Thanks for that - seems quite a lot of work for a large existing project. I could export a 44.1 project as a 48 WAV file, so converting all in one go to a 48000 file - not sure if there is any lowering of quality of I do that from 44 to 48 though?
If there is any degradation it'll be inaudible. Yes, it is too much work for too little benefit. I honestly can't think of any scenario where it would be worth the effort to convert a project. If you need the final file to be 48 KHz, just convert it while exporting or use an equally-good conversion utility (e.g.
R8Brain) after the fact.
lawp, I'd be very surprised if the SRC algorithm has changed since 8.5. It's a calculation, an algorithm, a formula. Once you've nailed it there isn't much reason to rewrite it, except possibly to implement some optimizations. There is always room for efficiency tweaks, although programmers are usually reluctant to mess with solid, working code just to shave off a microsecond or two. I think we can be confident that SONAR's SRC is just as good today as it was when those tests were done.
