Abstract: Methods, systems, and devices for data processing at a software development kit running in a mobile device are described. A software development kit may receive, from a mobile application running on the mobile device, a logged event indication in response to an event occurring within the mobile application. The software development kit download, from an application server and before receiving the logged event indication, a data payload including a set of triggers, a set of rules associated with the set of triggers, and a set of processing commands associated with the set of rules. The software development kit may then identify the received logged event indication as a trigger from the set of triggers, evaluate a rule associated with the trigger based on the identifying, and process a processing command associated with the rule, where the processing command includes utilizing native code of the mobile application.

Abstract: A portable reverberation device for attaching to a musical instrument with a distal end that can be adjusted to alter a distance between the ends of the portable reverberation device. The device includes a cup attached to a collar to receive incoming sound waves and a spring stretched inside the body. The device further includes an attachment mechanism with a clamp adapted to attach the portable reverberation device to the musical instrument.
