(from Rational Acoustics) is one of the most trusted dual-domain FFT analysis platforms for live sound engineers. Whether you are tuning a festival PA or calibrating a permanent install, proper installation is the first critical step to reliable measurements.
Intel Core i5 (or equivalent) minimum; Apple Silicon or Intel i7/i9 recommended for high-channel counts. RAM: 4 GB minimum; 8 GB or more recommended.
In the Audio Device tab, ensure your connected interface is listed and checked as "Active". On Windows, prefer drivers over WASAPI for lower latency and better stability. On Mac, it will utilize native CoreAudio . Setting Up a Measurement Engine Go to Config > Measurement Config . smaart live v9 install
