Hi,
I need something that loads 16 wavs (1-channel) and connect them in pairs and outputs a 2-channel audio. I want to choose (switch) which pair is going to output.
Is there a pd for the switching part? If not how I can do that?

How to load wavs into array, because I found how to loop sound with open and bang but I think it is not necessary to open file again.

Hi and welcome to this forum,

You can do this with an object named [multiplex~] (when not dealing with signals, you can use [multiplex]. And the opposite object (one inlet -> several outlets) is called [demultiplex] (and [demultiplex~])). Here is how it works:

As for looping a sound, if you are using [readsf~] then you must open the file again in order to play it. Look what I did in the image above, where I added ", 1" in the end of the open message, so that clicking or banging there will automatically starts playback.

Alternatively, you could load your samples in separate arrays.

Hope this helps, take care,
Gilberto

This really helps, but i need arrays. There is a problem [tabread~] seems to not work with [multiplex~].

Sound files are loaded I've checked that. Does [tabread~] read all array? I've tried to connect it to [tabplay~], but nothing happened.

First multiplexer is left channel, second is right channel I will need to put both channels in new array to get 2-channel wav and send it to [tabplay~] and pass to [earplug~]. So there is 2nd question how to connect two single channel sources into one double channel output.

Hi,

Both [tabread] and [tabplay~] could be used here, but using [tabplay~] is probably the easiest solution. [multiplex~] does work with them, the problem is with your patch above, as that is not the way to use tabread~]. My suggestion is for you to create something like this:

Also, here is a hint: when you come across a new object that you don't know how to use, you can always right click on it and select "help". Normally you will have a working example showing how to make use of it.

As for [earplug~], it takes a mono sound and then creates a binaural version of it using the angles you input. So why don't you use two [earplug~] objects, one for the left channel and one for the right? I don't see why you would need to create two new arrays for 2-channels to play it back.

Hope this helps,
Gilberto

I have had loading already in a patch, forgot to bang tabplay.
This is what I get so far

but can I do this without looping (e.g after clicking switch_pair stop all sounds and start only 2 of them)? What flaws has looping approach? Could it make some lags or increase cpu usage?

With [earplug~] it was my mistake, I understand that now.

@tobix10 Would this work for you?

EDIT: I forgot to add in the picture the bottom [hradio] select which file to read.

You can create any pair you want using the two [hradio] at the bottom.
Here's the patch if you want to try it out: test-multiwav.pd

Thanks a lot, this is a great example. It's give me idea about a few things I was wondering how to do.

Really thanks to @gsagostinho and @rjp9, now I think I'll be able to complete my patch.
