Hi all!
At first: thank you Kai and Junichi for your tips concernig the mixer
settings, now I finally managed to do multitrack-recording without the
monitortrack mixing into the new one...
But now the other stuff:
As promised, (or threatened ... :) I made some more trials with ecasignalview,
and I still cannot figure out, what's going on .. Here are I the results
(/dev/dsp1 or alsa,emu10k1 is the used sound device)
1) $> ecasignalview alsa,emu10k1 test.raw
gives
Using audio format -f:s16_le,2,44100
Setting up 2 separate channels for analysis.
(eca-control) ERROR: Connecting chainsetup failed: "Enabling chainsetup:
AUDIOIO-ALSA: Unable to open ALSA--device for capture; error: Device or
resource busy"
--- Unable to start processing. Exiting...However, $> ecasound -i:alsa,emu10k1 ...etc... works just fine
2) $> ecasignalview -i:alsa,emu10k1 -o:test.raw
starts up, but the signal isn't recognized
3) $> ecasignalview /dev/dsp1 test.raw
starts up and the signal is recognized, but volume values for left and right add up continously (cumulative mode?, although no -c specified)
4) $> ecasignalview -i:/dev/dsp1 -o:test.raw
starts up, but the signal isn't recognized
Version: ecasound 2.2.1, on Suse Linux 8.1, Kernel 2.4.19 alsa-version: 090rc3
I believe that it is mainly an alsa-problem, has anyone made similar observations? I remember Hans-Georg Fischer mail (last Saturday) when he reported problems with alsa-drivers which don't appear when using OSS.
Probably the reason is the opening of the 2 separate channels for analysis ??? At least I remember getting device opening failure messages when specifying 4-channel files when working with ecasound, too, so maybe the alsa driver for my card doesn't accept anything with more than 2 channels...
The other thing however is, that ecasignalview always runs in cumulative mode, although no -c option was given.
It's a bit difficult to grasp what's going on as I don't really know how ecasignalview behaves normally, when all's well. (E.g I once read something about ascii-bar graphics, but I don't see any either...) so long Carsten
