Sound Frequency Recognition Software

Does anyone know of “free” software that takes microphone input from a user and shows what frequency said user is outputting. It would probably be used out of curiosities sake with my voice and perhaps help tuning a guitar (possible applications, who knows). I’m just curious as to whether this software exists and is “free” (ie: “available”).

      • I duno of any free ones right off, but Cakewalk Guitar Studio has a software guitar tuner. You hit an open string on the guitar and it shows how high above or below ideal it is.
  • There are also programs (some free, some not) that convert wav files to MIDI notes. These don’t work well except with instruments that have discrete notes such as pianos, but I haven’t ever tried to use any myself.

Thanks Doug, I’ll look into the Cakewalk program and see if there are similar free programs that will offer the same features. Anyone else have suggestions?

I’d probably Google for:

spectrum
sound
realtime
software
(your OS… Windows/Macintosh)

Basically you’re after a sound spectrum analyzer. I’d guess a lot of sound recording software would have a similar feature, but it wouldn’t necessarily be realtime.

I went to download.com and found a program called enable Tuner 2.6i, which is a guitar tuner that also shows the frequency of a microphone input. Unfortunately it is a 30 day evaluation copy, so it’ll only have some shortlived functionality. Oh well, at least I found what I was looking for.
