Perhaps if you told us what you were trying to do, we might be of more help. Why in the world would you want to do that. Why can you not "mix" them afterwards, since the stuff going out your speaker surely originated from your computer anyway. > I think I should mix the mic with the speaker at first, then record the > mixed stream.

[snip] Huh ? How about recording a VOIP session - the stuff going to speaker originates in somebody else's computer. Regards, Sergei. |

But at least you have given me a clue as to what he might be refering to. (Ie, using it to record skype phone calls he is making). One possibility is to use jack to link up the pieces.

My use case is just add a backgroud music to my voice record. Thanks for you suggestion for JACK. But can i use "~/.asoundrc" or "amixer" to realize it? 2011/4/18 Bill Unruh <un...@ph...> > On Mon, 18 Apr 2011, Sergei Steshenko wrote: > > On Mon, 18 Apr 2011 00:29:20 -0700 (PDT) >> Bill Unruh <un...@ph...> wrote: >> [snip] >> >>> Why can you not "mix" them >>> afterwards, since the stuff going out your speaker surely originated from >>> your >>> computer anyway. >>> >> [snip] >> >> Huh ?

I have never used jack myself I am afraid. I just know that it is what is often suggested for doing the kind of mixing you are refering to. Again, it would seem that you could always add in the background music afterwards (or even if your system is playing the music it will come in through the microphone with your voice anyway.) > > 2011/4/18 Bill Unruh <un...@ph...> > >> On Mon, 18 Apr 2011, Sergei Steshenko wrote: >> >> On Mon, 18 Apr 2011 00:29:20 -0700 (PDT) >>> Bill Unruh <un...@ph...> wrote: >>> [snip] >>> >>>> Why can you not "mix" them >>>> afterwards, since the stuff going out your speaker surely originated from >>>> your >>>> computer anyway. >>>> >>> [snip] >>> >>> Huh ?

Surely if I use a speaker I can get the background music route back from mic. but there will be a very bad audio quality as i guess... So I want to use the headset and the mic, then there will be no music echo after I record the "mic" and "speaker" together. But how can I mix the mic and speaker together? I want to use "~/.asoundrc" or "amixer" or something like that... 2011/4/18 Bill Unruh <un...@ph...> > On Mon, 18 Apr 2011, cong fu wrote: > > My use case is just add a backgroud music to my voice record. >> >> Thanks for you suggestion for JACK. >> >> But can i use "~/.asoundrc" or "amixer" to realize it? >> > > I have never used jack myself I am afraid.
