confused about what is the best way to do that, the choices being [samphold] and [env]. So I'd also be interested in the best (most accurate) answer.
Andy, [samphold] as well as [snapshot~] do give you the amplitude value of one single sample, which for audio signals is often in the range between -1 and 1. [env~] will give you an dBRMS value (the mean of all absolute amplitudes over a certain time window, converted to dB.
Was that your question?
I'rather be interested in the difference between [samphold~] and [snapshot~]. They seem to almost do the same thing to me.
best, P
