Dirac Live Room Correction Suite ED: A Review
Dirac Live Room Correction Suite ED is a software package that aims to improve the sound quality of your audio system by correcting the acoustic problems caused by your room. It is based on Dirac's patented technology that optimizes both the frequency and the time domain of the sound, resulting in a more accurate and natural sound reproduction. In this article, we will review the features, benefits, and limitations of Dirac Live Room Correction Suite ED, and compare it with other room correction solutions on the market.
What is Dirac Live Room Correction Suite ED?
Dirac Live Room Correction Suite ED is a software package that consists of two components: Dirac Live Calibration Tool and Dirac Audio Processor. The Dirac Live Calibration Tool is a software application that runs on your computer and guides you through the measurement and calibration process. You will need a measurement microphone and a sound card to connect it to your computer. The Dirac Audio Processor is a software application that runs in the background and applies the correction filters to the audio signal. You will need a virtual audio cable or a loopback device to route the audio from your source (such as a media player or a streaming service) to the Dirac Audio Processor, and then to your audio system.
The Dirac Live Calibration Tool allows you to measure the acoustic characteristics of your room and speakers using a series of test tones. It then analyzes the measurements and generates correction filters that are tailored to your specific setup. You can adjust the target curve, which defines the desired frequency response of your system, and preview the results before applying them. You can also create multiple filter profiles for different listening positions, preferences, or content types.
The Dirac Audio Processor applies the correction filters to the audio signal in real time, using a proprietary mixed-phase algorithm that corrects both the magnitude and the phase of the sound. This means that it not only smooths out the frequency response, but also aligns the time arrival of the sound waves from different speakers, resulting in a clearer and more focused sound image. The Dirac Audio Processor supports mono, stereo, and multichannel configurations, up to 8 input channels and 16 output channels.
What are the benefits of Dirac Live Room Correction Suite ED?
Dirac Live Room Correction Suite ED offers several benefits over other room correction solutions on the market. Some of them are:
- It corrects both the frequency and the time domain of the sound, which is essential for achieving accurate and natural sound reproduction.
- It uses a mixed-phase algorithm that preserves the original phase information of the sound, unlike other solutions that use minimum-phase or linear-phase algorithms that introduce phase distortion or latency.
- It allows you to customize the target curve according to your preference, rather than imposing a predefined curve that may not suit your taste or content.
- It supports multichannel configurations, which are common in home theater systems, and allows you to optimize each speaker individually.
- It works with any audio source, such as a media player, a streaming service, or a game console, as long as you can route the audio to the Dirac Audio Processor.
What are the limitations of Dirac Live Room Correction Suite ED?
Dirac Live Room Correction Suite ED is not without its limitations. Some of them are:
- It requires some technical knowledge and skills to set up and use. You will need to install and configure several software applications, connect a measurement microphone and a sound card to your computer, run multiple measurements in different positions, adjust the target curve and filter profiles, and route the audio signal correctly.
- It may not work well with some audio devices or applications that do not support virtual audio cables or loopback devices. For example, some HDMI devices or applications may not allow you to change the audio output device or may bypass the Dirac Audio Processor.
- It may not be compatible with some operating systems or hardware configurations. For example, some Mac users may experience issues with multichannel setups or virtual audio cables.
- It may not be able to correct all the acoustic problems in your room. For example, it may not be able to deal with excessive reverberation, background noise, or structural resonances.

What are some tips and tricks for using Dirac Live Room Correction Suite ED and Bass Control?
Dirac Live Room Correction Suite ED and Bass Control are powerful and versatile software packages that can improve the sound quality of your audio system by correcting the acoustic problems caused by your room. However, they also require some technical knowledge and skills to set up and use properly. Here are some tips and tricks that can help you get the most out of them:
- Before running the measurement process, make sure your room is as quiet as possible. Turn off any sources of noise, such as fans, air conditioners, or appliances. Close any windows or doors that may let in external noise. Ask anyone else in the room to be silent or leave.
- Before running the measurement process, make sure your speakers and subwoofers are positioned and oriented correctly. Follow the recommendations of your speaker manufacturer or use a speaker placement tool, such as [SpeakerAngle] or [SpeakerBuddy]. Make sure your speakers and subwoofers are level, symmetrical, and equidistant from the listening position.
- Before running the measurement process, make sure your microphone is calibrated and positioned correctly. Use a microphone that has a flat frequency response, such as the UMIK-1 or the MiniDSP EARS. Calibrate your microphone using the calibration file provided by the manufacturer or use a calibration tool, such as [REW] or [Room EQ Wizard]. Position your microphone at ear level and point it towards the ceiling. Use a tripod or a boom stand to hold your microphone steady.
- During the measurement process, move your microphone to different positions in the listening area, as indicated by the software. Try to cover as much of the listening area as possible, but avoid positions that are too close to the walls, corners, floor, or ceiling. Use a tape measure or a laser pointer to ensure consistent distances between measurements.
- After running the measurement process, review the measurement results and check for any errors or anomalies. Look for any spikes or dips in the frequency response that may indicate reflections, resonances, or interference. Look for any phase differences between speakers that may indicate misalignment, polarity inversion, or delay. If you find any errors or anomalies, try to fix them by adjusting your speaker or microphone placement, or by repeating the measurement process.
- After creating the correction filters, adjust the target curve according to your preference. You can use one of the preset curves, such as Flat, Natural, or Custom, or you can create your own curve by dragging and dropping the nodes. You can also use a reference curve from another system or room that you like, such as [Harman Curve] or [BBC Curve]. You can also use a target curve tool, such as [REW] or [Room EQ Wizard], to generate a target curve based on your measurements.
- After creating the correction filters, preview the correction results and compare them with the uncorrected sound. Listen to different types of content, such as music, movies, games, or podcasts. Listen to different genres, styles, moods, and formats of content. Listen to content that you are familiar with and that you like. Listen for any improvements or changes in the sound quality, such as clarity, balance, detail, dynamics, imaging, soundstage, realism, etc.
- After creating the correction filters, export them and load them into Dirac Audio Processor. Make sure you route the audio from your source to Dirac Audio Processor correctly. You can use virtual audio cables or loopback devices to do this. You can also use an external device that supports Dirac Live processing, such as a [miniDSP SHD] or a [NAD T 778].
- If you have subwoofers in your system, you can add Bass Control to optimize their performance. Bass Control allows you to optimize the collaboration between subwoofers and main speakers by adjusting their crossover frequency, phase, and level individually. It also allows you to adjust the overall bass level and target curve according to your preference.
- If you have multiple listening positions in your room, you can create multiple filter profiles for each position. You can also create multiple filter profiles for different preferences or content types. For example, you can create a filter profile for music listening with a flat target curve and another filter profile for movie watching with a bass-boosted target curve.
These are some tips and tricks that can help you set up and use Dirac Live Room Correction Suite ED and Bass Control effectively. If you follow these tips and tricks, you can improve the sound quality of your audio system and enjoy a better listening experience.
