Introduction
Bass Control license

Features
- Bass Management for Multiple Subwoofers: Dirac Live Bass Control supports multiple subwoofers and optimizes the interaction between the subwoofers and the speakers to deliver coherent and tight bass response. This is especially useful in home theaters and high-end music rooms where multiple subwoofers are used to achieve even bass distribution.
- Customizable filters: users can adjust the correction filters to their own preferences. This gives audio enthusiasts and professionals the freedom to fine-tune the sound to their taste, without having to make technical concessions.
- Real-time measurements and adjustments: Dirac Live’s intuitive interface allows users to monitor their room’s measurements in real-time and make live adjustments. This makes it easier to quickly achieve the desired results.
- Advanced Faselinearity: In addition to correcting frequency responses, Dirac Live also optimizes the phasing of the sound, enabling more detailed, spacious and accurate sound reproduction. This results in a more realistic soundstage and better placement of instruments and voices in the sound field.

Description
Dirac Live Bass Control focuses specifically on improving bass response, which can often be problematic in small to medium-sized listening rooms. Low frequencies tend to resonate and accumulate in certain areas of the room, which can lead to messy, inaccurate bass response. Using a microphone, the software measures the acoustic response of the speakers and the room, analyzes this data and then generates accurate correction filters. These filters are then applied to the audio signal, reducing or eliminating unwanted resonances and standing waves in the low frequencies.
Traditional approaches to solving acoustic problems, such as adding absorbent materials or manually adjusting equalizers, can be limited in effectiveness. Dirac Live Bass Control offers a scientific and precision-based solution that takes into account the complex interactions between speakers, subwoofers and the listening room. It ensures that the audio system delivers a tight and controlled sound, with improved definition and dynamics in the low frequencies.
Technical details
Frequency response correction
- Frequency Range: Up to 20 kHz, with focus on enhanced bass response below 500 Hz.
- Multiple measurement points: Multiple microphone positions can be used to obtain accurate measurements from different angles of the listening room, providing better spatial correction.
Bass Management
- Multi-subwoofer support: Dirac Live Bass Control can manage multiple subwoofers in a single system and optimize their output for even bass throughout the listening room. The software ensures that phase, time alignment and frequency response between subwoofers and main loudspeakers are optimally matched.
- Individual subwoofer calibration: Each subwoofer can be calibrated individually to solve unwanted resonances and modal problems.
Signal processing
- Digital Signal Processing (DSP): Dirac Live uses highly accurate DSP algorithms to correct acoustic problems. It applies both amplitude and phase corrections to optimize the frequency response and timing of the sound.
- Phase linearity correction: In addition to amplitude (frequency response) correction, Dirac also corrects the phase of the audio, resulting in coherent sound reproduction without phase shifts, which is especially important for tight bass reproduction.
Calibration process
- Automatic calibration: The system provides an automated calibration process that allows users to measure their room using a measurement microphone (compatible with standard USB microphones). This process automatically generates filters tailored to the specific acoustic characteristics of the room.
- Manual adjustments: Users can also make manual adjustments to the suggested corrections for personal preferences, with control over curve shape and adjustments in different frequency ranges.
- Real-time visualization: During the calibration process, users can visualize in real-time the frequency response of their room, as well as the phase correction and impact of the applied filters.
Latency and performance
- Low latency: The system introduces minimal delay (latency), making it ideal for applications where synchronization of picture and sound is essential, such as home theaters and gaming environments.
- Processing requirements: Dirac Live Bass Control requires a compatible processor (DSP or computer-based processing) to execute its filters. Many modern AV receivers and processors are already equipped with the computing power required to execute these complex algorithms.
Supported hardware and software
- Compatibility: Dirac Live Bass Control is compatible with many high-end AV receivers, amplifiers and standalone DSP systems that support Dirac Live. It is also available for use on PCs and Mac systems with compatible audio cards.
- Supported platforms: Windows, macOS and AV processors compatible with Dirac.
Interface and ease of use
- User Interface: Intuitive graphical user interface (GUI) with customizable filters and calibration curves. The interface makes it easy to make measurements, apply filters and visually assess results.
- Cloud integration: Ability to store and sync settings and calibrations with the cloud, which is useful for users managing multiple rooms or systems.
Software Integration
- Compatible with Dirac Live Full Version: For those who want more control, the Bass Control module is fully integrated with the full version of Dirac Live, which offers additional high-frequency correction capabilities and advanced adjustments across the entire frequency range.
Systems and specifications
- Software requirements: At least Windows 10 or macOS 10.13 or higher. The software works optimally on systems with 8 GB of RAM or more.
- Licensing: Dirac Live Bass Control is usually bundled with AV receivers or sold as a separate license for use on PCs and Macs.
