abs — Returns an absolute value.


Returns the absolute value of x.


abs(x) (no rate
abs(k/i[]) (k- or i-arrays )

where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.


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

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

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

sr = 44100
ksmps = 32
nchnls = 2

instr 1
ix = p4
iabs = abs(ix)
print iabs



i 1 0 1 0
i 1 + 1 -.15
i 1 + 1 -13


Its output should include lines like:

instr 1:  iabs = 0.000
instr 1:  iabs = 0.150
instr 1:  iabs = 13.000
