How to Record Guitar on PC with Reaper DAW

This guide walks you through recording electric or acoustic guitar directly into your PC using Reaper, a free-to-try digital audio workstation. You’ll learn how to set up your audio interface, arm a track, record a clean take, and apply basic effects—so you can capture your playing with minimal fuss and decent sound quality.

What You’ll Need

• A PC (Windows, macOS, or Linux) with a USB port.
• Reaper DAW installed (download from the official site; it runs in full-featured evaluation mode for 60 days).
• An audio interface (e.g., Focusrite Scarlett, Behringer U-Phoria) or a USB guitar cable like the Rocksmith cable. A built-in mic won’t give good results for electric guitar.
• A guitar cable (1/4″ instrument cable) to connect your guitar to the interface.
• Headphones or studio monitors to hear playback without feedback.
• Optional: ASIO4ALL driver if your interface doesn’t have its own ASIO driver (Windows only).

Step-by-Step

1. Install and launch Reaper. Download the installer from the official Reaper site, run it, and accept the defaults. Open Reaper after installation.
2. Connect your interface. Plug your audio interface into a USB port and connect your guitar to the interface’s instrument input (usually labeled “Inst” or “Guitar”). Turn on the interface if it has a power switch.
3. Select your audio device. In Reaper, go to Options > Preferences (or press Ctrl+P). Under Audio > Device, set the Audio system to ASIO (Windows) or CoreAudio (macOS). Choose your interface from the ASIO Driver dropdown. For Windows without a native ASIO driver, select ASIO4ALL and configure it to use your interface. Click Apply and then OK.
4. Set up a track. In the main window, double-click in the empty track area to create a new track. Or press Ctrl+T. The track appears in the left panel.
5. Arm the track for recording. Click the red circular Record Arm button on the track. It should turn red.
6. Select the input. Click the track’s input button (the small icon that looks like a microphone or a plug). Choose Input > Mono > Input 1 (or whichever input your guitar is connected to). For a stereo DI, choose Stereo > Input 1/2, but mono is standard for guitar.
7. Set monitoring. Click the speaker icon (monitor button) on the track so it turns blue. This lets you hear the guitar through your headphones or speakers while recording. If you get feedback, use headphones.
8. Adjust levels. Play your guitar and watch the track’s meter. Aim for peaks around -12 dB to -6 dB. Turn the interface’s gain knob up or down until you get a healthy level without clipping (red lights).
9. Position the playhead. Click on the ruler at the top of the timeline where you want to start recording. The playhead (vertical line) moves there.
10. Record. Press Ctrl+R or the red Record button in the transport bar at the top. Play your guitar. When done, press Spacebar to stop.
11. Playback. Press Spacebar to play back your take. You should hear your recorded guitar. If not, check the track’s mute button and the master volume.
12. Add effects (optional). To add amp sims or effects, click the FX button on the track. Choose a plugin like a distortion or reverb. Reaper comes with several free effects (e.g., ReaVerbate, ReaComp). For amp modeling, you may need a third-party VST like Amplitube or Guitar Rig.
13. Export your recording. Once you’re happy, go to File > Render. Choose an output format (WAV or MP3), set the sample rate (44100 Hz is fine), and click Render to save your file.

Common Mistakes

• Input not selected: Forgetting to set the track input to your interface’s input. The track records silence.
• Monitoring off: Not enabling the monitor button, so you can’t hear yourself while playing.
• Clipping: Setting the gain too high, causing distortion in the recording. Keep peaks below -6 dB.
• Wrong ASIO device: Choosing the wrong driver in Reaper, resulting in no sound or high latency.
• Recording on the wrong track: Arming multiple tracks or the master track, which can cause confusion.

Tips

• Use a DI box: If your interface has only a mic input, a direct injection (DI) box converts your guitar’s signal to mic level.
• Keep a clean signal: Record without effects first, then add amp sims later. This gives you flexibility to change tones.
• Use a metronome: Enable the click track (press Ctrl+Shift+M) to keep your timing tight.
• Set a buffer size: Lower buffer (e.g., 128 samples) reduces latency but may cause clicks. Adjust in the audio device settings.
• Save your project: Save early and often (Ctrl+S) to avoid losing work.

Troubleshooting

• No sound from guitar: Check that the track is armed, the input is set to the correct channel, and the monitor is on. Ensure the interface is selected as the audio device. Test with a different cable or input.
• Latency (delay between playing and hearing): Lower the buffer size in the audio device settings. If it gets crackly, raise it slightly. Use ASIO drivers for best performance.
• Recording is too quiet: Increase the gain on your interface. If it’s still low, check the track’s volume fader and the input level meter.
• Distorted recording: The input is clipping. Turn down the gain on the interface until the meter stays below -6 dB.
• Reaper crashes on launch: Try resetting the configuration by holding Ctrl+Shift while starting Reaper. Reinstall if necessary.

Frequently Asked Questions

1. Do I need an audio interface to record guitar? Yes, for electric guitar. A USB interface or USB guitar cable is required to get the signal into your PC. Acoustic guitar can be recorded with a microphone, but that also needs an interface or a USB mic.
2. Can I use a USB microphone instead? Yes, for acoustic guitar or an amp. Plug the USB mic into your PC and select it as the input device in Reaper. For electric guitar, a USB mic won’t work directly.
3. What is ASIO and why is it important? ASIO is a low-latency audio driver protocol. It allows Reaper to communicate directly with your audio interface, reducing delay. Without it, you may experience noticeable lag.
4. How do I add effects to my recorded guitar? Click the FX button on the track, then choose a plugin from the list. Reaper includes several basic effects. For amp sounds, you’ll need a third-party VST plugin.
5. Can I record multiple guitar tracks? Yes, create additional tracks and repeat the steps. You can record different parts on separate tracks and mix them together.
6. How do I export my recording as an MP3? Go to File > Render, select MP3 as the output format, and click Render. You may need to set the bitrate; 320 kbps is good quality.
