摘要： Described herein are systems and method for providing an immersive audio experience in a computer-generated virtual environment. An audio-mixer is placed at a location in a domain of the virtual environment and receives a separate audio feed from each of the audio source nodes directly connected to the audio-mixer. The audio-mixer mixes the received audio feeds in dependence on corresponding location, position and intrinsic loudness information to generate a separate spatialized mixed audio feed for each of the directly connected audio listener nodes. The audio-mixer sends, to each of the audio listener nodes directly connected to the audio-mixer, the separate spatialized mixed audio feed generated for the audio listener. An audio-mixer also receives and sends non-spatialized mixed audio feeds to/from other audio-mixers. The location of the audio-mixer is preferably moved to account for audio source nodes moving and/or changes to which audio source nodes are directly connected to the audio-mixer.

摘要： A system and method are disclosed for providing improved 3D sound experience to a user. The sound generation layer is customizable to allow the user and/or application provider to modify the internal rules the sound generation layer uses to render sounds, to amplify sounds that fall below a pre-set or user-set volume level, and to specifically amplify/soften certain sounds (such as game specific sounds like gunfire or footsteps), or specific frequencies of sounds. A graphical user interface can communicates with the sound generation layer to handle any or all the above, so that a lay user can easily adjust these settings without having to understand the underlying algorithms.

摘要： A data sonification method for representing multidimensional numerical information with a plurality of variable-timbre channels rendered in a sound field is described. The method includes generation of a plurality of variable-timbre audio waveforms, each having an audio frequency parameter and at least one timbre modulation parameter having an adjustable value that affects the timbre of the audio waveform. The method includes associating aspects of multidimensional numerical data with the timbre modulation parameter of each audio frequency waveform using a mapping element. The mapping element varies values of timbre modulation parameters responsive to selected values from the multidimensional numerical data. The method also positions each audio frequency waveform within a sonically-rendered sound field, associating aspects of multidimensional numerical data with the sonically-rendered position within the sound field. The sound field can be stereo, two-dimensional, or three-dimensional. The mapping element varies sonically-rendered positions responsive to selected values from the multidimensional numerical data.

摘要： The contents reproducing system includes a plurality of contents reproducing units, and the delay amount calculating unit calculates the delay amount with which each of the contents reproducing units reproduces the contents data. The delay amount is the time to delay the reproduction of the contents data, for example. The contents reproducing unit reproduces the contents data, by each of the contents reproducing units, with the delay based on the delay amount calculated by the delay amount calculating unit. By automatically controlling the delay amount of the contents data in this manner, the contents reproducing system can create a sound space with wrapped feeling and spreading feeling.

摘要： A grand piano generates acoustic tones through vibrations of strings and sound board so that the acoustic tones are converted to analog audio signals at recording points over the sound board, and a group of waveform data sets are produced from the analog audio signal through sampling and analog-to-digital conversion; when electronic tones are generated, delay parameters and volume parameters are determined on the basis of differences between the recording points and tone radiating points occupied by loud speakers, the sets of waveform data series are sequentially read out from the group of waveform data sets and are modified with the delay parameters and volume parameters so that the electronic tones become close to the acoustic tones.
