GOGO-no-coda ver. 2.36 updated Aug. 11, 2000 * ABSTRACT This software is a mp3 encoder based on LAME3.29 ( including a part of LAME3.5x ), which is optimized by PEN@MarineCat, Keiichi SAKAI, URURI, kei and shigeo, modified by Noisyu for BeOS Intel, modified by Samuel Audet for OS/2. GOGO can encode about TWICE as fast as original LAME can on K6-2 315MHz, and its quality is the about same as (old) LAME's. GOGO makes use of MMX, (Enhanced) 3D Now! and SSE if your system supports these units. Remark: Linux and FreeBSD don't support SSE formally. * CONTENTS *(1) NEWS *(2) HOW TO USE *(3) EXAMPLES *(4) HOW TO MAKE *(5) NEWER VERSIONS *(6) LICENSE *(7) NAMING *(8) FAQ *(9) APPENDIX (1) NEWS optimize for SSE + SMP on Linux and Windows. decrease pre-echo in low-bitrate encoding. support messages in Japanese SJIS/EUC, English, German and Spanish. * new options -lang {sjis,eucjp,eng,ger,esp} print messages in Japanese SJIS/EUC, English, German and Spanish.

(dflt stereo) -8bit : supporse 8bit-PCM. (dflt 16bit) -bswap : low, high byte swapping for 16bit-PCM. -s kHz : input wav sampling frequency. (dflt 44.1kHz) -delete : delete wav-file after encoding -i : verify and overwrite -o path : output mp3-file into path -riff {wave, rmp} : wrapping format wave:RIFF/WAVE rmp:RIFF/RMP (3) EXAMPLES % gogo sample.wav : joint-stereo 128kbps output file is sample.mp3. % gogo sample.wav -m s -b 160 -nopsy : stereo 160kpbs disable psycho-acoustics % cat sample.wav|gogo stdin a.mp3 -b 160 : joint-stereo 160kbps stdin-mode % gogo sample.raw -offset 0 : input PCM is no header, stereo 16bit 44.1kHz. (4) HOW TO MAKE You need NASM-0.98 (http://www.web-sites.co.uk/nasm/). This source includes Japanese characters in comments, so please delete or translate them. NO_KANJI is disused. cf. -lang option Otherwise we define JAPANESE_SPC in common.h. This is for dealing with path including Japanese, but undefine it if you want. Set USE_E3DN=yes if you want to use enhanced 3D Now! for Athlon. ( See Appendix ) But if so, you must patch NASM to assemble those mnemonics, or get http://www.kurims.kyoto-u.ac.jp/~shigeo/soft/3dnow18.lzh and %mkdir mmx;cd mmx;lha x 3dnow18.lzh;gcc -DONLY_E3DN *.c %mmx/a.out mdct3dn.nas %mv -f mdct3dn.asm mdct3dn.nas , and so on. For Linux, FreeBSD 3.x, OpenBSD, NetBSD % make If you want RPM, then type % rpm -ta --clean gogo235.tgz For Linux with libc6, FreeBSD-4.0R with linuxthreads or BeOS USE_MT=yes For FreeBSD 2.x read Makefile and change ASFLAGS. For Windows32 console copy win\*.* . set up as follow at custom-build-window for *.nas or open gogo.dsw (VC++6.0) [command] nasm -f win32 -DWIN32 $(InputName).nas [output] $(InputName).obj If you use Borland C++, then read Makefile and change ASFLAGS. Miquel made gogo_dll.bpr for gogo2.23, but it can't be applied to gogo2.24, so I don't include it, sorry. For BeOS % cd BeOS % MakeGOGO.sh To install, drag `gogo' into the link-folder provided. For OS/2 ( Mulithread is not supported ) make -f makefile.os2 (5) NEWER VERSIONS http://homepage1.nifty.com/herumi/gogo_e.html But we will stop developping gogo except fixing bugs. (6) LICENSE Copyright (C) 1999 PEN@MarineCat, shigeo Special Thanks to Keiichi SAKAI, URURI, Noisyu and Kei The patent laws about the ISO demonstration source are not applied in Japan now (99/11/11), so we release gogo with binary. But we will stop to do so according to circumstances. Gogo-no-coda is based on LAME 3.29 beta and distributed under the LGPL. The modifications are distributed under the LGPL. You can use gogo in your commercial program under the restrictions of the LGPL. You can include a compiled version of gogo library (Ex. gogo.dll) with a commercial program. In your program, you can't include any source code from gogo, with the exception of files whose only purpose is to describe the library interface (such as musenc.h, musui.c). Any modifications of gogo must be released under the LGPL. You must give prominent notice that your program is: A. using gogo including version B. gogo is under the LGPL C. provide a copy of the LGPL D. provide a copy of gogo source, or a pointer where the gogo source can be obtained (7) NAMMING `GOGO-no-coder' is a parody of `GOGO no cotya da', which means afternoon tea in Japan. Please feel free :-P. (8) FAQ Q. I can't make gogo bacause of the error messages about pswapd. A. Your NASM doesn't support Enhanced 3D Now!. Change E3DN=-DUSE_E3DN into #E3DN=-DUSE_E3DN in Makefile. See APPENDIX, too. Q. Can My system use (E)3D Now!/SSE/SMP? A. You can see the answer if you use gogo with -debug option. 3D Now! is available to WinChip2, K6-2, K6-III and Athlon on any OS. Enhanced 3D Now! is available to Athlon. SSE is available to PIII on WinNT/2000, Be and patched Linux. SMP is available on WinNT/2000, Linux, Be, Solaris and OS/2. Q. I want to encode many wave-files together. A. for example, on tcsh, % foreach i (*.wav) % gogo $i % end Q. Why don't you follow the latest LAME? A. It is impossible because gogo has been already quit different from LAME. Please use LAME if you want high-quality sound. Q. SMP performance is wrong in using stdin or Windows. A. On Windows, we program it against our will to support DLL. On Linux, you should use cdda2wav but cdparanoia because cdparanoia can't read and write simultaneously. (9) APPENDIX ( How to make NASM supporting Enhanced 3D Now! ) Append the following source to insns.dat and make, and you get NASM which can assemble Enhanced 3D Now!.
