AAC Decoder using faad: https://github.com/pschatzmann/arduino-libfaad This needs a stack of around 60000 and you need to make sure that memory is allocated on PSRAM. See https://www.pschatzmann.ch/home/2023/09/12/arduino-audio-tools-faat-aac-decoder/. More...

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 () |
Starts the processing. | |
virtual bool | begin (AudioInfo info) override |
virtual void | clearNotifyAudioChange () |
Deletes all change notify subscriptions. | |
virtual void | end () |
Releases the reserved memory. | |
void | flush () |
bool | isNotifyActive () |
Checks if the automatic AudioInfo update is active. | |
virtual bool | isResultPCM () |
Returns true to indicate that the decoding result is PCM data. | |
virtual | operator bool () |
checks if the class is active | |
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 | setInputBufferSize (int len) |
Defines the input buffer size. | |
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) override |
Defines where the decoded result is written to. | |
void | setUnderflowLimit (int len) |
Defines the min number of bytes that are submitted to the decoder. | |
size_t | write (const uint8_t *data, size_t len) |
Write AAC data to decoder. | |
Public Attributes | |
