Classes
class	AACEncoderFDK
	Encodes PCM data to the AAC format and writes the result to a stream This is basically just a wrapper using https://github.com/pschatzmann/arduino-fdk-aac. More...
class	ADPCMEncoder
	Encoder for ADPCM - Depends on https://github.com/pschatzmann/adpcm. More...
class	ADPCMEncoderXQ
	Encoder for ADPCM-XQ - Depends on https://github.com/pschatzmann/arduino-adpcm-xq. More...
class	APTXEncoder
	Encoder for OpenAptx - Depends on https://github.com/pschatzmann/libopenaptx. More...
class	BinaryContainerEncoder
	Wraps the encoded data into Config, Data, and Meta segments so that we can recover the audio configuration and orignial segments if this is relevant. We assume that a full segment is written with each call of write(); The segments are separated with a new line character. More...
class	Codec2Encoder
	Encoder for Codec2 - Depends on https://github.com/pschatzmann/arduino-libcodec2. More...
class	CopyEncoder
	Dummy Encoder which just copies the provided data to the output. More...
class	EncoderBase64
	EncoderBase64s - Encodes the input data into a Base64 string. By default each audio frame is followed by a new line, so that we can easily resynchronize the reading of a data stream. The generation of the new line can be configured with the setNewLine() method. More...
class	EncoderBasic
	EncoderBasic - supports mime type audio/basic. The content of the "audio/basic" subtype is single channel audio encoded using 8bit ISDN mu-law [PCM] at a sample rate of 8000 Hz. Requires https://github.com/pschatzmann/arduino-libg7xx. More...
class	EncoderFloat
	EncoderFloats - Encodes 16 bit PCM data stream to floats data. More...
class	EncoderL16
	EncoderL16s - Condenses 16 bit PCM data stream to 8 bits data. Most microcontrollers can not process 8 bit audio data directly. 8 bit data however is very memory efficient and helps if you need to store audio on constrained resources. This encoder translates 16bit data into 8bit data. More...
class	EncoderL8
	EncoderL8s - Condenses 16 bit PCM data stream to 8 bits data. Most microcontrollers can not process 8 bit audio data directly. 8 bit data however is very memory efficient and helps if you need to store audio on constrained resources. This encoder translates 16bit data into 8bit data. By default the encoded data is represented as uint8_t, so the values are from 0 to 255. More...
class	FLACEncoder
	FLACEncoder. More...
class	G711_ALAWEncoder
	64 kbit/s g711 ALOW Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	G711_ULAWEncoder
	64 kbit/s g711 ULOW Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	G711Decoder
	64 kbit/s g711 ULOW Decoder based on https://github.com/pschatzmann/arduino-libg7xx Supported decoder parameters: alaw2linear, ulaw2linear More...
class	G721Encoder
	32Kbps G721 Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	G722Encoder
	Encoder for G.722 - Depends on https://github.com/pschatzmann/arduino-libg722. Inspired by g722enc.c. More...
class	G723_24Encoder
	24Kbps G723 Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	G723_40Encoder
	40Kbps G723 Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	G7xxEncoder
	g723_24, g721, g723_40 Encoder based on https://github.com/pschatzmann/arduino-libg7xx More...
class	GSMEncoder
	Encoder for GSM - Depends on https://github.com/pschatzmann/arduino-libgsm. Inspired by gsmenc.c. More...
class	ILBCEncoder
	Encoder for iLBC - Depends on https://github.com/pschatzmann/libopenilbc. More...
class	LC3Encoder
	Encoder for LC3 - Depends on https://github.com/pschatzmann/arduino-liblc3. More...
class	MP3EncoderLAME
	Encodes PCM data to the MP3 format and writes the result to a stream This is basically just a wrapper using https://github.com/pschatzmann/arduino-liblame. More...
class	OggContainerEncoder
	Encoder for Ogg Container. Encodes a packet for an Ogg container. The Ogg begin segment contains the AudioInfo structure. You can subclass ond overwrite the writeHeader() method to implement your own header logic. When an optional encoder is specified in the constructor we package the encoded data. Dependency: https://github.com/pschatzmann/arduino-libopus. More...
class	OpusAudioEncoder
	OpusAudioEncoder: Dependens on https://github.com/pschatzmann/arduino-libopus.git. More...
class	OpusOggEncoder
	Opus Encoder which uses the Ogg Container: see https://datatracker.ietf.org/doc/html/rfc7845 Dependency: https://github.com/pschatzmann/arduino-libopus. More...
class	SBCEncoder
	Encoder for SBC - Depends on https://github.com/pschatzmann/arduino-libsbc. Inspired by sbcenc.c. More...
class	WAVEncoder
	A simple WAV file encoder. If no AudioEncoderExt is specified the WAV file contains PCM data, otherwise it is encoded as ADPCM. The WAV header is written with the first writing of audio data. Calling begin() is making sure that the header is written again. More...
