- DDSP: Approximately 10-15 minutes of clean, monophonic recordings. Ideally with MIDI transcription (or easy to be transcribed). Best for single instrument timbres.
- RAVE: 2-3 hours of clean, high-quality coherent audio (single style). Works with diverse sound types and can handle more complex timbres.
- AFTER: Typically more than 1 hour of audio samples for good results, ideally with MIDI transcription (or easy to be transcribed). Supports polyphonic content.
