#include <n_libaudio.h>
void    n_alInit(N_ALGlobals *globals, ALSynConfig *c);

Arguments

• globals is the pointer to the N_ALGlobals structure
• c is the pointer to the Synthesis Driver configuration structure

Explanation
This function is available in the n_audio library. To use the n_audio library, you must first call this function to initialize a Synthesis driver with the configuration specified by c and to initialize the n_audio library global variables.

Configuration Structure
The configuration structure includes these members:

• maxVVoices is maximum number of virtual voices to allocate
• maxPVoices is the maximum number of physical voices to allocate
• maxUpdates is the maximum number of synthesizer updates to allocate
• maxFXBusses is the maximum number of effects busses to allocate
• dmaproc is the pointer to the Audio DMA callback initialization routine, which is called once for each physical voice and must return a pointer to the ALDMAproc that the voice will use when requesting a direct memory access (DMA) of audio samples
• heap is the pointer to an ALHeap structure that has been already been initialized by a call to the alHeapInit function
• outputRate is the desired hardware output rate (22k, 32k, or 44.1k)
• fxType is the desired effects type
• params is the pointer to the parameter list to use when constructing a custom effects chain.
