Cantavo Turns Your Own Songs Into Vocal Practice Rooms

Field notes

Cantavo asks singers to bring an audio or video file rather than choose from a fixed catalog. It separates vocals, drums, bass, and other instruments, then overlays the singer’s detected pitch on moving target notes; difficult notes can open looping exercises. The page also describes transposition across a six-semitone range, slower playback without pitch distortion, recorded takes, harmony layers, and a four-level Do-Re-Mi measurement set. Microphone analysis is stated to remain on the phone.
