摘要： A remastering system may up-convert the sample rate of an input sampled value digital program signal (DPS), generate harmonics of the up-converted signal at the sample rate of the up-converted signal, add the harmonics to the up-converted signal, and filter the resulting signal to produce a remastered signal having enhanced content compared to the original signal. The remastering system may further include a frequency-specific time alignment corrector and equalizer that delays lower frequencies of the input signal with respect to higher frequencies of the input signal to produce an alignment of signal components that is truer to the original recorded sound. The source of the input signal may be an audio CD.
