Hi,

hello. Im fairly new to pd, and am trying to write a patch that when a
volume threshold is broken (from the built in laptop mics), it i will
record audio for duration x, and save it as a file, however if the
threshold is broken again during duration x, duration x is reset and
only saves out the file until the threshold isnt broken for duration
x. when the file is done recording, and the threshold is broken again,
I would like it to start recording another file. the reason I'm making
this is because ive been made aware that i've been saying strange
things in my sleep (that i dont remember), and I wanted to try and
record them. Eventually with the onboard webcam too, but just audio
for now.
I'm not sure I'd want to know if *I* I say strange things during sleep :)
I'm sure there are simpler ways to do what im doing, and I'm open to
suggestions (or if there are other patches out there like this).
The three problems Im having at the moment are:
1) I had "del" or "delay" working for awhile, but then it mysteriously
stopped working. even when i delete it and repatch it. if you click
"resets counter" there's a bang both before and after the "del 5000"
on the lower right. i have no idea why or how to fix it.
There should be a [sel 1] between the [<= 1] and the [delay] otherwise
the [delay] gets a 0 or a 1
2) I'm having a hard time figuring out how to keep the file recording
when the threshold is broken during duration x. The problem is that
the way I have it set up, is that if the threshold is broken again, it
will initialize a new file to be written, which I
You have to set it up so that once the threshold is broken you ignore
further breaks, unless the signal goes back down. Look at [spigot] for
example. In this case though you may also want to add a 'hold' time
before resetting this when the threshold goes down especially if the
signal can be very uneven or with abrupt bursts.
Have a look at this trigger I made (it does something different but the
basic principle is the same: do something if a volume threshold is
broken): http://lorenzosu.altervista.org/pd/trigger/
can't figure out how to bypass. Perhaps "load banging" an open message
for the initial file to be written, and then the subsequent ones can
be initialized after the previous has finished writing? However I
think it would be better is:
3) So far I've only devised a very wonky way of recording the next
file. If you click on "pd recordingsel" in the upper left, you can see
how I've set it up with switches and a limited amount of files ready
to be made. I know there must be a better way to do this, so that it
will just continuously record new files with virtually no limit.
Yes: look at [makefilename] and attach a counter to it something like
[f 0]X[+ 1]
|
[makefilename sleeprecord%02d.wav]
This will generate sybols sleeprecord00.wav, sleeprecord01.wav etc. at
each bang at the [f]
Good luck,
Lorenzo.
Thanks for helping a newbie!
