CVSD Codec encodes voice signals at 1 bit per sample, so that audio sampled at 16kHz is encoded at 16 kbps. Sampling Rate: 8 kHz Coding Rate = 8000 bps. Sampling Rate: 12khz Coding Rate = 12000 bps. Sampling Rate: 16khz Coding Rate = 16000 bps.

Encoding/Decoding Technique Encodes at 1 bit per sample. The technique to encode and decode the band-limited audio signal is CVSD modulation. A CVSD converter consists of an encoder-decoder pair. The decoder is connected in a feedback path. The encoder receives a band-limited audio signal and compares it to the analog output of the decoder. Encoding in CVSD
CVSD Codec | Continuously Variable Slope Delta Modulation
https://www.vocal.com/speech-coders/cvsd/
CVSD is a delta modulation technique which uses an adaptive step size. The CVSD encoder compares the input signal with a reference signal. If the input signal is greater than the reference signal, then a 1 is encode, otherwise a 0. The delta slope is modified based on the previously encoded bits. Consecutive 1s or 0s will increase the step size, while alternating values will …

CVSD codec - ntCVSD. The growth in wireless communication systems, cellular mobile radio and VoIP technology has created the imperative need for bandwidth efficient, high speed quality voice coding algorithms. The fundamental principle of the CVSD algorithm is the encoding of one bit per sample. For example an audio signal sampled at 32 KHz will be compressed to 32 Kbps.

Continuously variable slope delta modulation (CVSD or CVSDM) is an audio encoding method. It is a delta modulation with variable step size [4]. Due to variation in step size slope overload error is decreases as compare to delta modulation. The CVSD modulation is a technique of digitizing a band-limited audio signal. The CVSD modulator

The CVSD bit rate for encoding the band-limited audio signal is a function of the desired audio quality and the PCM format characteristics. The minimum and maximum CVSD bit rates will not be specified. Appendix F contains performance criteria for the CVSD encoder and decoder when operated at 16 or 32 kilobits/second. 5.6 CVSD Word Structure
