Inheritance diagram for VS1053Stream:
Public Member Functions | |
| virtual AudioInfo | audioInfo () override |
| 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. | |
| 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 | |
| operator bool () | |
| virtual size_t | readBytes (uint8_t *buffer, size_t length) |
| virtual size_t | readSilence (uint8_t *buffer, size_t length) |
| Source to generate silence: just sets the buffer to 0. | |
| void | setAudioInfo (AudioInfo c) |
| 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! | |
| virtual void | setNotifyAudioChange (AudioInfoSupport &bi) override |
| void | setVolume (float vol) |
| value from 0 to 1.0 | |
| virtual bool | validate (AudioInfo &info) |
| float | volume () |
| provides the volume | |
| virtual size_t | write (const uint8_t *buffer, size_t size) override |
| Write audio data. | |
| virtual size_t | write (uint8_t ch) override |
| virtual void | writeSilence (size_t len) |
| Writes len bytes of silence (=0). | |
