I am working on a project in Max where I need to convert audio input into MIDI output, similar to the functionality shown in this video:

In the video, the patch appears to be capable of detecting and outputting multiple pitches simultaneously, which is exactly what I am aiming to achieve.

From my understanding and previous experience, objects like sigmund~ and fiddle~ are designed for monophonic pitch detection. However, the example in the video suggests a capability for polyphonic pitch detection.

Could anyone advise on how to approach building or modifying a patch that can handle polyphonic audio to MIDI conversion? Are there specific objects or external libraries in Max that are suited for this purpose? Any tips on managing the data to ensure accurate pitch detection and output would also be greatly appreciated.

that noisy terrible screaming voice false triggers a bunch of frequencies

there is technically optimized pitch tracking and there is interesting arts, and there is no rule which says that you could do both in one patch.

Gratitude to you both for your insightful responses!

Initially, I assumed that the 'audiotomidi' patch within the video dealt with analyzing the audio input through Fast Fourier Transform (FFT), subsequently selecting and playing back specific peak frequencies as corresponding MIDI notes. 

However, if pitch detection is not its primary function in this case, how does the audio trigger the midi notes, which audibly associated with the audio input in the patch? 

there is probably some sort of ->pitch following or spectral analysis involved here, but obviously extrapolated. 

and that second characteristic you are looking for is ->transient (attack) detection.

however, this stuff sounds so interestig because the code is imperfect.
