Probably a tall order, but if I have a non-MIDI keyboard, is there any
software that analyzes the audio and generates MIDI? For monophonic
noise at least? :)

i think that clam can do something like that.
but AFAIK not in real time.

There are a few these days, but the only one I have ever used is
aubionotes, from the aubio package.

Thanks. I didn't know about aubio, though apparently it has been
around for ages.
Setting up aubionotes is very easy. Unfortunately, it doesn't work
quite well enough for me (pitch detection is error-prone). But it is
probably possible to fine-tune the detection parameters by going to
libaubio directly (aubionotes doesn't have too many options to tweak,
and the ones available aren't documented).
How did you use aubionotes? Any special tips?

What type of signal did you run to it? You could try a compressor in
front of it; I think that helped. I can't remember if filtering
helped. Maybe a bandpass tuned to your expected input, or a
combination of high- and lowpass?

While I wasn't trying to do this in real time, I tried a number of apps
that were supposed to be able translate audio to music notation. I
second the bandpass filter idea, or other filtering, to clean up the
frequency range before the pitch recognition phase. I don't know what
impact that might have on RT performance, though.

Hello Dan,
Rakarrack can do this. But I bet PureData can do it too and that there
are scripts available.
Best,

PureData can do this with the fiddle~ object. I can send a small
example patch if you'd like.

Perhaps even send to list... since PD patches are essentially just txt

Or CC me.. :-)

New subject: m4a file conversion. Did Apple lock it up ?
A few days ago my daughter had an organ recital. I should have brought some kind
of recording device, but when I got there I only had my Iphone. It has a voice
recording app. I think I actually did capture it, but when I migrate the file
to my computer what I get is an m4a file for which I'm not finding
appropriate software.
I'd like to convert it to a wav file so that I can try to enhance it with audacity.
Conversion software that I tried...failed.
Anyone know a sure fire way to convert it ?

what operating system are you using?
i use ubuntu, and it includes several applications for working with .m4a files:
http://packages.ubuntu.com/search?suite=maverick§ion=all&arch=a…
of which the following looks the most useful:
http://packages.ubuntu.com/maverick/pacpl
which is a command-line application as far as i can tell

Found an m4a file on one of my old hard disks. Sure enough, Audacity
wouldn't import it, even though it tried to use ffmpeg. But vlc and
mplayer played it fine. The quickest thing to do is one of these two
commands:
mplayer -vo null -ao pcm:fast:file=file.wav file.m4a
or even simpler,
ffmpeg -i file.m4a file.wav
If you're not comfortable with command line stuff, install vlc, run it,
open the m4a file, verify it plays as you expect, and then File ->
Convert/Save and convert it to a WAV file there (select WAV for both
encapsulation and codec).
The resulting file in all three cases opened fine in Audacity.

Not sure if this would help, but you could try testing it with different
patches running on the keyboard. E.g. a pure sine patch might be easier
for the software to recognise than a complex synth patch.
