virtual AudioInfo | audioInfo () |
void | begin () override |
virtual void | begin (AudioInfo info) |
void | end () override |
virtual bool | isResultPCM () |
If true, the decoding result is PCM data. | |
operator bool () override | |
virtual void | setAudioInfo (AudioInfo from) override |
for most decoders this is not needed | |

set bocksizes as 2^pow: range from 8 to 15 | |
void | setLookahead (int value) |
Set look ahead bytes from 0 to 8. | |
void | setNoiseShaping (ADPCMNoiseShaping ns) |
Defines the noise shaping. | |
void | setNotifyAudioChange (AudioInfoSupport ¬ify) override |
Registers an object that is notified if the audio format is changing. | |
virtual void | setOutput (AudioOutput &out_stream) |
Defines where the decoded result is written to. | |
virtual void | setOutput (AudioStream &out_stream) |
Defines where the decoded result is written to. | |
virtual void | setOutput (Print &out_stream) |
Defines where the decoded result is written to. | |
