I think it's an historical thing, most audio inlets which might benefit from a signal level message have the [sig~] built in. I understand this might not always have been the case so some more old school PDers use it, and they remain in the help files. I don't know if there's some minor technical benefit to using the [sig~] object, but I've still to find a need for it

Hello, Taking acoustics~-help.pd as an example: is there any reason for the [sig~] object here? Doesn't the float from the gatom automatically get promoted to a signal?
Thanks, Jonathan
