The following keywords specify the format of the output sound file:
byteordere
Desired endianness of output sample data. e may be one of big or little.
channelsn
Number of output channels. n is 1 for mono, and 2 for stereo files.
formatf
Audio format of output file. f has to be one of the currently supported formats: aiff (Audio
Interchange File Format), aifc (AIFF-C File Format), next (NeXT/Sun Format), wave (MS RIFF WAVE
Format), bicsf (Berkeley/IRCAM/CARL Sound File Format), avr (Audio Visual Research File Format),
iff (Amiga IFF/8SVX Sound File Format), or nist (NIST SPHERE File Format).
integerns
Produce integer samples. n specifies the width of individual samples in bits, s yields the
encoding and may be one of 2scomp (2's complement signed data), or unsigned (unsigned data). The
integer and float options (see below) are mutually exclusive.
floatm
Produce floating point samples with a maximum amplitude of m (usually 1.0). This options may not
be used together with option integer.
