I wan to combine 3 mono audio files in one 3 chanels audio file.

I am using the following command:

ecasound \
    -a:1 -f:16,1,44100 -erm:1 -i file1.wav \
    -a:2 -f:16,1,44100 -erm:2 -i file2.wav \
    -a:3 -f:16,1,44100 -erm:3 -i file3.wav \
    -a:1,2,3 -f:16,3,44100 -o trio.wav

I tried also:

ecasound \
    -a:1 -f:16,1,44100 -erc:1,1 -i file1.wav \
    -a:2 -f:16,1,44100 -erc:1,3 -i file2.wav \
    -a:3 -f:16,1,44100 -erc:1,2 -i file3.wav \
    -a:1,2,3 -f:16,3,44100 -o trio.wav

The 3 input files are mono 44100hz PCM 16 bits.
I want in output a 3 channels 44100hz PCM 16 bits.

ecasound generate the output file (3 channels) BUT:
the first chanel is a mixing of the 3 input files
the second chanel is garbage
the third chanel is correctly the file3 chanel

Am I missing something?
any help is welcome.
