Question about MAD on ARM
by hover0815＠yahoo.com.tw 25 Sep '03

25 Sep '03

Hi, I have several questions about MAD plays mp3 on ARM-based platform. When I play mp3 with MAD on ARM, there is an unusual phenomenon. 1. While playing a mp3 file which frequency is lower than 44100 hz, the music sounds like downsampled. Which means the sound is faster such that the time of play is fewer than original. 2. When applying the attenuation command (ex, --attenuate=10), some mp3 files will play intermittently. It seems CPU cannot support such high calculation. (CPU clock rate is 96khz) There are additional 2*32*36 multiplication per frame. Can MAD be simplified so that it can play mp3 more smoothly? 3. Why do some files play intermittently, and some don't? I tried several files, and still can not get its rule. bit rate freq. channel mode result 112k 44100 JS ok 128k 32000 JS X 128k 44100 S ok 192k 44100 JS ok 192k 44100 S X It seems irrelative to bit rate, sample frequency or channel mode. What's the rule? Can someone help me? Thank you --------------------------------- 每天都 Yahoo!奇摩海的顏色、風的氣息、愛你的溫度，盡在信紙底圖信紙底圖

sox and dithering
by DervishD 21 Aug '03

21 Aug '03

Hi all :) I've noticed that the cdda output of 'sox' from a mp3 file is *very* different from the output of madplay, given of course the same mp3 file. In fact the diference is even noticeable in the waveform. I wonder if the cause is that sox does not perform dithering, but disabling dithering in madplay doesn't solve the problem. Maybe sox is just truncating the samples? I'm not asking to the sox author yet because this can be a MAD issue (configuration options of the library generating different output but not lesser quality, for example). Thanks a lot in advance. BTW, I use madplay as mp3 player, because I think that it is what a player *must* be: simple, easy, fast, etc... Great, Rob, great.

Madplay capture output to file - how to?
by Gurpal S. Bhachu 20 Aug '03

20 Aug '03

Hi, I wish to capture the output of madplay to an external file eg: $ madplay abc.mp3 -o abc.wav > abc.txt It seems that abc.txt contains nothing! Is there some weird non standard out thing happening here? Please could someone advise how to do this... Many thanks, Gurpal

I will look for updates but I downloaded the latest from sourceforge. Thanks!

MAD play will not compile
by dj nano 10 Jul '03

10 Jul '03

Hello, I've searched the archives and no one else seems to have this problem: When I attempt to compile the 4th of the tarballs, madplay-0.15.0b it finds errors in the 'libid3' links. Libid3 already compiled successfully. This occurs even when I use the syntax "./configure --libdir=/usr/local/lib", (the configure completes). Is this error somehow related to all the info in the archives about MAD not handling ID3 tagging properly? Is there a workaround? Unlike most I don't really care if the ID info shows up; I'm looking for better playback. I use Red Hat 9 on a dual athlon 1900+ with an m-Audio delta 1010 (run by ALSA). Can anyone advise? error out put: make all-recursive make[1]: Entering directory `/home/morpha/MAD/madplay-0.15.0b' Making all in intl make[2]: Entering directory `/home/morpha/MAD/madplay-0.15.0b/intl' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/home/morpha/MAD/madplay-0.15.0b/intl' Making all in po make[2]: Entering directory `/home/morpha/MAD/madplay-0.15.0b/po' make[2]: Nothing to be done for `all'. make[2]: Leaving directory `/home/morpha/MAD/madplay-0.15.0b/po' make[2]: Entering directory `/home/morpha/MAD/madplay-0.15.0b' /bin/sh ./libtool --mode=link gcc -Wall -march=i486 -g -O2 -o madplay madplay.o getopt.o getopt1.o version.o resample.o filter.o xing.o player.o audio.o audio_aiff.o audio_cdda.o audio_hex.o audio_null.o audio_raw.o audio_snd.o audio_wave.o audio_esd.o audio_oss.o -lesd -lmad -lid3tag -lm gcc -Wall -march=i486 -g -O2 -o madplay madplay.o getopt.o getopt1.o version.o resample.o filter.o xing.o player.o audio.o audio_aiff.o audio_cdda.o audio_hex.o audio_null.o audio_raw.o audio_snd.o audio_wave.o audio_esd.o audio_oss.o -lesd /usr/local/lib/libmad.a /usr/local/lib/libid3tag.a -lm resample.o(.text+0x29): In function `resample_init': /home/morpha/MAD/madplay-0.15.0b/resample.c:46: undefined reference to `mad_f_div' player.o(.text+0xb56): In function `show_id3': /home/morpha/MAD/madplay-0.15.0b/player.c:630: undefined reference to `id3_frame_field' player.o(.text+0xc11):/home/morpha/MAD/madplay-0.15.0b/player.c:674: undefined reference to `id3_frame_field' player.o(.text+0xc36):/home/morpha/MAD/madplay-0.15.0b/player.c:680: undefined reference to `id3_frame_field' player.o(.text+0x10dd): In function `process_id3': /home/morpha/MAD/madplay-0.15.0b/player.c:801: undefined reference to `id3_frame_field' player.o(.text+0x112e):/home/morpha/MAD/madplay-0.15.0b/player.c:846: undefined reference to `id3_frame_field' player.o(.text+0x1137):/home/morpha/MAD/madplay-0.15.0b/player.c:846: undefined reference to `id3_field_getlatin1' player.o(.text+0x114a):/home/morpha/MAD/madplay-0.15.0b/player.c:847: undefined reference to `id3_frame_field' /usr/local/lib/libid3tag.a(util.o)(.text+0x105): In function `id3_util_compress': /home/morpha/MAD/mad-0.14.2b/libid3tag/util.c:116: undefined reference to `compress2' /usr/local/lib/libid3tag.a(util.o)(.text+0x160): In function `id3_util_decompress': /home/morpha/MAD/mad-0.14.2b/libid3tag/util.c:142: undefined reference to `uncompress' collect2: ld returned 1 exit status make[2]: *** [madplay] Error 1 make[2]: Leaving directory `/home/morpha/MAD/madplay-0.15.0b' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/morpha/MAD/madplay-0.15.0b' make: *** [all] Error 2

What are the interactive keyboard controls for madplay? Such as for pause, stop, increase/decrease volume, etc...I've been looking in all the documentation and can't seem to find it...maybe my eyes are just tired. Thank you. ********************************* * naomi(a)winlab.rutgers.edu * *********************************
