Inheritance diagram for Throttle:
Public Member Functions | |
| Throttle (Print &out) | |
| Throttle (Stream &io) | |
| 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 | |
| int | available () |
| int | availableForWrite () |
| bool | begin () |
| bool | begin (AudioInfo info) |
| bool | begin (ThrottleConfig cfg) |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| ThrottleConfig | defaultConfig () |

| virtual void | end () |
| virtual void | flush () override |
| int64_t | getDelayMs (uint64_t frames) |
| int64_t | getDelaySec (uint64_t frames) |
| int64_t | getDelayUs (uint64_t frames) |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| operator bool () | |
| size_t | readBytes (uint8_t *data, size_t len) |
| 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. | |
| virtual void | setAudioInfo (AudioInfo newInfo) override |
| Defines the input AudioInfo. | |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| void | setOutput (Print &out) override |
| Defines/Changes the output target. | |
| void | setStream (Stream &io) override |
| Defines/Changes the input & output. | |
| void | startDelay () |
| size_t | write (const uint8_t *data, size_t len) |
| virtual size_t | write (uint8_t ch) override |
| virtual void | writeSilence (size_t len) |
| Writes len bytes of silence (=0). | |
