Abstract: An audio processing apparatus for modifying a primary audio signal includes a modulator that increases or decreases a level of a noise signal generated by a noise generator, in response to an increase or a decrease of a detected signal level of the primary audio signal, to generate a modulated noise signal. The apparatus further includes a combiner that combines the primary audio signal and the modulated noise signal. The modulator operates, with respect to a signal delayer, to time-advance a decrease in the level of said noise signal based on a corresponding decrease in the signal level of the primary audio signal.

The digital audio signal is compressed and encrypted without substantial impairment to produce a first audio signal. A second, unencrypted, audio signal is produced. The first and second audio signals are combined. Preferably the first audio signal is losslessy compressed. The second audio signal may be an impaired version of the original digital audio signal.
