Audio from DV stream through firewire

Post by badEnough » Wed Apr 20, 2011 3:11 pm

Hello,

Is there any mean to record audio incoming through firewire as part of a DV stream?

Various video editing programs cand do this, sometimes it is called "voice over recording". Some video cameras have a more-than-decent audio quality (though limited to 48 kHz 16 bit) and provide phantom power.

I wonder if Ableton Live as anything built-in... or maybe anybody here is aware of some software driver (ASIO compatible or not) which would permit to just see a new audio device.

I found this page for Mac users, but I am on a Windows PC

(anyway, these solutions do not seem to me to be extracting the digital audio stream from anywhere, instead they seem to be "capturing" by reconverting to digital what's eventually being monitored, using the AD converter of the computer hardware: "if you can hear it..."):

The monologue is getting to an end for now, I think, just sharing some info:


Apart the capture function of Adobe Premiere (it has a "capture audio only" choice in a handy listbox) and Canopus Edius (Sony Vegas too I guess), I found this page:

which brings to:

----------

I haven't tried anything yet, I don't think any of these options can reproduce anything from a timeline while "capturing" on it as a "voice over" function would do (Premiere, Edius and Vegas could well have such function, Final Cut does but by now I hate and despise Apple).


One way to record in a "parallel" track synced with any audio clip which we can't reproduce from the same piece of software which is making the recording would be to put some sound markers at the beginning end ending of the timeline, output the timeline, reproduce it with a separate player to headphones, record the sound markers from the headphones to the mic, play/talk/sing/whatever while listening through the headphones, move the newly recorded clip (of course with the one we were listening to through the headphones) to Ableton Live and use its warp function to have the sound markers aligned.


OF COURSE if Ableton Live was able to extract the audio part of a DV stream OR if we had any software driver (*) capable of turning a DV stream input into an audio device, THEN a much simpler workflow would be possible (id est just reproduce+record in Ableton Live, apply effects, do another take if we don't like...).

(*) A nice but not indispensable feature would be variable time shift for compensation of the relatively great latency intrinsic to the chain involved (video camera => DV stream). I don't know if such thing would ever possibly become an ASIO compliant device, that would be great but the opposite wouldn't be an issue, thanks to the warp feature of Ableton Live.
