- Short: MPEG audio decoder w/ source; supports layer I-III
- Author: kai_rode@pluribus.wupper.de
- Uploader: kai_rode@pluribus.wupper.de
- Type: mus/misc
-
- This is a no-changes port of the Fraunhofer Institute MPEG audio decoder,
- Version 4.1. It supports compression layers 1-3.
-
- The MPEG-audio compression standard provides exceptional compression
- ratios for audio samples of 32 KHz (DAT-LP), 44.1 KHz (CD) and 48 KHz
- (DAT-SP). The only disadvantage of MPEG-compression is the sloooow
- speed. This decoder takes 1:28 minutes on a A4000/040/28(WARP) to
- decompress the included example which is a 15-second mono sample in
- CD-Quality (44.1 KHz).
-
- Included is the full sourcecode, three executables (68000/FFP, 68020/IEEE
- and 68040/internal FPU) and an example file compressed using layer 2
- compression.
-
- Suggested way for playing MPEG-samples on the amiga:
-
- Decoding using this program:
-
- - Start decode0x0
- - Type the name of the compressed sample (eg. foobar.mp2)
- - Type the name for the decompressed sample (foobar.sw)
- - Type "n" twice
-
- Converting using AmiSOX:
-
- - Type "sox -r 44100 foobar.sw foobar.wav"
-
- Playing using Play16:
-
- - Type "play16 foobar.wav fast hifi"
-
- This way, you can listen to the samples in 14-bit-quality, which you cant if
- you convert to 8SVX.

-
- This is the adress of the Internet Underground Music Archive, which contains
- many freely distributable pieces of high quality music. The example file
- is also from there.
