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 () override
 
virtual bool begin (AudioInfo info) override
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
void end () override
 
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 () override
 
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 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.
 
void setOutput (Print &out_stream) override
 Defines the output Stream.
 
virtual size_t write (const uint8_t *data, size_t len) override
 Converts data from float to int16_t.

Constructor & Destructor Documentation

◆ DecoderFloat() [1/2]

DecoderFloat ( Print out_stream,
bool  active = true 
)
inline

Construct a new DecoderFloat object.

Parameters
out_streamOutput Stream to which we write the decoded result

◆ DecoderFloat() [2/2]

DecoderFloat ( Print out_stream,
AudioInfoSupport bi 
)
inline

Construct a new DecoderFloat object.

Parameters
out_streamOutput Stream to which we write the decoded result
biObject that will be notified about the Audio Formt (Changes)
