CD Ayre Cardas System Enhancement Disc Ver. 1.2
Short Glide Tone: This 60-second track contains a 45-second glide tone that sweeps from 5Hz to 20kHz, preceded by 5 seconds of silence and followed by 10-seconds of silence. This track offers a quick system "tune-up" for those times when you just can't wait five minutes for the full glide tone.
White Noise: Uncorrelated stereo white noise with a peak level of -12 dB. White nosie is purely random in nature and is chiefly used with test instruments for specialized measurements. The track lasts for 180 seconds and features a 2-second fade in and fade out.
Pink Noise: Uncorrelated stereo pink noise with a peak level of -6 dB. Pink noise is low-pass filtered to achieve equal energy in each octave, and is also commonly used with test instruments for specialized measurments. The track lasts for 180 seconds and features a 2-second fade in and fade out.
Brown Noise: Uncorrelated stereo brown noise with a peak level of -3 dB. Brown noise is low-pass filtered to closely mimic the spectral distribution of music. This signal is excellent for use in breaking-in components and cables. The track lasts for 180 seconds and features a 2-second fade in and fade out.
Mono Brown Noise: Identical noise signals in both channels. This track can be very useful when integrating sub-woofers with other lous-speakers. The track lasts for 60 seconds and features a 2-second fade in and fade out.
Out-Of-Phase Brown Noise: Opposite-polarity brown noise signals in each channel. This track can be used to minimize the actual sound levels when breaking-in equipment, due to acoustic cancellation between the channels. The overall sound level will be minimized when two loudspeakers are placed as close together as possible.
Full Glide: This 300-second track contains a 285-second glide tone that sweeps from 5Hz to 20kHz, preceded by 5 seconds of silence and followed by 10 seconds of silence. Please be sure to play the entire track without interruption. Try it, you'll like it!
