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-channel input support and will also unlock all future pro features and is a one-time fee.
Multi-channel 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-channel 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-channel capture show an rms average of the individual channel magnitudes.
Multi-channel 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. 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-channel capture is $100.
Multi-channel capture requires REW V5.20 or later.
