Abstract
A system and method eliminates the drag associated with CPU drag on experienced by combine audio streams from multiple sources. The embodiments receive audio signals from two separate audio sources and apply a MIDI based timing signature to the audio signals. The audio signals are synchronized according to the MTC signature signal and combined, when synchronized, at a summing module for output as a combined audio stream.
Claims10
An audio processing system for providing collaborative input of music streams, comprising:
- a housing including:
- a first USB audio input hub for receiving a first audio signal from a first digital audio workstation,
- a second USB audio input hub for receiving a second audio signal from a second digital audio workstation,
- a musical instrument digital interface (MIDI) timing engine coupled to the first USB audio input hub and to the second USB audio input hub, the MIDI timing engine generating a MIDI time code (MTC) timing signature signal provided to the first USB audio input hub and to the second USB audio input hub;
- a controller coupled to the MIDI timing engine, configured to synchronize transmission of the first audio signal from the first digital audio workstation through the first USB audio input hub with the second audio signal from the second digital audio workstation through the second USB audio input hub using the MTC timing signature signal;
- and
- a summing module coupled to the first USB audio input hub and to the second USB audio input hub, the summing module configured to:
- sum the synchronized output of the first audio signal from the first digital audio workstation from the first USB audio input hub with the second audio signal from the second digital audio workstation from the second USB audio input hub, and
- output the synchronized and summed first audio signal and second audio signal as a combined audio signal.

A method of providing collaborative input of music streams, comprising:
- receiving at a first USB audio input interface, a first audio signal from a first digital audio workstation,
- receiving at a second USB audio input interface, a second audio signal from a second digital audio workstation,
- receiving a user input at a controller to synchronize the first audio signal with the second audio signal;
- generating, in response to the received user input at the controller, a musical instrument digital interface (MIDI) time code (MTC) timing signature signal;
- broadcasting the MTC timing signature signal simultaneously to the first USB audio input interface and to the second USB audio input interface;
- combining the first audio signal with the second audio signal in synchronization according to the MTC timing signature signal;
- and
- outputting the combined and synchronized first audio signal and second audio signal as a combined audio stream.
