You need to wrap f_small.wav in a .ewf file. read about ewf here:

Re: new eca.cx webserver/DNS, mailing list change on the way

Hi,

today I've changed the eca.cx MX records (i.e. a new mail server is
handling all mails for eca.cx), and unfortunately not all went smootly.  
First, it seems that some mails from sf.net are not coming through to my
accounts at eca.cx.

More importantly, the ecasound-list <at> eca.cx alias does not work.
Sf.net does not accept mails, forwarded from the new eca.cx mail server. 
This means that the address:

   ecasound-list <at> lists.sourceforge.net 

... must be used from now on for posting to the list. Mails to the old
ecasound-list <at> eca.cx and ecasound-list <at> wakkanet.fi addresses will end up 
to my personal mail box. I'll try to bounce these to the list manually.

... otherwise the eca.cx hosting changes are now almost all done.  
Hopefully we can soon return back to the normal development routine and
forget about these project infra worries.

Re: ecasound and ladspa

Hello,

Yes, you need to feed the splitter a stereo audio stream, with valid 
data on the first channel. The resulting stereo output stream will
contain splitter's outputs 1&2. So something like:

ecasound -f:16,1,44100 -i mono.wav -erc:1,2 -el:com_splitter -f:16,2,44100 -o stereo.wav

Ecasound tries to map ports of multi-channel LADSPA plugins to 
matching channels of an Ecasound chain. If this fails (the chain
doesn't have sufficient in and out channels), Ecasound instantiates 
multiple plugins and uses them in mono/1ch mode.

Unfortunately this is not possible.

Many thanks Aaron for performing these tests! Does anyone have test cases
that still cause problems (with the 20041221 snapshot)? If not, we are one
step closer to releasing 2.4.0.

trouble with the mailing list

Hello,

unfortunately there are still troubles with this mailing list. It 
seems that at least my mails to list are lost somewhere. Let's see
if this post comes through (I'm temporarily using a different smtp 
server _and_ a different from-address -> sourceforge's SMTP server
makes a dummy SMTP connection to check that the from-address is
valid in addition to the normal checks concerning the connecting SMTP
server; only after these checks it accepts to receive mail).

I've submitted a new support request to sourceforge.net and the issue is
now under study:

https://sourceforge.net/tracker/index.php?func=detail&aid=1118006&group_id=1&atid=200001

Oops, thanks for the note. This too has been fixed in 2.3.4. :)

Re: Resampling in realtime

Hello,

On Mon, 24 Jan 2005, Simon Werner wrote:

no, you cannot "slave" a real-time object to resample or resample-hq.

> -f:24,1,44100 -o rec1.wav

But you can do the reverse:

ecasound -t:3 -f:24,8,96000 -i alsa,default -erc:5,1
 -f:24,1,96000 -o resample-hq,44100,rec1.wav

... resample-hq is quite cpu-intensive (doesn't run in real-time on my 
dual-450Mhz), so if you have problems, try with plain 'resample'.

> I was also wondering if the following (possible) bug has been fixed:

This has been fixed in the latest snapshot:
http://ecasound.seul.org/download/snapshots/ecasound-2.3.6-cvs-20041222.tar.gz

Please test the resampling functionality for any bugs. I'm hoping
to release 2.4.0 soon.

Oops, I forgot the reply-to header -- that was still pointing to the old
address. I now disabled it altogether. The list behaves now like most
other lists at sf.net (ALSA and JACK lists for example).

PS Always up-to-date info about the list can be found from:
