About AFsp:
A collection of audio utility programs and C library routines for reading and writing audio files.
This BeOS "port" of AFsp is based on a simple rework of
the original source. AFsp is copyrighted by Peter Kabal,
a professor in the Department of Electrical & Computer
Engineering at McGill University.
Here's a summary list of programs offered in AFsp:
InfoAudio -
display information about an audio file.
CompAudio -
compare audio files, producing statistics and signal-to-noise
ratio figures.
CopyAudio -
copy audio files. This program combines samples from input
audio files (an arbitrary linear combination) and writes them
to the output file in a user selectable format. One application
is to provide format conversion for an audio file; another is to
combine samples from multi-channel files.
FiltAudio -
filter audio files. This program filters an audio file with an
FIR, IIR or all-pole filter.
GenNoise -
generate noise. This program generates an audio file
containing Gaussian white noise.
GenTone -
generate a tone. This program generates an audio file
containing samples from a sinusoid.
LPanal -
demonstration program to do LPC analysis on a speech file.
LPsyn -
demonstation program to do LPC synthesis from a residual
file.
ResampAudio -
resample data from an audio file. This process involves
interpolating between the samples in the original file to
create a new sequence of samples with a new spacing
(sampling rate).
The package includes the filters from the ITU-T Software
Tool Library (G.191) in a form that can be used directly
with the FiltAudio program.
The following file formats are supported for reading.
- Headerless audio files
- AU audio files
- RIFF WAVE files
- AIFF/AIFF-C audio files
- NIST SPHERE audio files
- IRCAM sound files
- INRS-Telecom audio files
- ESPS sampled data feature files
- Text audio files (NATO/ESPRIT CD-ROM format)
The following file formats are supported for writing.
- Headerless audio files (including text files)
- AU audio files
- RIFF WAVE files
- AIFF-C audio files
Source note: I successfully compiled AFsp on BeOS R5/x86. The source package *should* build on earlier releases as well as the PPC platform, hopefully without need of further tweaking.
