FLAC (Free Lossless Audio Codec) is an audio format similar to MP3, but it is a lossless encoding format, meaning that audio is compressed in FLAC without any loss in quality. FLAC is unique as it is the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, …
HRTF (Head Related Transfer Functions) refers to a technique used in audio recordings in order to produce binaural signals from a monaural source. While monaural signals refer to sounds that a signal source produces and both ears hear them at varying distances and frequencies, binaural signals refer to sounds that two separate sources produce and that each ear …
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 …
The Need for Wireless Speakers A common complaint against home audio systems has been the cables that interconnect the speakers to the audio receiver, tuner, cd player, or stereo units. As more and more channels are added to modern home audio equipment the problem of connecting the speakers to the audio sources has exacerbated. Running …
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 …
A hydrophone is a type of microphone that is specifically designed to be used under water. Hydrophones depend on piezoelectric transducers to detect sound waves and other pressure waves coming from underwater vehicles, animals, and natural structures. Hydrophones were widely used in World War I, and II to detect U-boats (German submarines) and are still …
Noise-canceling headphones are headsets that have the ability not just to block out noise but to cancel it using the properties of sound waves. Sound waves have compression and rarefaction characteristics similar to the crests and troughs of a transverse wave. They also have amplitude and frequency characteristics. These characteristics of sound waves are used …
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 …
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. The …
