Frequently Asked Questions
How accurate is chord detection?
Works best on clearly tonal music with defined harmonic content. Electronic music with heavy bass may benefit from the kick filter toggle, which reduces low-frequency interference.
Does it detect chord inversions?
It identifies root chord names (Am, G, C). Inversions and extended chords (7ths, 9ths) may be simplified to their root triad.
Is my audio uploaded to a server?
No. All processing runs directly on your device using your own GPU or CPU. Your files never leave your machine — not even temporarily.
