Hello, I am working currently with Pure Data for a project and I made the following patch that loops reproducing a .wav file (that later goes into the puckettshiftter). patch

(if you also want the .wav file you can download it here: measureWalls.wav )

The thing I get is sometimes the loop reproduces normally and sometimes the sound overlaps (like if two samples played at the same time) purely random and I don't know why is it occurring this (maybe the loop logic is wrong).

Also, whenever I try to stop the loop using the stop message into readsf~ object not always stops it at first interaction, requiring several clicks in order to do so.

As an extra specification I'm using a sample rate of 48000 Hz for the patch (not sure if relevant of the error troubling).

Not sure if this is the right place on the forum to ask for help into this, recently started with PD and I know very little about it.

Hope someone can help me with it. Thanks in advance!

@Zurd-IO Hello..! and welcome to the forum. Yes, you are in the right place.
You cannot stop it with a message to [readsf~] because you have already written it to the delay line using [delwrite~] and the rest of your patch is playing that delay line all the time.

Also, when [readsf~] has finished playing (and therefore writing to the delay line) it does it again..... after a delay set by any message to [r frequency].
So while [readsf~] is writing to the delay line (in real time) you are reading the delay line in non real time.
and then telling it to start again will re-start the track in the middle of a [delwrite~] if you do it within the 5000ms .... I cannot completely get my head around it...... but anyway, what you are doing is very wrong.

So the question is, before we try to help...... what are you trying to achieve?

If you want a fixed 5 second loop then you should read the file into the delay line once only, and use a [delread~] to feed the output of the delay line back to the input of [delwrite~]
You can stop the loop by breaking that link...... but you will have to wait 5 seconds for it to play out.
If that is not acceptable then just add a volume control that kills the audio output as you stop the loop.
