I do use a clap slate again with ML RAW-
but I liked it without the slate. I have used pluraleyes for over a year now and it saves a LOT of time.

well, a clap sound would not be unique enough for pluraleyes to sync it.
I was thinking more like the Audio would already be running, and immediately after starting the video ( in our ~5 second WAV )
you ( your assistant, your clapper, anyone ) would say the take title and number - as always-
which would be unique enough for pluraleyes to sync the external audio.

- if you dont know pluraleyes -
it compares the waveform of different sources of the same recorded event to match audio position in your timeline.
