soundmems & FHT support

[Yariv-h]

are there any plans to add the support of http://wiki.openmusiclabs.com/wiki/ArduinoFHT ?

Not sure what you mean, as I do include an example that uses the (most excellent) FHT library in fht_log.ino. I'm looking to update that example with high speed A/D acquisition in the next couple of weeks when I get a chance.

In the meantime, I just published another repo with much better A/D acquisition that also uses the Open Music Labs FHT library.

Oh, and whoever wrote that FHT library is a genius.

:) definitely! looking forward to that!!

I have a small piece of code that encapsulates the FHT lib I successfully integrate it with your effect, will try to create a branch in your repo and will contribute this part :)

In the meantime, my program called 'notasound' (which is in the repo) contains my most recent non-FHT/FFT based sound reactive demos.

Will add it to there :)

Sounds interesting. In the meantime, my philosophy is that my display routines:

• Fit on an Arduino Nano.
• Do not use delay statements.
• Define each variable as locally and as tightly as possible, i.e. uint8_t instead of a poorly defined int.
• Variables are all localized unless they are used elsewhere.
• No floats.
• No nested loops.
• Use math instead of pixel counting i.e. fast sine routines to move LED's.
• The routines need to be short.
• The fps needs to be very high.
