When the stack builder picks it
The builder reads each job's rules from the top and takes the first step whose conditions hold and whose plan fits the money left. Klangio is named in these steps:
- Audio to notes, step 4 of 4, otherwise: Studio Pro ($19.99/mo); the step also names AnthemScore, and the best score takes it.
The rules are public in stack-rules.json, and how the stack builder scores explains the tie-break.
Alternatives the same rules name
- AnthemScore: Finds the notes, beats and instruments in a recording and writes editable sheet music, tabs, MusicXML and MIDI. From $39 once.
