Function Documentation

ilbc_decode()

int ilbc_decode	(	ilbc_decode_state_t *	s,
		int16_t	amp[],
		const uint8_t	bytes[],
		int	len
	)

Decode a buffer of iLBC data to linear PCM.

Parameters

s	The iLBC deocde context.
amp	The audio sample buffer.
bytes	The excoded data.
len	The length of the encoded data, in bytes.

Returns

The number of samples returned.

ilbc_decode_init()

ilbc_decode_state_t* ilbc_decode_init	(	ilbc_decode_state_t *	s,
		int	mode,
		int	use_enhancer
	)

Initialise an iLBC decode context.

Parameters

s	The iLBC decode context.
mode	The frame size.
use_enhancer	TRUE to use the audio enhancer option.

Returns

A pointer to the iLBC decode context, or NULL for error.

ilbc_fillin()

int ilbc_fillin	(	ilbc_decode_state_t *	s,
		int16_t	amp[],
		int	len
	)

Produce linear PCM data to fill in where received iLBC data is missing.

Parameters

s	The iLBC context.
amp	The audio sample buffer.
len

Returns

The number of samples returned.
