REW 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. Individual SPL metering is available for the first four 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. Each input can have its own calibration file. RTA measurements with multi-input capture show an rms average of the individual channel magnitudes.

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:

Multi-input Capture Measurement result

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. Note that Java drivers on Windows are limited to two channels, 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.

The REW Pro Upgrade that unlocks multi-input capture is $100.
Multi-input capture requires REW V5.20 or later.
The license code is delivered by email to the address
registered with PayPal, usually within 24h of purchase. The
email will come from proupgrades@roomeqwizard.com,
please add this address to your safe senders list to prevent
the email being diverted to your junk folder.

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

This upgrade is not required to access multi-channel outputs, to access multiple output channels on Windows use ASIO drivers or an ASIO wrapper like FlexASIO or ASIO4All. On MacOS or Linux multi-channel outputs can be accessed with the Java drivers.

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.
