ADSRReader::ADSRReader | ( | std::shared_ptr< IReader > | reader, |
float | attack, | ||
float | decay, | ||
float | sustain, | ||
float | release ) |
Creates a new ADSR reader.
reader | The reader to read from. |
attack | The attack time in seconds. |
decay | The decay time in seconds. |
sustain | The sustain level, should be in range [0 - 1]. |
release | The release time in seconds. |
|
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. |
