  • Mixing system 14 audibly combines two or more audio clips together as a mixed audio track.
  • the audio clips may be retrieved from memory 16 and/or received directly from input system 12.
  • Mixing system 14 may mix an unedited clip stored in memory and/or a clip that has been edited, such as by editing system 18. Clips may be mixed in their entirety, or selected portions of the clips may be audibly combined together.
  • a mixed track may be selected for playback as a single entity. During playback, a mixed track plays the selected portions as determined by the linkage established during mixing. A mixed track may also be saved into memory 16 for later playback and or sharing. In some embodiments a mixed track may include a data file with instructions detailing how to combine two or more clips.
  • the mixing system may be used to create a realtime mix, in which the output system plays the mixed track while the mix is being produced by a user. In such embodiments, the mixed track may be saved into memory, although this is not required.
  • Mixed tracks may be arranged so that the constituent audio clips are arranged as a layered track, in which selected portions of two or more tracks are arranged for simultaneous playback, and/or as a linear track, in which a portion of one clip follows a portion of another clip.
  • Mixed tracks may also include looped portions, in which the same segment of audio content is repeated two or more times.
  • a produced track may include linear, layered, and looped portions.
  • the relative volume of the constituent clips may be automatically adjusted and/or manually adjusted. For example, the output level of two or more clips may be automatically matched or a user may adjust a clip's volume using a fader or other suitable control.
  • Mixing system 14 may synchronize the beat of two or more clips so that the respective beats from the clips automatically synchronize with one another.
  • the mixing system may automatically adjust the tempo of a clip to correspond with the tempo of another clip when mixing the clips into a produced track.
  • Such synchronization may facilitate an illusion that a mixed track is professionally produced, resulting in high-quality audio content.
  • tempo synchronization may be used to combine the clips in a sonically pleasing manner, which would not occur if the tracks had mismatched tempos.
  • Editing system 18 audibly alters an acoustic attribute of an audio clip and or track to generate an edited track.
  • the editing system may change the way a clip or track sounds. Such changes may be made in realtime during playback. In some embodiments, the changes may be made in virtual time, before playback.
  • the changes may be effectuated by activating one or more user operable controls, including buttons, switches, dials, faders, and/or elements of a digital interface presented on a display.
  • Digital audio data may be edited by digital filters, or algorithms, which are programmed to alter digital audio data to produce a desired effect.
  • filters may be executed by a processor, application specific integrated circuit, or similar device, of the editing system. In the case of a programmable processor, new filters may be added to a device to facilitate new types of editing.
  • the filters may be added as software and/or firmware updates.
  • the editing system may be configured to receive editing modules, which may be selectively coupled to the editing system to provide new editing functionality.
  • Edited tracks may be stored in memory 16, and subsequently played via the output system or shared by transferring the digital audio file embodying the edited audio content. Like mixed tracks, edited tracks may be stored as self contained files, which include all of the information necessary for playback. Edited tracks, as well as mixed tracks, may alternatively be saved as a set of instructions for altering another data file, such as the file of a constituent clip. In some embodiments, the produced track may not be saved.
  • Digital audio content may be edited to produce a variety of effects. Exemplary alterations include changing tempo and changing pitch. Some alterations may add or subtract selected portions of audio content. For example, sounds may be added to replicate a drum, bass, or other instrument.
  • Selected portions of a clip or track may be extracted.
  • a portion extracted from one clip may be combined with a portion of another clip by the mixing system.
  • Other exemplary editing effects include vocoding, in which audio content is layered with synthetic electronic sounds, for example making a human voice sound robotic or like a talking electric guitar.
  • a scratch effect may be used to alter the sound of a track to mimic a scratch sound achieved when a pickup, or needle, scratches across a phonograph record.
  • a reverb, or echo, effect may be used to cause a selected range of sounds to echo.
  • Output system 20 generates audio-playback signals based on recorded audio clips and produced audio tracks, including mixed tracks, edited tracks, and edited mixed-tracks, which are tracks that have been both edited and mixed.
  • the audio-playback signal may take the form of an electromagnetic signal that may be delivered via wired or wireless delivery mechanisms.
  • the output system may include a digital-to-analog converter for converting digital audio data into analog audio-playback signals.
  • the output system may also include a data decompressor configured to expand compressed digital audio data.
  • the output system may include an amplifier for amplifying the signal.
