Azimuth [ADV]

Overview

The Azimuth module provides control over left and right channel gain and delay. Azimuth adjustment can help repair stereo imbalances and phase issues that can occur as a result of issues introduced by speed inconsistencies.

Controls

Azimuth module interface

  • LEVEL (dB): Adjusts the gain of the left and right audio channels
  • ADAPTIVE MATCHING: Enables automatic gain adjustment of the right channel in order to match the level of the left channel over time.
  • DELAY (samples/ms): Allows for manual adjustment over the delay in samples or milliseconds of the left and right audio channels. For very accurate azimuth correction, RX uses oversampling to achieve sub-sample delays.
  • ADAPTIVE AZIMUTH ALIGNMENT: Enables automatic time-variable adjustment of the right channel’s sample delay in order to align the waveform with the left channel.
  • SUGGEST: Analyzes the selection and determines the appropriate amounts of fixed gain and delay to apply in order to align the two channels.

Suggest & Adaptive modes are only available on stereo files

The Suggest function and Adaptive Matching modes are meant to function on stereo files, these controls will be disabled in the Azimuth module interface when a mono file is selected.

More Information

Use Azimuth to fix gain and delay alignment issues

Azimuth adjustment can be useful to repair inconsistent gain or delay alignment between left and right channels.
For example, gain and delay alignment inconsistencies can be introduced by improper tape head alignment.


Use Azimuth before processing with Center Extract

Azimuth adjustment is recommended to be applied before Center Extract processing to achieve the best results.
