WiiM’s RoomFit™ feature optimizes sound quality by analyzing the acoustic characteristics of your room. Before running the RoomFit™ process, you can customize its settings to match your preferences. This article introduces each RoomFit™ setting in detail.
Target Curve
This setting defines the target frequency response that your WiiM device tries to match after calibration. You can choose from B&K, Harman, and Flat.
Frequency Range
This setting defines the frequency range that RoomFit™ will measure and adjust.
If your speakers have bass enhancement, it's recommended to exclude that frequency range.
Max Gain
This setting adjusts the maximum amount of boost RoomFit™ can apply to any frequency band during calibration.
Adjust the volume level during calibration. Set gain according to the room's acoustic characteristics and personal preference to avoid distortion or unnatural sound.
Min Gain
This parameter sets the maximum amount of cut (reduction) RoomFit™ can apply to any frequency band during calibration.
Max Q
This setting controls how narrow or wide RoomFit™ can make its sound adjustments.
- Lower Q values are suitable for smooth frequency response adjustments.
- Higher Q values are used for precise correction of specific frequency peaks and dips but may cause "ringing."
Non-Boost Mode
This setting ensures that the sum of all correction values does not exceed 0 dB, preventing distortion and clipping caused by excessive boosting.
Built-in Mic Compensation
This setting compensates for the built-in microphone’s deviations, ensuring more accurate RoomFit™ measurements.
This setting is only available on iOS.
External Mic Calibration
This setting lets you import a calibration file for an external microphone to achieve more accurate RoomFit™ measurements. For details, see Using an External Microphone for RoomFit™ Room Correction.
This setting is available only when an external microphone is connected to your mobile device.
Subwoofer Calibration
This setting allows subwoofer calibration during the RoomFit™ process.
This setting is available only when your WiiM device is connected to a subwoofer. Check your subwoofer's crossover frequency and ensure the start of the frequency range for correction is above this crossover to avoid incorrect adjustments for your room's acoustics.
Moving Mic Measurement (Beta)
This setting allows an advanced calibration method that measures sound throughout the listening environment, resulting in more balanced and consistent audio performance. For details, see Introducing RoomFit™ Room Correction with MMM (Beta).
Smoothing
This setting reduces small fluctuations in the frequency response curve, making it easier to interpret and focus on overall trends. It removes unnecessary details caused by noise or measurement artifacts, prevents overcompensation during adjustments, and helps achieve a more natural correction outcome.
- 1/3 Octave Smoothing: Balances detail with overall trends.
- 1/6 Octave Smoothing: Retains more detail while maintaining readability.
- 1/12 Octave Smoothing: Provides highly detailed adjustments for fine-tuning specific areas.
Multiple Measurements (Beta)
This setting allows multiple measurements for enhanced calibration accuracy.
