Overview of Pro-L 2

The software delivers clear, transparent sound with high loudness. It includes eight limiting algorithms, each with unique character and purpose, and adds true peak limiting. Users can see levels in real-time with peak gain reduction labels and new display modes. The software supports up to 32 times linear-phase oversampling and provides precise output and gain reduction metering, including true peak metering.

It offers extensive loudness metering that meets EBU R128, ITU-R BS.1770-4, and ATSC A/85 standards.

Additional features include an adjustable meter scale with K-System support and low CPU usage. The software allows separate channel linking for transient and release stages and offers advanced dithering with three noise-shaping algorithms. It uses GPU-powered graphics acceleration and supports double-click text entry for parameter values. The software adapts to stereo, mono, and surround audio formats and provides adjustable look-ahead, attack, and release settings. An optional compact interface layout is available, and it supports common Pro Tools hardware control surfaces.

Other features include MIDI Learn, undo and redo functions, A/B comparison, smart parameter interpolation, and an extensive help file with interactive hints. The software is available in VST, VST3, Audio Units, AAX Native, and AudioSuite formats in 64-bit and 32-bit versions and RTAS in 32-bit only.
