Abstract
A file creation process, file format and playback device are provided that enables an interactive and if desired collaborative music playback experience for the user(s) by combining or retrofitting an “original song” with a MIDI time grid, the MIDI score of the song and other data in a synchronized fashion. The invention enables a music interaction platform that requires a small amount of time to learn and very little skill, knowledge or talent to use and is designed to bring “mixing music” to the average person.
Claims15
A method of creating an audio file including:
- receiving waveform data representing a musical rendition;
- analysing the waveform data to determine transient positions in the waveform;
- using the transient positions to determine bar markers representing bar start/end positions for the rendition;
- synchronizing a MIDI time grid with the bar markers;
- determining MIDI data including a musical score for the entire rendition;
- synchronizing the MIDI data with the MIDI time grid;
- and,
- creating a file including the MIDI data in synchronization with the MIDI time grid, bar markers and waveform data.

A method of creating a timing file for audio processes including:
- receiving waveform data representing a musical rendition;
- analysing the waveform data to determine transient positions in the waveform;
- using the transient positions to determine bar markers representing bar start/end positions for the rendition;
- determining MIDI data including a musical score for the entire rendition;
- synchronizing the MIDI data with the MIDI time grid;
- and,
- creating a file including the MIDI data in synchronization with the MIDI time grid, bar markers in a timing file separate from the waveform data.
