I've been using mpc (1.9.7) and recently switched to the faster 0.90o
The cd was "ripped" to *.wav files with EAC (v09preb7) no normalizing
the wav file has audible distortion clicks/clips (not read errors)
When loaded into Cool Edit ,i can see that the wav file is to loud (the peeks are clipped, see picture )
I get this error when trying to encode with 0.90o
MP+/MPC Encoder 0.90o --ALPHA VERSION-- © 1999-2001 Buschmann/Klemm/Piecha
StreamVersion 7, Profile 'Standard'
maximum bandwidth: 22050 Hz
MS: enhanced
Ltq: ank (offset: 0.0 dB)
WARNING: There occured 18 internal clippings
Re-encode with '-scale 0.884'
or normalize input file with 88.4%
---------------------------------------------------------------------
And in Frank Klemm's FAQ it says;
Q34: I got the following message while encoding:
WARNING: There occured 31 internal clippings!
Re-encode with "-scale 0.923"
or normalize input file with 92.3%
A34: This is a bug in the StreamVersion 4...7 file format. The audio signal
is so high that subband samples above >47220 are generated. There are
two possiblities:
- clip the subband samples to +/- 47220
- use scale factor outside 0...63, which are mostly possible by
relative addressing (instead of the 6 bit absolute addressing).
The first solution is compatible with all decoders, but generates
higher coding errors, the second can only be played by Klemm based
decoders (which supports scale from -4...127)
----------------------------------------------------------------------
I would like to normalize wav file to 88.4% and with some ? magic plug-in? reconstruct the peeks
I read a article about restoration of old BBC TV programs , the audio engineer said noise reduction & distortion
removal were fairy easy with their digital equipment
My Questions are;
1.What would you do with this type of song (--scale in the encoder or replay gain? )
2. Are their any programs/plug-in to reconstruct the peeks/distortion removal ?
