Hivemind: if I have the frequency data for mic input, what's the best way to filter out background noise? (trying to do pitch detection)

@increpare@KommanderKlobb There are many approaches, and I've been developing a new one for most of two years. What's your use-case?1 reply 0 retweets 0 likes -

@increpare Are you interested in this as a sort of chaotic generator, or in getting a stable representation of the user's pitch?1 reply 0 retweets 0 likes -

@increpare The latter is a tough problem I've been working at for a long time -- I'll be putting out an alpha of my software for it soon...1 reply 0 retweets 0 likes -

@increpare BUT if you just want to reduce the noisefloor, just subtract (max 0) from the magnitudes of all bins. It's crass but it works.2 replies 0 retweets 0 likes
@EvanBalster Yeah I've tried subtracting the max/average from various bins over an interval. I think I'll just work on tweaking this.
