Lindos Test CD1



Lindos Test CD1 This CD provides an accurate method for measuring the specifications of CD players. All tracks have been recorded at 15dB below digital full scale (FS) and this is referred to as the Alignment Level (AL) throughout the track listing below.

Each track has been dithered using TPDF (triangular probability density function) noise.

For more information on dither see "Quantization and Dither: A Theoretical Survey" Stanley Lipshitz, Robert Wannamaker, and John Vanderkooy published in the J. Audio Eng. Soc., Vol. 40, No. 5, 1992, pp. 355-375 (available from the AES).
