I’ve got two weird things happening when recording my guitar through some pedals including a loop pedal into an audio interface connected to my laptop via USB.
Guitar into pedals into Fender amp then line out to audio device with USB cable to laptop.
When I play guitar, which passes through the MXR Clone Looper pedal through the amp to the Behringer UM2 audio interface box then to the laptop running Audacity recording software, I get the guitar signal and it records just fine.
If I talk while recording, this also shows up on the recording loud and clear. I’m thinking my laptop mic must be on and is picking up my voice - I’ll test this out later tonight. At least I can get vocals into my recording without springing for a mic to hook into the other channel of the audio interface box, although it’s most likely not a high quality.
The weirder thing. Although my guitar records fine, if I hit the playback on my loop pedal, which goes through the exact same cable path as the guitar (to the amp, out the line out to audio interface box, then to the laptop via USB.), IT DOES NOT REGISTER ON THE METERS IN THE AUDACITY SOFTWARE AND DOES NOT RECORD! Even though the clip light is flickering on the audio interface box so I know the box is getting the signal (and I can hear it on the headphones connected to the audio box). It just doesn’t seem to pass this through the USB to the laptop. But it comes into the audio interface box through the same cable from the amp that the guitar signal comes through.
I’m sure there is an explanation but I have no idea what it could be. In theory, any signal going to the amp where I can hear it on the amp should go out the line out (which it is cause I see the clip light flickering on the audio interface) and through the audio interface to the USB out -the guitar does but the recorded loop of the guitar does not…
I meant the green signal light on the UM2. So I checked again and I was using the computer mic, I changed mics to the "Microphone (2 - USB Audio CODEC), but now no signal in Audacity. I do have 2 (Stereo) Recording Channels selected.
When I go to the Windows Sound Control Panel, I did have to change to 2 Channel 16bit 48000 Hz, then I can see the meter move in the Windows Start Test when I strum the guitar. So I know Windows is receiving the audio signal through the USB connection.
But when I restart Audacity and try to record, nothing.
Hey I saw this post from Feb and followed it exactly (except it’s 16 bit not 6 bit). I had mine set up this way - closed Audacity and reopened - but still no signal from guitar playing in Audacity although I can see the signal on meters test in Windows Sound Comtrol Panel.
I don’t record anything on this laptop and have not used Zoom in weeks - don’t use anything else.
Plug the UM2 in and make sure the Power light on the front comes on.
Right click the Windows Speaker icon > Recording devices. Find the right one. I don’t know any handy spells other than it’s going to mount as USB Audio CODEC.
Select it > Properties > Advanced: Default Format Dropdown: 2-Channel, 6-bit, 44100. > Apply > OK.
Launch or Relaunch Audacity to reset its internal device count.
Microphone setting in the menu bars: Microphone (USB Audio CODEC), 2 (Stereo) Input Channels.
Click the Audacity recording meters to start monitoring (without actually going into record). Tap, scratch or speak into the microphone (Never Blow) and the sound meters should jump.
If you set up for dual channel, your voice will be on the Left and the guitar on the Right. It’s the only way to record guitar.
So look at my second post above at 9:17, I had been recording from the laptop mic accidentally do that explains why it recorded the guitar sound (from the actual strings and not the USB connection), and also explains why I was recording my voice as I did not have a mic hooked up to the UM2 for voice.
So changed the mic in Audacity to the USB mic, made sure I selected Stereo recording, and changed the setting in Windows to 2 channel 16 bit 48,000 (and also tried 44,100) Hz, per the instructions from another post on here.
After doing this - I get a meter reading on the Windows Sound Control Panel for testing the mic when I strum guitar, and I get no reading from talking, and it’s the USB mic selected so I know it is not the laptop mic. This means I am getting a signal from the USB cable connected to the UM2 when I stream the guitar.
However, when I then open Audacity and click the meter to monitor - and also if I try to record a stereo track, there is no reading it all from guitar strumming and no sound at all when I play the track - flat line and dead silence.
OK two screenshots. One of the original recording while strumming the guitar and showing the amplify affect settings about to be applies. The other with the amplify affect applied. It just sounds like scratchy noise.
I should add that the headphones connected to the UM2 play the sound loud and clear. The UM2 was bought new in the fall. And although I have had them connected to USB cable to my laptop, I have not been successful in recording from it, but I do see the signal meter from Window Control Panel for Sound, as I’ve noted above and included screenshots.
OK I just found out that I can plug my 1/4" guitar plug into the Instrument 1 of the UM2. I didn’t realize that before but just saw it on a YouTube demo of the UM2. Now it records the guitar. And I can change it to Mono recording and record the single track in mono, like it should be for guitar. I guess this works for now until I get a mic and want to simultaneously record vocals and guitar or vocals and keyboard.
If you can suggest something to get the Instrument 2 channel working to record from the UM2 that would be great. Incidentally I checked the same Windows Control Panel Sound mic tests for the Instrument 1 connection to UM2 and the levels are showing exactly the same for Instrument 1 and Instrument 2. Something is blocking the Instrument 2 channel when I get to Audacity to record it.
By "Set the default format to “stereo”, I assume you mean to 2 channel 16 bit 48,000 Hz, which is what it was set to already when I followed your instructions - as I had already done this in a previous step and is shown in one of my screen captures in a response above.
I followed your instructions, but still the same behavior:
In the Windows Control Panel for Sound - I can see the meter moving in the “Test your microphone” bar, when I have the guitar plugged into Instrument 2 and strum it.
In Audacity, I have “2 (Stereo) Recording Channels” selected, but when I click “Click to Start Monitoring”, it does not show any movement when I strum the guitar. I have the Instrument 2 Output knob turned almost all the way up on the UM2, and as I say I can see the bar moving when I test microphone from Windows Control Panel, but not from Audacity.
Weird huh? It’s like Windows recognizes the Instrument 2 input from UM2, but then Audacity does not. I wonder if there is a 3rd independent utility I can use to verify if Windows recognizes the audio input from the Instrument 2 (channel 2) coming from the UM2?
