Hi,
Sorry bad english, ok? rsrs

I'm using windows 7 and a have to make a job when i need recorder some audios. I make 3 virtualbox with windows xp.
But i can not separate audios from virtualbox and my OS.

When i start any audio, all of them mix...

How can i recorder and make this audios be "alone"...to be separated?

Thanks!

What exactly do you mean by "separated"? Ultimately, all audio-in comes from a single "Line-in" input on the host. You don't have separate inputs therefore there is nothing to separate.

For example:
Virtualbox1 - I want play youtube video and recorder sound.
Virtualbox2 - I want play online radio and recorder sound.
Virtualbox3 - I want play online music and recorder sound.

But it's 3 sounds have to be separated, and i have to recorder simultaneously.

My final job is recorder radios, but streamings are .m3u8 and i don't know any program shedule and record for streamings links

FWIW, the word you are looking for is "record" not "recorder". :)

What program or programs are you using to record the audio from the three sources? You can record the audio separately although I don't know how or why you want to record them simultaneously. It's not a VirtualBox question btw.

I don't know that Virtualbox passes audio to a guest from the line-in on a host - never heard of being able to do that. So if you're trying to record in the guest from a source playing on the host, I don't think that will work.

Audio does play from the guest into the host. But all guests play into the line-out on the host, there is no way to separate them in Virtualbox, best as I understand. So if you want three guests to play different audio and record them in three separate recordings, you'll have to record in the guest as well as play. There is a program that transfers audio onto a network, but for the life of me I can't remember what it's called. (try searching for "Audio over Ethernet open source") If you can get your guests to feed audio into the virtual network cards, you may be able to get separate recordings from three recorders running on the host.

I don't believe that's what he wanted. Everything he mentioned recording is from an online source. So one can certainly run three guests and record a different online source. Doing that simultaneously is a different question. I'm not sure his question is clear.

I'm not an audio user myself (rather, I don't record from a sound card), but I've noted the devs mentioning around here in the past that recording from LINE-IN is supported. The important thing to note is that recording from MIC-IN is not supported. However, as Lou points out, it looks like that issue is a red herring anyway.

I'm not sure what the OP has in mind. I can open three browsers at the same time and record the audio from each on one host. The language barrier is going to be a problem.

Loukinggjr: I'm using Playit Recorder in each virtualbox for shedule and record audio from online radios.
"I don't believe that's what he wanted. Everything he mentioned recording is from an online source. So one can certainly run three guests and record a different online source. Doing that simultaneously is a different question. I'm not sure his question is clear." Exctly!!!!!!

no need to apologize for your English. You should hear mine and it's my first language. :D

Well if you can have three guests open at once there doesn't seem to be any reason you can't record different sources and based on what you said before, it's the playback that mixes through the host. If it's just a question of not wanting to listen to them at once you can always mute the audio in the guests you don't want playing.

Thanks for support (:

i can't put mute because i have to record all of them 24h and make monitoring. listen all and separate some notices and musics. Compare genre of news...etc.
I do not care to hear them at the same time as they record , just need the separate audio when the file is generated

Welcome. Muting the guest should only mute the output. It would still be recording. However, you would have three separate audio files not one. And short of running all the guests through a mixing board i can't see how you could edit the files in real time.

"However, you would have three separate audio files not one." i want exactly it, but with sounds separated. each virtualbox with one radio.
and about edit...i will edit just when the file be generated.

If you are recording on three separate XP guests, you end up with three separate audio files. The sounds aren't mixed unless you play them all back at once.

Think of the guests as three different computers. How would you do what you want with three different computers?
