Windows 11 Voice Recorder: Export MP3, M4A, WAV

The Sound Recorder app in Windows 11 includes native support for multiple audio formats, allowing users to record and export files directly in M4A, MP3, and WAV. By configuring the app’s internal settings, you can define your preferred file format prior to recording, eliminating the need for third-party conversion tools.

How to Select the Export Format in Windows 11 Sound Recorder

Windows 11 saves recordings automatically in the format selected within the app settings. To choose between M4A, MP3, or WAV:

  1. Open Sound Recorder: Press the Windows key, type Sound Recorder, and press Enter.
  2. Access Settings: Click the Settings icon (the gear icon) located at the bottom-left corner of the application window.
  3. Change Recording Format: Locate the Recording format option in the settings menu.
  4. Choose Your Format: Click the dropdown menu and select your desired format:
    • M4A (AAC): Best for balanced file size and standard quality.
    • MP3: Ideal for universal compatibility across devices and platforms.
    • WAV: Uncompressed format suitable for high-quality editing and archiving.
  5. Adjust Audio Quality (Optional): In the same menu, adjust the Audio quality setting to prioritize either smaller file sizes or higher fidelity.

Recording and Saving the Audio

Once the format is selected, return to the main interface:

  1. Click the red Record button (or press Ctrl + R) to begin recording.
  2. Click the Stop button when finished.
  3. The recording is automatically saved in your selected format (M4A, MP3, or WAV).

Locating Your Exported Audio Files

To access the physical audio files on your computer:

  1. In the Sound Recorder app, right-click any recording in the left-hand list and select Open in File Explorer, or click the three dots (…) at the top right of the selected clip and choose Show in folder.
  2. Alternatively, open File Explorer manually and navigate to: C:\Users\<YourUsername>\Documents\Sound Recordings

All files in this directory will reflect the extension (.m4a, .mp3, or .wav) designated in your settings at the time of recording.
