Short: MPEGaudio encoder, speedup
Author: Henryk Richter
Uploader: tfa652@cks1.rz.uni-rostock.de
Type: mus/misc
Requires: a MC68EC030+ and FPU (accelerator and fastram recommended)
Looking at the sources of musicin I found out that there was a quite
slow FFT. Replacing that one with an own (between twice and three times
as fast) resulted in about 15% less encoding time.
The MusicIn program was originally ported by Michael Rausch and
optimized by Stephane Tavenard.
This archive contains Versions for 030+FPU, 040 and 060.
Last Changes: - added workaround for SAS-ASM Bug, now the FFT works as
expected and the sound quality is as good as it should be
- code cleanup, removed twice written routines to make
the program slightly shorter
