I’m trying to perform an amateur experiment related with sound waves. Let’s say I have a file on my iCloud Drive, let’s call it
wave1.wav. I want to play it on my Mac/iPhone, but with a slider or another way of controlling the playback delay at the level of single milliseconds.
Does such app exist? It can be a feature of some commercial music mixing software, as long as it’s cheap (< 20 USD) or has a free trial.
