Photosounder Spiral

the spectrum is displayed on a spiral framed by a chromatic circle

• The colours represent position in the stereo mix which means that quite often instruments have their own colour.
• Portions of the sound can be recorded in Spiral's memory and then played back at a much slower rate (between 0% and 100%). This is quite necessary and handy when writing down notes or analysing chords.
• Analysis resolution can be adjusted. You'll want to lower it when analysis notes played very fast as it gives you more precision in time, and increase it when analysing complex chords, bass instruments or when tuning an instrument.
• The spiral visualisation can be rotated so that you may have the root of the scale on top and thus be able to recognise notes more readily.
• By clicking on the visualisation you can create overlays that represent the harmonics for a given note. Adjusting those overlays can greatly help you in identifying the individual notes that make up a chord.
