(8 times oversampling) A digital filter which calculates 7 additional samples between the actual samples, which provides a closer representation the original analog signal, and therefore better sound quality.
A popular compression scheme used widely on the Internet. MP3 uses anywhere from 8kbps to 320kbps for compression, with the higher bit rates offering correspondingly better sound quality. Most software packages used to "rip" MP3s from CD audio (converting CD audio to MP3) allow for what's known as "ID3 Tags" — a text component of the digital music file which contains Track, Album, Artist, Genre, Year, and comment information.
A Custom File feature that allows the user to assign an eight character name to a tuner frequency.
Proprietary circuitry induces subtle phase shift in the preamp output of the head unit, different in each output channel, to simulate a sound source that is higher in origin. The frequency response in a section of the sound is altered, to further enhance the perception that the sound is originating from a physically higher source. These two factors, combine to seemingly raise the sound stage, and spread it wider across the dash, even if the speakers are mounted low in the doors.
A feature set that offers both a user adjustable high pass filter and low pass filter built right into the head unit, in which the output is sent to both the speaker level outputs and the RCA outputs.
Provides superior protection against mistracking through the use of an isolated disc tray, a quick focus optic array joined with a higher disc RPM, a redesigned damper using agel for better shock isolation, and a memory circuit.
Adaptive Transform Acoustic Coding. The process used in MiniDisc that utilizes psychoacoustic principles to limit quantization noise and compress the data stream from 16 bits to 4 bits by using non-uniform frequency and time division.
A built-in equalization circuit providing seven bands of frequency level adjustment, stored in 7 user-adjustable presets.
Sony's proprietary SSIR-EX tuner technology which can actually adjust the tuner's bandwidth, depending on current environmental conditions. Improved sound quality and superior adjacent station interference rejection results.
A compact disc and player feature utilizing disc, track, and artist information encoded directly on the CD media. Both playback and media components must have CD Text compatibility.
