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 f...

...t; >If 32 bits is not enough, the next logical amount is 64 bits. Fact is that FLAC is highly economical in items such as reserving 20 bits for sampling rate or 3 bits in the middle of the middle of a byte for number of channels (which are, in fact, currently too few for applications such as beamforming that use arrays of several dozen microphones), so the next logical amount could easily be 40 bits, which would suffice for 50 h recording at 192 kHz / 32 bits / 8 channels; or even 48 bit, which allows for 1.5 year recordings (not unlikely, however, in long-term soundscape continuous recordi...

...and increases load. The Alsa-plugins of Speex echo just don’t seem to work whilst repos using the speex libs do. https://github.com/voice-engine/ec I actually use the speex AGC Alsa-plugin as its a great tool and then run Echo via the above. Coupled to WebRTC_VAD and a python based MFCC routine. Beamforming and DOA I have given up hope for as I am running so many extremely similar FFT routines concurrently in different process space that my load usage makes me believe there isn’t a chance. All of them have extremely similar frame based spectra analysis collection that collate and process over diff...

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".
