USB B LIVE STREAMING

Qu Qu Troubleshooting
1

Hey, all, been searching for a solution to my issue, hopefully someone can help. During this quarantine period I have been trying to live stream to facebook using my Qu-Pac as an audio interface via usb-b, for a microphone and acoustic electric guitar. Although I can get the audio to pass through to my computer and be recorded by facebook, the audio sounds washed out, or like you were listening through a cone, and the levels seem fight each other.

I have assigned my ch1 and ch2 to “L+R Pre” in the I/O patch tab and am using Firmware 1.95 - Rev 4561.
I am using a Mac with an i7 processor and 32gb of ram on MacOS Catalina and connected via usb-b cable.
In setting I have Qu Pac assigned for input and output, and in Utilities under Midi Audio I have channels 22 and 23 set for my output chanels.

Is there a setting i’m missing or has anyone had issues trying to do the same and were able to resolve them?

Thanks in advance for any help. I tried to provide as much relevant info as possible, if i missed anything let me know.

What sort of room are you in? Are you sure it is not the room doing it?

What EQ and compression are you adding?
Any special F/X too ?

What DAW are you using? What does the freq spectrum look like in the DAW?
Can you tweak things there before you upload to FB?

I’m not recording to a DAW, I’m going live on Facebook and using the QuPac as my audio interface.

As far as FX, I have reverb for vocals on FX1 and Reverb for guitar on FX2 and using slight compression on both channels.

I’m new to live streaming and figured the Qu Pac would be great to use to get the great sound I have live in a live stream.

Also, I’m in my living room and the guitar is plugged directly into a DI Box and into the desk, and the microphone is wireless but plugged direct into desk as well.

5

did you have a piece of the stream as a recording?
so send it us…
so we can listen to it

did you time aligned the mic and the guitar? or tried reversing the phase on one…
since the mic is picking up guitar at the same time this could degrade the mix of both…

6

here’s an mp4 of just the guitar playing, you can hear how it seems to fluctuate in volume and tone. I did reverse the phase on the guitar channel, nothing changed

7

Mp4 was too big, lets try and mp3

8

SO I just tried recording through garage band and nothing cut out or sounded bad like it did on the live stream, which would lead me to believe that maybe the live stream web browser can’t handle the audio output of the qu pac? Not sure anyone have any thoughts?

9

at least we pointed the direction…

10

Unfortunately the direction is not any closer to a solution lol. Has anyone used the mixer for live streaming direct to the web with success before?

@Keithk2581

our church uses the Qu to livestream to utoob and it works well
maybe facebook is the problem

did not see any mp3 or mp4 here to evaluate

why not just post it after recording if garbageband works okay
what is so urgent that you need to livestream?

12

no rush other than wanting to stream live for the fun of it. The site wouldn’t let me upload a file because it was too large, can only be 1024kb. Best I can describe the problem is that it seems 1 channel fights the other for dominance.

13

@Keithk2581

Don’t see that being a Qu issue.

and still dont see any mp3/4 file to play to listen to

not sure what one channel fights the other means exactly;
MikeC pointed out how phasing could be a problem.
Do you have some compression or AGC confusing things.
Are you sure facebook is not the issue since your DAW worked okay?

I noted it could be the room effects, which is what your sounds like its in a cone says to me.

Keith and Alex from A&H did a live stream on their Facebook a week or so ago about how to “Live Stream” using the QU, here is the link and hope it helps.

I have assigned my ch1 and ch2 to “L+R Pre” in the I/O patch tab and am using Firmware 1.95 – Rev 4561.

When you say assigned ch1 and ch2 is that in the IO menu USB set up?

For Facebook process of elimination try these ideas…
-only use ch1 and un-assign every other USB track output, select the track block and scroll through till you get to the X, then hit apply.

-assigning ch1 L and ch2 R

Finally was able to make an mp3 small enough to post. Lee thank you for the you video link, can’t wait to watch it!

-Mike C - Yes i used the IO menu tab to assign those 2 channels.

-As heard in the mp3 file, even using just one channel was giving me the same issue.

_im going to try later your tips on X all of the other channels in the IO menu tab

17

Heres a small mp3 sample. Its only one channel, my guitar, but the same issue is present.

Thanks for the link to the video Lee7, can’t wait to watch it,

Mike C - Yes I used IO menu to assign those channels. Will watch the above video and try your suggestions later today, hopefully together they will resolve this for me.

Thanks to all of you who have tried to help me with this, it is truly appreciated.

sorry but there is no technical problem with the desk…

@Keith2581

Thanks.

I do not hear any problems with it by itself.
Even for mp3 it is good. Most mp3 sounds like crap to me.
It is far better than most mp3 andor audio on utoob.
Do not use facebook so can’t speak to them specifically.

So certainly not a Qu problem.
Is the bad sound only on facebook or can you hear it before you start uploading or streaming.

Could it be the other channel or when you have both of them that it is audible?
If possible can you upload a wav file with both together like you originally noted was a problem.
