What's Room Correction


Room correction is a process that involves adjusting the audio output of a sound system to compensate for the acoustic characteristics of a specific room, enhancing sound quality and accuracy.

The Benefits of Room Correction

  

1. Improved Sound Quality: Room correction systems analyze the acoustic properties of a room and apply adjustments to minimize negative effects such as echoes, reverberations, and standing waves. This results in clearer, more accurate sound reproduction.

 

2. Compensation for Room Acoustics: Every room has unique acoustic characteristics that can affect sound quality. Room correction compensates for these characteristics, adjusting the audio output to ensure that it closely matches the original recording. This is particularly important in rooms with hard surfaces or oddly shaped spaces that distort sound.

 

3. Enhanced Detail and Clarity: By correcting frequency response anomalies and time-based errors, room correction brings out the detail and clarity in music and audio content. This means you can hear each instrument and voice more distinctly, bringing you closer to a live performance experience.

 

4. Integration with Home Theater Systems: For home cinema enthusiasts, room correction ensures an immersive and balanced surround sound experience in home theaters. . It ensures that the soundstage is well-balanced and that effects move smoothly across the room, closely mimicking the experience of being in a movie theater.

 

5. Balanced Bass Response: One of the most challenging aspects of audio reproduction in rooms is achieving a balanced bass response. Room correction helps to even out the bass frequencies, reducing boominess and muddiness that can occur when bass waves interact poorly with room dimensions and furnishings.


In summary, room correction is a powerful tool for anyone looking to get the best possible performance out of their audio system. It customizes the audio output to match the specific acoustics of the room, ensuring a more enjoyable and accurate listening experience.

Room Correction vs. EQ


Room Correction and EQ are both powerful tools that serve different purposes. Room Correction is an automatic optimization tool that corrects room acoustics, while EQ is a manual adjustment tool for fine-tuning your sound. By combining both, you can achieve a more flexible, balanced, and immersive listening experience with WiiM audio devices.

Preparations for Room Correction


Before Calibration


1. Ensure Proper Speaker Placement

  • Avoid obstructions around the speakers.

  • Set the volume to a moderate level.

  • Close doors and windows.

  • Keep the room as quiet as possible.

2. Configure Parameters


On the Room Correction page, tap the icon to open RoomFit™ Settings and configure the parameters enhance calibration accuracy or match your preference.

During Calibration


1. Preparation

  • ALWAYS remove the protective case from your phone.

  • ALWAYS hold the phone as far away from your body as possible.

  • ALWAYS point the microphone towards the speaker you are currently measuring.

  • ALWAYS place the microphone at ear level (if you sit while listening, use the height of your ears when seated).

2. Microphone Placement

  • Ensure the microphone, the listener's ears, and the speaker's acoustic center are approximately at the same height.

Step-by-Step Guide to Room Correction


  1. Open the WiiM Home app.
     
  2. Navigate to the Devices tab and tap the Device Settings iconfor your WiiM device.
     
  3. Select RoomFit™.
     
  4. Tap Next to start the RoomFit™ process.
     
  5. Tap Play Sound to perform an audio check.
     
  6. After audio check, select a RoomFit™ type: Stereo Room Correction or Individual Channel Room Correction.
     
    If Subwoofer Calibration is enabled, RoomFit™ will only perform Stereo Room Correction.

     
  7. Tap Start Tuning to begin the acoustic measurement, then evaluate the results.
     
  8. When the Final Assessment page appears, tap Sounds Great to continue. Alternatively, if you are not satisfied with the results, tap Adjust Again to run Room Correction again.
     
  9. Tap Save Profile to save the RoomFit™ results.
     
  10. Tap Done to finish the RoomFit™ process.


Once the RoomFit™ process is completed, the saved profile will be automatically applied to all input sources, so you do not need to perform it separately for each one.
