[linux-audio-user] recording jack input

[Garett Shulman]

Hello, perhaps this rediculous and non-sensical... I have an audio 
application outputing sound to the jack input client 
alsa_pcm:playback_1. This is a physical playback device on a soundcard. 
In addition to playing this back out of the sound card I would also like 
to record it to a wav file on the hard drive. Does anybody have any 
ideas for doing this. Perhaps a third jack client that has an input and 
an output and just writes anything from the input to the output. Then I 
could connect the audio application to the input and alsa_pcm:playback_1 
and a recording application to the output. I guess ecasound could do 
this pretty easily. Is this the best way to acomplish the goal? There 
isn't any sort of 'loopback' output for jack input clients is there? 
Thanks! -Garett
