Detailed Description

AmAudio to mix in every n seconds a file

AmAudio that plays Audio A and every s seconds mixes in AudioFile B with level l. If l == 0, playback of A is not continued when playing B, which means that it continues right where it was before playback of B started.

Member Function Documentation

int AmAudioMixIn::read ( unsigned int  user_ts,
unsigned int  size 
) [inline, protected, virtual]

Gets 'size' bytes directly from stream (Read,Pull).

Implements AmAudio.

int AmAudioMixIn::write ( unsigned int  user_ts,
unsigned int  size 
) [inline, protected, virtual]

Puts 'size' bytes directly from stream (Write,Push).

Implements AmAudio.

int AmAudioMixIn::get ( unsigned int  user_ts,
unsigned char *  buffer,
unsigned int  nb_samples 
) [protected, virtual]

Get some samples from input stream.

Warning:
For packet based payloads / file formats, use: 
           nb_sample = input buffer size / sample size of the reference format
whereby the format with/from which the codec works is the reference one.
Returns:
# bytes read, else -1 if error (0 is OK)

Reimplemented from AmAudio.

int AmAudioMixIn::put ( unsigned int  user_ts,
unsigned char *  buffer,
unsigned int  size 
) [protected, virtual]

Put some samples to the output stream.

Warning:
For packet based payloads / file formats, use: 
           nb_sample = input buffer size / sample size of the reference format
whereby the format with/from which the codec works is the reference one.
Returns:
# bytes written, else -1 if error (0 is OK)

Reimplemented from AmAudio.
