Contains 99 tracks specifically designed and recorded for performing electronic and acoustic tests on audio systems
You can find low frequency resonance's in audio listening environments
Perform measurements on woofers and enclosures
Evaluate low level resolution of CD players and headunits
Woofer measurements include impedance, which can be plotted by using CD#101 in a CD player, a resistor, and a VOM (Volt-Ohm Meter)
Complete instructions are shipped with each disc
If you're serious about audio, this disc is a must-have

Track List:
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: Frequencies corresponding to track numbers. The numerical track indicator of the CD player matches with the frequency that is recorded on that track, for example, track 10 = 10Hz
Track 99: 1 kHz at digital zero (2:36) Used to test the output headroom of a CD player
the selection is great and the pricing was phenomenal. shipping was great and the products are new in the box. i bought this time for Christmas gifts but will be returning when its my turn.
thanks!!
