How to Record MP3 on Windows 11: A Step-by-Step Guide

By / September 18, 2025

Need to record audio on your Windows 11 PC—whether it’s your voice, a lecture, a podcast, or meeting notes? The best way is to record directly into the MP3 format, since it’s lightweight, universally supported, and easy to share.

But here’s the challenge: Windows 11 doesn’t include a built-in MP3 recorder by default. Instead, you’ll need to use either Microsoft’s apps, free third-party tools, or online services.

In this step-by-step guide on how to record MP3 on Windows 11, we’ll explore every method, from using the built-in Voice Recorder app to advanced recording software. By the end, you’ll know how to record, edit, and save your audio in MP3 format—quickly and easily.

Why Record in MP3 Format?

Before diving into methods, here’s why MP3 remains the go-to audio format:

  • Small file size → Perfect for saving storage space.

  • Universal compatibility → Works on PCs, smartphones, and media players.

  • Good quality-to-size ratio → Clear sound without massive file sizes.

  • Easier sharing → Email, cloud, or messaging apps all support MP3.

Think of MP3 as the “JPEG of audio”—compressed, portable, and widely used.

There’s more than one way to capture audio on Windows 11. Here are the most common:

  1. Voice Recorder app (with MP3 conversion)

We’ll cover each method step by step.

  2. Open the app.

  3. Click the microphone button to start recording.

  4. Press Stop when finished.

  5. Your recording is saved automatically in M4A format under:

Documents > Sound recordings

Convert to MP3:

Use a free converter:

This method is simple for beginners.

Method 2: Recording MP3 with Audacity (Free Software)

Audacity is a powerful, open-source audio editor perfect for MP3 recording.

Method 3: Use Online Audio Recorders

If you don’t want to install software, online tools can help.

  2. Allow microphone access.

  3. Click Record, then Stop when done.

  4. Save the file as MP3.

⚠️ Note: Internet connection required, and privacy may be a concern for sensitive recordings.

Method 4: Use Professional Recording Software (DAWs)

If you’re into music, podcasting, or professional recording, DAWs are ideal.

Popular DAWs:

  • Adobe Audition

  • FL Studio

  • Reaper

Steps (Adobe Audition Example):

  1. Open Adobe Audition.

  2. Create a New Audio File.

  3. Select MP3 format as the recording output.

  4. Press Record to start.

Method 5: Record MP3 with Screen Recorders

Some screen recording apps let you record audio only and save as MP3.

Tools:

  • OBS Studio (free)

  • Camtasia (paid)

Steps (OBS Example):

  1. Install OBS Studio.

  2. Add an Audio Input Capture source.

  3. Start recording.

  4. Stop recording when done.

  5. Convert to MP3 (OBS usually saves in MKV/WAV, so convert via VLC or Audacity).

This is best if you want to record system audio + microphone together.

Advanced Tips for Better MP3 Recordings

  • Use a good microphone → Even a budget USB mic improves quality.

  • Record in a quiet room → Avoid background noise.

  • Adjust input levels → Too high = distortion, too low = inaudible.

  • Edit before saving → Trim silence, normalize volume, reduce noise.

  • Choose the right bitrate →

    • 128 kbps = Standard quality

    • 192 kbps = Better for speech

    • 320 kbps = Best for music

Common Problems and Fixes

1. Recording has no sound

  • Check if the microphone is enabled in Settings > System > Sound > Input.

2. File won’t save as MP3

  • Install Audacity with LAME encoder or use VLC converter.

3. Background noise in recordings

  • Enable Noise Suppression in software.

  • Use a pop filter for clearer audio.
