For the ADPCM system, these two parameters are defined as
Thus one is led to ADPCM data compression, quickly becoming a standard on most cards.
The KX1400 supports both 12-bit PCM and 4-bit IMA ADPCM data formats, and has a built-in tone generator capable of generating tones at 4,096 different frequencies.
With AuriStream, CSR has introduced Adaptive Differential Pulse Code Modulation (ADPCM) as an enhanced voice coding method, since ADPCM scans at 32 Kbps, CVSD 64 Kbps for Bluetooth power savings in the handset.
Initially, the ADPCM audio decoding chip set will be made available by drive manufacturers and other third parties, such as Optical Media International, on a separate card or piggyback card to a CD-ROM drive interface card.
CSR aptX technology uses advanced ADPCM principles to squeeze the entire 10Hz-22kHz high fidelity audio frequency range neatly within the limited bandwidth of Bluetooth transmission standards to deliver high quality stereo audio reproduction with extremely low latency that avoids lip-sync issues when used with in-vehicle video entertainment systems.
Marathon's alternatives were adding another T1 between Houston and Findlay, or ADPCM (adaptive differential pulse code modulation) to compress the voice traffic and make more efficient use of the T1 capacity.
CSR's aptX technology uses advanced ADPCM principles to squeeze the entire 10Hz - 22kHz high-fidelity audio frequency range neatly within the constrained bandwidth of Bluetooth transmission standards.
ADPCM done with Tellabs equipment compresses a DS0 circuit to 32kb/s, so instead of 24 channels on a T1, they get 48.
