Csound does have some capacity for pitch detection. However, what it
has is a toolkit that needs to be assembled into an application with
code. There is commercial software, often with proprietary advances in
the state of the art, that is already designed to do this job, usually
as part of a mainstream audio workstation (not cheap, but not
expensive considering what you get), or as a plugin.

Caveat: None of this stuff seems to work all that well. Don't be
hasty. You might want to start by seeing what you can get to work in
Csound, then you will be up to speed with how this stuff usually works
and better informed to evaluate other software.

Regards,
Mike

I'm looking for a .csd file I put together from tinkering with one of Iain McCurdy's examples ( http://iainmccurdy.org/csound.html )
--

and as you've been told, this stuff doesn't work all that well.

What I did was input my singing directly into a .wav file (and cleaned it up a little with Audacity?) which I then played slowly to this routine for conversion to MIDI, which I then played through a fluidsynth opcode. Detecting pitch changes -- without detecting too many of them -- was a real challenge; my voice isn't as steady as I'd thought until then.

Generating a set of frequencies that produces a result that is equivalent (or close enough) to some input signal is straightforward. Mathematically, there are an infinite number of  solutions - an infinite set of combinations of frequencies that will each combine in their grouping model any given input. Detecting "the pitch" which a human ear would recognize in a sound is much much harder - there's only one answer and the relationship to the input signal is much less straightforward than intuition would lead you to believe.

Öyvind Brandtsegg was quite successful in getting their MIDI pipe organ to talk (http://theforeigner.no/pages/news/norway-academic-makes-the-organist-redundant/) using a csd he graciously provided, which I attach here copied directly from his mail from February 2013.

There are actually quite a few opcodes dedicated to tracking pitch, each with their own strengths and weaknesses. You can find a survey of them in the FLOSS manual:

http://floss.booktype.pro/csound/l-amplitude-and-pitch-tracking/

My own examples demonstrating them are here:

http://iainmccurdy.org/csound.html#PitchTracking

Humming into each of these should provide some sort of indication which opcode will work best for you. 

To convert audio into MIDI note events you will probably want to involve amplitude tracking also (some opcodes include this built-in) to detect note-ons and then note durations.

You should also consider processing of the audio before it goes into the pitch tracker - filtering, compressing and gating to remove unwanted noise and noisy note attacks if present - and smoothing and quantising of the data output to remove the element of human inaccuracy before translating to MIDI events.

I think these ancillary procedures are key to getting the best out of the pitch tracking opcodes.

Subject: [Csnd] want to convert humming to midi -- is Csound the right framework?
To: CSOUND@LISTSERV.HEANET.IE

Hi all,

I am a total newbie, so I might be asking a question that is not a good one -- I couldn't even clearly understand the results of my google searches on the matter!

I am wondering if Csound has the capacity for pitch detection? I am interested in this because I'd like to write a toy script to take some audio input (humming) and convert it into midi regardless of its original form.

Would this be possible using Csound's framework? From my google search, I found out about something called `psvpitch`:

http://www.csounds.com/manual/html/pvspitch.html

This seems to be exactly what I am looking for, unless I am misunderstanding?

Kind regards,

Brian
