Audio into CC??

[aquanaut]

Is there a way to transform audio into CC?. Is there a software that can analyse the amplitude of a signal and output a controller curve accordingly?

It wouldn't make sense, given the slow rate of midi. You couldn't make a CC change state fast enough to create audio out of it.
It's possible to track the amplitude of a signal using an envelope follower, such as on the nord modular. And, on the G2 you could then convert that to a midi cc. You can also track the pitch (of a clean signal) and use that to drive an oscillator.
But in general, trying to get midi out of audio is a lost cause, except in very specialized circumstances (i.e. you don't care if the ultimate output sounds anything like the original audio).

i'm a huuuuge fan of reaktor so here's the reaktor solution:

get your audio signal, use a audio-to-event converter and then multiply the signal by a user-controlled constant to get the range you want.

you can also do this in maxmsp with a bit more control. for instance make an fft patch, inside it use the snapshot object to sample amplitude and frequency values separately and then multiply by a constant like in the other example. You'll then have to control signals one from amplitude and one from pitch.

the advantage to the reaktor solution is that the resolution of the control signal will be better but there's no fft in reaktor.

back from a walk, ordered by my girlfriend, to calm a ****** temper tantrum causes by my incapacity to replicate the amen break on my drum machine. My stuff does'nt groove like i want it to and now it's getting on my nerve. The frustration is fed by the fact that i feel that it's one the few thing that blocks me from producing. Well...I'm tired of being in a no groove status with a nagging Squarepusher bassline in my head

I hate computers and softsynth deeply, partly because my mac can't support them and because i'm totally overwhelmed by them and also because i love being surrounded by machine. If i can't do something with an hardware then...

Thanks both for your insight on this. I would have liked my beautiful singing voice to generate CC.

if you have reaktor or maxmsp I'd be glad to build the patch for you. i've done it a million times


i think i've been in the place you're at before. not that you've asked for advice but...

...try making total nonsense. use the tools u have in new ways. just play it like you'd play a video game or with the spirit of doodling. it's unreal the power of this kind of playing. it can really open doors. why do you think actors do silly excercises before performing?

and another question: why would you want to emulate the amen? it's been done and done again. i bet you have some wonderful original sounds and sequences just waiting for the opportunity to escape =)

I asked the man: do you know someone who makes beats around. He said:...yeah...mmmut...
it's a closed paranoid circle around here.
GIVE ME THE GODDDAMMM GROOVE i said
he took his bike off the curb and i had to buy some beer.
=========
I think that understanding the amen and being able to do it from scratch would enable me to go in another direction. Like when i had to transcribe Charlie Parker. That was'nt i success. I think i was able to do a bit of Miles Davis
========
One think i admire of Squarepusher is the sort of ironic jazzy playback...a mix of laughin at the performance and having one.
==========
I like to think that i'm the only one with a sampler and a drum machine.
=========
Yesterday it was all eureka. There's something weird going on with the swing function in the drum machine. you put swing at 80% on the 8 th note and then 154 happens before 148 wich kinda becomes 180. I'm gonna fiddle with this a bit more. mmmut...
===========
Did i said to somebody on this forum to agonise with a tempo track until it grooves no doubt...who me

if you are looking to use your viola as a general midi controller with accurate pitch and velocity values then you will be very disapointed. Making these kinds of conversions accurate is very difficult especially with richly timbred instruments like viola or voice.

I haven't yet tried to create a pitch to midi note value convertor using fft. this will have to be implemented in max.

Accuracy is not a concern for me. In my current band, I manipulate our violinist's audio as it passes through a Nord Micromodular, using the knobs and MIDI CC coming from my iBook software (currently Numerology, using it's TripleXY controller module).

In the near future, I would like to experiment with processing my own electric violin audio through the Nord, but with MIDI CC being generated in some automatic fashion. MIDI CC values extracted from incoming audio is one approach I would like to try. My original idea with ~fiddle was to map MIDI information extracted from the incoming audio to control parameters - if I had succeeded in getting usable MIDI velocity and pitch bend values I probably would have remapped them to CC anyway.
