Each package ships libaudiocpp, which upstream's own third-party notices describe as Apache-2.0 with BSD-3-Clause PocketFFT-derived code retained in it, and installs those texts under /usr/share/licenses. A license array of MIT alone describes only the project's own source, so pacman -Qi misreports what the package contains.
