Applause length is recorded from the very first clap, cheer, or laugh to the resonance from the final clap ending. Applause only at the end of the composition and not in between movements or during the piece is recorded. "Booing" subtracts from any applause time, unless the booing is not directed towards the nature of the piece, performance, or the performer(s) themsel(ves) (for example, booing the antagonist of an opera in good humour).
