Acoustic-URL: Multisignal-Domain and Multichannel Fusion for Unsupervised Representation Learning in Acoustic Sensing

The proliferation of multimicrophone IoT devices—such as smartphones, smart speakers, and wearables—has enabled diverse acoustic sensing applications. However, scarcely labeled data and poor cross-task transferability continue to limit traditional supervised methods. To address this, we propose acoustic-URL, an unsuper...
