delayw

delayw --  Writes the audio signal to a digital delay line.

Description

Writes the audio signal to a digital delay line.

Syntax

delayw asig

Performance

delayw writes asig into the delay area established by the preceding delayr unit. Viewed as a pair, these two units permit the formation of modified feedback loops, etc. However, there is a lower bound on the value of idlt, which must be at least 1 control period (or 1/kr).

Examples

Here is an example of the delayw opcode. It uses the files delayw.orc and delayw.sco.
