Ciao Øyvind,
It seems very interesting to me...! I will study it carefully.
Thank you for your reply,

Hello all, I found this reverb-application based on recorded room/space impulse responses by Ian McCurdy, 2012 . After some modifications (no Cabbage UI) I succeeded to get it work in linux/jack environment. Very interesting indeed. There is a link in the csd-file to some recorded responses. Unfortunately many of those are in b-format (4 channels) and sampling frequency in those is 96 kHz. The transformation from b-format to 2-channel stereo should be easy with the given Matlab/Octave scripts. For sampling frequency downshifting I would like to get some information. The most simple method would be to calculate straight line continuous time functions in 96 kHz time intervals and sample that to the 44.1 kHz time interval. Probably some filtering would also be needed. So if anyone of you have done sampling frequency modifications, please give your recommendations. --Risto |

Have you considered using the sox or ffmpeg utilities to preprocess the files? ----------------------------------------------------- Michael GoginsIrreducible Productions http://michaelgogins.tumblr.com Michael dot Gogins at gmail dot com On Fri, Aug 30, 2024 at 1:05 PM Risto Kuusisto <rjzkuusisto@gmail.com> wrote:

You can both convert from B-format to multichannel and resample in Csound.
The opcodes diskin or diskin2 allow resampling of an input file and the bformartdec opcodes can decode into multichannel or stereo.

Thanks for both of you. I already tried sox. Sample rate conversion was a piece of cake for that. It's even better if I can do both conversions in csound without external programs. --Risto pe 30. elok. 2024 klo 21.49 Victor Lazzarini (000010b17ddd988e-dmarc-request@listserv.heanet.ie) kirjoitti:

| You can do everything in Csound, including sticking the resulting IR in a function table ready for ftconv. Prof. Victor Lazzarini Maynooth University Ireland On 30 Aug 2024, at 20:02, Risto Kuusisto <rjzkuusisto@gmail.com> wrote:
