     "Libsndfile is a C library for reading and writing files containing
sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through
one standard library interface.

It was designed to handle both little-endian (such as WAV) and
big-endian (such as AIFF) data, and to compile and run correctly on
little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well
as big-endian processor systems such as Motorola 68k, Power PC, MIPS and
SPARC.  Hopefully the design of the library will also make it easy to extend
for reading and writing new sound file formats.")

    (description
     "Secret Rabbit Code (aka. libsamplerate) is a Sample Rate Converter for
audio.  One example of where such a thing would be useful is converting audio
from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT
players.

SRC is capable of arbitrary and time varying conversions; from downsampling by
a factor of 256 to upsampling by the same factor.  Arbitrary in this case means
that the ratio of input and output sample rates can be an irrational
number.  The conversion ratio can also vary with time for speeding up and
slowing down effects.

SRC provides a small set of converters to allow quality to be traded off
against computation cost.  The current best converter provides a
signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of
the theoretical best bandwidth for a given pair of input and output sample
rates.")

origins: computer fans, offices, crowds, airplanes, cars, trains,
construction, and more.

Mild background noise is always suppressed, loud sounds, like
clicking of mechanical keyboard, are suppressed while there is no voice
however they are only reduced in volume when voice is present.

The plug-in is made to work with 1 or 2 channels (LADSPA plugin),
16 bit, 48000 Hz audio input.")
