Technical Examples
- The present invention provides a music playback system which uses an interface to easily play back a characteristic musical structure section with a music audio data playback apparatus. The interface 13 includes a function of selecting an arbitrary characteristic music structure section from a plurality of characteristic music structure sections, and a function of visualizing a characteristic music structure section. The characteristic music structure section specifying data for specifying the selected arbitrary characteristic music structure section is given to a music audio data playback apparatus 3. The music audio data playback apparatus 3 changes a playback position of the music audio data to the characteristic music structure section specified by the characteristic music structure section specifying data given by a specifying data providing means 12.
- The present invention provides an information recording medium in which at least one set of an audio data portion and a music block, which represent a piece of music, is recorded. The audio data portion includes first audio data. The music block includes first music reproduction information associated with the first audio data so as to manage reproduction of the first audio data. The first music reproduction information includes a first block type which indicates that the first audio data is audio data for a first use.
- A recording and reproducing system is broken down into a recording unit for producing a digital audio data signal from MIDI music data words asynchronously produced at irregular intervals and a playback unit for reproducing the MIDI music data codes from the digital audio data signal, wherein synchronous data nibbles are supplemented in the irregular intervals among the MIDI music data words for producing a data stream, and the digital audio data signal is produced from the data stream through a differential phase shift keying and a phase code modulation so as to record the MIDI messages in a digital versatile disk at high dense.
- A method and a plant for simultaneous production of a gas for injection into an oil field and production of methanol, dimethyl ether and/or other oxygenated hydrocarbons or production of higher hydrocarbons from natural gas is disclosed. An air separation unit (ATR) for production of pure nitrogen for injection and pure oxygen for production of synthesis gas ("syngas") by authermal reformation of a natural gas is an essential part of the method and plant.
- Music and non-music portions in an audio stream are identified. The audio stream is digitized and segmented into frames. Selected frames are passed through a filter bank which includes filters having bandwidths approximately proportional to their center frequencies. The spectral flux for each selected frame is calculated and smoothed. Frames having a smoothed spectral flux below a threshold value are associated with music, and frames having a smoothed spectral flux above a threshold value are associated with non-music.
