Messages

bang

If a file has already been opened, either with the open message or specified by an argument to sfinfo~, bang reports the number of channels, sample size, sample rate, and length in milliseconds out the sfinfo~ object's outlets.

(drag)

Drag supported audio files directly onto sfinfo~ to report info.

getnamed

Arguments

object-name [symbol]
In left inlet: The word getnamed, followed by a symbol which specifies the name of an sfplay~ object, interrogates the named sfplay~ object and reports the number of channels, sample size, sample rate, file length in milliseconds, sample type, and filename out its outlets.

open

Arguments

filename [symbol]
The word open, followed by a name of an audio file, opens the file if it exists in Max's search path. Without a filename, open brings up a standard open file dialog allowing you to choose a file. After the file is opened, sfinfo~ interrogates the file and reports the number of channels, sample size, sample rate, file length in milliseconds, sample type, and filename out its outlets.
