Sonarworks SoundID Reference for Headphones is a software solution designed to calibrate and optimize headphone audio output. It aims to provide a flat, neutral frequency response across a wide range of headphone models, allowing users to hear audio as it was intended to be heard during production. The software works by applying a customized EQ curve to compensate for the inherent frequency response characteristics of specific headphone models. This correction is based on extensive measurements and analysis conducted by Sonarworks on numerous headphone units. The result is a more accurate and consistent listening experience across different headphones, which can be particularly valuable for audio professionals, musicians, and discerning listeners. SoundID Reference for Headphones supports over 400 headphone models and offers both average and personalized calibration profiles.
Pros:
• Significantly improves frequency response accuracy for supported headphones
• Extensive database of headphone models with regular updates
• Intuitive interface with real-time adjustments and A/B comparison
• Supports both standalone and plugin formats for versatile use
Cons:
• Can introduce slight latency, which may be noticeable in some workflows
• Requires consistent use to maintain calibrated sound, which may not suit all listeners
The core functionality of SoundID Reference for Headphones revolves around its calibration profiles. These profiles are created through a meticulous process of measuring multiple units of each supported headphone model. Sonarworks uses specialized equipment to capture the frequency response, phase response, and other acoustic characteristics of each headphone. This data is then analyzed and averaged to create a correction curve that addresses the typical deviations from a flat response for that particular model.
When a user selects their headphone model in the software, the corresponding calibration profile is applied. This profile adjusts the audio signal in real-time, boosting or attenuating specific frequencies to counteract the headphone’s inherent coloration. The result is a flatter, more neutral frequency response that more closely resembles what would be heard on high-end studio monitors in an acoustically treated room.
SoundID Reference has the ability to create personalized calibration profiles. Users can send their specific headphones to Sonarworks for individual measurement and calibration. This process accounts for unit-to-unit variations and wear, resulting in an even more accurate correction profile tailored to the user’s exact pair of headphones. The software offers a range of customization options beyond the basic calibration. Users can adjust the target curve to their preference, modifying the overall tonal balance while maintaining the benefits of the calibration. The “Simulate” feature allows users to emulate the sound of different listening environments or speaker setups, which can be useful for checking how mixes might translate to various playback systems.
SoundID Reference also includes a “Translation Check” feature, which simulates how audio might sound on common consumer devices like smartphones or laptop speakers. This tool can be invaluable for producers and mixers who want to ensure their work translates well across various playback systems. The software’s interface provides real-time visual feedback, displaying the original frequency response of the headphones, the applied correction curve, and the resulting response. This transparency allows users to understand exactly how their audio is being modified and make informed decisions about their listening setup.
For users working in professional audio environments, SoundID Reference offers low-latency modes and the ability to adjust the processing resolution to balance between accuracy and CPU usage. The software can be used as a standalone application for system-wide correction or as a plugin within digital audio workstations for more targeted use during production and mixing.
When compared to similar plugins, SoundID Reference for Headphones stands out for its extensive database of supported headphones and the depth of its calibration profiles. While competitors like Waves NX and Toneboosters Morphit offer headphone correction, they typically focus more on spatial audio simulation or have a more limited selection of supported models. SoundID Reference’s approach to calibration is generally more comprehensive, with its personalized calibration option being a unique offering in the market. The software’s interface is also more detailed and informative than many competitors, providing users with a clearer understanding of the corrections being applied. However, some users may prefer the additional features found in alternatives like dSONIQ Realphones, which includes more extensive room and speaker simulations alongside its headphone correction. SoundID Reference focuses primarily on accurate calibration rather than extensive simulation features.
This plugin is best for:
• Audio professionals seeking consistent and accurate monitoring across different headphones
• Music producers and mixers who need to ensure their work translates well to various playback systems
• Audiophiles looking to optimize their headphone listening experience
• Content creators who require accurate audio representation for video or podcast production
SoundID Reference for Headphones represents a powerful tool for achieving more accurate and consistent audio monitoring through headphones. Its extensive database of calibration profiles, coupled with the option for personalized calibration, makes it a versatile solution for a wide range of users. The software’s ability to significantly improve the frequency response of supported headphones can lead to more informed mixing decisions and a better overall listening experience. While it may introduce some latency and requires consistent use to maintain its benefits, these drawbacks are generally outweighed by the improvements in audio accuracy. For audio professionals and serious enthusiasts, SoundID Reference for Headphones offers a valuable means of enhancing their headphone-based workflows and listening experiences.
