Methods and devices to generate multiple-channel audio recordings

A mobile device, comprising:

• a processor;
• an audio recording device that records first audio of an event;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to:
• initiate a registration of the mobile device in response to determining that the mobile device is in a physical location of the event;
• send registration information associated with the mobile device to a server to register the mobile device for the event;
• receive first synchronization information from the server in response to the registration information;
• associate the first audio with a first set of timestamps based on the first synchronization information;
• send the first audio to the server, wherein the server combines the first audio with second audio of the event, the second audio recorded via a different device than the mobile device, the second audio sent to the server by the different device, wherein the different device receives second synchronization information from the server, the different device associates the second audio with a second set of timestamps based on the second synchronization information, and wherein the server combining the first audio with the second audio includes synchronizing the first audio with the second audio based on the first set of timestamps associated with the first audio and the second set of timestamps associated with the second audio;
• receive the combined audio from the server after completing the recording, wherein the combined audio comprises a multiple-channel audio recording including the first audio and the second audio being on separate audio channels;
• and
• suppress an audio channel of the first audio or the second audio in the multiple-channel audio recording during playback of the received combined audio, wherein during the playback a different audio channel of the first audio and the second audio that is not suppressed is played.

A method of recoding audio, comprising:

• receiving registrations from a plurality of devices located at a physical event location;
• determining that the registrations correspond to a same event at the event location;
• sending synchronization information to each of the plurality of devices in response to a corresponding registration from each of the plurality of devices;
• receiving a plurality of audio channels from the plurality of devices, each of the plurality of audio channels representing audio recorded at one of the plurality of devices, each of the plurality of audio channels associated with a set of timestamps based on corresponding synchronization information received from the server;
• combining the plurality of audio channels to form a combined audio recording, wherein the combined audio recording comprises a multiple-channel audio recording including the plurality of audio channels with each audio channel being a separate audio channel within the multiple-channel audio recording, and wherein combining the plurality of audio channels is performed after the plurality of devices have completed recording, combining the plurality of audio channels including synchronizing the plurality of audio channels based on the corresponding set of timestamps associated with each of the plurality of audio channels;
• and
• sending the combined audio recording to at least one of the plurality of devices, wherein the at least one of the plurality of devices suppresses at least one of the plurality of audio channels in the multiple-channel audio recording during playback of the combined audio recording, wherein during the playback remaining of the plurality of audio channels that are not suppressed are played.
