Re: [Alsa-user] combine usb microphones (joop)

Something like this:
pcm.fourchannels {
type plug
slave.pcm {
type multi
slaves {
a { pcm "hw:0" channels 1 }
b { pcm "hw:1" channels 1 }
c { pcm "hw:2" channels 1 }
d { pcm "hw:3" channels 1 }
}
bindings [
{ slave a channel 0 }
{ slave b channel 0 }
{ slave c channel 0 }
{ slave d channel 0 }
]
}
}

I don't know, but using 4 mics as one virtual sound card, without sync, leads to nothing. Maybe this is useful: http://kokkinizita.linuxaudio.org/linuxaudio/zita-ajbridge-doc/quickguide.html I don't know, but you at least need some kind of hardware sync or software resampling. -- Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
