mp3gain vs madplay
by Bruce Fitzsimons 15 Sep '04

Peoples, I'm about to launch into a debugging session to see why mp3gain (http://mp3gain.sourceforge.net/ ) and madplay 0.15.1b don't seem to be playing together (no pun intended). I thought I'd ask if anyone has used the two together yet, or if there is another linux-based replaygain processor (for adding replaygain to existing mp3s) that is more reliable. map3gain does appear to be adding a tag, as it finds it again if rerun over the same file. "# mp3gain /tmp/Abracadabra.mp3 /tmp/Abracadabra.mp3 Recommended "Track" dB change: -1.690000 Recommended "Track" mp3 gain change: -1 Max PCM sample at current gain: 28533.063680 Max mp3 global gain field: 180 Min mp3 global gain field: 116 Recommended "Album" dB change for all files: -7.490000 Recommended "Album" mp3 gain change for all files: -5" madplay doesn't appear to find it: "# madplay -G -Tv /tmp/Abracadabra.mp3 MPEG Audio Decoder 0.15.1 (beta) - Copyright (C) 2000-2004 Robert Leslie et al. Title: Abracadabra Artist: The Steve Miller Band Album: Golds Greatest Hits Track: 11 Year: 1982 Genre: Vocal Encoder Version: LAME 3.92 VBR Method: constant Bitrate: 255+ kbps Stereo Mode: normal Preset: none Unwise Settings: no Encoding Flags: Lowpass Filter: 19500 Hz ATH Type: 2 Noise Shaping: 1 Surround: none Start Delay: 576 samples End Padding: 1503 samples Source Rate: 44.1 kHz Music Length: 9948263 bytes Audio Frames: 11900" (note the missing "Replay Gain" printout I expect after reading the source) I'd hasten to add that I suspect mp3gain of doing something wrong, not madplay. I'm guessing the tag is wrong or in the wrong place. Any info would be appreciated, otherwise I'll report my findings to the list when I discover the root cause. /Bruce

Hi all, I am new to audio and video decoder, hence would appreciate some help in the beginning. I have an mpg file which has both and audio and video stream encoded. I use libmpeg2 to decode the video and display it on the monitor. I also use libmad to play the audio. when i decode the mpg file i store audio part of the mpg file in a separate file (for ex: audio.ma2). After mpg file decoding is over, i run madplay with the following options. madplay -v /root/audio.ma2 I see the following error message on the screen. MPEG Audio Decoder 0.15.2 (beta) - Copyright Â© 2000-2004 Robert Leslie et al. error: frame 0: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 3: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 6: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 9: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 12: CRC check failed 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 14: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 17: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 20: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 23: CRC check failed 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 25: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 28: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 31: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 34: lost synchronization 00:00:00 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 36: lost synchronization 00:00:01 Layer II, 224 kbps, 44100 Hz, stereo, CRC error: frame 39: lost synchronization 00:00:01 Layer II, 224 kbps, 44100 Hz, stereo, CRC could anybody please tell me what could be the problem? regards, -onup Yahoo!
