Hi,
How to include fft ? Do you need to use node or may be other way ?
I don't have part server and I would like to avoid node.
Thank for respond.

In case anyone else runs into this: I noticed that the docs indicate sampleRate input as in new PitchAnalyzer(sampleRate). But in actuality, it appears that the rate of 44100 is hardcoded, and the input is not used.

In your readme it says:
"The internal buffer is 4096 samples"

However it doesn't seem like it in the code:

FFT_P	= 10,
FFT_N	= 1 << FFT_P,
BUF_N	= FFT_N * 2;

This makes BUF_N 2048. Maybe I just missed something?

What do you think of doing an annotated version of the source using docco? Obviously pitch.js isn't particularly hard to use, but I think a docco version of the source (if annotated well) could be interesting to people and help them understand the source, and maybe we'd get more outside contributors because of that. Anyway, just a thought.

Sorry about the wait on this. If I remember correctly, you need something that looks like one of those digital tuners that shows what note you're playing, the percentage error, and how loud you're playing. Did I miss anything?

Questions:

• The percentage error will be plus or minus a percentage (0 to 100) or plus or minus a decimal (0 to 1)?
• How will I get the volume? By decibels, some sort of percentage for the meter or what?
• How will I get the note? Just a string representing the note name (A, Bb, or C#) or something else?

Let me know, and I'll get coding! :)
