Pro upgrades

The REW Pro Upgrade adds features for professional users. The first feature is support for capturing from multiple inputs simultaneously, further features will follow. The Pro Upgrade license unlocks multi-input capture and will also unlock all future pro features and is a one-time fee.

Multi-input capture

Multi-input Capture allows REW to capture multiple inputs simultaneously for measurement or for the RTA. Each input can have its own calibration file. Individual SPL metering is available for the first four inputs, level metering is available for up to 32 inputs. Measurements made with multi-input capture will show an rms average of all the captured channel magnitudes with an underlay showing the span of the individual channels and can optionally include individual measurements for each channel and separately averaged sub-groups of any of the inputs.

Multi-input capture would typically be used with a mic array (such as the miniDSP UMIK-X) or a multi-channel interface with multiple analog microphones connected to it. REW captures a contiguous range of input channels. Whilst it is possible to use this feature with multiple USB microphones on Windows when using an ASIO wrapper, this is NOT recommended because:

• REW would only be able to access the input volume setting for the first USB mic and would use that to adjust SPL values for all the mics, so all the USB mics would need to have the same OS volume setting
• USB mics typically provide a stereo pair of inputs, each carrying the same data, so there would be two identical input captures for each mic

The first and last channels to be captured are selected on the Soundcard preferences or the Measure dialog. The example below shows selection using ASIO drivers, a similar selection is offered for Java drivers. On Windows when using the Java drivers select the WASAPI exclusive device entries for multi-channel support (entries starting EXCL: in the device selectors). On macOS or Linux Java drivers offer as many channels as the interface supports.

A license is valid for a single user on any computer they use.

The miniDSP UMIK-X multi-channel microphone system includes an REW Pro Upgrade license.

Before purchasing a license make sure that REW functions as required in its default single channel capture mode.

To enable your license, go to the REW Pro Upgrades menu and select Multi-input capture. Paste in your license code and click Verify license.
