Sound playback in R Shiny - suggested resources/packages?

Hi everyone,
I am looking to integrate some sound playback into a shiny app I'm making. Before I get going, I wondered if people have some suggestions as to vignettes or other resources for playing sound files in R and R Shiny, and what are the key packages most people use (e.g., tuneR appears to be popular).
Any suggestions would be much appreciated!
Jamie
