This one is almost correct. Let's make a few changes:
ecasound \
-a:1 -f:16,1,44100 -i file1.wav \
-a:2 -f:16,1,44100 -erc:1,3 -eac:0,1 -i file2.wav \
-a:3 -f:16,1,44100 -erc:1,2 -eac:0,2 -i file3.wav \
-a:1,2,3 -f:16,3,44100 -o trio.wav
In other words when copying channels 2 and 3, we mute
the source channel (ch1 in both cases) after copying
the data.
-------------------------------
I tried that and it almost works.
1/ In fact, we also need to mute *all* the other channels not only the
souce channel:
ecasound \
-a:1 -i file1.wav \
-a:2 -erc:1,2 -eac:0,1 -eac:0,3 -i file2.wav \
-a:3 -erc:1,3 -eac:0,1 -eac:0,2 -i file3.wav \
-a:1,2,3 -f:16,3,44100 -o trio.wav
2/ The -f:16,1,44100 is not nedeed for the input files.
3/ The last thing is :
The first second of the output wav file is garbage for the third
channel, I don't know why !
