Challenges for laboratory instruction due to COVID include lab room occupancy being cut in half, the prohibition of lab partner arrangements, and students (or instructors) who, on any given day, might be unable to attend lab in person. To allow students to perform laboratory exercises at home requires accounting for a heterogeneous set of available equipment (typically of low-precision) and a multiplicity of computing platforms. The author's Mac-only software suite “SHAART Acoustic Tools” needed porting to Windows and Linux executables so students could measure reverberation times at home. In this talk, we share some experiments, apps, and cross-platform tricks that enabled students to have a reasonably uniform experience that was also manageable for the instructor.
