The Neyrinck SoundCode for Dolby Digital 2 is a comprehensive suite of plug-ins designed for Pro Tools, enabling audio professionals to encode, decode, and preview Dolby Digital (AC-3) audio seamlessly within their projects. This integration eliminates the need for dedicated Dolby hardware, streamlining the workflow for surround sound production. A standout feature in Version 2 is the Dolby Digital Preview plug-in. By placing this plug-in on a 5.1 mix bus, users can accurately monitor how their mix will sound on consumer devices such as set-top boxes, streaming media players, DVDs, or Blu-ray systems. This real-time preview includes adjustable AC-3 metadata authoring and decoding features, along with dynamic range control (DRC) metering, providing insight into the processing applied during playback. The suite also offers faster-than-real-time encoding through an AudioSuite plug-in, supporting all AC-3 file formats and allowing for punch in/out re-encoding to save time during revisions. The decoding component operates as a real-time AAX Native plug-in or a non-real-time AudioSuite plug-in, facilitating synchronized playback within Pro Tools and enabling simulation of various consumer listening environments.
