摘要： An audio system installed in a listening space may include a signal processor and a plurality of loudspeakers. The audio system may be tuned with an automated audio tuning system to optimize the sound output of the loudspeakers within the listening space. The automated audio tuning system may provide automated processing to determine at least one of a plurality of settings, such as channel equalization settings, delay settings, gain settings, crossover settings, bass optimization settings and group equalization settings. The settings may be generated by the automated audio tuning system based on an audio response produced by the loudspeakers in the audio system. The automated tuning system may generate simulations of the application of settings to the audio response to optimize tuning.

摘要： An automotive audio controller is provided for receiving an audio signal from an audio source and providing a filtered audio signal that may help compensate for ambient noise in the automobile. The audio controller may have a vibration sensor that generates a vibration signal indicative of vibrations in the automobile. A dynamic filter of the audio controller may receive the vibration signal and the audio signal, and change the gain level and/or tone of the audio signal based on the vibration signal to generate the filtered audio signal. The audio controller also may receive a speed signal, and change the gain level and/or tone of the audio signal based on the speed signal to generate the filtered audio signal.

摘要： A sound processing system adaptively mixes active matrix decoding and passive matrix processing of incoming audio signals. Mixed output signals are generated with active matrix decoding where the audio signals are stereo. Mixed output signals are generated with passive matrix processing where the audio signals are monaural. The sound processing system reduces the degree of active matrix decoding in the mixed output signals where the incoming audio signals are stereo and monaural. The sound processing system also generates virtual stereo signals from incoming audio signals having monaural signals. Mixed output signals are generated of the virtual stereo signals using active matrix decoding.

摘要： A sound processing system for a vehicle includes a sound processor that is configured to mix at least one real audio input signal to form at least one virtual output signal. At least one audio signal that is available to drive at least one loudspeaker may be formed using the combination of the virtual output signal and the real audio input signal. The virtual output signal may be post processed to form a predetermined frequency range of the audio signal prior to being combined with the real audio input signal. The audio signal may be created by mixing the real audio input signal with the post processed virtual output signal. Alternatively, the audio signal may be formed by mixing the real audio input signal to form a real audio output signal, and then summing the real audio output signal with the post processed virtual output signal. Mixing may be performed with a crossbar mixer included in the sound processor.

摘要： A sound processing system reduces the instances when only a center speaker is heard. The gain of a volume setting is adjusted for individual speakers in response to one or more input signals. The gain of the center speaker is attenuated in relation to the global volume setting. In addition or as an alternative, the gain of front and/or rear speakers is increased. A virtual center channel is generated for locations where the center speaker may not be heard.

摘要： A digital sound processing design system for a vehicle audio system includes a computer and a design tool that is run by the computer. The design tool allows a user to define sound processing criteria that is stored in a template file. An audio signal processor is connected to the first and second real channel inputs of an audio source. Memory that is coupled to the audio signal processor stores the template file. The sound processing engine that is coupled to the audio signal processor and the memory reads the template file at run-time to obtain the sound processing criteria. The sound processing engine applies the sound processing criteria to the first and second real channel inputs. The design tool allows a user to create virtual channel inputs and outputs that are based, in part, on the first and second real channel inputs.

摘要： A fault tolerant liquid measurement system includes a plurality of sensors for measuring parameters of a liquid in a container; each sensor generating a measurement signal representative of the liquid parameter measured thereby. The sensors are grouped into a number of sets, each set including some sensors of another set. The measurement signals of each set of sensors are processed in a processor to determine for each set of sensors a first estimate signal representative of a likelihood of measurement signal validity for the measurement signals of the corresponding set, and a second estimate signal representative of liquid quantity in the container based on the measurement signals of the corresponding set. The processor further determines a third estimate signal of liquid quantity in the container based on a function of the first and second estimate signals.
