Hi all, i know this is probably an annoying question but Im trying to record a minute long sample of my patch using writesf. I think Ive got the patch hooked up correctly and it drops the wav file in my folder only there is nothing on the wav file. Its always 4kb and does not play anything.

Ive looked in this forum and gogled the problem for the last few hours to no avail. Any help would be greatly appreciated!

cheers

hi percy,

this happened to me a lot of times. If you want to avoid it, make sure you feed writesf~ with all the messages it need in the right sequence :
[Open blablabla.wav(

THEN

[Start(

AND

[Stop(

Also, make sure Pd is computing audio when you start recording.
This sounds very silly, but one tends to forget even the simplest things after having worked on a patch for hours.

anyway, everytime something weird happens in Pd, take a look at the log in the main Pd windows. It will tell you more often than not what went wrong.
I hope this helps.

thanks for replying.
Okay in the error log box it says
error: writesf: start requested with no prior 'open'

Not sure whats this means, Ive tried doing the boxes in the right order.
I have included the recording patch. Is it correctly done?
There are 2, the one with the orange box was an example I downloaded, and the smaller one was my own. hope thats helpful

Oh i tried putting them in the order you said rather than them all coming of the left inlet to writesf. wasnt sure if thats what was meant. - anyway, was the same error.

I'm not sure what you're trying to do with the open message? The simplest form is to use [open xxx( where xxx indicates the path/filename of your file. This can be a relative path/filename or an absolute one, but it for sure does not accept whitespace characters. There are more options for the open message which are explainded in the writesf~ helpfile (right-click). Other than that you indeed need the correct message order like pamelapopo explained.

The entry in the log means that the writesf~ received a start before an open message.

Like Domien wrote, there needs to be something that indicates where to save the file and what name it should have in the [open( message. If you are using Pd in windows, the message should typically read something like that :
[Open C:/Mysong.wav(

This will save your soundfile to the C partition of your hardrive under the name of Mysong, in the wav format.

Incidentally, i hope the patch you're trying to record from looks different from what you have attached, because there is no sound coming to your writesf. You will get a blank wav file no matter what.

If that can help, i have attached a patch that can be used to record a stereo wav file and save anywhere you want. Just call it in any patch by creating an [recordwav] object, and you should get a canvas with 3 buttons on it. first click on Save, then on start and finally on stop, and that should do the job.
