Function Documentation

◆ loadSourceConfigPreset()

void loadSourceConfigPreset	(	SOURCE_CONFIG_PRESETS	preset,
		_Atomic_FLOAT32	dirs_deg[MAX_NUM_INPUTS][2],
		_Atomic_INT32 *	nCH )

Returns the source directions for a specified source config preset.

The function also returns the number of source in the configuration Note: default uniformly distributed points are used to pad the dirs_deg matrix up to the MAX_NUM_INPUTS, if nCH is less than this. This can help avoid scenarios of many sources being panned in the same direction, or triangulations errors.

Parameters

[in]	preset	See SOURCE_CONFIG_PRESETS enum
[out]	dirs_deg	Source directions, [azimuth elevation] convention, in DEGREES;
[out]	nCH	(&) number of source directions in the configuration
