I have been recording alot of ambient sounds the last weeks and now i got over 100 of 1-2 min clips that im going to edit into useble ambient sounds in 48.1kHz/16bit from 48.1kHz/24. What DAW do sound designers use? And if for example ProTools, what method is used?
Why do you need to reduce the bit depth?
I use PT myself and I am asking myself the question: How could I edit all these files and let the DAW bounce each file separately and have each clip being given its original name (like the date).
It wasn't until PT11 that batch export became feasible, in prior versions there's no option to do batch bounces of tracks or files/regions. It might be even that it's just in PT11 HD and not the normal version (great job, Avid).
Also, i am new to editing ambient sounds, what is usually done? Is there anything special i should keep in mind?
Not really. There are some topics about "mastering" sound effects, if they're for distribution. Generally it's advisable to leave the recordings as they are and only do small fixes, if there's something to fix (e.g. too much mic noise or small EQ adjustments).
Also, you may want to cut out parts that don't belong to the ambience (e.g. if there are car pass-bys or an aeroplane flying over or people talking etc. that doesn't really "belong" to the ambience, although a good recordist would've avoided these already during recording). It's probably advisable to not try to stitch together cut parts by cross-fading (it would be done by the editor using the ambience, if needed. And it doesn't necessarily work).
P.S i also wonder how i can apply dither (and what dither to prefer) to all edited ambient sounds while bouncing them (24 to 16 bits quantization).
Again, not feasible in PT (expect for PT11 perhaps).
Reaper is the easiest to acquire DAW that does everything you need.
