Spiral was meant to make you see and learn notes directly from the visualisation of music.

Spiral is a music analysis plugin. It's a fresh take on spectral analysis focused on allowing you to see and understand music and the notes that make it up instantly.

Spiral is available on both Windows and Mac, in VST and AU format, in 32 and 64 bits.
