Voxengo SPAN v3.23 VST VST3 AU AAX WiN MAC

SPAN is a free real-time FFT spectrum analyzer plugin that works as VST, VST3, AU, and AAX on Windows and Mac. It gives hobby producers a flexible way to see what’s happening in their mix, with adjustable FFT block size, window overlap, and visual slope. You can display a secondary spectrum like real-time or all-time maximum, smooth the display for easier reading, and analyze stereo, mono, mid-side, or even surround formats like 5.1 and 7.1. Beyond spectrum analysis, SPAN includes output level metering with EBU R128 loudness, K-system metering, true peak and clipping detection, plus a correlation meter. It’s useful for checking frequency balance, monitoring levels, and spotting clipping without spending anything. The interface can be resized, supports Retina and HighDPI screens, and offers color schemes. It runs on Windows XP and later, and Mac OS 10.12 and later, including Apple Silicon. Whether you’re mixing in FL Studio, Ableton, or Logic, SPAN is a handy utility for visual feedback on your audio.
