EarAcE

In recent years, particular attention has been devoted to earable acoustic sensing due its numerous applications. However, the lack of a common platform for accessing raw audio samples forced researchers/developers pay great efforts trifles prototyping often irrelevant core functions. Meanwhile, growing popularity active noise cancellation (ANC) endowed earphones with high standard capability yet be explored by sensing. To this end, we propose EarACE first exploiting native acoustics commercial ANC earphones, significantly improving upon self-crafted earphone devices. takes compact design handle hardware heterogeneity and deliver flexible control on facilities. Leveraging systematic study in-ear signals, gains abilities combat performance sensitivity device wearing states eliminate body motion interference. We further implement three major applications showcase efficacy adaptability EarACE; results evidently demonstrate EarACE's promising future in facilitating research.
