Audio Interfaces Tested For Screenflow 6

As Craig and the team have said that it's impossible to test audio interfaces and qualify them then I thought I'd start a list of those tested with results. Please add any that you test and say if they work or don't, or do with some issues.

    I just started using my RME UFX with SF 6.2 and it seems to be ok. That's why I reported it as such above. I'm using loopback in TotalMix and recording everything from the RME/UFX device inside SF. I'm not recording system audio. The sound is fine so far. The only problem that I have is that the stereo pair that is mixed out of my RME gets interpreted as two mono channels inside SF and they are not panned R/L. This results in much higher audio levels that in my case real clipping or "overs". However, keep in mind that I don't necessarily see this as an RME-specific problem. At least not yet.

    Avi Ziv That may depend on whether the device is sending a muxed dual mono channel or two separate channels. If the latter, ScreenFlow may see it as two center panned mono inputs.

    Maik Winter It may depend on how device interacts with Logic Pro. Have you tried recording straight into ScreenFlow as a source without any other software open (just record the desktop for video)? Also make sure you're monitoring through the computer's headphone jack and not a USB device (don't monitor through the BabyFace for example).

    CraigS Agreed - this is spillover from our discussion in the other thread. I won't perpetuate it here. I still think that the RME UFX works ok in SF.

  • CraigS It is not only Logic related. Any audio recorded using Baby Face Pro connected through USB creates audio distortion in Screenflow. Once unplugged Screenflow works fine. Fix would be much appreciated as I wanna use my mics for voice recording.

    How are you monitoring?

  • CraigS Not sure where you are heading? I don't understand how an answer to that would be relevant for a solution of the problem? Could you explain?

    Maik Winter Monitoring through a USB device while recording can result in audio problems.

    Maik Winter pending the results of Jonathan's suggestion it may simply be incompatible with ScreenFlow. I assume you're using their driver 2.20 and not 3.01 since you're still on OS 10.11.6 correct?

    Like
  • CraigS 10.11.6 on OS X and Driver 2.20 on BF yes. Talked to RME Support today. He didn't know about Screenflow (I explained) but he was not interested in diving into this issue. I explained what I researched in this forum. He just muffled he doubts that Class Compliant Mode would help (without knowing details on the issue). Well, kinda makes me think about selling that audio interface (even though the quality is awesome on recording).

     

    I still gotta try this CC Mode, but busy on other projects for now. Will update here when I tried it.

     Maik Winter I'm using RME Fireface UFX in loopback mode and screencasting Logic X. My RME is the hub of all my audio, monitoring, mixing in TotalMix - everything. I control my mix and have  SF record from the UFX and not from the computer audio stream. I'm not entirely clear about the distortion that you are experiencing but at last in my setup, SF reads in the UFX output pair as mono signals and has them both panned to the center. This causes major clipping distortion and an incorrect stereo mix. We can get around it (for now) by changing the pan of the audio channels inside SF to be R/L. You may want to check whether this is applicable to you. Once I have the channel pan correct in SF, the audio is fine as proven by exporting from SF and importing back to Logic X for evaluation and measurements. I understand that our devices (although closely related) are not the same but maybe this is of some help?

    Maik Winter Since it seems to work in Logic Pro but not ScreenFlow can you try one more test. Try recording audio directly into Quicktime X and tell me what that sounds like.

  • Maik Winter I used mine successfully in CC mode - which was a suggestion from RME support! It's a workaround.

    Like
  • Thanks Craig, Avi, Jonathan for all your suggestions. I think I found a workaround for my purpose. When I switch System Prefs > Sound > Output from Babyface to Internal Speaker (or Heaphones when connected) (Input still on Babyface) then SF records mac audio as well as my mics audio from Baby Face as intended.

    Granted, I can't hear my own voice during recording (I'm listening through headphones connected directly to MacBook, and lift one side of the headphone to better hear my voice), but at least I can monitor and adjust volume on a second screen using Totalmix. 

    When done SF recording I switch System Pref > Audio > Output back to Babyface and I have full control for post. 

     

    add on: it works on SF 6 and also on SF 4.5.2

    Maik Winter Yes, that's why I mentioned monitoring from the computer headphone/line jack. Monitoring from a USB device while recording from a USB device is a problem.

    Maik Winter no problem.

  • I can add the Behringer U-phoria UMC404HD to the list of audio interfaces that ScreenFlow recognizes as having four channels. It defaults to panning all to the center.

    What I am using this for is so that I can bring the mic in on input 1, and stereo from the audio gear on inputs 3 & 4. So my workflow is to extract all audio tracks, mute or delete the original audio track, delete audio track 2, re-pan track 3 hard left, re-pan track 4 hard right, and link together audio tracks 3 & 4.

    That's a lot of futzing around to perform on every recording (take) for every project. (I create one project per movie per Lynda.com training course, so we're talking typically 20-40 SF projects per course. My next one will have close to 50 projects/movies.)

    Then, in an ideal world, when I render (to send to Adobe Premiere Pro), input 1 would go on its own mono track, and 3&4 go on their own stereo track.

    But when I render from SF, my only options for audio - when I'm allowed to edit it (editing is disabled for the Lossless Audio Only preset) - is either mono or stereo. So I have to render twice, muting tracks as needed between renders.

    (As it turns out, I need to render twice anyway, as I'm recording webcam and computer screen as well with SF, and need them as separate streams when I get to Premiere.)

    On the one hand, it's great that I can use SF to record 2 video streams (one a screen capture) and 4 audio streams all at once.

    On the other hand, you would think this all could still be streamlined somehow.

    Chris Meyer Do submit this entire workflow description along with a Feature Request. The developers need to see more about the needs of those doing high volume workflows involving multichannel audio,

  • CraigS Quick question (before I file a bug report): Part of my workaround workflow requires muting whole channels when I render, so I can render one movie with the voice and one with the music. But when I was testing last night, whole track audio muting (not just segment, but the speaker and video icons along the left edge of the sequence window) did not seem to be working - the waveform graphics were grayed out, but audio still played from those tracks. Is this a known bug in the most recent version? It used to work...
