Re: [Gumstix-users] A thought on Audio frequency analysis

[hypo <hyp...@gm...>]

before you start spending time coding on the overo, i would highly recommend
you try your algorithm out in matlab (if you have access to it). I would
suggest that you should you consider "coding" on an embedded system only
when you have completely nailed down the exact algorithm.

otherwise, you might end up fighting with too many issues: hardware /
software / algorithm and debugging might be a major headache.
