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.
Speaker drivers are the primary means for sound reproduction. They are used among other places in audio applications such as loudspeakers, headphones, telephones, megaphones, instrument amplifiers, television and monitor speakers, public address systems, portable radios, toys, and in many electronics devices that are designed to emit sound.
For example, music can be streamed from a mobile phone to a wireless headset, hearing aid/cochlear implant streamer, or car audio; alternately from a laptop/desktop to a wireless headset; also, voice can be streamed from a microphone device to a recorder on a PC. [1] The Audio/Video Remote Control Profile (AVRCP) is often used in conjunction ...
Wireless control of and communication with iOS and Android device phones, tablets and portable wireless speakers. [41] Wireless Bluetooth headset and intercom. Idiomatically, a headset is sometimes called "a Bluetooth". Wireless streaming of audio to headphones with or without communication capabilities.
A noise-cancellation speaker emits a sound wave with the same amplitude but with an inverted phase (also known as antiphase) relative to the original sound. The waves combine to form a new wave, in a process called interference , and effectively cancel each other out – an effect which is called destructive interference .
The ratio of (a) total received power, i.e., the signal to (b) the noise-plus-distortion power. This is modeled by the equation above. [2] The ratio of (a) the power of a test signal, i.e. a sine wave, to (b) the residual received power, i.e. noise-plus-distortion power. With this definition, it is possible to have a SINAD level less than one.
In audio systems, lower distortion means that the components in a loudspeaker, amplifier or microphone or other equipment produce a more accurate reproduction of an audio recording. In radio communications, devices with lower THD tend to produce less unintentional interference with other electronic devices.
Most devices capable of compressing audio dynamics can also be used to reduce the volume of one audio source when another audio source reaches a certain level; this is called side-chaining. [13] In electronic dance music , side-chaining is often used on basslines , controlled by the kick drum or a similar percussive trigger, to prevent the two ...
