  • Patent number: 11894006
    Abstract: The processing of audio signals during playback is provided, so that audio signals that fall below a specified threshold loudness level are processed to avoid making unwanted background noise audible. N-channel audio is received from a playback volume controller/leveler (101). The level of the audio is compared with a threshold level. If the level is greater than the threshold level, the audio is processed with a first amount of gain in accordance with a first dynamic range control (DRC) compression curve that is tuned for professionally produced audio. If the level is less than or equal to the threshold level, the audio is processed with a second amount of gain in accordance with a second DRC compression curve that is designed to avoid boosting unwanted background noise. After applying the gain to the audio, the audio is sent to a downstream device.

  • Patent number: 7949141
    Abstract: A method, an apparatus, and a software product to process a plurality of input audio signals. The apparatus accepts a plurality of input signals and includes a multi-input, multi-output reverberator arranged to generate a set of output signals including delayed reverberation components simulating the reverberations a listener is likely to hear in a listening environment. The apparatus further includes a multi-input, two-output filter accepting the outputs of the reverberator and the plurality of input terminals, providing outputs for the left and right ears, and configured to implement a set of head related transfer functions corresponding to a listening environment and a set of directions of a listener in the listening environment.

  • Patent number: 7539319
    Abstract: An apparatus for creating, utilizing a pair of oppositely opposed headphone speakers, the sensation of a sound source being spatially distant from the area between the pair of headphones, the apparatus comprising: (a) a series of audio inputs representing audio signals being projected from an idealised sound source located at a spatial location relative to the idealised listener; (b) a first mixing matrix means interconnected to the audio inputs and a series of feedback inputs for outputting a predetermined combination of the audio inputs as intermediate output signals; (c) a filter system of filtering the intermediate output signals and outputting filtered intermediate output signals and the series of feedback inputs, the filter system including separate filters for filtering the direct response and short time response and an approximation to the reverberant response, in addition to the feedback response filtering for producing the feedback inputs; and (d) a second matrix mixing means combining the filtered

  • Patent number: 7447722
    Abstract: A method for applying a computation utilizing a processor (112) capable of accessing an on-chip memory (114) and data from an off-chip source (116), the method comprising the iterative steps of retrieving at the on-chip memory (114) successive frames of input data from the off-chip source (116); computing from a current input frame of data (30) available in the on-chip memory current result elements for completing a current output frame of results (33, 34, 35), and pre-computing from the current frame of input data future result elements for contributing to at least one future output frame of results.

  • Patent number: 6741706
    Abstract: A method of processing a series of input audio signals representing a series of virtual audio sound sources placed at predetermined positions around a listener to produce a reduced set of audio output signals for playback over speaker devices placed around a listener, the method comprising the steps of: (a) for each of the input audio signals and for each of the audio output signals: (i) convolving the input audio signals with an initial head portion of a corresponding impulse response mapping substantially the initial sound and early reflections for an impulse response of a corresponding virtual audio source to a corresponding speaker device so as to form a series of initial responses; (b) for each of the input audio signals and for each of the audio output signals: (i) forming a combined mix from the audio input signals; and (ii) forming a combined convolution tail from the tails of the corresponding impulse responses; (iii) convolving the combined mix with the combined convolution tail to form a combined t

  • Patent number: 6421697
    Abstract: A method of performing a convolution of an input data stream, the method comprising the steps of: (a) transforming an initial series of input data values into the frequency domain to form initial frequency domain data values; (b) multiplying the frequency domain data values with a set of coefficients so as to form convolved frequency data; (c) transforming the convolved frequency data into a spatial domain so as to form an initial series of output data values; (d) performing steps (a) to (c) on a subsequent series of input data values of the input data stream so as to form a subsequent series of output data values; the subsequent series of input data values overlapping the initial series of input data values; and (e) cross fading overlapping portions of the initial and subsequent output data values.
