His true breakthrough came with his groundbreaking engineering work on Pink Floyd's 1973 masterpiece, The Dark Side of the Moon . The album became a benchmark for multi-track recording, spatial panning, and experimental sound effects. Parsons brought this same obsessive attention to detail, frequency balance, and spatial clarity to his own musical endeavor, The Alan Parsons Project, and ultimately, into the creation of his Sound Check audio calibration series. What is the Sound Check 2 CD?
Ideal for verifying stereo imaging and checking if speaker polarities are correct (in-phase vs. out-of-phase).
Searching for this title followed by "rar" or "exclusive" often leads to unofficial file-sharing sites. What is the Sound Check 2 CD
The disc features isolated pink noise bands ranging from 20Hz (sub-bass) up to 20kHz (air/high frequencies).
Used to map out the frequency response of your room or speakers. Searching for this title followed by "rar" or
Unlike white noise, pink noise has equal energy per octave, closely mimicking how human ears perceive loudness across the frequency spectrum. The disc provides pink noise tracks for individual left and right channels, as well as phase-correlated tracks to test speaker polarity.
Use tracks 1 through 32 in combination with a calibrated microphone and a Real-Time Analyzer (RTA) software/hardware setup. This helps you see which frequencies are bouncing unevenly in your room. Because human hearing is logarithmic
Essential for loudspeaker and room measurements. Sweep Tones: Used to pinpoint system resonances.
As a reminder of his remarkable achievements, the "Sound Check 2" CD continues to push the boundaries of sound quality and challenge the limits of audio equipment. For those willing to take the challenge, this exclusive audio test and demonstration CD is an unparalleled resource that will continue to inspire and educate for years to come.
Pink noise is a signal that contains equal energy per octave. Because human hearing is logarithmic, pink noise sounds perfectly balanced to our ears, making it the ideal tool for acoustic analysis.
: When used with the 1/3 octave tracks, the disc can act as an instant analyzer for room acoustics and speaker alignment. Dry Vocal References : Includes unprocessed vocal recordings of Alan Parsons, Luciano Pavarotti , and Catherine Bott to test mid-range reproduction. Instrumental Fidelity
