How to Record Video and Audio from Webcam and Microphone Simultaneously?

Updated: April 2026

Recording Webcam and Microphone — The Easy Way

Whether it's a quick video message, an online-course segment, or a remote interview, capturing webcam footage with synchronized audio doesn't require heavyweight editing software. Windows' built-in Camera app, a free tool like OBS Studio, or an online recorder such as DoCam.io can each get the job done in under a minute.

1. Check Your Equipment

  1. Make sure your camera is connected and recognized by the system.
  2. Verify that your microphone is working (the activity indicator should move when you speak).
  3. Visit DoCam.io to test both devices without installing any software.

2. Recording Using Built-in Tools on Windows and macOS

Windows 10/11

  1. Open the Camera app.
  2. Select Video mode.
  3. Press Record.
  4. Audio is automatically recorded from the default microphone.

🍎 macOS

  1. Launch QuickTime Player.
  2. Go to File → New Movie Recording.
  3. In settings, select your camera and microphone.
  4. Press the record button.

Tip: If audio isn't recording — open System Preferences → Sound → Input and select the correct microphone.

3. Recording with OBS Studio (Professional Option)

OBS is a free program that allows you to simultaneously record video, audio, and even the screen.

  1. Download OBS Studio and install it.
  2. Create a new Scene.
  3. Add sources:
    • Video Capture Device → select your camera.
    • Audio Input → select your microphone.
  4. Click Start Recording.

OBS Advantages:

  • Recording without watermarks.
  • High quality and multi-channel audio.
  • Customizable frame (resolution, FPS, compression).

4. Online Recording Without Installing Software

If you don't want to install software — use browser-based solutions:

  • DoCam.io — online camera and microphone testing and recording.
  • WebCamera.io — simple online recorder with MP4 saving.
  • RecordCast — record camera and screen simultaneously.

Important: In browser, you must grant access to camera and microphone ( → Allow).

5. Tips for Improving Quality

  • Use headphones — this eliminates echo.
  • Position the camera at eye level and ensure soft lighting from the front.
  • Check your microphone before recording (volume level and background noise).
  • Record video in 720p or 1080p — optimal for stable performance and file size.

Start Recording

That's really all it takes. A webcam recording can be up and running within seconds using any of the methods above. The one step you should never skip: test your camera and microphone first so you don't discover a muted mic or dark video after finishing a 30-minute session.

Verify your camera and mic are working perfectly on DoCam.io.
