Dear all, As part of working on making test-suite less demanding of exact FP results so my FP-contraction patch can go back into trunk and stay there, today I analyzed "MultiSource/Benchmarks/VersaBench/beamformer". I found that the raw output from that program is 2789780 bytes [i.e. ~2.7 _megabytes_] of floating-point text, which IMO is too much to put into a patch -- or at least a _civilized_ patch. ;-) As a result, I wrote the below Python program, which I think should deal with the problem fai...

Dear list, Could you please tell me the values of the minimum and maximum cutoff frequencies for each coding version of the 44.1 kHz sampled data? For instance, are the values fmin=100 Hz and fmax=12 kHz valid? Thank you very much in advance. Kind regards, ? Fernando A.

Maybe Monty will make a video about it one day and we will all understand it. ;-) Silvia.

Hi, Xiph has done some really good work but since Speex things have seemed quite quiet. Devs to hobbyists have a huge battle with VoiceAI audio processing and even when available extremely similar routines are separated across libs so that much process duplication occurs and increases load. The Alsa-plugins of Speex echo just don’t seem to work whilst repos using the speex libs do.

Presuming that you are asking regarding the Ogg Vorbis audio format, the correct answer is: there is no minimum or maximum cutoff frequency. Vorbis can code all frequencies from DC to Nyquist. What Vorbis will actually do is extremely complex, extremely nonlinear, and highly dependent on bitrate. If you are in the mentality of linear time-invariant filters, you will never be able to understand

Oh, I will be very happy if I could see this video! Thank you very much Silvia.

Well, some University in America (Rice University) has beginning a process of providing courses and books under CC licenses.

Hi all, I've started looking at the GlobalMerge pass, enabled by default on ARM and AArch64. I think we should reconsider that, at least for AArch64. As is, the pass just merges all globals together, in groups of 4KB (AArch64, 128B on ARM). At the time it was enabled, the general thinking was "it's almost free, it doesn't affect performance much, we might as well use it".
