SoundID Reference does not currently measure or display phase response information as part of its calibration process. The software focuses primarily on frequency response correction, measuring how your speakers and room interact across different frequencies to create accurate calibration profiles for professional audio work.

What is phase response and why does it matter in audio calibration?

Phase response refers to how different frequencies in an audio signal are delayed as they pass through speakers, rooms, and audio equipment. When frequencies arrive at your ears at slightly different times, this can affect the stereo imaging, depth perception, and overall clarity of your mix.

Phase issues become particularly noticeable when multiple speakers are involved or when sound reflects off room surfaces. You might experience a hollow or thin sound, reduced bass response, or difficulty pinpointing where instruments sit in the stereo field. These problems can lead to mixing decisions that don’t translate well to other playback systems.

In professional studio environments, phase coherence helps ensure that what you hear during mixing accurately represents your audio. When phase relationships are preserved, you can make more confident decisions about stereo placement, depth, and the overall balance of your mix.

How does SoundID Reference measure audio characteristics?

SoundID Reference uses a measurement microphone to analyse the frequency response of your speakers and room acoustics. The software plays test tones through your speakers whilst the microphone captures how these frequencies behave in your specific listening environment.

During the measurement process, SoundID Reference assesses acoustic properties across the frequency spectrum, typically taking at least 20 minutes to gather comprehensive data. The software analyses how your room and speaker placement affect different frequencies, identifying peaks, dips, and resonances that colour your sound.

For headphones, the process is simpler since room acoustics aren’t a factor. SoundID Reference applies pre-made calibration profiles based on extensive testing of over 500 supported headphone models. These profiles correct for the inherent frequency response characteristics of each specific headphone model.

The measurement data focuses on magnitude response rather than phase information, concentrating on how loud different frequencies appear rather than their timing relationships.

What information does SoundID Reference display during calibration?

The SoundID Reference interface displays detailed frequency response curves showing how your speakers perform before and after calibration. You’ll see visual representations of peaks and dips across the frequency spectrum, typically from 20Hz to 20kHz.

The software presents several key visual elements:

  • Original frequency response curve showing your uncalibrated system
  • Target curve representing the desired response
  • Correction curve showing what adjustments will be applied
  • Final calibrated response after correction

You can choose from different target curves including flat response, custom curves, or simulation profiles that mimic other listening environments. The interface also includes translation check features, allowing you to preview how your mix might sound on different playback systems from car stereos to high-end hi-fi equipment.

For multichannel setups, SoundID Reference displays information for each speaker channel individually, helping you understand how each element of your surround sound system contributes to the overall audio analysis.

How do professionals use phase response data in studio environments?

Professional audio engineers typically use dedicated phase measurement tools alongside frequency response correction to optimise their monitoring environments. Phase response data helps with speaker placement, time alignment between multiple drivers, and identifying problematic room reflections.

In mixing situations, engineers often use phase correlation meters and oscilloscopes to monitor phase relationships between stereo channels. This information helps prevent phase cancellation issues that can cause problems when audio is played back in mono or through different speaker configurations.

For surround sound and immersive audio work, phase coherence becomes even more critical. Engineers need to ensure that sound sources maintain proper localisation and that the immersive experience translates consistently across different playback systems.

Many professionals combine frequency response correction tools like SoundID Reference with phase measurement equipment to create comprehensive monitoring solutions. This approach addresses both the tonal balance and the timing aspects of studio monitoring, ensuring that mixing decisions translate accurately to various playback environments.

Advanced voice processing tools, such as those found in AI-driven voice enhancement solutions, often incorporate both frequency and phase considerations to achieve natural-sounding results in professional audio production.

While SoundID Reference doesn’t currently provide phase response measurement, its comprehensive frequency response correction remains an important foundation for professional audio work. Understanding both the capabilities and limitations of your calibration tools helps you make informed decisions about additional equipment that might benefit your specific workflow. At Sonarworks, we continue developing solutions that address the evolving needs of audio professionals across various production environments.
