Constructor & Destructor Documentation
| AUD_BaseIIRFilterReader::AUD_BaseIIRFilterReader | ( | AUD_IReader * | reader, |
| int | in, | ||
| int | out | ||
| ) | [protected] |
Creates a new base IIR filter reader.
- Parameters:
-
reader The reader to read from. in The count of past input samples needed. out The count of past output samples needed.

Member Function Documentation
| virtual sample_t AUD_BaseIIRFilterReader::filter | ( | ) | [pure virtual] |
Implemented in AUD_CallbackIIRFilterReader, and AUD_IIRFilterReader.
Referenced by read().
| void AUD_BaseIIRFilterReader::read | ( | int & | length, |
| sample_t *& | buffer | ||
| ) | [virtual] |
Request to read the next length samples out of the source. The buffer for reading has to stay valid until the next call of this method or until the reader is deleted.
- Parameters:
-
[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] buffer The pointer to the buffer with the samples.
Reimplemented from AUD_EffectReader.
