Auditory sense training method and sound processing method for auditory sense training

Abstract: An auditory sense training device 1 to be used in an auditory sense training method for training auditory sense by listening to a sound formed by processing an original sound comprises a band attenuation processing method 20 for attenuating a predetermined frequency band of an original sound 10, a switching means 30 for selectively outputting either the original sound or the output from said band attenuation processing means, a panpot processing means 40 for performing a panpot process wherein a voice signal formed by attenuating an original sound of one channel is superposed to the original sound of another channel, and a phase reverse processing means 50 for performing a phase reverse process of reversing the phase of the original sound, wherein a trainee listens to the original sound and a band attenuation processed sound formed by attenuating a predetermined frequency band of the original sound alternately.

Intelligent audio mixing among media playback and at least one other non-playback application

Abstract: In operation of an electronics device, audio based on asynchronous events, such as game playing, is intelligently combined with audio output nominally generated in a predictive manner, such as resulting from media playback. For example, an overall audio output signal for the electronic device may be generated such that, for at least one of audio channels corresponding to predictive manner processing, the generated audio output for that channel included into the overall audio output signal is based at least in part on configuration information associated with a processed audio output signal for at least one of the audio channels corresponding to asynchronous events based processing. Thus, for example, the game audio processing may control how audio effects from the game are combined with audio effects from media playback.

Binaural hearing aid

Abstract: This invention relates to a hearing enhancement system having an ear device for each of the wearer's ears, each ear device has a sound transducer, or microphone, and a sound reproducer, or speaker, and associated electronics for the microphone and speaker. Further, the electronic enhancement of the audio signals is performed at a remote digital signal processor (DSP) likely located in a body pack worn somewhere on the body by the user. There is a down-link from each ear device to the (DSP) and an up-link from the DSP to each ear device. The DSP digitally interactively processes the audio signals for each ear based on both of the audio signals received from each ear device. In other words, the enhancement of the audio signal for the left ear is based on the both the right and left audio signals received by the DSP. In addition digital filters implemented at the DSP have a linear phase response so that time relationships at different frequencies are preserved. The digital filters have a magnitude and phase response to compensate for phase distortions due to analog filters in the signal path and due to the resonances and nulls of the ear canal.

Multi-scene recording medium and apparatus for reproducing data therefrom

Abstract: A multi-scene recording disk and a data reproducing apparatus which enables a user to select and enjoy one of simultaneously proceeding scenes, and also enables a program editor to edit programs using a new concept and novel fashion. Related program movements, each consisting of program bars, are recorded on the disk 100. The data reproducing apparatus includes a data string processing section 203, a system control section 204, an operator panel 205, a video processing section 206, and audio processing sections 211 and 213. The sections 203 and 204 and the panel 205 select any one of the program movements and switch one movement to another, and select any one of the program bars of the movement selected and switch one bar to another. The information thus selected is supplied to the video processing section 206 and the audio processing sections 211 and 213.
