• Dolby Program Optimizer VM600

    • Created for broadcast operations that are shifting to virtual workspaces, the Dolby VM600 software platform provides a file-based workflow solution for loudness correction, audio conversion, and upmixing.

    • Screen capture: The Dolby VM600 can process up to 16 work orders simultaneously.

      • Workflow Automation

        The software counterpart of the versatile Dolby® DP600 and DP600-C hardware platforms, the Dolby Program Optimizer VM600 can simplify and automate your broadcast workflows. We designed it specifically for cable, satellite, IPTV, terrestrial TV, OTT, radio, and postproduction facilities.

        Loudness Law Compliance

        Responding to consumer concerns, many countries regulate broadcast loudness. The Dolby VM600 offers you a simple, effective, and scalable way to ensure compliance with CALM and with EBU loudness laws.

        Comprehensive Processing Capabilities

        The Dolby VM600 can encode, decode, convert, or transcode audio between a number of popular file formats alone or within media containers, using your own virtual infrastructure and storage systems. It can encode Dolby Atmos® content, and it also includes a high-quality single-step Dolby Digital to Dolby Digital Plus™ transcoder that preserves the metadata and minimizes tandem coding losses.

    • Features

      • Audio Encoding/Decoding and Transcoding

        Provides faster-than-real-time file-based encoding, decoding, and conversion between most Dolby audio formats (Dolby Digital Plus, Dolby Digital Plus with Dolby Atmos content, Dolby Digital, and Dolby E), and PCM, MPEG-1 LII, AAC, and HE AAC v2, while preserving the audio metadata.

      • Automated Loudness Analysis and Correction

        Delivers a more consistent, reliable, and high-quality experience without the need to manually validate and correct each piece of media. The virtual form factor allows jobs to be processed up to 12 times faster than on the DP600.

      • Patented Dialogue Intelligence Algorithm

        Delivers effective speech-based loudness normalization and automatically sets and/or corrects dialnorm values within media files without the need for decoding and reencoding.

      • Automated File Conversion and Transcoding

        Simplifies conversion of archives to next-generation formats. The high-quality, single-step Dolby Digital to Dolby Digital Plus transcoder preserves the metadata and eliminates transcoding losses.

      • Intelligent Upmixing Capability

        Enhances legacy two-channel content with our unique stereo-to-5.1 algorithm that creates a wider, natural-sounding sweet spot and ensures elimination of artifacts in any subsequent downmixing.

      • Hot Folder Mode

        Simplifies integration into existing workflows. Select a specific profile, and all media files moved to the hot folder will be automatically processed to that profile and delivered to a folder you define.

      • Audio Description

        Enables encoding of Dolby Digital Plus content with a supplemental descriptive commentary track and ducking metadata for visually impaired viewers.

      • Two Configurations

        The Dolby VM600 is available in two versions to fit your workflow requirements: one that allows eight simultaneous work orders and another that allows 16.
