Join selected audio clips locally
Arrange included selections in order and export one WAV without uploading your recordings.
Build the clip list
Each imported source starts as a full-length clip. Trim it, then Duplicate selection to make another independent selection referencing the same decoded source. Select clips to edit them, include/exclude with checkboxes, and use up/down buttons for join order. Removed clips can be restored with Undo while their decoded originals remain loaded.
Choose conversion
Choose 16,000, 22,050, 44,100 or 48,000 Hz, and mono or stereo. Same-rate frames are copied without resampling. Other rates use a 32-tap, 512-phase Hann-windowed sinc with edge clamping and a 0.94 × min(1,output/input) cutoff. Stereo-to-mono averages L/R; mono-to-stereo duplicates the source. No multichannel import is supported.
Understand boundaries
Each clip output length is max(1, round(selected source frames × output rate / source rate)); these lengths are summed in queue order. Joins are hard sequential boundaries without overlap or crossfade. Abrupt differences can click; apply a fade-out/fade-in per clip if appropriate. Fades alter audio and cannot guarantee an inaudible join.
