Track Exploder1.1.15

Track Exploder separates the individual voices in a stereo barbershop track, aligns them, and lets you create practice mixes from the results.

Its four-part mixer can solo a voice or leave it out while the other parts continue playing, with controls for level, stereo position, channel, muting, and inclusion. Waveforms for each part preview the arrangement, and playback can be reduced to 0.5× while preserving pitch. Mix configurations can be saved as reusable presets, then used to export one mix or generate several mixes in bulk.

Exports are available as WAV or FLAC files, with the shared tags from the source tracks retained. If the part files begin at different points, the app measures their offsets and aligns them automatically; spoken introductions and pitch pipes stay together, and each part’s adjustment is displayed for manual fine-tuning. This suits barbershop singers, quartet coaches, and learners practising entrances or concentrating on specific voices.
