Abstract: The invention is a system for recording and reading both program data and acoustical control data and playing back the data to optimize performance of audio reproduction and recreate the effect of an original acoustic environment. The system has a recording apparatus, a playback apparatus and a recording media. The recording apparatus produces recording media having both acoustic control information and audio data. The playback apparatus gives the user some ability to override otherwise automatic parameter adjustments. Optionally, a metadata display system takes information about the physical arrangement of instruments and other characteristics of the recording session and the recording studio and makes that visually available to the listener. A player type register identifies the characteristics of the playback device to cause an adjustment of the characteristics of the playback system.

Abstract: Methods and apparatus for recording on DVD-like recording media in which audio content is stored in a high-capacity multi-channel (e.g., six-channel) format are provided. Various channels may use various resolutions. A two-channel audio output may be derived from the multi-channel audio data stream during playback. To facilitate an accurate derivation, the mixing coefficients to be used in generating the derivation can be supplied along with the six-channel audio data.

Abstract: An improved sock with a circumferential flap secured thereto which when worn in combination with footwear, prevents the introduction of foreign particulate such as pebbles into the hiking boots and other footwear. The sock is made from cotton, wool, synthetic material or a combination thereof. The flap is preferably made from a material that is liquid impermeable and is vapor permeable. The flap is secured to the sock by looming, stitching, buttons, or by complimentary materials on both the flap and the sock. In operation, the flap is lowered to a position where it circumferentially covers the top of the shoe or hiking boot thereby preventing environmental hazards from entering therein. In some embodiments, additional means are used to secure the flap to the footwear such as VELCRO, buttons, and a drawstring.

Abstract: Methods and apparatus for recording and playing back multi-channel digital audio having different sampling rates for different channels are provided. Recording is accomplished by sampling a plurality of channels of audio data and arranging the samples of the plurality of channels of audio data in most nearly the order needed during playback. Playback is accomplished by accessing the samples of the plurality of channels of audio data and converting the samples from digital to analog form. The playback may include deriving audio signals in a different format from the format in which the programming is recorded.
