MultiTrim listens for the silence at the head and tail of every track in your music library, then quietly cuts it out. RMS-based, 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.
Frame-accurate cuts. No re-encode.
Multi-core parallel queue.
Drag the markers yourself.
Native macOS engine per format. Metadata preserved on every write.
Try the free version first. Upgrade when you’re ready to batch the whole library.
No card. No trial timer.

Free supports MP3, M4A and WAV. Pro adds FLAC, AIFF, APE, WavPack, Ogg Vorbis and Opus. MP3 cuts are frame-aligned so the output is bit-identical to the input on every untouched frame.
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.
Yes — that’s the point. Pro queues unlimited files, runs them in parallel across your cores, and shows live progress per file. You can pause, resume or skip without losing the queue.
Open the file in the waveform editor and drag the head and tail markers yourself. Per-file overrides are remembered and survive the batch run.
No. Everything runs locally. No uploads, no telemetry, no account. Your files never leave the Mac.
Free is one file at a time, basic formats. Pro is unlimited — files, batches, sample rates, bit depth. Process a 4-hour 192 kHz/24-bit DSD rip if you want.
