multitap

multitap — Multitap delay line implementation.

Description

Multitap delay line implementation.

Syntax

ares multitap asig [, itime1, igain1] [, itime2, igain2] [...]

Initialization

The arguments itime and igain set the position and gain of each tap.

The delay line is fed by asig.

Examples

Here is an example of the multitap opcode. It uses the file multitap.csd

Example 516. Example of the multitap opcode.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac   ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o multitap.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100
ksmps = 32
nchnls = 2
0dbfs  = 1

ga1 init 0

instr 1

asig diskin2 "beats.wav", 1,0
     outs asig, asig
   
ga1  = ga1+asig
endin

instr 2

asig multitap ga1, 1.2, .5, 1.4, .2
     outs     asig, asig
	
ga1  = 0
endin

</CsInstruments>
<CsScore>

i 1 .5 .2	; short sound
i 2  0  3	; echoes
e
</CsScore>
</CsoundSynthesizer>


This results in two delays, one with length of 1.2 and gain of .5, and one with length of 1.4 and gain of .2.
