Bing! Illumination strikes. I think I know what's happening. Some years ago you, Fons, when I first got the Brahma, or possibly Ricardo (Richard Lee) or Angelo, pointed out that the original 44k1 calibration file for my Brahma was corrupt; not the right length; maybe also the 96k file, but I don't record at 96k. Since then I have used 48k sampling, or a set of calibration file done for me by Ricardo. But this year i forgot and had gone back to the original calibration file. That's why VVMic stand alone works without the noise - it only uses the new calibration file. I'll try/check with the new calibration file when I get home tonight.

In the stereo file there are discontinuities spaced 512 samples or multiples of 512 samples apart. This looks like a problem in the convolution. Please upload the B-format as well. -- FA _______________________________________________ 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. -------------- next part -------------- An HTML attachment was scrubbed...
