ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of digital representation of music and to techniques for allowing a user to enter a selection of a realization of the music.
BACKGROUND AND PRIOR ART
Most of today's audio data, at the professional as well as at the consumer level, is distributed and stored in digital format. This has greatly improved the general handling of recorded audio material, such as transmission of audio files and modification of audio files.
Techniques for navigating among audio data files have been developed. For example a track number and time is used as a navigation means for compact discs (CDs). A variety of more sophisticated techniques for navigating among the program segments and to otherwise process audio files is known from the prior art:
U.S. Pat. No. 6,199,076 shows an audio program player including a dynamic program selection controller. This includes a playback unit at the subscriber location to reproduce the program segments received from a host and a mechanism for interactively navigating among the program segments.
U.S. Pat. No. 5,393,926, is a virtual music system. There is included a multi-element actuator that generates a plurality of signals in response to being played by a user. The system also has an audio synthesizer that generates audio tones in response to control signals. There is a memory storing a musical score for the multi-element actuator, the stored musical score including a sequence of lead notes and an associated sequence of harmony note arrays. Each harmony note array of the sequence corresponding to a different one of the lead notes and contain zero, one or more harmony notes. The instrument also includes a digital processor receiving the plurality of signals from the multi-element actuator and generating a first set of control signals therefrom. The digital processor is programmed to identify from among the sequence of lead notes in the stored musical score a lead note which corresponds to a first one of the plurality of signals. The digital processor is also programmed to map a set of the remainder of the plurality of signals to whatever harmony notes are associated with the selected lead note, if any. Moreover, the digital processor is programmed to produce the first set of control signals from the identified lead note and the harmony notes to which the signals of the plurality of signals are mapped. The first set of control signals causes the synthesizer to generate sounds representing the identified lead note and the mapped harmony notes.
U.S. Pat. No. 5,390,138, is a system for connecting an audio object to various multimedia objects to enable an object-oriented simulation of a multimedia presentation using a computer with a storage and a display. A plurality of multimedia objects are created on the display including at least one connection object and at least one audio object. Multimedia objects are displayed, including at least one audio object. The multimedia object and the audio object create a multimedia presentation.
U.S. Pat. No. 5,388,264, is a system for connecting a Musical Instrument Digital Interface (MIDI) object to various multimedia objects to enable an object-oriented simulation of a multimedia presentation using a computer with a storage and a display. A plurality of multimedia objects are created on the display including at least one connection object and at least one MIDI object in the storage. The multimedia object and the MIDI object are connected, and information is routed there between to create a multimedia presentation.
U.S. Pat. No. 5,317,732 is a process performed in a data processing system that includes receiving an input selecting one of a plurality of multimedia presentations to be relocated from a first memory to a second memory, scanning the linked data structures of the selected multimedia presentation to recognize a plurality of resources corresponding to the selected multimedia presentation, and generating a list of names and locations within the selected multimedia presentation corresponding to the identified plurality of resources. The process also includes renaming the names on the generated list, changing the names of the identified plurality of resources in the selected multimedia presentation to the new names on the generated list, and moving the selected multimedia presentation and the resources identified on the generated list to the second memory.
U.S. Pat. No. 5,262,940 is a portable audio/audio-visual media tracking device.
U.S. Pat. No. 5,247,126, is an image reproducing apparatus, image information recording medium, and musical accompaniment playing apparatus.
U.S. Pat. No. 5,208,421, is a method and apparatus for audio editing of MIDI files. The invention may be utilized to ensure the integrity of a source MIDI file, a copied or lifted section or a target file by automatically inserting matching note on or note off messages into a file or file section to correct inconsistencies created by such editing. Additionally, program status messages are automatically inserted into source files, copied or lifted sections, or target files to yield results that are consistent with the results that may be obtained by editing digital audio data. Timing information is selectively added or maintained such that MIDI files may be selectively edited without requiring a user to learn a complex MIDI sequencer.
U.S. Pat. No. 5,153,829, is an information processing apparatus. The invention has a unit for displaying on a screen a musical score, keyboard, and tone time information to be inputted. There is also a unit for designating the position of the keyboard, and tone time information, respectively displayed on the display unit. Moreover, the invention includes a unit for storing musical information produced through designation by the designating unit of the position of the keyboard and tone time information displayed on the display unit. Additionally, there is a unit for controlling the display of the musical score, keyboard, and tone time information on the screen of the display unit. The unit also is for controlling the display of a pattern of musical tone or rest on the musical score on the display unit in accordance with the position of the keyboard and tome time information respectively designated by the designating unit. Finally, there is a unit for generating a musical tone by reading the musical information stored in the storage unit.
U.S. Pat. No. 5,142,961, is a method for storage, transcription, manipulation and reproduction of music on system-controlled musical instruments which faithfully reproduces the characteristics of acoustic musical instruments. The system comprises a music source, a central processing unit (CPU) and a CPU-controlled plurality of instrument transducers in the form of any number of acoustic or acoustic hybrid instruments. In one embodiment, performance information is sent from a music source MIDI controller to the CPU, edited in the CPU, converted into an electrical signal, and sent to instrument transducers via transducer drivers. In another embodiment, individual performances stored in a digital or sound tape medium are reproduced at will through the instrument transducers, or converted into MIDI data by a pitch/frequency detection device for storage, editing or performance in the CPU. In still another embodiment, performance information is extracted from an electronic recording medium or live performance by a pitch/frequency detection device, edited in the CPU, converted into an electrical signal, and sent to any number of instrument transducers. The device also eliminates typical acoustic musical instrument delay problems.
U.S. Pat. No. 5,083,491, is a method and apparatus for re-creating expression effects on solenoid actuated music producing instruments contained in musical renditions recorded in MIDI format for reproduction on solenoid actuated player piano systems. Detected strike velocity information contained in the MIDI recording is decoded and correlated to strike maps stored in a controlling microprocessor. The str
