Set size of a buffer without erase it
Dear all, I'm writing a patch that use record~ object to record many times into a buffer~.
How can I set the correct size of the buffer?
If I send "size" message to buffer~, it also erases it (see patch below).
Now I'm solving writing to hardisk using static "write temp.aiff" , "size LENGTH" and "read temp.aiff 0 LENGTH" messages.
Of course it's not cheapest solution.
And peek~ / poke~ objects work even slower...
Thank you,
Bruno
If you have Jitter 1.5, you can use jit.buffer~ for this. See patch below.

Thank you very much. Yes, I have Jitter 1.5.
I'm trying to use your patch but when I send a message to trigger I receive the following error:
"• error: jit.buffer~: input matrix too wide"
and buffer is still resetted.
Sorry for my idiocy :-)

There is a crop message to waveform~ which does this...

the crop message can only make it smaller though, right?
is there a way to also make the buffer longer?
(without using jitter)
sorry to hijack bruno's thread but this is something i've also thought about in the past..

copy the content into a bigger buffer~. I think the crop message does
that under the hood.
In the end it depends what you want to do, you can easily just use a big
enough buffer~ and play the part you want. Or create new buffers and
play across multiple buffers... Both would be more efficient than
copying or cropping.

here's a try to record (& play) live recording.
i don't know before the length of this recording.
i don't want to initalize a huge buffer.
for that matter initialize a huge buffer does it take ram of its size ?
is there a better way to do it ?

Buffers store 32 bits values, so a [buffer~] will take twice the space
in RAM as the size of a soundfile with a 16bits resolution.
Don't forget to delete your tmp soundfile when you quit Max.

I recently posted on the javascript-dev list a small java source to do
that. Look for filesys in the forum. Beware, these are the only lines
of java I coded so far, I'm open to any comment.

I didn't test your patch, but recording to a soundfile and then loading
it into a buffer seems a good solution as long you don't need to play
while recording. I'd use the replace message to buffer~ though, which
automatically resizes...
