wave Waveform of the LFO. (0 = triangle, 1 = wave, default 1)
delay Number of milliseconds the input is delayed before it is played back.
(range: 0 to 20, default 0)
phase Phase differential between left and right LFOs. (range: 0 to 4, default
2)
sound_effect_echo(snd,wetdry,feedback,leftdelay,rightdelay,
pandelay) Sets the parameters for the echo effect for the indicated sound.
The following parameters can be set:
wetdry Ratio of wet (processed) signal to dry (unprocessed) signal. (range: 0
to 100, default 50)
feedback Percentage fed back into input (range: 0 to 100, default 0)
leftdelay Delay for left channel, in milliseconds. (range: 1 to 2000, default
333)
rightdelay Delay for right channel, in milliseconds. (range: 1 to 2000,
default 333)
pandelay Whether to swap left and right delays with each successive echo. (0
= don't swap, 1 = swap, default 0)
sound_effect_flanger(snd,wetdry,depth,feedback,frequency,wa
ve,delay,phase) Sets the parameters for the flanger effect for the indicated
sound. The following parameters can be set:
wetdry Ratio of wet (processed) signal to dry (unprocessed) signal. (range: 0
to 100, default 50)
depth Percentage by which the delay time is modulated by the low-frequency
oscillator, in hundredths of a percentage point. (range: 0 to 100, default 25)
feedback Percentage of output signal to feed back into the effect's input.
(range: -99 to 99, default 0)
frequency Frequency of the LFO. (range: 0 to 10, default 0)
wave Waveform of the LFO. (0 = triangle, 1 = wave, default 1)
delay Number of milliseconds the input is delayed before it is played back.
(range: 0 to 20, default 0)
phase Phase differential between left and right LFOs. (range: 0 to 4, default
2)
sound_effect_gargle(snd,rate,wave) Sets the parameters for the
gargle effect for the indicated sound. The following parameters can be set:
rate Rate of modulation, in Hertz. (range: 1 to 1000, default 1)
wave Shape of the modulation wave. (0 = triangle, 1 = square, default 0)
