Dirac Control Service in Xiaomi Devices: A Complete Guide to Sound Improvement Technology

If you own a Xiaomi Mi TV TV, A Redmi smartphone or another audio-quality device from the brand has probably encountered the name Dirac Control Service in the list of applications or system processes, a service that often raises questions about what it does, why it consumes resources, can it be removed, and how it affects sound? Unlike standard equalizers, Dirac is an advanced audio processing technology used in premium audio systems, cars and even home theaters. In Xiaomi devices, it is tailored to the mass consumer, but it doesn’t always work.

In this article, we will take a closer look at what Dirac Control Service is, how it is integrated into Xiaomi’s ecosystem, what devices support it, and whether to interfere with it. You will also learn how to check for it on your gadget, disable it (if possible), and adjust it for optimal sound.

What is Dirac Control Service and why is it needed in Xiaomi?

Dirac Control Service is the system component responsible for the Dirac Audio technology that Xiaomi licenses for its devices. Unlike standard equalizers, Dirac uses spatial sound correction algorithms to adapt it to the acoustic features of the room and the characteristics of the speakers. The technology was originally developed for professional audio systems, but in recent years has become available in consumer electronics.

In Xiaomi devices, Dirac Control Service performs several key functions:

• 🎵 Frequency Adjustment – automatically adjusts the bass, middle and high frequencies to a specific speaker model so that the sound is balanced.
• 🏠 Adaptation to the acoustics of the room - analyzes the reflection of sound from walls and furniture, minimizing distortion.
• 🔊 Improved spatial sound – creates a surround sound effect even on stereo speakers (for example, in Mi TVs). TV Q2 or Redmi Smart TV X).
• 🎧 Optimization for headphones – in smartphones (for example, Xiaomi 13 Pro or POCO F5) Adjusts the sound to a specific headset model.

It's important to understand that Dirac Control Service is not a standalone application, but a system service that runs in the background, it activates automatically when you play audio and interacts with audio drivers, which is why it can't be removed without root rights or special tools.

What Xiaomi devices have Dirac Control Service on?

Dirac Audio technology is not used in all Xiaomi devices – it is only available in premium or multimedia-oriented models. Below is a table with the main devices where Dirac Control Service meets:

If your device isn't listed, it's likely that Dirac Control Service isn't on it, and you can check this in two ways:

1. Go to Settings. → Annexes → All apps and search for Dirac Control Service in the list.
2. When playing music or video, open Task Manager (on Android – swipe up with a delay) and check if there is a process com.dirac.service.

⚠️ Note: Some devices (e.g. Redmi Note 12) may have a simplified version of Dirac without a separate service, in which case the technology is built into a standard equalizer and does not appear as a separate process.

How Dirac Control Service Works: Technical Details

To understand why Dirac Control Service sometimes consumes resources, you need to understand how it works. Unlike conventional equalizers, which simply amplify or weaken certain frequencies, Dirac uses:

• 📊 Impulse response (IR) — Analyzes how sound reflects off surfaces in the room and corrects delays.
• 🔄 Adaptive filters – dynamically adjusts the sound to changing conditions (for example, if you moved from the sofa to the kitchen).
• 🎛️ Multi-band compression – smooths out volume peaks so that the sound is comfortable at any volume.
• 🔗 Hardware amplifier integration – on some devices (e.g. Xiaomi 13 Ultra) works directly with Qualcomm audio chip WSA8835.

The sound processing process can be divided into three stages:

1. Analysis: A microphone (in TVs or smartphones) or built-in sensors collect data about the acoustics of the room.
2. Correction: Dirac algorithms calculate optimal settings for current conditions.
3. Application: The settings are transmitted to an audio driver that modifies the sound in real time.

Due to the constant analysis and correction, Dirac Control Service can consume up to 5-10 hours% CPU This is normal, but on weak devices (such as budget TVs) it can lead to slowdowns.

Can I disable or remove Dirac Control Service?

Technically, Dirac Control Service can be disabled or removed, but it's not recommended for no good reason. Here's what happens if you try to get rid of the service:

If you still want to disable the service, follow the instructions:

Open the Settings. → Sound. → Additionally.

Find the "Dirac Audio" or "Spatial Sound" option.

Switch the slider to the "off" position.

Restart the device (required!)

-->

On some devices (e.g., Mi) TV P1) Disabling Dirac will activate the standard equalizer, in which case you can manually adjust the sound to suit you, but you will lose adaptive functions.

⚠️ Note: On smartphones Xiaomi with MIUI 14+ Disabling Dirac may cause user equalizer presets to reset.Save your settings in advance!

How to set up Dirac Control Service for better sound?

If you don't want to turn off Dirac Control Service, but you don't like the sound, try setting it up. Depending on the device, there are different options available:

• 📺 On Mi TVs. TV: Go to Settings. → Sound. → Dirac Modes. Select the profile: Movie (enhanced bass), Music (balanced sound) or Voice (dialogue). Activate Adaptive Sound to automatically adjust to the room.
• 📱 On smartphones. Xiaomi/Redmi/POCO: Open the Settings. → Sound. → Sound quality → Dirac Audio. Choose the type of headphones: Intrachannel, Overhead or Speakers. Adjust the environment level (for effect). 3D-sound).

For advanced users, there are hidden settings that can be activated through ADB Or engineering menus, like on Mi TVs. TV Q2 You can manually set correction parameters for a particular room:

adb shell setprop persist.dirac.custom 1


adb shell setprop persist.dirac.room_size medium

Once these commands are applied, Dirac Control Service will use custom settings instead of standard profiles.

💡

If the sound gets worse after setting up, reset Dirac to factory settings: go to Settings → Sound. → Resetting audio settings. This will help eliminate software failures.

Dirac Control Service Problems and Solutions

Despite the benefits, Dirac Control Service sometimes causes problems, and here are the most common ones and ways to fix them:

If the problem is not solved by standard methods, try the following steps:

1. Clear the service cache: Settings → Annexes → Dirac Control Service → Warehouse → Clear the cache.
2. Update your device firmware to the latest version (new updates often fix Dirac bugs).
3. Reset the sound settings to factory (see instructions above).

⚠️ Note: Some Xiaomi TVs (e.g. Mi) TV A2) After resetting the Dirac settings, you may need to recalibrate the microphone. → Sound. → Calibrate Dirac and follow the instructions on the screen.

Dirac Control Service vs Standard Equalizer: Which is Better?

Many users are wondering if Dirac Control Service should be used if the device already has a standard equalizer.

• ✅ Advantages of Dirac: Automatic adaptation to the acoustics of the room, more natural sound without distortion at high volume, the effect of surround sound even on stereo speakers.
• ❌ Disadvantages of Dirac: Consuming additional resources (CPU It doesn't always work correctly with Bluetooth devices, there's less manual tuning than an equalizer.

If you want maximum sound control (for example, for listening to music in a studio capacity), a standard equalizer may be preferable, but if you watch movies, play or listen to music in different rooms, Dirac will provide a more stable and quality sound.

💡

Dirac Control Service is especially useful on small-speaker TVs (e.g. Redmi Smart). TV X 55”), where the standard equalizer cannot compensate for the physical limitations of acoustics.
