
Why is the result WAV
WAV offers broad compatibility and avoids adding another layer of lossy compression during trimming. The file may be larger than a MP3 or M4A. If the destination requires another format, convert a copy later.
Common errors
Cut too close to a word
Leave a few hundredths before and after. An exact cut on the wave can create a sharp entry.
Confusing cropping with reducing noise
Trim removes time at the beginning or end; It does not erase background noise or separate voices.
