A system includes a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to receive an audio input representing a percussion performed by a user and classify, at a trained neural network, the audio input as a particular musical type.

Systems and methods for calculating mobility metrics associated to a plurality of wearable sensors in various arrangements comprising a plurality of communicatively-connected sensors comprising inertial measurement units (IMU) attached to connected bodies of a hinge or ball joint in communication with a computing device. Systems and methods for quaternion calculations comprising a first sensor's quaternion output as estimate into another sensor's quaternion calculation to improve the other sensor's quaternion estimate and vice versa. Systems and methods for data synchronization of a plurality of sensors involving building an external reference time vector and interpolating the sensor's data based on the reference time vector. Systems and methods for calculating a sensor's orientation and position based on the inertial measurements captured by the wearable sensors during hinge or ball joint movements to, at least, calculate a joint angle.

A method includes receiving, at a mobile device, survey data comprising real-time survey user input associated with watching a video program and survey audio from the video program, the survey audio being recorded via a microphone of the user mobile device during the real-time survey, transmitting, to a network server, the survey data as part of a data package, wherein the network server receives an audio file associated with the video program, compares the audio file with the survey audio to yield a comparison and aligns, based on the comparison, the survey audio with the audio file to yield a modified data package and receiving a confirmation of a creation of the modified data package.

A resonator absorber with adjustable acoustic characteristics made in the form of a cuboid with sidewalls and with an open upper face that is covered by two identical movable perforated plates to allow partial overlapping of the the plates. Each plate is equipped with bores forming a planar binary amplitude diffusor by using a maximum length pseudorandom binary sequence mapped to 2D space to determine the bore position. Bores are arranged in rows which do not overlap between plates. The resonator absorber has six cavities of different geometry situated below the perforated plates, where five cavities simultaneously change the volume with movement of the perforated plates. The resonator absorber is useful for tuning the acoustic characteristics of the environment.
