Release Overview
 

The 9.3 update focuses on the signal generator and enhancing Smaarts electronic reference capabilities. You will find a new signal generator GUI, with several enhancements to its options - including the ability to play multi-channel files, adjust the fade-in length, and new Contour options for pink noise. 

The new Smaart Loopback option allows for selected output channels from a device to be assigned to measurement engines as measurement or reference inputs. This essentially makes any audio device used with Smaart capable of internal reference. Find more details on the signal generator and Smaart Loopback below, as well as a full list of feature additions, enhancements, and interface modifications - including new hotkeys(!). 

New Signal Generator Fly-Up Menu

The signal generator settings dialog has been redesigned to fit within the control bar fly-up menu. Just like the View and Timer settings - this allows for manipulation of those settings while simultaneously viewing data, streamlining control.

The signal generator now has four stimulus types available for selection. Pink Noise, Pink Sweep, Sine, and File. Sine and Dual Sine wave functionality have been combined into one stimulus selection type.The Noise stimulus type contains a new Contour selection that is made available when using pseudorandom noise. Pink and Speech Weighted contours are available now, additional selections are planned for future updates. 

File is no longer mono only. Stereo files are supported where the Left and Right sides of a stereo file are assigned to odd and even output selections, respectively. Mono is still default setting, however now it is a sum of the Left and Right channels of a stereo file, and not just the left channel as it was previously. Additionally, the File type selection now automatically opens the file browser when there is not a file previously loaded. 

Smaart Loopback

The new Smaart Loopback feature enables any output selected for use to appear as an input channel for the same device. To enable Smaart loopback, navigate to output config by selecting Config > I-O Config > Output and select the Smaart Loopback checkbox. Once enabled, output channels become available in the channel selection drop-downs for spectrum and transfer function engines. 

Note: the Transfer Function measurement engines referenced to Smaart Loopback are not delay-compensated and the resultant delay times will be the propagation delay of the measurement, with additional delay between any audio buffers in use and the Smaart Loopback channel.
