i don't think that there is a problem here.
the checks mainly check whether something special is needed to support
large files, or whether it works out of the box.

So you're saying that despite 'no' below, we can expect this build to 
read/write large files?

Following features were selected:
Debugging info:         no      
Effects enabled:        yes     
Largefile support:      no      <-----
Termcap:                ncurses

Ok, good to know, and a warm welcome to the new maintainers! And I must 
say a _big_, _big_ thank you to Junichi (cc'ed) for maintaining ecasound 
in debian for so many years (Junichi was active on this list already in 
1999, so he's been helping out since the beginning).

Then about configure script stuff:

Is this on a 64bit system perhaps? I believe on 64bit systems, 
_FILE_OFFSET_BITS has not effect, and then the above checks should be 
correct.

So if this is indeed the case, then the things are working as they should, 
but ecasound's configure summary is just misleading (it should say 
"largefile for 32bit systems...: yes/no".

I'm afraid you've hit this old issue:
http://www.eca.cx/ecasound-list/2008/07/0048.html

There is some progress since then (there's now a proper end-of-stream
marker implemented), but the draining is still not implemented.

The (very) crude fix is to just lower the buffersize (-b) to make sure the 
end is played out as well. -z:nointbuf will help as well (further reduces 
device buffering).

But thanks for reminding, this is a stupid bug and should be fixed.

PS This doesn't impact JACK usage, only ALSA (but still an ecasound
    problem, so ALSA is not to blame)...

It is a 64-bit system.

Good to know. AFAIK, the package is ready-to-go, once the
higher-ups give their okay. 

It will appear in "unstable", which many people use, and
from which Ubuntu draws a lot of their packages.

Squeeze, the new Debian stable, will be released soon,
with an older (but still modern) ecasound, 2.7.0.

24/7 recording split into files

Hi,

I want to record the audio line in 24/7 and split it into one hour
files. This question has popped up bevore on this list, but I only
found a statement that this feature is planned for ecasound.

Is  it already implemented? If no, are there any other suggestions on
how to implement this?

At the moment I'm starting a cron job every hour (2 minutes earlier
and wait in a loop to start). It works ok, but I miss arround 1/10 of
a second on the splits.

Regards,
Peter

Hi Peter,

I recently came across rotter, which is an audio logger that might do what you want, but I've never tested it.
