Preparing OGG for a cleaner MIDI result
- Use the highest-quality OGG source you have, especially for quiet instruments or sustained notes.
- A clear single melody, vocal, or instrument line usually needs less cleanup than a dense finished mix.
- Trim long silence and unrelated sections before uploading so the transcription focuses on the passage you need.
- Layered game ambience and sound effects can create extra notes; isolate the musical stem when possible.
