e. Filter(<which output>,<which filter>) = Highshelf,<filter frequency>,<filter
gain>;
Filter(<which output>,<which filter>) = Lowshelf,<filter frequency>,<filter
gain>;
The first form defines a high shelf filter at the specified frequency and the
specified gain. <filter frequency> must be an integer between 20 and
20000Hz. <fitler gain> must be between -40.0 and 15.0 in dB. For example,
Filter(1,2) = Highshelf,4000,3.0;
// highshelf at 4kHz with 3dB gain
f. Filter(<which output>,<which filter>) = Bandpass,<filter frequency>,<filter
gain>,<filter bandwidth>;
Defines a bandpass filter. <filter frequency> must be an integer between 20
and 20000Hz. <filter gain> must be between -40.0 and 15.0 dB. <filter
bandwidth> must be between 0.05 and 4.0 in octaves. For example,
Filter(1,2) = Bandpass,1000,-6.0,1.2;
// bandpass at 1kHz,
// -6dB gain and
// 1.2 octave wide.
g. Fade to Unity in <fade time expression>;
Fade the mixer matrix to a unity matrix in the given fade time. <fade time
expression> is an arithmetic expression to be evaluated to an integral number
of frames assuming 30 frames per second. For examples,
Fade to Unity in 30;
// fade to unity matrix in 1 second
Fade to Unity in (30 + random(60,120));
// fade to unity matrix
// fade time is between 3 to 5 seconds
h. Fade to Zero in <fade time expression>;
Fade all mixer matrix to a zero matrix, i.e. all off, in the given fade time.
<fade time expression> is an arithmetic expression to be evaluated to an
integral number of frames assuming 30 frames per second. For example,
Fade to Zero in 90;
// everything off in 3 seconds
i. Fade <input number> to <output gain list> in <fade time expression>;
Fade the given input to the list of outputs at the given gain. <output gain list>
is one or more of (<output number>,<gain expression>) separated by commas.
<output number> specifies the output and <gain expression> is an arithmetic
expression to be evaluated to a floating point number representing the crosspoint gain in dB. The cross-point gain must be less than or equal to zero dB.
<fade time expression> is an arithmetic expression to be evaluated to an
integral number of frames assuming 30 frames per second. For example,
Fade 2 to (1,0.0),(2,-64.0) in 90;
// fade input 2 to output 1 full
