Pitch Detector documentation/example?

[lucasburkholder]

Huge fan of this library. I just am a little confused about how to use the tPeriodDetection and tDualPitchDetector modules. tPeriodDetection_init() and tDualPitchDetector_init() both take in an input buffer and buffer size arguments, and tPeriodDetection_init() also takes in a separate frame size argument that is confusing me a little as well.

What are these used for, and how can I determine the right sizes for these arguments and buffers? The comments for tPeriodDetection don't seem to say anything, and this documentation doesn't include the tPeriodDetection_init() function. I assume these arguments don't refer to actual buffers of audio that get passed into the object, since tPerioDetection_tick() just takes in a single input sample, right?

Let me know if there are any examples or documentation somewhere that I'm missing. Thanks for your help!

Hi, Thanks for reaching out! I’ll look at it tomorrow and get back to you. I can’t remember offhand. They are about the internal buffer sizes, since they do operate per sample Composer, musician, instrument designer scattershot.org * @snyderphonics

Okay that makes sense, thanks. So basically the user just allocates/frees the buffer and passes the object a pointer to it, rather than the object allocating its own?

If you are able to take a look and let me know, that'd be super helpful. Thanks so much!
