function write(data: pointer; len: uint): int;

Sends more data to coder.

number of full frames processed in this call.

	`function chunkSize(): uint; virtual; abstract;`
Size of portion of data (frame) the coder is expecting to process at once. In bytes.

	`function init(sampleRate: int = 16000; bitrate: int = 24000): bool; virtual;`

function process(ptr: pointer; len: uint): int; virtual; abstract;

Encodes/decodes data.

number of full frames processed.

	`procedure close();`
Closes the coder.

	`procedure open();`
Opens the coder.

	`procedure notify(stream: pointer; sizeBytes: int); virtual;`
Called when new encoded/decoded frame is ready.

	`property framesize: int32 read f_framesize;`
Size of mono frame in samples.

	`property number_of_16bit_words_per_frame: int32 read f_number_of_16bit_words_per_frame;`
Size of frame in 16-bit words.

	`property number_of_bits_per_frame: int32 read f_number_of_bits_per_frame;`
Size of frame in bits.
