Hi ALL,

MPC has two recommended low bitrate presets:

--telephone lowest quality, (typ. 32... 48 kbps) [SoundExpert FBR = 59.9 kbit/s]
--thumb low quality/internet, (typ. 58... 86 kbps) [SoundExpert FBR = 82.4 kbit/s]

I have two questions in concern:

1. Will it be reasonable to add the codec to SoundExpert rating system taking into account that MPC is intended mostly for higher bitrates.

2. In case of positive answer to the first question what should be better - to add it with those presets or to choose quality parameter to match desired output bitrate (48, 64, 96) exactly?

Hope to hear your thoughts.

MPC is not tuned enough right now for such low bitrates. Gotta wait to SV8.

As mentioned before, I liked the sound of --thumb with the c't reference.wav, so in my opinion it would make sense, although the bitrate was higher than AACEnc -radio for example.



That's the biggest difficulty for a fair comparison, because Musepack uses a way too high bitrate on samples with mostly tonal content. If you force it to rather use the expected bitrate (like you always did for other codecs yet), it will sound terrible. If you let it double the expected bitrate (e.g. with the er-hu sample), it will sound fine, but other codecs will sound fine with ~128 kbps, too...

Well, it seems that time hasn't come for MPC at SoundExpert yet.
