Public Member Functions

 GSMEncoder (bool scaling=true)
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 ()
virtual bool begin (AudioInfo info)
virtual void end ()
virtual const char * mime ()
 Provides the mime type of the encoded result.
 operator bool ()
void setAudioInfo (AudioInfo from) override
 Defines the sample rate, number of channels and bits per sample.
virtual void setOutput (Print &out_stream)
virtual size_t write (const uint8_t *data, size_t len)
