Some head units have built-in stereo amplifiers. Other car audio systems use a separate stand-alone amplifier. Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit. Coaxial speakers: These are the most common type of car speakers and are often factory-installed.
A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate sound from the same point or axis. Two general types exist: one is a compact design using two or three speaker drivers, usually in car audio, and the other is a two-way high-power design for professional audio, also known as single-source or dual-concentric loudspeakers.

In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal.In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel.
Full Reference Methods (FR): FR models compute the quality difference by comparing the original video signal against the received video signal. Typically, every pixel from the source is compared against the corresponding pixel in the received video, with no knowledge about the encoding or transmission process in between.
The Cinerama audio soundtrack technology, developed by Hazard E. Reeves, utilized seven discrete sound tracks on full-coat magnetic 35 mm film. The system featured five main channels behind the screen, two surround channels in the rear of the theater, plus a sync track to interlock the four machines, which were specially outfitted with aircraft ...
A Bitcrusher is an audio effect that produces distortion by reducing the resolution or bandwidth of digital audio data. The resulting quantization noise may produce a "warmer" sound impression, or a harsh one, depending on the amount of reduction.
THX introduced Spatial Audio in 2018, a new positional audio solution for an immersive 360-degree sound experience through headphones and speakers. [31] The technology was used on the Kraken gaming headset for simulated 7.1 surround sound. These headphones were included with a Spatial Audio app. This would be later used on Windows 10 devices.

T-Pain became so associated with Auto-Tune that he had an iPhone app named after him that simulated the effect, "I Am T-Pain". [23] Eventually dubbed the "T-Pain effect", [ 7 ] the use of Auto-Tune became a fixture of late 2000s music, where it was used in other hip hop/R&B artists' works, including Snoop Dogg 's single " Sexual Eruption ...
