    Better Surround Panning for 5.1 & 7.1 audio - Open MDA?

    BobbyH5280 Level 3

      I really appreciate the recent improvements to Adobe Audition which added Dolby Digital and Dolby Digital Plus encoding without the need of installing (or buying) extra plug-ins. I think Audition needs some improvements to its sound panning functions for users to get the most out of creating surround sound layouts.


      As far as I can tell the Track Panner dialog box only provides visual feedback to edits applied directly to key frame points on an envelope path in a selected track. If you move anything around in the Track Panner box it will not affect a selected keyframe on an envelope path of a selected track. The user must use a combination of different envelopes (like pan angle, pan radius, etc.) and edit key frames on each envelope separately to create certain "fly by" effects. That approach is not very intuitive and it can be time consuming if you're trying to create certain specific effects. It's tough to manually move around points on an envelope path especially if you're wanting the point to be at a certain numerical setting.

      The user ought to be able to select a key frame and then visually or numerically change the key frame's settings based on changing things in the Track Panner dialog box itself. I could create surround effects a lot faster and more accurately with that approach.

      Currently Audition only allows for mono, stereo and 5.1 layouts in the Track Panner dialog box. What about 7.1 surround? Dolby Digital Plus and Linear PCM both support 7.1 on Blu-ray. DD-Plus is also supported in some other streaming services.

      Finally, "immersive" surround sound is starting to become more popular in both commercial cinemas and home theater. This is a pretty high end thing, but given Adobe's audio/video editing products are being used increasingly on feature film projects it would be great if Adobe built in support for DTS' Open MDA (Multi Dimensional Audio) format. There is some movement on the part of SMPTE to standardize immersive audio on Open MDA. Standardization could mean being able to generate 3D sound mixes that can be output in MDA and played back in a variety of immersive sound systems (DTS:X, Dolby Atmos, Auro, etc.).
