-------------------------------------------------------------------
please share good working IR files for the c0 here.
(by that i mean tested IR files with the right length, in relation
to the sample rate. maximum for the c0 is 12000 samples.)
96000hz = 125 ms max.
48000hz = 250 ms max.
44100hz = 272 ms max.
22050hz = 544 ms max.
12000hz = 1000 ms max.
the files must be 16bit mono wav files.
user tbecker made a great python script for sample conversion:
viewtopic.php?p=2295868#2295868
i will try and keep this first post updated, collect the files and
store it for download. please add some info in a text file to the
IR files and name it in mungo tradition W0.wav to W9.wav.

if you have tips and suggestions please comment. this could be
an awesome user sharing library for an awesome module!!
-------------------------------------------------------------------

btw i am not working for mungo, i just like his modules very much!

i added a set of IR from various boxes, a hose and a glassbottle.
i made them from running sweeps through different effects i have.
here's a short demo:

nobody seems to be interested in this thread, so i probably will delete the public files soon. is the c0 so unpopular...?

it looks like it was just recently added to the US distributor stock....
give us a few weeks to save up our $

noooooo don't delete it :(
will add some soon, but don't have time at the moment

Ya seriously. If this thread gets enough IR files i'll go out and buy a C0, but i'm definetely too lazy/busy to make them myself so just waiting to see what happens here. Please keep the thread alive and keep adding. I certainly appreciate it very much!

timoka · Post by **timoka** » Mon Jul 25, 2016 3:08 pm

the thing is, the really good ir files aren't free, they come with expensive software or as paid bundles.
and very small rooms and spaces, bodies and eq's aren't that common but they are perfect for the c0.
of course people could just buy these ir files...but i would like to see some sort of community built library.
we'll see how this developes...

Sweet Deus, Mungo actually enabled the c0 to load impulse responses?

...this is bad news for my wallet.

Please report back if anyone manages to load Altiverb IRs onto this badboy. This may be a game-changer.

here is the c0 thread: viewtopic.php?t=159136&sid=3898da2bb2a3 ... c91d6cf2fa
it handles 16bit mono wav files with a maximum lenght of 12000 samples, that's only really good for room IR and smaller, weirder stuff.

timoka · Post by **timoka** » Mon Jul 25, 2016 3:27 pm

btw here's the link to all the fokke van saane IR files, they are really great, although mostly stereo and too long for the c0:

Hmm. That limitation may be enough to rule out Altiverb IRs entirely, which is a bloody shame.

Best convolution reverb program known to man.

I ordered a C0 the first day they arrived in the US, should be at my door tomorrow.
Please don't delete the files. Give it a little time. It will probably take a few weeks for everyone to order a C0 and hopefully start contributing files.

oh oh, ok, i don't delete them, i didnt realize that the US only just got the c0.

well as much fun as it's been just running signals through arbitrary wav files loaded onto the SD card, I am curious to make and post sensible IR's that conform specifically to the mandated time scale.

so just to check (as I'm terrible at this kind of thing).. at 48hz the IR should be 0.25s long yes?

as in:

12,000 samples in seconds at 48hz=
12,000/48,000 = 0.25seconds ?

I realise the sample rate doesn't matter but I have to pick one so just making sure the length of these IR's is going to be correct in terms I can easily measure.

timoka · Post by **timoka** » Tue Jul 26, 2016 3:30 pm

yes, that's right

96000hz = 125 ms max. = 12000 samples
48000hz = 250 ms max. = 12000 samples
44100hz = 272 ms max. = 12000 samples
22050hz = 544 ms max. = 12000 samples
12000hz = 1000 ms max.= 12000 samples

if you have audacity then it is even easier, you can display the length of your audio file in samples
and change samplerate to any arbitrary number to have exactly 12000 samples.
but tbecker just released a python script and it should do all the work for you (as soon as the dc offset is gone):

i made some wavs today from bird recordings. some birds create very virtuosic patterns in a very short time at a very high pitch. perfectly suited for the c0 and it's downsampling possibility!

pyjamarama · Post by **pyjamarama** » Tue Jul 26, 2016 3:56 pm

thanks timoka, I'd be interested to hear your bird recordings! really like the sound clips you've posted in general btw. really just exellent things!!

pyjamarama · Post by **pyjamarama** » Tue Jul 26, 2016 5:56 pm

I actually really like the idea of creating IR's from sounds that are not verbs at all. for the bird sounds, did you convolve/deconvolve with a sweep and create an IR or did you use a straight sample on to the flash card?

I'm wondering what the difference would be when comparing the two in the c0. any thoughts on this?

because to extract an IR from audio samples as opposed to physical spaces would require software that will convolve and deconvolve. ...and unfortunately altiverb uses a proprietary format and space designer (along with apple's associated IR utility) appear to be obsolete or at least unavailable to non logic users.

timoka · Post by **timoka** » Tue Jul 26, 2016 6:11 pm

no, i just used the samples, but i equalized them quite a bit since some frequencies ring much harder than others...and rolled off the low end.
i did a few tests with match eq and created ir from a bird call spectrum or so, that's quite different and also very interesting. i also tried to make my own primitive customs scales that way, made an ir from a eq which has for example the natural harmonics peaking and everything else cut...now when you run white noise through the c0 you get a chord-ish sound, with sine waves and precise attenuation you hear the natural scale when sweeping through the file...there's alot to try!

pyjamarama · Post by **pyjamarama** » Tue Jul 26, 2016 8:57 pm

ok well here is a small batch of resonant chambers including tigers chest cavity for fun.

they are a little raw I'm afraid while I feel out a good workflow for batch processing IR's but it's a start.

I experimented with time stretching some of the source files to fit the sample rate hoping for interesting anomalies but will try some different approaches too. a more traditional pitching approach would better preserve the timbres.

I found most worked best when the c0 was clocked and pitched to the same source as the input signal. but given the range of all parameters that's something of an arbitrary side note. chances are everyone will get radically different results from the same IR's. which is kind of great.

ah yes much better this way.

below IR's of prepared piano I recorded some years ago. some interesting cascading effects amongst other things:

thanks @pyjamarama,
i updated first post!

very nice pyjamarama, the prepared piano is very cool!
thanks

timoka · Post by **timoka** » Wed Jul 27, 2016 10:24 am

i made a short demo of the prepared piano files from pyjamarama:

http://soundcloud.com/uzala/c0-prepared-piano

trigger into res4, res4 into c0. i used both outputs from c0. sometimes with feedback loop. i sent the same pitch cv to res4 and c0.

I just ordered the last c0 from Perfect Circuit - very much looking forward to trying this stuff out and playing with you folks, thanks so much for sharing all this work!
