Field notes
The library is arranged around four workflows, from effects and file preparation to analysis and stem separation. Several tools specify their inputs and outputs: the voice recorder uses a microphone, the tap-tempo tool needs no file, and the vocal remover lists vocal and instrumental outputs. The page gives a 250 MB maximum for local files, while noting that actual limits can be lower depending on browser support, memory, and the model.
