Systems and methods for generating a graphical representation of audio-file playback during playback manipulation

A system comprising a processor and a non-transitory computer-readable storage medium storing instruction that, when executed by the processor, cause the processor to perform a method, the method comprising:

• displaying a waveform during audio-file playback, wherein displaying the waveform during the audio-file playback comprises scrolling the waveform from a first portion of a display to a second portion of the display;
• receiving a command to manipulate the audio-file playback;
• displaying a first half of the waveform corresponding to the manipulated audio-file playback until a command is received to resume the audio-file playback, wherein the first half of the waveform is a portion of the waveform adjacent to a horizontal or vertical axis;
• and
• simultaneously displaying a second half of the waveform and displaying the first half of the waveform corresponding to the manipulated audio-file playback, wherein the second half of the waveform is on an opposite side of the horizontal or vertical axis from the first half of the waveform.

A DJ media player comprising:

• a display to show audio playback information;
• a processor for displaying an audio-file waveform on a DJ media player, wherein displaying an audio-file waveform comprises:
• displaying a waveform during audio-file playback, wherein displaying the waveform during the audio-file playback comprises scrolling the waveform from a right portion of a display to a left portion of the display;
• receiving a command to manipulate the audio-file playback;
• displaying a first half of the waveform corresponding to the manipulated audio-file playback until a command is received to resume the audio-file playback, wherein the first half of the waveform is a portion of the waveform above or below a horizontal axis;
• and
• simultaneously displaying a second half of the waveform and displaying the first half of the waveform corresponding to the manipulated audio-file playback, wherein the second half of the waveform is on an opposite side of the horizontal axis from the first half of the waveform.
