Its design and implementation - * is modeled after the CVSD encoder/decoder specifications defined in the - * Bluetooth standard. - * - * \ingroup vocoder_blk - * - * CVSD is a method for encoding speech that seeks to reduce the - * bandwidth required for digital voice transmission. CVSD takes - * advantage of strong correlation between samples, quantizing the - * difference in amplitude between two consecutive samples.

More - * specifically, for each incoming input bit, the decoder outputs one - * audio sample. If the input is a "1" bit, the internal reference is - * increased appropriately and then outputted as the next estimated audio - * sample. If the input is a "0" bit, the internal reference is - * decreased appropriately and then likewise outputted as the next estimated - * audio sample. Grouping 8 input bits together, the encoder essentially - * produces 8 output audio samples for everyone one input byte. - * - * This decoder requires that output audio samples are 2-byte short signed - * integers. The result bandwidth conversion, therefore, is 1 byte of - * encoded audio data to 16 output bytes of raw audio data. - * - * The CVSD decoder module must be post-fixed by a down-converter to - * under-sample the audio data after decoding.
