Inheritance diagram for ADPCMDecoderXQ:
Public Member Functions | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| virtual AudioInfo | audioInfo () |
| provides the actual input AudioInfo | |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| bool | begin () override |
| virtual bool | begin (AudioInfo info) override |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| void | end () override |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual bool | isResultPCM () |
| Returns true to indicate that the decoding result is PCM data. | |
| operator bool () override | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| virtual void | setAudioInfo (AudioInfo from) override |
| for most decoders this is not needed | |
| void | setBlockSizePower (int pow) |
| 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 | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| 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. | |
| virtual size_t | write (const uint8_t *data, size_t len) |
Public Attributes | |
| int | id |
| custom id to be used by application | |
