fink

Read signals from a file at k-rate.

Syntax

fink ifilename, iskipframes, iformat, kin1 [, kin2] [, kin3] [,...]

Initialization

ifilename -- input file name (can be a string or a handle number generated by fiopen)

iskipframes -- number of frames to skip at the start (every frame contains a sample of each channel)

iformat -- a number specifying the input file format. If a header is found, this argument is ignored.

• 0 - 32 bit floating points without header
• 1 - 16 bit integers without header

Performance

fink is the same as fin but operates at k-rate.

Note

Please note that since this opcode generates its output using input parameters (on the right side of the opcode), these variables must be initialized before use, otherwise a 'used before defined' error will occur. You can use the init opcode for this.

Examples

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

<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 fink.wav -W ;;; for file output any platform
</CsOptions> 
<CsInstruments> 

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

gihand fiopen "test.txt", 1
