Hi,

I encode my Music-Cd's with mppenc 1.14 beta (--quality 10 --xlevel). On some of the CD's (1 of 12) mppenc reports that the encoder does clipping and I have to use the --scale method to prevent that. I played a little bit around with this switch and mppenc reports to use replaygain tool to determine the exact attentuation to avaoid clipping. But I dont now how to use that tool.

Can somebody help me ? Thanx ...

P.S: Sorry for my english.

The key to the answer is that there are 2 kinds of clipping possibilities .
The above is the so called internal clipping during encoding of mpc. The --xlevel switch helps to minimizes this problem but in rare cases you need to scale down the input. mppenc gives you the suggested scale value.
BTW this is addressed and will be solved in MPC Stream Version 8

This is about clipping during decoding / playback. Replaygain is also used to adjust the volume so the perceived loudness of albums or tracks will not differ so much.

And uh, you should really try a more realistic --quality setting (but there are enough threads about that already )

Uh?! I love overkills, but this seems to be a bit exaggerated even for me...

Don't worry too much about clipping during encoding, if you use --xlevel. It's not so severe.

About ReplayGain, read this thread, and ask questions here if you didn't understand something.

Hi,

Yet I know my "mistake". If I encode without the xlevel switch, mppenc gives me an value for scale. I never tried out without this switch.

@GeSomeone: Thank you, for your explanation. I use so high Bitrates just for Archival Purposes and to have enough "Room" for reencoding (for Portable MP3 Player, ...). My Computer acts as an Music-Jukebox and here I use -q6 switch.

@Citay: One of the first Threads I readed here.

You should continue to use the --xlevel switch. Usually, only a handful clippings still occur with this switch, whereas without it, hundred internal clippings are sadly not uncommon with today's music.

Hi CiTay,

My English as you know isnt very good. I Meant that I just leave the swítch out to find the scale value and encode it with xlevel and scale again ... And Yes I know If I use xlevel I don't need to downscale so much as without this Option. So why I didn't get the correct scale value with xlevel ? In some songs I have 50-100 clippings even with this Option.

hehe, -q10.

Hi torok,

Until Mr. Klemm has corrected the Bug if -q 11 is used.

If you use --xlevel, don't scale at all. The remaining clipping will most likely be overshadowed by the bad mastering of such songs.

Hi,

O.K.
