As of 2009, the most common acquisition medium for digitally projected
features is 35 mm film scanned and processed at 2K (2048×1080) or 4K
(4096×2160) via digital intermediate. Most digital features to date
have been shot at 1920×1080 HD resolution using cameras such as the
Sony CineAlta, Panavision Genesis, or Thomson ...
If you're on a Mac or UNIX box, you might be able to do something useful with a UNIX-domain socket and dtach - basically you'd have your recording "server" save to the socket in .wav format, and then have dtach connect to the socket and multiplex the output into multiple encoders (cat, lame, flac, etc.).
It would look something like this:
dtach -A fifo-...
First step when reading audio data from a wav file is to parse the header, especially the 'fmt ' chunk, as described for example in the wikipedia page or on this page.
The 'fmt ' chunk will give you informations on :
the audio format (PCM or not ...)
the number of channels
the sample rate
bits per sample
The audio samples themselves are in the ...
Yes and no. The order is: L - R - C - LFE - LR - RR alright, but the LT and RT is for format mastering purposes only (not to be confused with the pre-mastering normally just called mastering in music), and not used in the actual 5.1-track at all. It is, however, used for the stereo-track and other similar applications.
The AC3/DTS/etc. coding comes after ...
You can find an interesting discussion of "Baby Boom" and Split Surround" and other terms relating to 70mm release prints with magnetic sound here:
These formats had 6.0, 4.1, 6.1, and other layouts. There's a chart here:
These 70mm formats from the late 1970s were for ...
Just an idea (which needs further research): do you actually need the silence to be a file or could you just play dynamically created data? If the latter is the case, you could probably find a solution to call a program that creates a silent audio file in realtime and put that in your playlist. That way you would entirely get around the file size issues for ...
Try dB poweramp music converter. That's what i've used for converting audio files. With the right codecs (which are free) you can pretty much convert anything to extension the you wish to use.
As for finding the files you want to extract from ableton, just search around the ableton folder on your hard drive manually. They should be in there.

If you're just taking existing songs (mp3's for example) you could sort of have each "section" of the orchestra segregated by their main frequency bands and just increase/decrease those frequencies. wouldn't be great. Ideally you'd have multitracks of each section. There's a nice resource of multitrack audio at cambridge-mt.com, but not a lot of ...
you can go for things like "Soundfonts" and apply them on "midi" files but there is no other format for getting pre-recorded "audio" instrument tracks separately. I think Midi files could be enough to fit your needs.
if you choose "midi" format there are many many websites, just Google it. some examples:
Hey one thing that I use for such tasks are automator patches! In apples Automator you can Programm (dont worry its simple) simple movements and tasks like pick a file and move it to this place ... Then you can use the compressor (software You find in the Apple store, best Software to encode) to create a droplett (Icon on the desktop, when you put a file on ...
