Systems and methods for generating a visual color display of audio-file data are provided. The system includes a processor that performs a method including receiving audio-file data; generating filtered-audio data by processing the audio-file data by frequency-band filters. The frequency band filters have different frequency bands. The method includes generating one or more waveforms corresponding to the filtered-audio data and displaying the waveforms superimposed in unique color relative to one another. The method includes downsampling the waveforms. The method includes processing the waveforms through an envelope detector. The method includes processing the waveforms through an expander and applying a gain factor. The waveforms have transparency levels at sections that are proportional or inversely proportional to amplitudes at the sections.

A system comprises one or more processors of a machine; a music player coupled to the one or more processors; and a memory storing instructions that, when executed by the one or more processors, cause the machine to perform operations. The operations comprise: electronically receiving a gait parameter; determining if the received gait parameter is less than a threshold; adjusting a music parameter if the received gait parameter is less than a threshold; and outputting the adjusted music with the music player.

A music reproduction program causes a computer to execute a graph setting step, a music selection step, and a reproduction step. The graph setting step sets a BPM graph showing the tempo of music file that a user listens to from the start of exercise to the end of exercise. The music selection step selects, when selecting the music file that the user listens to at any progress time in the distance or time after the start of the exercise, a music file having a BPM value within the predetermined range based on the BPM value at the progress time in the graph. The music selection step selects a music file having a BPM value within a predetermined range based on the BPM value set in the graph at the progress time point when reproduction of the entire music file is completed. The reproduction step reproduces the selected music file.

An automatic performing apparatus being an automatic performing apparatus that automatically performs performance data segmented into a plurality of performance sections, the apparatus includes: a first automatic performing unit configured to perform automatic performance of the performance data in a first performance section at a first tempo in response to an input of a first external event; and a second automatic per unit configured to, when a second external event is input before the automatic performance in the first performance section is finished, continue the automatic performance in the first performance section at a second tempo different from the first tempo, the second automatic performing unit configured to, when the automatic performance in the first performance section is finished, perform automatic performance of the performance data in a second performance section at a third tempo.

A musical score processing method that is realized by a computer includes receiving a control data related to displaying of a musical piece from a music processor that executes a process related to the musical piece and that is realized by a music processing program, using inter-application communication, based on a musical score processing program, and executing a display control process by displaying a musical score of the musical piece on a display device and controlling the displaying in accordance with the control data that has been received, based on the musical score processing program. The music processing program is separate from the musical score processing program.

The techniques disclosed herein enable a user of a host computer or a user of a remote computer to locate, view, control, and modify objects of a virtual environment. Embodiments disclosed herein can include the generation of a graphical user interface providing a two-dimensional display showing objects at a predetermined elevation of a three-dimensional virtual environment. User interface controls are provided for changing the elevation of the two-dimensional display. The two-dimensional display can be updated to show different elevations as the controls are used to select a new elevation. In some embodiments, the two-dimensional display enables users to move objects of a virtual reality environment. The display can bring highlight to select objects enabling users to readily locate desired objects and locations. The features disclosed herein can be utilized by a computer hosting a virtual reality session or a remote computer operating a companion application.

A DJ media player is provided. The DJ media player includes a display to show audio playback information; a platter used to control audio playback; one or more energy-storing devices; and a processor for responding to DJ media-player electrical-power loss. Responding to DJ media-player electrical-power loss includes storing electrical charge on energy-storing devices; sensing a disruption in electrical current supplied by a power source to the DJ media player; powering the DJ media player using the electrical charge on the energy-storing devices; and displaying a notification on a DJ media-player display that there was a disruption of power. Responding to electrical-power loss comprises performing a safe shutdown procedure for avoiding file and system corruption.

Techniques described herein enable administrative control features for hosted game applications. A user with appropriate credentials can override an administrator of a game application to control and view all aspects of a game session from a companion application operating on a remote computing device. The techniques disclosed herein enable a remote user with appropriate credentials to control and modify aspects of a game application or a game session. The features can include, but are not limited to, the ability to shape a 3D virtual environment, add players, remove players, modify possessions of players, call players to a beacon, modify attributes of an environment, locate items, and listen to player communication.

A data modification method of controlling sound , the method according to an embodiment includes providing a selection user interface that allows a user to select a modification mode to be applied to sound control data defining timing information of a sound generation from among a plurality of modification modes including a first modification mode and a second modification mode, modifying the sound control data by correcting the timing information and adding correction information according to an amount of correction of the timing information in a predetermined data section to the predetermined data section, in a state where the first modification mode is selected to be applied, and modifying the sound control data by correcting the timing information based on beat positions according to a predetermined tempo, in a state where the second modification mode is selected to be applied.

An audio playback device may be capable of operating in a shuffle mode in which audio or other content items are randomly selected. Environmental factor(s) such as ambient conditions or forces applied to the device or a peripheral can be used to identify one or more subsets of available content items from which content items are selected to thereby provide an ambient shuffle mode. By including or excluding items from the subset, the randomly-selected content items may more likely match the conditions under which the playback device is operating and/or match input provided by a user via tapping on, shaking, or otherwise applying force to the device or components in communication with the device.
