Thank you,
I'm not sure it's possible to perform audio modulo with internals
only, here is a workaround with expr~

Hello,
this is quite interesting but there is something I don't get in
attached patch, both 1 and -1 outputs the same thing, so I don't know
if
I've misinterpreted something or if there is a mistake in message
computing
No, you're right. The message based reference is already wrapping over.
I added a [clip -32768 32767] to avoid that.
See attachment.

Hi all
In order to store audio data more efficiently in netpd presets and
also
to transmit live audio through OSC, I'm thinking of ways to convert
an
signal to a 16-bit stream represented as two signals, one for each
byte, the first for MSB and the second for LSB. I already came up
with
a few solutions, but I'm not totally happy with any of them because
they are not very efficient or/and have strange edge cases. It
turns
out what seems a simple task is a bit more complex and probably has
quiet a few totally different solutions.
I would be interested to see with what solutions people come up
with.
Consider it a puzzle, a brain teaser (in case you're done writing
your
paper for pdcon and need some distraction).
Requirements:
* It must be done in signal domain (I was doing it in message
domain
yet, but performance is obviously bad)
* Only vanilla objects are allowed.
* Input is in the range -1 to 1. Input outside this range should
be
clipped and not wrapped around.
* Output is two signals, each consisting of an integer value
between
0 and 255
* The two bytes represent a 16-bit _signed_ integer
You can compare your output with the message version in attached
patch.
If this generates interest and makes some people participate, I'll
disclose my solutions after people submitted their solutions.
