Abstract: Systems and methods for generating a graphical representation of audio signal data during time compression or expansion are provided. The system may include a processor that performs a method including displaying a waveform during audio-signal playback at a first speed by scrolling the waveform from aright portion of a display to a left portion of the display. The method includes receiving a command to increase or decrease the audio-signal playback speed and horizontally expanding or horizontally contracting the waveform in response to receiving the command to increase or decrease the audio-signal playback speed.

Abstract: Systems and methods for generating a playback-information display during time compression or expansion of an audio signal are provided. The system includes a processor that performs a method including displaying a first remaining playback-time associated with an audio file; adjusting the playback speed of the audio file during playback of the audio file; and, in response to the playback speed being adjusted, automatically displaying a second remaining playback-time associated with the audio file during playback of the audio file.

Abstract: Systems and methods for selecting an audio track by performing a gesture on a track-list image are provided. The system includes a processor that performs a method including displaying the audio-track list, detecting a contact with the touchscreen display at a location corresponding to the audio track, detecting a continuous movement of the contact in a direction, detecting a length of the continuous movement, and selecting the audio track if the continuous movement has a length longer than a threshold length. The method includes shifting text associated with the audio track based on the length and direction of the continuous movement. The method includes determining that the selection is a command to queue the audio track for playback or add it to a preparation track list. This determination may be based on the direction of the continuous movement.

Abstract: A standalone DJ console includes onboard audio data, user interface, processing engine and mixing module that enable multiple virtual audio players operating under the control of the processor to be mixed by virtual mixing processes into two different audio signal streams routable to different outputs of the console to provide two different audio streams to two separate spaces. The user interface is designed with a virtual display and parallel sets of controls which enable virtual representations of audio waveforms to be scrolled relative to an axis of time above the respective set of controllers used to manipulate the audio signal stream.

Abstract: A DJ media player is provided. The DJ media player has a control wheel used to control audio playback and a customizable first electronic display located about the center of the platter for displaying a graphic. The DJ media player has a second electronic display to show audio playback information. The graphic is dynamically updated. The graphic corresponds to at least one of a logo, an artist, an album, a song playback information, or a selection made by a user.
