Sount Check 2 Audio Test and Demonstration CD (lossless)
SOUND CHECK 2 is the definitive audio test disc. Created in association with renowned record producer, engineer and musician
Alan Parsons, it is available as a single CD or in a double CD case with built-in microphone and sound level meter, calibrated
from -15dB to +12dB. When used in conjunction with its third octave tracks, SOUND CHECK 2 forms an instant system response
analyser.
It contains 99 tracks of practical material compiled as a result of careful research and investigation into the needs of studio
engineers, audio technicians, serious audiophiles, record producers and musicians. The disc has been designed not only to
help assess the technical performance of a wide range of sound recording and reproduction equipment, but also to offer the
very best available musical, vocal and effects sources for experimentation and demonstration.
