stable FFT library?

Using Arduino Project Guidance
#1

I really don't want to have to build my own. I've tried a few on the web but have been having difficulty with crashes.

Can someone point me to a stable FFT library?

Thanks

Is plainFFT useful to you?

I've not used it myself, but did read the blog entry (links off the Arduino playground pages) with interest.

Cheers ! Geoff

Geoff,
Thanks for that link, it looks interesting and I had not found it before.

note: there is a problem with recursive call of function.
it goes overflood.
so it would better to reset vReal and vImag arrays for each call.

I've never had this one crash: http://wiki.openmusiclabs.com/wiki/ArduinoFFT

Note that if you take the standard example, you have to rewrite the output using a loop, and serial.print rather than .write, otherwise you get nonsense on the screen. Example - Open Music Labs Wiki
