Fiedler Audio Dolby Atmos Composer + Spacelab Ignition + Gravitas MDS Bundle — Free Download
A production bundle pairing Dolby Atmos mixing tools with mastering-grade dynamics processing, approved by Dolby Labs for immersive audio workflows across major platforms.
Purpose and Core Components
This bundle combines three Fiedler Audio products: Dolby Atmos Composer, Spacelab Ignition, and Gravitas MDS. The Dolby Atmos Composer is a Dolby-approved toolset that simplifies immersive audio production by removing manual setup and the need for a DAW with native Atmos support. It includes the Dolby Atmos Beam panning plugin for automating complex movements beyond typical DAW limitations.
Gravitas MDS is a flexible dynamics processor (compressor and expander) optimized for mastering but suitable for individual tracks, groups, buses, or full mixes. It handles various channel formats, from mono and stereo up to multichannel configurations. In plugin mode, it supports up to 64 input channels, with higher channel counts available in specific host environments (e.g., Reaper on Mac as an AU plugin).
Key Capabilities and Features
The Dolby Atmos Composer enables advanced mixing workflows by allowing you to use all your existing DAW features, favorite plugins, and instruments within an Atmos mix. You can record new tracks while mixing for Atmos, a capability not possible with some standard workflows, particularly on certain DAWs. The tool exports as ADM/BWF for direct distribution to platforms like Apple Music, Amazon Music, Tidal, and Netflix.
Gravitas offers a comprehensive set of dynamics features: it can create complex compression and expansion curves, limit gain reduction and increase, apply variable filters for both processing and detection, link parameters across all instances in a session, and adjust channel linking and peak mode. The ‘3DET’ mode, inspired by the AMEK mastering compressor, is included. Its input configuration dialog allows flexible routing for multichannel signals.
Workflow and Integration
The workflow with this bundle is designed for efficiency. Start by setting up the Dolby Atmos Composer in your DAW, which handles the Atmos bed and object routing automatically. Use the Dolby Atmos Beam plugin for panning and automation, even if your DAW lacks immersive audio capabilities. Spacelab Ignition connects directly to the Composer, allowing you to add reverb to your Atmos mix without complex routing.
Gravitas integrates as a master channel module within the Atmos Composer, giving you global dynamics control across all 128 channels of your mix. Alternatively, use it as a standalone plugin on individual tracks or buses in any session. Its parameter linking feature ensures consistency across multiple instances, ideal for complex productions.
Practical Applications and Use Cases
This bundle is suited for music producers, mixing engineers, and post-production professionals who need to deliver Dolby Atmos content without investing in a dedicated Atmos-capable DAW. It is particularly useful for projects targeting streaming platforms that support Atmos, such as Apple Music and Tidal. For mastering engineers, Gravitas provides transparent dynamics shaping for full mixes, while its aggressive compression settings can add punch to drums or other elements.
For sound designers, the integration of Spacelab Ignition allows for rich, immersive reverberation that enhances the spatial depth of Atmos mixes. The ability to record new tracks while mixing is beneficial for live or iterative sessions. Since export is in ADM/BWF, your finished work can be directly distributed to Netflix or other platforms requiring that format.
