Public Member Functions | |
virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
Adds target to be notified about audio changes. | |
virtual AudioInfo | audioInfo () override |
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 | |
virtual int | available () override |
virtual int | availableForWrite () override |
float | balance () |
Get the currenet balance setting (-1.0..1.0) | |
bool | begin () |
Starts with the default config or restarts. | |
bool | begin (VS1053Config cfg) |
Starts with the indicated configuration. | |
virtual void | clearNotifyAudioChange () |
Deletes all change notify subscriptions. | |
VS1053Config | defaultConfig (RxTxMode mode=TX_MODE) |
void | end () |
Stops the processing and releases the memory. | |
virtual void | flush () override |
VS1053 & | getVS1053 () |
returns the VS1053 object | |
bool | isNotifyActive () |
Checks if the automatic AudioInfo update is active. | |
virtual | operator bool () |
virtual size_t | readBytes (uint8_t *data, size_t len) override |
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 c) |
Defines the input AudioInfo. | |
void | setAudioInfo (VS1053Config c) |
defines the default configuration that is used with the next begin() | |
void | setBalance (float bal) |
Adjusting the left and right volume balance, higher to enhance the right side, lower to enhance the left side. | |
bool | setEncoder (AudioEncoder *enc) |
Defines an alternative encoder that will be used (e.g. MP3Encoder). It must be allocated on the heap! | |
void | setNotifyActive (bool flag) |
Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
bool | setVolume (float vol) override |
value from 0 to 1.0 | |
float | volume () override |
provides the volume | |
virtual size_t | write (const uint8_t *data, size_t len) override |
Write audio data. | |
virtual size_t | write (uint8_t ch) override |
virtual void | writeSilence (size_t len) |
Writes len bytes of silence (=0). | |
