Hallo,
what formula might one be using to determine periodicity as rate in ms ?
For example, say you know total frames of a video file and you know this file is 24 fps. You can say that it vibrates at 24 Hz so what is the periodicity of the wave in ms ?
the appended patch implements an incomplete version the idea using [pix_film] ideally settings would be initialized using a [loadbang].
