High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
Direct Stream Digital (DSD) is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD).. DSD uses delta-sigma modulation, a form of pulse-density modulation encoding, a technique to represent audio signals in digital format, a sequence of single-bit values at a sampling rate of 2.8224 MHz.
In September 2007, the Audio Engineering Society published the results of a year-long trial, in which a range of subjects—including professional recording engineers—were asked to discern the difference between high-resolution audio sources (including SACD and DVD-Audio) and a compact disc audio (44.1 kHz/16 bit) conversion of the same ...
LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.
Sony Olympus Medical Solutions Inc. was founded on April 16, 2013, as a cooperation between Sony (owns 51%) and Olympus (owns 49%) with a goal to develop, design and sell surgical endoscopes with 4K+ resolution and 3D technologies.
AES50 is a point-to-point interconnect which carries multiple channels of AES3, PCM or DSD bitstream formats, along with system clock and synchronisation signals, over Cat 5 cable using 100 Mbit/s Fast Ethernet physical layer. AES50 uses the four pairs of the Cat 5 cable in the 8P8C connector: Audio data transmit + Audio data transmit –
