AUD_LinearResampleReader::AUD_LinearResampleReader | ( | AUD_Reference< AUD_IReader > | reader, |
AUD_Specs | specs | ||
) |
Creates a resampling reader.
reader | The reader to mix. |
specs | The target specification. |

int AUD_LinearResampleReader::getLength | ( | ) | const [virtual] |
Returns an approximated length of the source in samples.

int AUD_LinearResampleReader::getPosition | ( | ) | const [virtual] |
Returns the position of the source as a sample count value.

void AUD_LinearResampleReader::read | ( | int & | length, |
bool & | eos, | ||
sample_t * | buffer | ||
) | [virtual] |
Request to read the next length samples out of the source. The buffer supplied has the needed size.
[in,out] | length | The count of samples that should be read. Shall contain the real count of samples after reading, in case there were only fewer samples available. A smaller value also indicates the end of the reader. |
[out] | eos | End of stream, whether the end is reached or not. |
[in] | buffer | The pointer to the buffer to read into. |

void AUD_LinearResampleReader::seek | ( | int | position | ) | [virtual] |
Seeks to a specific position in the source.
position | The position to seek for measured in samples. To get from a given time to the samples you simply have to multiply the time value in seconds with the sample rate of the reader. |
