Member Function Documentation

audioInfo()

AudioInfo audioInfo ( )

inlinevirtualinherited

provides the actual input AudioInfo

Implements AudioInfoSupport.

Reimplemented in CodecNOP, and BinaryContainerEncoder.

audioInfoOut()

virtual AudioInfo audioInfoOut ( )

inlinevirtualinherited

provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

Reimplemented in PureDataStream, PWMAudioOutput, ChannelFormatConverterStreamT< T >, ChannelFormatConverterStream, NumberFormatConverterStreamT< TFrom, TTo >, NumberFormatConverterStream, FormatConverterStream, Pipeline, and ResampleStream.

begin() [1/2]

bool begin ( )

inlineoverridevirtualinherited

Implements AudioWriter.

begin() [2/2]

virtual bool begin ( AudioInfo  info )

inlinevirtualinherited

Reimplemented in AACEncoderFDK.

end()

void end ( )

inlineoverridevirtualinherited

Implements AudioWriter.

mime()

const char * mime ( )

inlineoverridevirtualinherited

Provides the mime type of the encoded result.

Implements AudioEncoder.

operator bool()

operator bool ( )

inlinevirtualinherited

Implements AudioWriter.

setAudioInfo()

virtual void setAudioInfo ( AudioInfo  from )

inlinevirtualinherited

Defines the sample rate, number of channels and bits per sample.

Reimplemented from AudioEncoder.

setOutput()

void setOutput ( Print &  out_stream )

inlineoverridevirtualinherited

Implements AudioWriter.

write()

size_t write ( const uint8_t *  data, size_t  len  )

inlineoverridevirtualinherited

Implements AudioWriter.
