Musepack (mpc) R8 (using SV8)

Re: Musepack (mpc) R8 (using SV8)

Replay Gain (SV7) now fixed, note this encoder will not write RG to sv8 files just yet.

OK, done. LMK if you don't receive it, it's about 9MB.

Please send me an SV7 file (the one you mentioned above would be great).

Re: Musepack (mpc) R8 (using SV8)

Can you give an example (in text) of a high RPG value?

Well, for instance, on one track that shows normally with the SV7 codec, "Album Gain" shows as -0.32 dB and "Track Gain" is -0.13 dB.

After installing SV8, the same track shows Album Gain of 166.76 dB and Track Gain of 166.27 dB.

"Album Peak" and "Track Peak" change also, but not to such an extreme: with the SV7 codec, they show as 0.991425 dB and 0.837708 dB, respectively. With SV8, the values are 0.704956 and 0.693512.

As I said, if I reconvert the original .flac with the new codec, it won't apply the RG tags at all, so I don't know what they would be in that case.

What the backwards compatible warning means is that if you have a player that uses a SV7 decoder it may not read the files properly.

Ok, well, I guess that's not why it's showing the insanely high ReplayGain tags on existing SV7 files.

Something else I noticed - the description of the RG fix implies that it simply was not showing (or attaching) the tags where the Gain value was 0 (zero). I don't believe that was the case. On albums where some mpc's displayed the tags and some didn't, the Album Gain was not zero in the tracks displaying the tags. AFAIK, that value should be constant for all tracks on the album. Now, with the new codec, the tracks which previously showed RG values have the high numbers, and the tracks that showed no value at all display 0.

Re: Musepack (mpc) R8 (using SV8)

Do I need to be running R13 for this? I installed it under 12.4 and it seems whacked out.

First of all, if I look at the ReplayGain tags on my existing .mpc's, both Album and Track Gain shows as incredibly high - upwards of 170dB for the most part. The Peak readings appear normal. OK, but as you said, "Please note SV8 is not likely to be backwards compatible with older decoders" - so maybe that's the issue, the codec has trouble reading the SV7 tags?

But worse, now I can't get any ReplayGain tags added at all to my .mpc's. If I "Convert to" .mpc from .flac, and tell it to include the RG, it doesn't - even in files that SV7 handled without issue (the tags exist in the source .flac's). Nor can I add the RG tags after the fact to the created .mpc.

Please note SV8 is not likely to be backwards compatible with older decoders, and as musepack.net says "We don't recommend that you start mass-encoding or converting SV7 files to SV8 just yet. If changes to the bitstream will have to be made, they may break compatibility with files created by the beta version. After the public beta testing period is finished (the period of time depends on the findings) and the final version is released, you could safely encode and convert."
