win|RTA is advanced software for sound analysis. This flexible software is optimized for cinema sound, offering features not found in generic sound analysis programs.

There are three versions of win|RTA, one designed to interface with the D2 hardware (win|RTA D2), and two standalone versions (win|RTA Studio and win|RTA Standard).

win|RTA D2 is the software that provides all the multi-microphone test and measurement capabilities of the D2 Acoustical Measurement System. These features are listed in the column to the left and shown with screenshots below.

win|RTA Studio allows you to create your own multi-channel analysis system. It provides the same testing capabilities as those found in win|RTA D2, but with your audio interface and microphones. The interface must have ASIO drivers.

win|RTA Standard is designed to be used with a single microphone or third-party multiplexer. It can perform all tests that do not require software microphone control. It includes 1/1, 1/3, 1/6 and 1/12 octave analysis, pink noise generator, NC and RT60 testing, user-definable function keys, plus audio frequency oscilloscope for cinema projector optical A-chain alignment.

All three versions of win|RTA can add the optional AC-3 test signal encoder.

win|RTA Studio and Standard can be purchased online for Internet download.
