Origin and use: These simple synthesized files were generated for the CleanStems controlled quality test. They do not contain a commercial recording or human vocal performance and may be used to reproduce this listening exercise.

Listen to Each Part

Lead proxy

Synthesized melodic reference.

Backing

Synthesized accompaniment reference.

Complete mix

Lossless mixed input.

Practice Tasks

  1. Listen to the mixed input and identify when the lead differs from the backing.
  2. Compare the known lead and backing reference clips.
  3. Open the mix in Audio Looper and repeat a short region.
  4. Use Key Finder only as an experimental estimate, then confirm by listening.

For the processing experiment performed on the same clips, read the WAV versus MP3 controlled test.
