FAQ
Audio Trimmer questions
Can I trim audio online for free?
Yes. The Audio Trimmer lets you cut a browser-supported audio file and download a trimmed WAV copy for free.
Can I cut an MP3 file online?
Yes, if your browser can decode the MP3 file. The exported clip is rendered as a WAV file so it is broadly compatible with transcription and editing workflows.
Does trimming upload my audio to a server?
The trimming step runs locally in your browser. If you later choose to transcribe the clip, that separate transcription upload is handled by InstantTranscriber.
Should I trim audio before transcription?
Often, yes. Trimming removes dead air and irrelevant sections, which makes the transcript easier to review and keeps the processed audio shorter.
