What is Gain Tracking and How Does it Work?

Gain tracking is a feature in Smaart that allows it to adapt to changes in the gain setting of specific interfaces. This only works when gain is controlled from within Smaart’s “Input Meters” window, accessible by the [Shift] + [E] hotkey.

Currently, these are the only available devices that support gain tracking:

  • Smaart IO (Smaart v8 or later. These devices are discontinued)
  • Roland Octa-capture (Smaart v8 or later)
  • Audient EVO 4, 8, & 16 (v9.1 or later. Audient Evo SP8 is not supported)

To use gain tracking with an Evo device, the Evo app must already be launched before opening Smaart.

Once an input on one of these devices is calibrated for SPL measurement, Gain Tracking can be toggled on/off via a checkbox in the I-O Config menu. Once turned on, Smaart will adjust SPL calibration offset based on changes made using the gain control via Smaart's input meters (accessed via View > Input Meters). The accuracy of these adjustments may vary from device to device, in a typical range within a maximum error of about +/- 1 dB from 0-50 when calibrated at a gain setting of 25 dB.
