rusty_microphone's Issues

Autotune-like feature for improving intonation.

Hi Justin,
just tested rusty_microphone after reading your amazing blog article about it.
Thank you for both, they have been really inspiring!
Beeing a hobby flutist the intonation problem is well known to me as well - I will try the software next time I play my instrument.
But now for this issue:
Long time ago I also used to play the guitar a little. At the beginning I used one of these cheap guitar tuner-boxes that give you an optical feedback similar to rusty_microphone. But it always felt quite unprecise and time-consuming (maybe because it was just a very cheap device). Later, somebody told me the way of "flageolet tuning" that works by comparing the string-tunes using your ears and string-harmonics. This method worked very good for me and I'm asking myself, if it could work as an option for rusty_microphone as well.
After finding the nearest note, as the program already does, it should be easy to generate a sine-wave of the exact right tune and forward it to the speakers of the computer. Deviations from the instruments tone should be clearly audible as interferences.
Just an idea... not sure if it will work, especially on fast tone changes.

Keep it up!
