Function Documentation

void AesGetDefaultParam

(

AesParam *

p

)

Get default parameters.

Parameters:

[in]

param

pointer to Aes parameters

Caller should set the sampling rate and frame size.

Aes* AesNew

(

AesParam *

param

)

Create a new AES object.

Parameters:

[in]

param

AES parameters

void AesProc	(	Aes *	p,
		float *	ref,
		float *	rec
	)

Process samples.

Parameters:

[in]	p	pointer to Aes object
[in]	ref	reference signal
[in,out]	rec	recorded signal input, echo suppressed output

void AesSetLatency	(	Aes *	p,
		int	latency
	)

Set latency.

Parameters:

[in]	p	pointer to Aes object
[in]	latency	estimated I/O latency in samples

The Aes algorithm will compensate for measured latency by internally delaying the reference signal.

void AesSetMatlabDump	(	Aes *	p,
		int	dumpData,
		char *	path
	)

Set Matlab dump file.

Parameters:

[in]	p	pointer to Aes object
[in]	dumpData	T/F enable matlab data dump
[in]	path	pathname of dump file

Enable dumping of internal signal data for later plotting in matlab.
