Embodiment Construction

[0026] In this specification, the term "rendering" or "rendering" shall refer to the work of making an audio data set, music track or audio channel, etc., audible to a user.

[0027] An audio track (eg, a song) typically includes one or more audio components. Each audio component corresponds to a different part of the audio track, such as a different instrument, vocals, etc. image 3 An illustration of an adaptive media file used to generate an audio track can be seen in , showing an adaptive media file with 10 audio components represented by vertically extending bar elements. The audio components may each correspond to a corresponding audio channel, or an audio component composed of more than one audio data set may be spread over more than one audio channel. For example, image 3 , the "Piano High" audio component corresponds to a single audio channel, and the "Piano Low" audio component corresponds to two audio channels. The playback tempo of the track is indicated on the...

Abstract

A method for constructing an adaptive media file comprising a plurality of audio components configured to form an audio output arranged to have a controllable tempo, the method comprising: providing a The first audio data associated with the first audio component in the components, set the playback tempo range of the first audio data, provide the second audio data associated with the first audio component, set the second audio data The playback tempo range of the second audio data is different from the tempo range of the first audio data, and the first audio data, the second audio data and the corresponding playback tempo range are associated.

Description

technical field [0001] The present disclosure relates to methods for constructing media files and associated files. More specifically, but not exclusively, audio file types are proposed that allow playback of audio at different tempos. Methods for controlling the playback tempo presented by a music track are also discussed. Many other applications will be apparent based on the discussion below. Background technique [0002] In the music industry, many standard and successful music tracks are often remixed (ie, remade) to create different songs. Even if the melody is largely preserved, remixing often alters the song's original tempo (rythem) or beats per minute (BPM) to create a different mood or atmosphere. A song can be sped up to give it a club feel, and slowed down to give it a more casual input. [0003] A song or music track is usually the result of a mix of several audio data sets (e.g. 8 audio data sets), each corresponding to a specific function (vocal 1, vocal 2...
