摘要： A sound enhancement system (SES) that can enhance reproduction of sound emitted by headphones and other sound systems. The SES improves sound reproduction by simulating a desired sound system without including unwanted artifacts typically associated with simulations of sound systems. The SES facilitates such improvements by transforming sound system outputs through a set of one or more sum and cross filters, where such filters have been derived from a database of known direct and indirect head-related transfer functions (HRTFs).

摘要： A system for headphone equalization includes a stored set of predetermined tone burst reference signals and a stored set of predetermined tone burst test signals that form a range of frequencies used in a user specific audio test to develop a headphone correction filter. A predetermined tone burst reference signal and a predetermined tone burst test signal may intermittently and sequentially drive a transducer included in the headphone. A loudness of the predetermined tone burst reference signal may be fixed and a loudness of the predetermined tone burst test signal may be variable with a gain setting. The gain setting may be used to generate the headphone correction filter.

摘要： A frequency equalization system is provided that substantially equalizes the room frequency responses generated by at least one loudspeaker within a listening area so that the frequency responses in the listening area are substantially constant and flat within a desired frequency range with minimum signal latency. The frequency equalization system may use multiple microphones to measure the audio signals of one or more subwoofers to achieve an improved bass response that is flat across the relevant frequency range. The system employs an algorithm that is a closed-form, non-iterative, mathematical solution and features short computation time with reduced delays.

摘要： A portable audio enhancement device is configured for enhancing audio signals, and may be utilized in an audio system. The audio system may include a portable audio source, the audio enhancement device, an audio playback device, and a loudspeaker. The audio enhancement device receives audio signals from the audio source and produces enhanced audio signals. The audio playback device receives the enhanced audio signals and outputs the enhanced audio signals to the loudspeaker for playback. Enhancement of the audio signals may be based on an analysis performed by the audio enhancement device by measuring sample audio signals derived from the sound outputted from the loudspeaker.
