✂️ AUDIO TRIMMER + LOOPER
Loop a section. Cut a clip.
Drop a file, drag the handles, hear it on repeat. Export the trimmed clip as WAV when you've got the section you want. Runs in your browser — nothing uploaded.

How it works. The browser decodes your audio
via Web Audio API, downsamples to peak-pairs for the
waveform, and uses an
AudioBufferSourceNode with
start(when, offset, duration) for playback —
sample-accurate region playback with no re-encoding required.
Loop mode just re-fires the source with a tiny stagger
between iterations. Export writes the trimmed PCM region
into a fresh RIFF/WAVE container (16-bit PCM, source's
sample rate). Drag the handles or use the numeric inputs +
nudge buttons for precision down to 10ms.
