What is CVSD in Bluetooth?
Continuously variable slope delta modulation (CVSD or CVSDM) is a voice coding method. It is a delta modulation with variable step size (i.e., special case of adaptive delta modulation), first proposed by Greefkes and Riemens in 1970.
What is CVSD codec?
Description. CVSD Codec (Continuously Variable Slope Delta Modulation) is used in both commercial and military communications where “toll-quality” is required, yet low computation complexity and low memory requirements are desirable. As the name implies it is Delta modulation (DM*) with variable step size.
What is CVSD audio?
Continuously variable slope delta (CVSD) source encoding is used for data compression of audio signals. CVSD is a lossy compression whose quality is directly related to the sampling frequency and is generally most practical for speech applications.
What does CVSD stand for?
Continuously Variable Slope Delta (modulation)
