Overview

WiiM Sound and WiiM Sound Lite provide the RoomFit™ feature to correct their frequency response in your room.

RoomFit™ measures the frequency response of your speaker at your listening position and corrects it to more closely match your selected target curve. This helps reduce uneven sound caused by room acoustics and speaker placement for a more balanced listening experience.

Notes:
  • RoomFit™ measures the Left and Right channels of WiiM Sound or WiiM Sound Lite together.
  • If your speaker is paired with a WiiM Sub Pro, run RoomFit™ on the speaker and Subwoofer RoomFit™ on the WiiM Sub Pro separately.

Preparations and Instructions

Before RoomFit™ Measurement

  • Avoid obstructions around the speakers.
  • Set the volume to a moderate level.
  • Close doors and windows.
  • Keep the room as quiet as possible.

During RoomFit™ Measurement

  • 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 your WiiM Sound or WiiM Sound Lite.
  • ALWAYS avoid obstructions between the microphone and the speaker.
  • ALWAYS place the microphone at ear level (if you sit while listening, use the height of your ears when seated).
  • Microphone Placement: Ensure the microphone, the listener's ears, and the speaker's acoustic center are approximately at the same height.
  • Use an external microphone when available for more accurate RoomFit™ measurements. For details, see Using an External Microphone for RoomFit™.

Step-by-Step Guide

Steps Details
1. Open WiiM Home.

Open the WiiM Home app on your mobile device.
2. Open RoomFit™.

Go to the Devices tab > Device Settings > RoomFit™.
3. Configure RoomFit™ parameters.

Tap the icon to open RoomFit™ Settings and configure the parameters to match your listening preferences.

For details, see Introducing RoomFit™ Settings and A Practical Guide to RoomFit™ Room Correction for Enhanced Sound Quality.
4. Start RoomFit™ process.

Tap Next to start the RoomFit™ process.

Tip: Follow the prompt to rotate your phone 180°, so the bottom microphone faces the speakers for accurate measurement.
5. Audio check.

Tap Play Sound to perform an audio check.
6. Start tuning.

Tap Start Tuning to begin the acoustic measurement, then review the RoomFit™ result from the curves below:

  • Target: The desired frequency response that RoomFit™ aims to achieve.
  • Raw: The measured frequency response of your speaker at your listening position before RoomFit™.
  • Equalization: The frequency-response correction applied by RoomFit™.
  • Predicted: The predicted frequency response after RoomFit™ correction is applied.
7. Evaluate results.

Evaluate the actual RoomFit™ result from the curves below:

  • Target: The desired frequency response that RoomFit™ aims to achieve.
  • Raw: The measured frequency response of your speaker at your listening position before RoomFit™.
  • Actual: The actual frequency response after RoomFit™ correction is applied.

If the Actual curve closely matches the Target curve within the correction range, the RoomFit™ result is effective. Tap Apply Correction to proceed.

If there are large differences, tap Adjust Again to re-run RoomFit™.
8. Save results.

Tap Save Profile to save the RoomFit™ results as a custom profile. Alternatively, tap Skip to save into the Auto profile.
9. Finish.

Tap Done to finish the RoomFit™ process.

Note: 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.
