Indeed HIRT is the best IR capture package for Max. There is also HAART, which is a standalone Max application we developed using HIRT. This software is all in one box for multichannel IR capture (24 mics x 24 sources), acoustic parameter analysis and binauralisation. The analysis part is still under development, but the IR capture and binauralisation parts are fully working. You can download it here
http://eprints.hud.ac.uk/id/eprint/24579/ Also as Pierre mentioned, we captured over 2000 IRs of 39 multichannel mic array configurations from stereo to 9ch 3D using HAART. The library comes with a Max renderer where you can convolve dry sources or signals fed from DAW with the mic array IRs for simultaneous comparisons between techniques. https://github.com/APL-Huddersfield/MAIR-Library-and-Renderer Best, Hyunkook ========================================= Dr Hyunkook Lee, BMus(Tonmeister), PhD, MAES, FHEA Senior Lecturer in Music Technology Leader of the Applied Psychoacoustics Laboratory (APL) http://www.hud.ac.uk/apl http://www.hyunkooklee.com Phone: +44 (0)1484 471893 Email: h....@hud.ac.uk Office: CE 2 /14a School of Computing and Engineering University of Huddersfield Huddersfield HD1 3DH United Kingdom ________________________________________ From: Sursound [sursound-boun...@music.vt.edu] on behalf of Pierre Alexandre Tremblay [tremb...@gmail.com] Sent: 23 April 2018 09:29 To: Surround Sound discussion group Subject: Re: [Sursound] RIR measuring, how to capture a higher order Ambisonic room responce? If you use Max, try the very versatile HIRT. 2nd order with a tetramic is not possible as far as I am aware through… we have done (mega)multimic IRs (24 channels of inputs, of which a 1st order ambisonic) of 3 different spaces with our kit, and it was fun and productive to train the ear on difference of multichannel mic techniques (Hyunkook Lee has a cool setup and papers on them, and I was mostly interested in DPA LCR omni vs coincident vs MS) We did many stage positions too. I can investigate if I can share the files if that interests anyone. p > On 23 Apr 2018, at 08:37, Bo-Erik Sandholm <bosses...@gmail.com> wrote: > > I want to measure the RIR of a medium size good listening room at least up > to second order Ambisonic RIR. > > The IR result is to incorporate the responce and reflections of the > speakers and their positions. > > I have a tetramic. > > Can several measurements and rotation of the tetra mic between them be > combined to create the measurements that comes closer to a second order mic? > > I know the basics of using Audacity, and a audio sweep and creating a IR > from this. > > > > Bo-Erik Sandholm > Stockholm > -------------- next part -------------- > An HTML attachment was scrubbed... > URL: > <https://mail.music.vt.edu/mailman/private/sursound/attachments/20180423/ee496094/attachment.html> > _______________________________________________ > Sursound mailing list > Sursound@music.vt.edu > https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit > account or options, view archives and so on. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
