(8.D.2.5) SourceFract32Properties

Overview

Source buffer holding 1 wire of fract32 data

Discussion

The source module has an internal buffer holding 1 output wire's worth of fract32 data. The module continuously copies the data from the internal value buffer to the output wire. Since this is a source module, you must specify the number of channels, blockSize, and sample rate of the output pin

Additionally, this module makes the wire information available as internal variables. Block size, channel number, sample rate and signal complexity can be accessed in MATLAB code, source code, or in a layout using the ParamGet module.

MATLAB Usage

File Name: source_fract32_properties_module.m

M=source_fract32_properties_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE, ISCOMPLEX) Creates a source module that allows you to inject fract32 data into the audio processing layout. Arguments: NAME - name of the module. NUMCHANNELS - number of interleaved channels in each output pin. By default, NUMCHANNELS = 1; BLOCKSIZE - number of samples per output channel. By default, BLOCKSIZE = 32. SAMPLERATE - sample rate of the output signal, in Hz. By default, SAMPLERATE = 48000. ISCOMPLEX - Boolean indicating whether the output holds complex data. By default, ISCOMPLEX=0.
