I would like to get a discussion going involving people with experience in mixing the benefits of a higher floating point procession. What is the future of Native since Leopard Mac OS X is going to make 64 bit accessable to the applications. At present I understand that the audio engine in all native systems, Logic Pro 7 / Cubase SX / Protools LE are operating at 32bit floating while Protools HD is operateing at 48bit floating point.

If you are mixing in the box (not running through an SSL console as a summing bus) what are the downsides to native as far as sound quality. Is the TDM plugin archetecture and logorithms superier to the au / rtas / vst counterparts?
Just some questions because I'm wanting to understand where we are and where we are going in terms of strengths and weaknesses in the technology. The above information may not be correct. Please feel free to set me straight. Also worth noting: 64 bit arithmetic is already available and has been for years. I have a G4, it can do 64 bit arithmetic fine. If Logic's engineers wanted to make a 64 bit precision mix-bus they could have long ago.

End user benefits for a 64 bit OS regarding use of Logic will mostly come down to the ability to address more than ca. 4GB of memory. Tiger is a 64 bit capable OS, there are good reasons Logic did not become a 64 bit or in this case multi - distributed 32 and 64 bit apps, mostly because it requires more resources. There is alot of design which goes into a mix bus. Considering you convert a 16 or 24 bit file from int to float and set it through dozens of streams ( aux, bus, outs, plugins ) there's a lot of room to implement things differently along the way. In short, 32bit mix busses don't always give you the same result by the time they get to the output. As far as plugins, you can specify your audio stream on the way in.
If you prefer to use float or int, you can just specify that. On the way back into the mixer it is converted to the native resolution ( in Logic's case 32Float ). PT HD may not offer this ability. If algorithms are superior in one plugin format, then it is a matter of the plugin developer being restricted or not moving the code over properly. Naturally, there is always the decision of how much resolution to use. If the next version of Logic were to handle everything at 64 bit you wouldn't be able to play many of your songs.
But they would sound a little better. So choosing the best balance between performance and resolution is a factor.
NAB, LAS VEGAS—April 6, 2003—Apple® today introduced Final Cut Pro® 4, a major upgrade of Apple’s Emmy award-winning editing software for film, HD, SD and DV. Packed with more than 300 new features, Final Cut Pro 4 introduces RT Extreme, for real-time compositing and effects, powerful new interface customization tools, new high-quality 8- and 10-bit uncompressed formats and for the first time in an editing system costing less than $100,000, full 32-bit floating point per channel video processing. Final Cut Pro 4 also includes three completely new integrated applications—LiveType for advanced titling, Soundtrack for music creation and Compressor for full featured batch transcoding. The revolutionary RT Extreme is an enhanced software-based, real-time effects architecture that scales smoothly with processor speed to support an increased number of simultaneous real-time video streams and hundreds of real-time effects.
RT Extreme allows software effects to be viewed in real time on an external broadcast monitor when connected via FireWire® or an external breakout box. RT Extreme is codec independent and allows editors to preview their work in real time at maximum resolution for finishing quality preview or at maximum performance for increased simultaneous streams and effects. LiveType, a unique new titling application available only in Final Cut Pro 4, enables users to create dynamic, animated titles quickly and easily. LiveType includes LiveFonts, a new approach to text animation in which every character of a font is a separate animated movie. With over 8GB of media including LiveFonts, 150 pre-configured effects, customizable templates, backgrounds, animated textures and objects, LiveType enables Final Cut Pro 4 users to develop their own customized look, either from scratch or by modifying existing effects. With support for DV, SD and HD formats, LiveType allows users to quickly and easily create sophisticated, professional-quality animated text and graphic effects.
Soundtrack, a breakthrough music creation tool also available only in Final Cut Pro 4, gives editors the power to easily create high-quality, royalty-free music scores for their projects. Soundtrack automatically matches audio loops regardless of tempo and key, providing real-time arranging and mixing. Soundtrack is fully integrated within Final Cut Pro 4, supports Final Cut Pro 4’s new score markers for perfect synchronization, includes a library of thousands of music loops and sound effects and supports AIFF, WAV and ACID files. Compressor, a new batch transcoding tool that comes bundled with both Final Cut Pro 4 and DVD Studio Pro 2, lets users batch and export directly to multiple formats including MPEG-2 for DVD, MPEG-4 for streaming media or any supported QuickTime® format. Compressor includes watermarking, real-time preview and 30 high-quality filters and effects, providing an ideal platform for high volume or repetitive encoding tasks.
Compressor comes with a new world-class MPEG-2 software encoder, which provides professional controls for adjusting bit rate and selecting one- or two-pass VBR encoding. The MPEG-2 software encoder delivers pristine quality video rivaling the speed of hardware and software encoders costing thousands of dollars as standalone products.
With its open architecture, Final Cut Pro 4 fits into virtually any production pipeline and provides incredible developer extensibility through a new XML interchange format and FireWire-based I/O framework. This new standards-based composition and metadata interchange format, combined with a new import/export plug-in API, allows developers to create tools that integrate Final Cut Pro 4 into a wide range of production workflows. In addition, the new FireWire-based I/O Framework allows third-party developers to build FireWire-based I/O devices for fully uncompressed 8- and 10-bit 4:2:2 broadcast video.
advanced trimming and timeline tools such as support for dynamic and asymmetrical trimming, master clips, merged clips and ganged playback controls;. enhanced media management;. full support for Unicode;. enhanced audio editing capabilities such as keyframe thinning, multi-track audio mixing, multi-channel audio output and real-time audio effects; and.
Cinema Tools™, previously sold separately, now included with Final Cut Pro 4 with new support for change lists and ink numbers for filmmakers working with 35mm or 16mm film.
