Systems and techniques for audio synchronization across devices

A system for synchronizing a sound piece across a plurality of devices generating respective audio signals of the sound piece, the system comprising:

• at least one computer processor;
• and
• at least one non-transitory computer readable medium storing processor-executable instructions, that when executed by the at least one processor, cause the at least one processor to perform:
• transmitting, to the plurality of devices, synchronization data indicating:
• an audio sequence of the sound piece for rendering, by the plurality of devices, the respective audio signals;
• and
• a target point in the audio sequence for the plurality of devices to use in synchronizing rendering of the respective audio signals;
• receiving, from a first device of the plurality of devices, a first input indicating a modification to the audio sequence of the sound piece;
• in response to receiving the first input, updating the synchronization data to generate updated synchronization data, the updated synchronization data indicating an updated target point in the audio sequence and the modification to the audio sequence;
• transmitting, to one or more of the plurality of devices, the updated synchronization data, wherein transmitting the updated synchronization data causes each of the one or more devices to render a respective audio signal using the updated synchronization data at least in part by synchronizing the rendering of the respective audio signal based on the updated target point in the audio sequence.

A non-transitory computer-readable medium storing processor-executable instructions, that when executed by at least one computer processor, causes the at least one computer processor to perform a method for synchronizing a sound piece across a plurality of devices generating respective audio signals of the sound piece, the method comprising:

• transmitting, to a plurality of devices, synchronization data indicating:
• an audio sequence of a sound piece for rendering, by the plurality of devices, respective audio signals;
• and
• a target point in the audio sequence for the plurality of devices to use in synchronizing rendering of the respective audio signals;
• receiving, from a first device of the plurality of devices, a first input indicating a modification to the audio sequence of the sound piece;
• in response to receiving the first input, updating the synchronization data to generate updated synchronization data, the updated synchronization data indicating an updated target point in the audio sequence and the modification to the audio sequence;
• transmitting, to one or more of the plurality of devices separate from the first device, the updated synchronization data, wherein transmitting the updated synchronization data causes each of the one or more devices to render a respective audio signal using the updated synchronization data at least in part by synchronizing the rendering of the respective audio signal based on the updated target point in the audio sequence.
