Have an idea where artifacst come out for some IRs?
I have no idea what's wrong here? I currently don't understand partitioned convolution. My test case: ./ffplay -f lavfi "aevalsrc='if(lt(t,1), if(n,0,1), sin(1000*t*t))', aformat= channel_layouts=mono, asplit [afir_in0], firequalizer= zero_phase=on:gain_entry='entry(0, 0); entry(100, -4); entry(1000, -30); entry(5000, -50); entry(6000, -10); entry(10000, -5)', aformat= channel_layouts=mono,a split [merge1], atrim= end_sample=883 [afir_in1]; [afir_in0][afir_in1] afir, aformat=channel_layouts=mono, [merge1] amerge, asplit[out0],showspectrum=s=1024x512[out1]" Note that your old patch didn't generate artifact. Thank's. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
