But I also had problems with aliasing frequencies when playing back the high samplerate material at 48 KHZ. Anyone aware of this problem. It was on a
protools HD system.
For the future I will always record with high samplerates when I already know that I want to pitch the material down. Shure the best thing for these pitch Efx would be a stereo nagra, but at the moment I can not aford one.
But still my mastersession is 16 Bit 48 Khz.
The "aliasing" you heard might well have ben a high frequency noise in the recording that you didn't notice 'til it was shifted down. Happens all the time, shift some foley down & you realize that there's a 17k or so tone from the video monitor. Just notch it out with MDW or some other very narrow EQ.
Most of the FX & mixing work I do is at 48/24, but we do record things at 192/24 whenever possible, you never know what might be useful downshifted.
Now if I can just get my Foley guys to make use of the headroom at 24 bit & not clip everything all to hell...This is not a waveform I enjoy listening to:
