Sound suggestions [original from Bitkarrot]

Hi @asherp , here are some ideas to help Audiolizer sound better.

C Major keys - One simple way is to use just all the keys in the C major for every step. So the keys would be C,D,E,F,G,A,B,C or all white keys on a piano. If its all white keys, whatever you play should be good harmonics. Technically its not all whole steps, so the frequencies aren't evenly spaced -- there's a half step between E and F and B and C, but that's just a minor detail.
Using percussion instruments or similar types - If you want to stick with exact frequencies, Instead of using a synth sound, try using a percussion or bells, these tend to mask or offset harmonics that don't sound as nice.
Volume as an indicator - for acceleration in price increase or decrease.
3rd, and 5th chords or octaves - mapped to Fibonacci levels. For Example, when the price reaches a resistance or support level you can emphasize this by playing a octave, that gives more weight to the price level. E.g. C3 and C4 played together at the same time.

It might take some tweaking but Hope this helps.
