SampleAndHoldInt32

Discussion

An audio rate sample and hold module for use with the Audio Engine. The module has two input pins: trigger and data. The module samples the input data whenever trigger != 0. The module is designed to work with multichannel data. There are two operating modes. If the trigger pin has a single channel, then the trigger is applied to all of the interleaved data channels. Otherwise, if the trigger has the same number of channels as the data, then a separate trigger is applied to each channel.

Internally, the module stores the sampled data within the value array. This array has 1 sample per input channel.

Type Definition

typedef struct _ModuleSampleAndHoldInt32
{
ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
INT32* value;                                 // Holds the last data value which was sampled.  This is an array so that multiple channels can be supported.
} ModuleSampleAndHoldInt32Class;
