      I2S (Inter-IC Sound)

      I2S is Inter-IC Sound. I2S is a serial bus used to transport digital audio. High-end CD and DVD players feature I2S outputs. I2S inputs are found on some PC sound cards. I2S Pinouts Pin Purpose 1 Word Clock (WCLK) 2 Bit Clock (BCLK) 3 DATA 4 Master Clock (MCLK) 5 DEM The pins on the

      AES/EBU

      Experts in science and technology developed a known digital audio standard, AES/EBU, to handle signals from digital audio systems. It is known officially by the name AES3 and an Audio Engineering Society and the European Broadcasting Union developed it, hence the name. It was first publicized in 1989, but was revised later in 1995, 1998,

      Voice Changer

      A voice changer is exactly what the name states; it changes the sound of your voice. In addition, many voice changers can go further than just changing the sound of your voice, many voice changers can change the gender of a voice (for instance, from female to male) and enhance the voice in many different

      How to Measure Sound Quality

      There are many ways to measure sound quality. Many measurements have been created to specifically measure and rate the quality of sound. Here are a few of the most common types of measurements used for sound quality. THD THD stands for Total Harmonic Distortion. It is a measurement taken to view the total amount of

    • Automatic Gain Control

      Automatic Gain Control

      Automatic gain control is a technique implemented in many consumer electronics that automatically adjusts the input levels of a system by inducing a portion of the output levels in the input terminals. Automatic gain control is used in a wide variety of technologies, including telecommunications, navigation, audio/video recordings, and radio systems. Automatic gain control can

    • How to Measure Signal Quality

      How to Measure Signal Quality

      Most people usually look to Signal to Noise Ratio to measure the signal quality of either audio or video communications. Signal to noise ratio is usually written either S/N or SNR. Most of the time the signal to noise ratio is measured in decibels. A decibel is a measure of power or loudness. Not to

    • Who Invented the Microphone?

      Who Invented the Microphone?

      A microphone is a device that converts acoustic power into electric power. Both the acoustic power and the electric power have similar wave characteristics that convert sound waves into electric voltages that eventually convert back into sound waves through speakers. Microphone were used with the first telephones, and then with radio transmitters soon after. Sir

    • Signal to Noise Ratio

      Signal to Noise Ratio

      The Signal to Noise Ratio is a ratio of desired signal to undesired signal (noise) in the average power level of a transmission. The signal is what you are measuring that is the result of the presence of your analyte. Noise is extraneous information that can interfere with or alter the signal. It can not

      Breakout Box

      A breakout box is a device in which a multi-cable electric line is split into its component cables in order to allow for testing or signal enhancement. There are two main types of breakout boxes. They include breakout boxes that are built to enhance or customize audio or visual signals and breakout boxes that are

      TOSLINK

      TOSLINK or Toshiba – LINK is a connection standard for digital audio streams. It is a standard which uses fiber optic cables. The important feature of fiber optic cables is that they convert audio signals into light impulses as opposed to electric signals. TOSLINK cables usually transmit their signals as the red LED lights.
