Time alignment (channel delay alignment)
SoundID Reference for Multichannel delivers accurate adjustments for channel delays to ensure perfect time alignment at the listening spot, with sub-millisecond precision. The time delay calculations are based on phase response measurements, which are taken during the speaker measurement process. Thus this feature is sometimes called phase alignment.
How to enable the time alignment feature?
Time alignment will be applied by default when loading your speaker calibration profile in the DAW plugin. It is located in the Listening Spot section, and can be disabled manually, see below: 'Adjust to listening spot delay'
Does this feature correct the phase response of the speakers?
No, this feature only aligns individual channel delays of the speakers based on phase response measurement to ensure the simultaneous arrival of sound signals from all speakers to your ears. Depending on your system, this often brings significant improvements in terms of sharper sound stage and overall clarity.
Is latency affected by the time alignment feature (Zero Latency)?
The Zero Latency feature in SoundID Reference refers to our core DSP engine running in the zero-latency DSP filter mode. With time alignment enabled for soundstage correction, those delays will be added on top of the full-cycle latency (reported in the Latency overview at the bottom-left corner of the plugin).
Time alignment added delay figures will depend on each individual setup, the exact values will be shown in the Listening Spot section.
What about phase correction?
Yes, we plan to introduce a phase correction feature in SoundID Reference for Multichannel with a free software update for Multichannel license owners in 2023.
