similar to: [PATCH] Support 56kHz to 19.2kHz gain analysis (Patch v4)

Copy additional filter values from Foobar2000 as found in <http://code.google.com/p/sirens2/source/browse/trunk/libwavpack-4.32.psp/wvgain.c?r=32> to allow metaflac to perform gain analysis on high sample rate audio. -------------- next part -------------- An HTML attachment was scrubbed...

The test is rather simple, and only compares the computed output values for a 1kHz signal at the known filter table sampling frequencies with previously obained golden values. As such, the test only verifies that the performance of the replay gain analyser has not changed. A better test would be to compare the computed value with an independently obtain theorectical value. This is possible by

Sorry about the duplicate posts from Earl Chew. He's resent because the first v3 patch got caught in the moderation queue, and I didn't notice when I released the messages. Not his fault. :-) -r

Good thing you've got time off work so you can get work done! Shall I harass you about your patch queue at LCA? -r

Erik, I suspect /bin/sh being dash is what is causing the problem. I will rework the syntax.

Hi all, In the last couple of months, there have been two proposed patches for the regain play analysis code. The first by Nathan Rennie-Waldock: http://lists.xiph.org/pipermail/flac-dev/2011-December/003070.html simply adds some more higher sample rates. The second by Earl Chew: http://lists.xiph.org/pipermail/flac-dev/2012-January/003067.html is more comprehensive. Neither of the

Josh, Sure. I can try. Would you give me a more detailed description of the requirement ? What exactly does "general MM:SS handling" mean ?

Josh, I see my name is mentioned in passing ;-) I submitted that patch because I thought it preferable to keep the test harness running. Backing this change out would also entail changing metaflac_test.sh accordingly, which at the time, I was hesitant to do. At the time I figured that at some point metaflac_test.sh was passing, so the code should probably allow it to pass. I'm ok either

Erik, I'll resync and have another look.

David Robinson kindly provided me the filter values for 28 kHz sampling rate and I have inserted the filter values into the gain analysis table. Following the previous patch: http://lists.xiph.org/pipermail/flac-dev/2012-January/003067.html extend the supported sample rates to cover all rates supported in Foobar2000: 192000 = 4 x 48000 176400 = 4 x 44100 144000 = 4 x 36000 128000 = 4 x 32000

You change the volume of the audio tracks, so isn't this lossy or does the actual volume

When reading the INDEX from the cue sheet, the format MM:SS:FF format is disallowed if the sample frequency is not a multiple of 75 because the index would only be approximate. However, 00:00:00 is _exact_ because it denotes the start of the track, so allow it as a special case. This allows metaflac_test.sh to pass. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Ah, I don't remember but it might have been a negative test that was supposed to give an error when used with the wrong sample rate. Anyway, could you do another patch that updates to general MM:SS handling? >________________________________ > From: Earl Chew <earl_chew at yahoo.com> >To: Josh Coalson <xflac at yahoo.com>; "flac-dev at xiph.org" <flac-dev

How are people doing gain control, out of curiosity? I know boxes exist (anyone have names and mfrs?) that ride the gain for big radio stations, ensuring that there is no distortion and raising the volume of songs recorded at a lower volume. I'd probably buy one if I knew what to buy. ------ Dave Hayes - Consultant - Altadena CA, USA - dave@jetcafe.org Now Playing at:
