How to use it
- Drop all the files together; they are appended in the order you selected them. Add more at any time with Open files.
- Reorder in the clip strip under the waveform: select a clip and use Move left/right, or drag it.
- In Clip, set Crossfade at joins (for example 500 ms for music, 0 for speech) and press Apply to all joins.
- Listen across each join with Loop on a short selection.
- Export the whole timeline.
Crossfades that keep the level steady
A crossfade overlaps the end of one clip with the start of the next. MusicCutter uses an equal-power curve, so the combined loudness stays constant across the overlap rather than dipping in the middle as a linear crossfade does with unrelated material. The overlap shortens the total length by the crossfade time, and the counter shows the new length immediately.
With crossfade at 0, clips butt together. Unless the two sides are continuous audio from the same file, a 3 ms de-click ramp is applied so the join does not pop.
Different sample rates and channels
The project uses the sample rate of the first file. Later files at other rates are converted with a windowed-sinc resampler when they are added, and mono files are played on both channels of a stereo project. The import note under each file tells you when this happened.
Questions
Is there a limit to how many files I can join?
There is no fixed count; the limit is total length versus your device memory. A warning appears for very large projects.
Can I join MP3 files without re-encoding?
No. Files are decoded, joined and encoded once on export. Export WAV if you want no further quality loss.
Can I put silence between files?
Not directly yet. As a workaround, record or import a short silent file and place it between clips.
