MultiTrim listens for the silence at the head and tail of every track, then cuts it on codec-aware boundaries. Local, lossless, batched.
Not a converter, not a generic editor. MultiTrim does one job: find the dead air at the head and tail of every track, then trim it cleanly.
Energy-based detection that ignores quiet musical passages.
Whole-frame cuts. No re-encode on the trim path.
Multi-core parallel queue.
Drag the markers yourself.
MP3, FLAC, WAV/RF64, AIFF/AIFC, AAC, and M4A AAC/ALAC.

Free covers MP3, M4A/AAC and WAV. Pro adds FLAC, WAV/RF64, AIFF/AIFC, AAC and M4A AAC/ALAC. Cuts land on whole frame boundaries, so every part of the file you didn't trim comes out bit-for-bit identical.
RMS energy over a sliding window. You set the threshold in dBFS and the minimum continuous duration. Anything below threshold for at least that long, at the head or tail of the file, gets cut. Quiet musical passages between are left alone.
No. Originals are never touched. Trimmed copies are written to your chosen output folder under your chosen naming pattern. Source files stay where they are.
That's the whole point. Pro queues as many files as you throw at it, runs them in parallel across your cores, and shows live progress for each one. Pause, resume or skip without losing your place.
Grab the head and tail markers and set them yourself. Wherever you drop them, MultiTrim snaps to a clean codec boundary before writing, so the cut never clicks.
Your audio is trimmed entirely on your own machine and never gets uploaded. You sign in on the dashboard to grab the app and manage Pro, but the files stay with you.
Free handles one file at a time in MP3, M4A/AAC and WAV. Pro drops the limits: unlimited batches and every supported format.
Desktop, on macOS, Windows and Linux. The dashboard spots what you're on and serves the right build.
