| MozziStream (Stream &in) | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| 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 | |

| int | getAudioInput () |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual | operator bool () |
| size_t | readBytes (uint8_t *data, size_t len) |
| Provides the data filled by calling updateAudio() | |
| virtual size_t | readSilence (uint8_t *buffer, size_t length) |
| Source to generate silence: just sets the buffer to 0. | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| void | setAudioInfo (AudioInfo info) |
| Defines the input AudioInfo. | |
| void | setInput (Stream &in) |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| virtual bool | setVolume (float volume) |
| define the actual volume in the range of 0.0f to 1.0f | |
| bool | setVolume (int16_t vol) |
| Defines the multiplication factor to scale the Mozzi value range to int16_t. | |
| virtual float | volume () |
| provides the actual volume in the range of 0.0f to 1.0f | |
| size_t | write (const uint8_t *data, size_t len) |
| Write data to buffer so that we can access them by calling getAudioInput() | |
| virtual size_t | write (uint8_t ch) override |
| virtual void | writeSilence (size_t len) |
| Writes len bytes of silence (=0). | |

Gets the next audio value either from the assigned Input Stream or the buffer that was filled by write(). The data range is defined in MozziConfig
