20120106747 | System and Method for Automatic Selection of Audio Configuration Settings - In one embodiment the present invention includes a circuit for automatically adjusting an output of an audio device. The circuit includes a memory circuit, a detector circuit, a control circuit, and an output circuit. The memory circuit stores configuration information. The detector circuit detects environment information related to an environment in which the apparatus is present. The control circuit selects selected configuration information from the memory circuit according to the environment information detected by the detector circuit. The output circuit receives an input audio signal and the selected configuration information, modifies the input audio signal according to the selected configuration information, and generates an output audio signal corresponding to the input audio signal as modified according to the selected configuration information. | 05-03-2012 |
20130013096 | Techniques for Distortion Reducing Multi-Band Compressor with Timbre Preservation - Distortion reducing multi-band compressor with timbre preservation is provided. Timbre preservation is achieved by determining a time-varying threshold in each of a plurality frequency bands as a function of a respective fixed threshold for the frequency band and, at least in part, an audio signal level and a fixed threshold outside such frequency band. If a particular frequency band receives significant gain reduction due to being above or approaching its fixed threshold, then a time-varying threshold of one or more other frequency bands are also decreased to receive some gain reduction. In a specific embodiment, time-varying thresholds can be computed from an average difference of the audio input signal in each frequency band and its respective fixed threshold. | 01-10-2013 |
