Yes, but I haven't seen it like that, if it works though...

Don't put the slashes around your sample rate. I'd normally put
all the sl3 code inside your complex_converter, where you said:
<br>
slave sl3
<br>
I would have written:
<br>
slave {
<br>
pcm "hw:1,0,0"
<br>
...
<br>
}

So made ~/.asoundrc<br>
<blockquote>pcm_slave.sl3 {
<br>
pcm "hw:1,0"
<br>
channels 2
<br>
rate 44100<br>
}
<br>
<br>
pcm.complex_convert {
<br>
type plug
<br>
format S16_LE
<br>
slave sl3
<br>
}
<br>
</blockquote>
but got<br>
<blockquote>pi@cuberadio:~ $ arecord -t wav -r 44100 -c 2 -f S16_LE

| Not sure exactly what S16_LE. Cant find a list of the formats. Or
is this the format of the card, not the format I want.

<blockquote cite="mid:1604010903140.8325@freeshell.de" type="cite">S16_LE
= signed 16bit Little Endian, which is what you want. Take a look
at the manpage for arecord:
<br>
man arecord
<br>
then search for s16_le:
<br>
/s16_le
<br>
you will come to a full list of accepted bit depth/sample formats
of ALSA.

Not against using jack but only if I have to. It seems more
complex and I am very new to al this.

If you have to work with the asoundrc, JACK will be easier on
every modern system, that I know off. It will take care of
different bit depth automatically. Maybe give it a try at some
point. If you like graphical user interfaces qjackctl is a good
companion to look at connections and/or make them yourself.

Its headless but I could ssh -X I guess. Ime just trying to get it
to work/take the path or least resistance. Don't mind taking a
couple of hours working this out but I do find the documentation for
Linux stuff makes my head spin, and I worked in It for over 15
years. Ime basically now a creative, I do video production
mainly. figured if I could do it without installing extra framework
that would be good. I help at a local volunteer run
venue/performance space, <a class="moz-txt-link-freetext" href="http://cubecinema.com/">http://cubecinema.com/</a> (Server offline
currently as it is hosted onside and power is down due to electrics
needing total overall). This is what i am trying to sort out this
stuff for and trying to find time to do it. OK, ime a bit lazy, my
boss when I did IT said this was a good thing, it means you try to
find the easiest way of doing stuff;). I wish I had a day or too to
work fully through docs but its difficult to find the time.<br>
