@title{(record-buf bufnum offset reclevel prelevel run loop trigger inputs)}
|
|
|
|
Records input into a Buffer.
|
|
|
|
If recLevel is 1.0 and preLevel is 0.0 then the new input
|
|
overwrites the old data. If they are both 1.0 then the new data is
|
|
added to the existing data. (Any other settings are also valid.)
|
|
|
|
bufnum - the index of the buffer to use
|
|
offset - an offset into the buffer in samples, default 0
|
|
recLevel - value to multiply by input before mixing with
|
|
existing data. Default is 1.0.
|
|
preLevel - value to multiply to existing data in buffer before
|
|
mixing with input. Default is 0.0.
|
|
run - If zero, then recording stops, otherwise recording
|
|
proceeds. Default is 1.
|
|
loop - If zero then don't loop, otherwise do. This is
|
|
modulate-able. Default is 1.
|
|
trigger - a trigger causes a jump to the start of the Buffer.
|
|
A trigger occurs when a signal changes from <=0 to >0.
|
|
inputArray - an Array of input channels
