Hey all,
For all the people who like to perform post production DSP on their recordings(for recordings with sample rates of 48 or 44.1), do you upsample to 96k prior to performing any DSP? I had an interesting discussion the other day with the engineer i'm interning with. We talked about DSP and how it can "crunch" the sound of your recording at lower sample rates. He then mentioned that when he masters, he'll upsample the recordings to 96k, perform the necessary DSP, and then resample back down to 44.1. He claimed that when you do this, all of the "processing noise" will be way up in the unaudible spectrum so when you downsample to 44.1, it won't affect the sound of the recording(or as much as it would when performing DSP at lower sample rates). When I asked him about adding the two sample rate conversions into the process(two extra DSP's that some might deem necessary) he reinforced my thoughts that sample rate converters are so much better than they were say 3 years ago and most. So programs like WaveLab, Peak, nuendo, pro tools, and other similar quality programs all have decent sr converters. I had a similar conversation some time ago with a teacher but i never really tested it out that much.
So i was messing around with it last night and I must say I could hear a difference. The difference resulted in a smoother, slightly clearer recording. It especially helped when using heavy EQ on the hi-mids to high frequencies as well as compression(mastering limiter in my case).
Does anybody else do this? I think it's going to be standard procedure for me from now on for any work I do with recordings with sample rates of 48k and 44.1k.
thoughts?
