You can get the samplerate and file length of your file by sending a read message to soundfiler and not specifying a table to write to. From that you can calculate the expected play time.

Hey all,
I want to play a wav-file with [readsf~] and I want to loop the wav-file.
This can easily be done by connecting [readsf~]'s right outlet it its inlet.
The problem is that I have a metronome in my patch which is the master of the tempo.
The [readsf~] object will get out of sync with the metronome when it loops the same file over a longer period of time.
That's why I want to constantly check the position of the wav-file that [readsf~] is currently at, when it plays the wav-file.
By this, I can restart/loop the wav-file in sync with the metronome, as soon as it has almost reached its end.
Do you have an idea how I could do that?
 
In a former version of my patch, I did this successfully when I was using [tabread4~] as my file-playing-object, but I needed to switch to [readsf~] in order to implement dynamic loading of wav-files.
 
 
Thanks, Jakob
