Abstract: Introduced here are approaches to training and then employing computer-implemented models designed to upsample discrete audio signals to higher sampling rates. Assume, for example, that a media production platform obtains a first discrete signal at a relatively low sampling rate. The relatively low sampling frequency may make the first discrete audio signal unsuitable for inclusion in media compilations, so the media production platform may attempt to improve its quality through upsampling. To accomplish this, the media production platform can apply a transform to the first discrete signal to produce a first magnitude spectrogram. Then, the media production platform can apply a computer-implemented model to the first magnitude spectrogram to produce a second magnitude spectrogram. Thereafter, the media production platform can apply an inverse transform to the second magnitude spectrogram to create a second discrete signal that has a higher sampling rate than the first discrete audio signal.

Abstract: A system comprises error microphones disposed in a predetermined pattern to capture audio signals including speech and one or more reference sensors to capture a reference noise signal from a noise source. A portion of the reference noise signal is removed from the captured audio signals to generate partially processed audio signals, which are paired to form signal pairs. For each signal pair, a modified cross-correlation vector, with effects of low frequency contents removed, is generated, then converted to a rotated angular domain cross-correlation vector based in part on a physical angle associated with locations of an associated pair of error microphones. The rotated angular domain cross-correlation vectors are summed, and a weighting vector is applied to the sum to identify direction information of a desired audio signal associated with the speech. The directional information is utilized to beamform the partially processed audio signals and output the desired audio signal.

Abstract: Systems, apparatus, and methods for encoding telemetry data as audio waveforms. Action cameras may be used to capture telemetry data, which in some applications, may be more useful than its audio/visual media capture. For example, a user may desire the “look-and-feel” of one camera but would like to use the telemetry track information from an action camera. In so-called “piggybacking” operation, the user may rigidly affix the two cameras and use the video track with the telemetry track in post-processing. Unfortunately, time-aligning the two tracks can result in relative drift over time. Various embodiments of the present disclosure transfer telemetry data as data-over-audio. The data-over-audio may be sampled according to the recipient device and recorded at capture. Subsequent post-processing may be performed with the time-aligned tracks.
