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 …
Conceptually, hypersonic sound (HSS) systems do to sound what laser technology does to light – focus sound into a tight beam that can travel great distances without dispersing. HSS systems can create sound that is meant only for a certain individual(s), not for everyone who just happens to be in the vicinity. HSS Speakers versus …
SPDIF, or the Sony/Philips Digital Interconnect Format) is used to carry or transport digital audio signals in consumer electronic equipment such as CD and DVD players, PC audio cards, and car audio systems over short distances. The digital signal can be carried over fiber optic (TOSLINK connectors) or coaxial cable (RCA connectors) and is also …
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, …
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, …
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 …
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 …
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 …
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 …
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 …
