Hi all

I'm quite new to Pd and this forum.

Does anyone have any idea how to pan a sound file played from an array? I am hoping to pan just before the dac~. Would it be different for a mono and stereo?

Thansk in advance.

sorry i forgot to add my question about stereo. I currently have a mono file player patch which loads a sample into an array and uses the phasor~ object to playback through the array (allows me to easily loop!). However how can i convert this whole patch to stereo. in particular the playback using phasor?

Many thanks

Hello BB, welcome.

To pan a mono signal first split it into two. For very simple panning one side is multiplied by x and the other side is multiplied by 1-x. The value x can be a float
message or audio signal in the range 0-1

/ x \ 1-x

Better panning is possible if you make the control values sqrt(x) and 1-sqrt(x)

If your file is stereo and you want both channels you need 2 arrays, one for left side and one for the right side. Check out the help file on [soundfiler] to see how to get both channels. You will use the same [phasor~] to index both arrays.

Panning a stereo signal is more complex, but I think you can work it out once you have panned a mono signal.

thanks obiwannabe!

I got the stereo working with two arrays yesterday, reading both from a phasor. Pretty damn simple really! I'm gonna try the panning.. hopefully it will work... will get back to you.

hello,
I was searching for panning help and found this, I know it is old (and simple!), but I was hoping someone could elaborate on the signal input area.
I have been playing around with a 2 channel output and would like to add a slider that pans left to right....
thanks,

Heres something that might help you.

I've also put notes in it to make it somewhat more understandable.
Someone else could probably write a cleaner, simpler version, but this one works for me.

This is just panning a mono file.
