Description
PJMEDIA uses {{{resample-1.7.tar.gz}}} from [http://www-ccrma.stanford.edu/%7Ejos/resample/ Digital Audio Resampling Home Page].
Some excerpts from the original source codes:
{{{
HISTORY
The first version of this software was written by Julius O. Smith III
at CCRMA in
1981. It was called SRCONV and was written in SAIL for PDP-10
compatible machines. The algorithm was first published in
Smith, Julius O. and Phil Gossett. ``A Flexible Sampling-Rate
Conversion Method,'' Proceedings (2): 19.4.1-19.4.4, IEEE Conference
on Acoustics, Speech, and Signal Processing, San Diego, March 1984.
An expanded tutorial based on this paper is available at the Digital
Audio Resampling Home Page given above.
Circa 1988, the SRCONV program was translated from SAIL to C by
Christopher Lee Fraley working with Roger Dannenberg at CMU.
Since then, the C version has been maintained by jos.
Sndlib support was added 6/99 by John Gibson .
The resample program is free software distributed in accordance
with the Lesser GNU Public License (LGPL). There is NO warranty; not
even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
