Full Version: frank klemm's mppenc doesn't flex so low, why?

the old mppenc 1.79c flexes very low sometimes (for example: portishead - sour times 96kb/s avg. or tricky - hell is round the corner 88kb/s avg.). the bitrate stays much higher using mppenc 0.90s (sour times 144kb/s avg. ). i wonder why there is this huge differenc, as bouth encoders use the same psychoacoustics.

You are mistaken with Sour Times (from the album Dummy). I checked using 1.7.9c and 0.90s both with standard profile. The MPC files both have an avg. bitrate of 144.

if the file is a mono file, the bitrate will be a lot less...

perhaps somehow the other test file got made into mono?
ilikedirtthe2nd
your right, i was mistaken. i checked it and bouth files result in an avg. bitrage of 144. just wondered, why the file i encoded some time ago was so much lower.

don't think the file got into mono as i usually ripped it and did not use any commline switches.

ps: tricky - hell is round the courner still results in 88kb/s with bouth encoders.

its not the bitrate that really matters though... as long as it sounds good...

My guess is that the Tricky song is mono. I have some jazz CD's from the fifties/sixties and they are also mono. Encoded with MPC standard they also have a bitrate of 85-90.

Nope, I have an older copy of Portishead done with Buschel's encoder, back before they implemented the standard and xtreme data saved into tags, and mine displays as 98Kbps average. I have, um... "lost" the CD and can't re-encode to see what I'd get now. The file is most certainly stereo. My guess would be vastly changed defaults since the file was encoded, though I do everything at xtreme these days just for fun.
