  • Method for independent dynamic range control
    Patent number: 6785655
    Abstract: Different dynamic range control values are applied to the 2-channel and m-channel outputs without repeating the inverse transform or the windowing of the audio samples. First, m-channel dynamic range control values are applied to audio samples in the frequency domain (“frequency samples” or “frequency coefficients”). The frequency samples are then inverse transformed to generate audio samples in the time domain (“time samples”) and windowed to generate windowed time samples. The windowed time samples are saved and the 2-channel dynamic range control values are applied to the windowed time samples. 2-channel dynamic range control values include 2-channel scale factors that, when multiplied with groups of the windowed time samples, at least partially remove the effects of windowing and the m-ch dynamic range control values applied in the frequency domain and readjust the dynamic range for 2-channel output.

  • Method for independent dynamic range control
    Patent number: 6782366
    Abstract: Different dynamic range control values are applied to the 2-channel and m-channel outputs without repeating the inverse transform of the audio samples. First, m-channel dynamic range control values are applied to audio samples in the frequency domain (“frequency samples” or “frequency coefficients”). The frequency samples are then inverse transformed to generate audio samples in the time domain (“time samples”). The time samples are duplicated to two sets where the 2-channel dynamic range control values are applied to one set of time samples. 2-channel dynamic range control values include 2-channel final scales that, when multiplied with the first set of time samples, at least partially remove the effects of the m-channel dynamic range control and readjust the dynamic range for 2-channel output. The first set and the second set are then windowed.
