One embodiment provides a system, method, and device for communicating inaudible tones. An audio file is received. One or more inaudible tones are embedded in the audio file. The information is associated with the inaudible tones. The audio file is distributed with the embedded one or more inaudible tones.

Musical attribution is performed in a two-dimensional (2D) digital representation. A piece of music representing a musical score is inputted. An abstracted representation of blanks of the score, called a digital audio canvas, is produced. Interactive, dynamic attribution is performed by a user to bring to life the musical score of abstracted blanks. Instrumentation selection, relative volume, scale selection, and score tempo are all musical attributes that are conveyed to the score of abstracted blanks. The score of the digital audio canvas is played back using the attributed blanks. The playback of the score is enabled by selecting appropriate abstracted blanks. The appropriate abstracted blanks are included among other blanks for increased educational and enjoyment value. The modified score is converted back into the format of the original inputted piece of music.

A low-cost and high-compatibility optical pickup including a light source, one set of optical sensors, and a controller. The light source illuminates a string assembled on an instrument. The set of optical sensors corresponding to the light source is provided to sense the shading of the string. The controller supplies the sensed data from the set of optical sensors to a system host for recognition of the melody played on the string. Considering the other strings assembled on the instrument, the optical pickup includes other sets of optical sensors to sense the shading of the other strings which are also illuminated by the light source. The controller also supplies the sensed data of the other sets of optical sensors to the system host for recognition of the melody played on the other strings.

Methods are provided for enabling audience members at a live or substantially live performance to interact with performers and participate in the performance.

Disclosed is a method for performing a musical score, the method comprising generating a plurality of score maps using at least one of an electronic representation of the musical score and event-based notations for at least one musical note in the musical score, wherein each score map corresponds to a single performance characteristic of the musical score and contains a plurality of events related to the single performance characteristic, and wherein each of the plurality of score maps is processed by a processing block to generate a plurality of playback characteristic maps.

A digital audio workstation organizes musical information in a visually consistent manner, such that it is easier for the user to see and to manipulate the content in a song. The organization includes a multitrack music stream, which depicts multiple adjacent streams (or tracks) of musical content playing in parallel; a Play Bar, which is a visual plane intersecting the music stream; and two or more data layers, which are spatially aligned with the underlying musical stream, but each of which contains a specific type of musical data which can be viewed and manipulated in isolation. This approach to visual organization of music information has some major benefits to the user. Many different kinds of musical content and transformations can be depicted in a clear and consistent manner, making it easier for the user to see and manipulate the song.

A display control method includes causing a display device to display a processing image in which a first image representing a note corresponding to a synthesized sound and a second image representing a sound effect are arranged in an area, in which a pitch axis and a time axis are set, in accordance with synthesis data that specify the synthesized sound generated by sound synthesis and the sound effect added to the synthesized sound.

An automatic performance system includes a sign detector configured to detect a sign action of a performer performing a musical piece, a performance analyzer configured to sequentially estimates a performance position in the musical piece by analyzing an acoustic signal representing performed sound in parallel with the performance, and a performance controller configured to control an automatic performance device to carry out an automatic performance of the musical piece so that the automatic performance is synchronized with the sign action detected by the sign detector and a progress of the performance position estimated by the performance analyzer.

Presented herein are systems and methods for presenting content of an electronic book to provide real-time feedback to a user performing a musical piece, and to select content for subsequent presentation to the user based at least in part on an automated assessment of user performance of the musical piece.

One embodiment provides a system, method, and device for capturing inaudible tones from music. A song is received. Inaudible tones are detected in the song. Information associated with the inaudible tones is extracted from the song. The information associated with the inaudible tones is communicated to a user.
