Outlet. Articles & Videos. Autosound 2000 has created this series of test CDs for the professional and the serious hobbyist. Each disc is designed to test a specific performance parameter of your vehicle's audio system. Disc One contains 99 tracks, many of which focus on bass. You get 20-20,000 Hz sweeps, low frequency bursts, sine waves, and other useful tracks.
Disc Two includes 32 tracks that help you evaluate and improve your system's stereo imaging. Disc Three covers a broader range of musical styles. Non-music tracks include human voices at various spots on a typical soundstage as well as various levels of distortion. The liner notes tell you how to use each selection.
Disc Four is billed as the Ultimate Amplifier Level Setting Disc. The name says it all. Disc Five was created to demonstrate different characteristics and specifications of an audio system. You save about $10 when you buy the five-disc set.
Overview: The Autosound 2000 Test CDs are designed for testing specific parameters of your vehicle's audio system. The disc and track information is as follows: Disc 1: Low Frequency Tests. Track 1: 1 kHz tone at -20 DB (2:06) Helps you measure the reference loudness of a component. Track 2: 1 kHz tone at -20 dB, fades to black (3:55) Tests the reproduction quality of a sound system when driven with extremely low level signals.
Track 3: Polarity Pulses (3 positive - 1 negative) (2:00) To measure relative and absolute polarity. Track 4: 20-20,000 Hz slow sweep (1:10) To take response measurements and to check for resonant frequencies. Track 5: 20-20,000 Hz fast sweep (:19). Track 6: Sequential tones 20-20,000 Hz, twice (1:36) For use with test instruments that measure sequential tones. Track 7: Composite tones (2:04) Used for measurements with swept spectrum analyzers and to determine the overload threshold of a system.

Track 8: 50 Hz square wave with sweep to 20 Hz (2:00) Used for setting up low-frequency servo systems. Track 9: Low-frequency bursts (1:27) Used to evaluate the transient behavior of a subwoofer system. Tracks 10-98: Sine waves corresponding to track numbers (:30 each) The numerical track indicator of the CD player matches with the frequency of the sine wave that is recorded on that track, eg., track 10 = 10Hz. Track 99: 1 kHz at digital zero (2:36) Used to test the output headroom of a CD player.
Hey people A while back, long before i got a new computer, i had either paid to download, or just downloaded two cd's worth of music. Each cd had like 16 songs, which were essentially test tones along with the first song being instructions which was nice. This part probably won't make much sense but it had various test tones at a 2:1 ration and 3:1 ratio (or something similar to that). Anywho, made it a lot easier for setting the gains for the subs. Essentially picked the ratio you wanted (ratio may not be the correct word/name) and then chose it's respective track, and just listened for a change in pitch on the track as you turned the gain up. I realize the above isn't a very good explanation, but that was a solid couple of cd's that made life strangely simple for someone as anti-smrt as myself. If anyone has any idea what i'm talkin about it'd be greately appreciated.edit.
doh i think i found it, but the website doesn't appear to exist, or at least be working anymore. Anyone recognize this link: June 01, 2005, 08:23 PM: Message edited by: Hardcore Rock Superstar.
