A system for audibly conveying financial information using a computerized system. The system receives financial information includes a variable parameter which varies over a time period. The at least one processor associates the received financial data with a musical instrument. It also determines, for a plurality of values of the variable parameter during a time period, a plurality of musical notes based on the values of the variable parameter, and generates audio data associated with the plurality of musical notes corresponding to the changes in the variable parameter. When the processor determines whether any of the plurality of generated musical notes for the associated musical instrument are at the highest or lowest range, and automatically readjust the tonal range of the musical notes or changes the associated musical instrument. The system-generated audio data is audibly reproduced in musical notes of the associated musical instrument.

Systems, methods and apparatus for cellular compositions/generating music in real-time using cells are provided. The cellular compositions may be dependent on user data.

A virtual instrument for real-time musical generation includes a musical rule set unit for defining musical rules, a time constrained pitch generator for synchronizing generated music, an audio generator for generating audio signals, wherein the rule definitions describe real-time morphable music parameters, and said morphable music parameters are controllable directly by the real-time control signal. With this virtual instrument, the user can create new musical content in a simple and interactive way regardless of the level of musical training obtained before using the instrument.

Computer-based systems, devices, and methods for generating musical compositions are described. A population of musical compositions stored in digital media are each segmented to produce abridged samples. The samples are analyzed to identify parent compositions that best exhibit or evoke a particular desired quality. The parent compositions are cross-bred to generate a set of child compositions which are similarly segmented and analyzed. The child compositions that best exhibit or evoke the particular desired quality are re-cast as parent compositions from which another generation of child compositions are bred. Mutations in the form of musical variations are inserted in at least some iterations and the process is repeated until at least one child composition that satisfies some exit criterion is returned.

A social entertainment user interface operating on a wireless networked record session device capable of producing a live video and/or audio stream as if made in a vintage record booth. Record sessions are listened to and/or watched by a plurality of other social entertainment user interfaces operating on other networked listening/watching wireless networked devices. Video and audio filters emulate various altered looks and sounds. Record sessions are streamed live or near-live for other social entertainment user interfaces operating on other networked wireless devices to listen and/or watch, and passively and actively rated to dynamically enable watching of the most preferred record sessions.

A method and a device provides a user with the ability to freely improvise or play around with a selection of different chords and be provided with visual guidance assisting the improvisation of melody, while also providing accompaniment consistent with the selection of chords. Sound files consistent with a user selection of a chord and/or a dynamic level are selected from an audio library and played, while the user is given visual cues on a user interface keyboard assisting the user to select notes that are consistent with the chord selected for the accompaniment.

A music composition system for composing music segments comprises: a computer interface comprising at least one external input for receiving from an external device a request for a musical composition; a controller configured to determine based on a request received at the external input a plurality of musical parts for the musical composition; and a composition engine configured to generate, for each of the determined musical parts, at least one musical segment in digital musical notation format, the musical segments configured to cooperate musically when performed simultaneously. The computer interface comprises at least one external output configured to output a response to the request, the request comprising or indicating each of the musical segments in digital musical notation format for rendering into audio data at the external device.

An adaptive music playback system is disclosed. The system includes a composition system that receives information corresponding to user activity levels. The composition system modifies the composition of a song in response to changes in user activity. The modifications are made according to a set of composition rules to facilitate smooth musical transitions.

A method comprises obtaining a playlist that comprises a plurality of audio items, and dividing the playlist into a plurality of coherent groups, wherein each coherent group comprises a respective sequence of audio items of the plurality of audio items with a common attribute. For a respective coherent group of the plurality of coherent groups, the method comprises determining a parameter value of a first audio item of the respective sequence and adjusting a parameter value of a second audio item of the respective sequence based on the determined parameter value of the first audio item, to form a transition between the first and second audio items. The first and second audio items are adjacent in the respective sequence. The transition is provided to a second electronic device for playback.

Audio mix information is received from a plurality of users. Mix rules are determined from the audio mix information from the plurality of users, wherein the mix rules include a first mix rule associated with a first audio item. The first mix rule relates to an overlap of the first audio item with another audio item. The first mix rule is made available to one or more clients. After making the first mix rule available, an indication, from a respective client device, that the first audio item is to be mixed with a second audio item at the respective client device in accordance with the first mix rule is received. In response to the indication, a specification of the first mix rule is transmitted to the respective client device to be applied by the respective client device to generate a transition between the first audio item and the second item.
