void ambi_bin_init	(	void *const	hAmbi,
		int	samplerate )

Initialises ambi_bin with default settings, and samplerate.

Warning: This should not be called while _process() is on-going!

Parameters

[in]	hAmbi	ambi_bin handle
[in]	samplerate	host samplerate.

Definition at line 148 of file ambi_bin.c.

◆ ambi_bin_initCodec()

void ambi_bin_initCodec ( void *const hAmbi )

Intialises the codec variables, based on current global/user parameters.

Note: This function is fully threadsafe. It can even be called periodically via a timer on one thread, while calling _process() on another thread. Since, if a set function is called (that warrants a re-init), then a flag is triggered internally and the next time this function is called, it will wait until the current process() function has completed before reinitialising the relevant parameters. If the _initCodec() takes longer than the time it takes for process() to be called again, then process() is simply bypassed until the codec is ready.; This function does nothing if no re-initialisations are required.

Parameters

[in] hAmbi ambi_bin handle

Definition at line 168 of file ambi_bin.c.

◆ ambi_bin_process()
