I am having problems with the recording level on Audacity. I had no problems on my previous lap top, but now I have change to a LENOVO ThinkPad X1 running Windows 10, I cannot get a good recording level. It is way to quiet.
Upping the instrument’s volume just results in distortion. I am using a Blackstar ID Core 20 as an input device for recording guitar, both electric and acoustic with a USB connection. I am using the Insider app for the amp as updated Architect app does not register.
Also, only one of the USB ports will allow audio input but both show that the ID CORE is connected. Anyone got a solution.
The ADC (analog-to-digital converter) is inside the amp and you normally have to adjust/control the analog volume before it’s digitized.
You can boost after recording with the Amplify effect but if it’s WAY to low there could be other issues.
Does turning-up the amp make the recording louder?
I am using the Insider app for the amp as updated Architect app does not register.
Does either of those have a recording volume control? That might be how the analog level into the ADC is supposed to be controlled.
Did the Architect app work on your old computer?
Also, did you read this part on pager 18 of the ID Core Handbook:
USB Recording Level – Tap + Gain
As stated in the USB Audio section (see page 15), the output level of the USB audio
signal from your ID:Core amplifier can be controlled independently of your amplifier’s
speaker volume by holding down the Tap switch (11) whilst turning the Gain control
(3) on the front panel.
I hope this helps. 
Thanks for all the information. I think you have pointed me in the right direction…
RTFM! (Read the…manual!)
I will get back to you if I get no joy from pressing tap and twisting gain!
Yes. Hopefully you won’t have to contort you whole body to do that. 
Check the Device Toolbar in Audacity to ensure the correct recording device is selected. Adjust the Recording Levels in Audacity. You can do this by moving the slider with the microphone icon in the Recording Meter Toolbar. Windows Sound Settings: Go to the Sound Control Panel, select the Recording tab, and ensure the levels for your device are set appropriately. You might also want to increase the Microphone Boost if available. Ensure that you have the latest version of Microsoft’s .NET Framework installed, as it’s required for the Blackstar software to function properly.

If you’re having trouble with the Blackstar Insider app, try uninstalling it, restarting your computer, and then reinstalling it. If that doesn’t work, you could try installing an older version of the Insider app. For the USB connection issue, it’s possible that there’s a problem with the USB drivers on your laptop. Make sure all your USB drivers are up to date.
I attempt to record guitar, whether electric or acoustic, I ve an intermittent feedback loop that causes unpredictable volume spikes and distortion. It’s like the amp and Audacity are locked in some strange battle for control! While both USB ports on my laptop recognize the ID Core 20, only one allows for stable audio input.
