Abstract: A data package is received from a plurality of devices. Each data package comprises audio content captured by a respective device from the plurality of devices. Each data package further comprises metadata including a location of the respective device when the audio content was captured and a time at which the audio content was captured. A subset of the data packages that include audio content captured within a specified geographic area and within a specified time period is identified based on the metadata. A playlist for the specified area and the specified time period is generated based on the subset of data packages. The playlist may be provided to at least a first device.

Abstract: A messaging server system receives audio data packages from a plurality of client devices. Each audio data package includes audio content captured by a respective client device from the plurality of client devices, and location data describing a location of the respective client device when the audio content was captured. The messaging server system identifies, based on the location data included in the audio data packages, a subset of the audio data packages that include audio content captured within a predetermined geographic area. The messaging server system generates, based on the subset of the audio data packages, a playlist of audio content items for the predetermined geographic area, and provides the playlist of audio content items to at least a first client device.

Abstract: Systems and methods provide for capturing a plurality of segments of an audio stream and, for each segment of the plurality of segments of the audio stream: performing feature extraction on an audio signal of the segment using a feature extraction machine learning model that analyzes the audio signal to generate a feature vector for the segment and generating a prediction value for the segment for whether there is music in the segment using the extracted feature vector and a music detector machine learning model. The systems and methods further provide for generating a probability value that there is music in the audio stream based on the prediction value for each of the plurality of segments and causing the audio stream to be identified based on determining that the probability value that there is music in the audio stream meets a predetermined threshold.
