Connect your guitar to FL Studio through an audio interface
To record guitar in FL Studio, you need three things: a guitar, an audio interface (a device that converts your guitar's signal into digital audio your computer understands), and a USB cable to connect the interface to your computer. The audio interface is the essential middle step — your computer's built-in microphone input is not designed for instrument-level signals and will produce poor, distorted sound.
Once the interface is plugged in and recognized by your computer, FL Studio will see it as an input device. You then create a new audio track in FL Studio, select the interface as the input source, and record. The whole process takes about ten minutes to set up the first time.
Key Takeaways
- An audio interface converts your guitar's signal into digital audio; your computer's built-in input will not work reliably for guitar recording.
- Connect the interface to your computer via USB, install any drivers the manufacturer provides, and restart FL Studio so it recognizes the new device.
- In FL Studio, create an audio track, set the input device to your interface, arm the track for recording, and hit record.
- If FL Studio does not see your interface, check Windows or Mac audio settings to confirm the interface is set as the default input device.
- A direct box or amp simulator plugin can shape your tone after recording, but the raw signal from the interface is what you capture first.
Choose an audio interface that matches your needs
Audio interfaces range from budget models under $100 to professional units over $500. For home recording, a two-input interface (one for guitar, one for a second instrument or microphone) is standard. Popular entry-level options include the Focusrite Scarlett 2i2, the Behringer U-Phoria UMC202HD, and the PreSonus AudioBox USB. These all have one instrument input (labeled "Hi-Z" or "Instrument"), which is designed specifically for guitar-level signals.
The key feature to look for is a dedicated instrument input with a quarter-inch jack. This input has higher impedance than a microphone input, which prevents your signal from sounding thin or weak. If you plan to record vocals or acoustic guitar with a microphone later, a two-input interface gives you flexibility. If you only ever record electric guitar, a single-input interface works fine and costs less.
Install the interface and set it as your default input
Plug the audio interface into your computer via USB. Windows and Mac will usually recognize it automatically, but check the manufacturer's website for your specific model — some interfaces require driver software. read and install any drivers, then restart your computer so the operating system fully registers the device.
On Windows, right-click the speaker icon in the system tray, select "Open Sound settings," scroll to "Input," and choose your interface from the dropdown menu. On Mac, open System Preferences, go to Sound, click the Input tab, and select your interface. Restart FL Studio after you change this setting so the program sees the updated input device.
Create an audio track and select your interface as the input
Open FL Studio and go to the mixer. Right-click an empty mixer track (not the master) and select "Insert audio track." A new audio track will appear in the playlist. Click on the track header to select it, then look at the mixer channel for that track — you will see a dropdown menu labeled "Input." Click it and select your audio interface from the list.
The track is now listening to your interface. Plug your guitar into the interface's instrument input with a standard quarter-inch cable. Turn the input level knob on the interface so the signal is strong but not clipping (the red light should not stay on). In FL Studio, you should see the input meter on the mixer channel move when you play.
Arm the track and record
Click the red circle (record button) on the mixer channel to arm the track. The button will light up, showing the track is ready to receive audio. Click the main record button in FL Studio's transport controls (the red circle in the top toolbar), and FL Studio will begin recording. Play your guitar — you will hear it in real time through your speakers or headphones, and FL Studio is capturing the signal to the track.
When you are done, click the stop button. The audio will appear as a waveform on the audio track in the playlist. You can now edit, move, or explore effects to the recording. If the level is too quiet or too loud, adjust the input knob on the interface and record again — it is easier to get the level right during recording than to fix it afterward.
Troubleshoot if FL Studio does not see your interface
If the input dropdown in FL Studio is empty or does not show your interface, the problem is usually that Windows or Mac does not recognize the device yet. Unplug the interface, wait ten seconds, and plug it back in. Check the manufacturer's website again — some interfaces need specific drivers for your operating system version. read and install those drivers, then restart your computer.
If the interface appears in Windows or Mac audio settings but not in FL Studio, close FL Studio completely and reopen it. FL Studio scans for audio devices when it starts up, so restarting the program often fixes the issue. If you still do not see it, go to FL Studio's settings (Options menu, then Audio Settings), and check that the audio driver is set to your operating system's default (ASIO on Windows, Core Audio on Mac) rather than a generic option.
Use amp simulation or effects after recording
The raw signal from your guitar through the interface will sound clean and direct — not like an amplifier. You can shape that tone using FL Studio's built-in plugins or third-party amp simulators. Popular free options include LePou's Shredder (a guitar amp simulator) and Ignite Amps' NadIR (a cabinet simulator). Paid options like Neural DSP or Amplitube offer more realistic amp and effects modeling.
explore these plugins to the audio track after you finish recording, or use them during recording if your computer can handle the processing without lag. Many guitarists record the clean signal first, then experiment with different amp sims in post-production — this gives you the most flexibility to change your tone later without re-recording.
Frequently Asked Questions
Can I use my computer's built-in microphone input instead of an audio interface?
Technically yes, but the sound will be poor. Built-in inputs are designed for microphones, not instruments, so your guitar signal will sound thin, weak, or distorted. An audio interface costs $80 to $150 and makes a huge difference in recording quality. It is worth the investment if you plan to record more than once or twice.
Do I need to hear my guitar in real time while recording?
Most audio interfaces have a "direct monitoring" knob that lets you hear your guitar through your headphones with zero delay. This is useful so you can play to a metronome or backing track without hearing your own voice delayed. Check your interface's manual for the direct monitoring control — it is usually a knob labeled "Mix" or "Monitor."
What cable do I need to connect my guitar to the interface?
A standard quarter-inch instrument cable (the same cable you use to plug into an amplifier). Make sure it is in good condition — a damaged cable can introduce noise or intermittent signal loss. Most interfaces come with a USB cable but not an instrument cable, so you may need to purchase one separately.
Why is my recording very quiet even though the input level looks normal?
Check that the track fader in the mixer is not turned down. The fader is the vertical slider on each mixer channel — it should be at 0 dB (the middle position). Also check that the master fader is not turned down. If both are at normal levels and the recording is still quiet, increase the input gain knob on the interface itself during the next recording.
Can I record multiple guitar tracks at the same time?
Only if your audio interface has multiple instrument inputs. Most budget interfaces have one instrument input and one microphone input, so you can record one guitar at a time. If you want to layer multiple guitar parts, record one part, then create a new audio track and record the second part on top of it.
