Time-based audio recording and analysis
by Jared 16 Apr '07

16 Apr '07

I'm interested in having a PD function which, when activated, records audio for a set amount of time (probably about 5 seconds), performs an analysis on that recorded audio, and then outputs the result. I'm specifically doing frequency analysis but can't imagine that would matter. Any suggestions on how to allow something to run for a specific amount of time would be appreciated. I've searched the list archives, and will continue to do so, but most of the time-based stuff I'm seeing is how to keep track of time rather than do something for a set length of time. Thanks for your help! -Jared

There's an interim update of serial here, it's much faster: http://www.cycling74.com/twiki/pub/IncrementalDownloads/WebHome/serial06100… Martin

If someone wants to send me specific URIs where they are inconsistent, I will get around to making the change once the grants are finished. One question for the PD community: can anyone give me an estimate of the number of users/developers worldwide? in your country (Austria, Finland etc.)? How many people are on the PD list? thanks very much. yours, Andrew

Array size
by marco liuni 16 Apr '07

16 Apr '07

Hallo, my name's Marco Liuni; I'm trying to read a 4 channels audio file using 4 arrays, but I can't cause the file is too big. I've tried with this | read -resize -maxsize <n> $1 $2-array1 $2-array2 $2-array3 $2- array4 ( [soundfiler] but when I use <n> over about 8000000 it says this error: usage: read [flags] filename tablename... flags: -skip <n> -nframes <n> -resize -maxsize <n> ... -raw <headerbytes> <channels> <bytespersamp> <endian (b, l, or n)>. How can I force array size limit? Thank you very much. Marco

by Greg Pond 15 Apr '07

15 Apr '07

To Pd'ers in Europe: I am going to be working for most of the month of May in western Ireland, working on Pd- based sound installation in some old buildings. I wont be too far from Galway and will be passing through Oslo, Dublin and London. I will be working for a few days at the F+F School of Art in Zurich and screening videos in Basel. If anyone can point me to fellow Pd'ers or noteworthy projects in these places please contact me off-list. I would like to see what is happening out there. thanks, Greg
