Some time ago I've readed tons of stuff about samplerates.. so I switched from 96 to 44,
but now I've made an experiment and have some questions about it.
Here it goes,
the setup is:
- Nuendo 3
- TestGenerator plugin from Tools
- IXL Analyser
Pic 1: 44KHz - 1000Hz sin wave - VComp is off
Pic 2: 44KHz - 1000Hz sin wave - VComp is on, no knobs
Pic 3: 96KHz - 1000Hz sin wave - VComp is on, no knobs
touched well, seems pretty same here, here we go with 16000Hz sin
Pic 4: 44KHz - VComp is on, no knobs touched
some additional harmonic apeared at ~12KHz..
Pic 5: 96KHz - VComp is on, no knobs touched
nothing here lower 16KHz at 96KHz.
turn VComp at Input = +13, Output +3, Lim = on, Compression ratio = 1:6
Pic 6: 44KHz
Pic 7: 96KHz
Here we can see additional freqs plus some
noise at 44KHz, and clean picture at 96KHz..
that's it. Same pictures I've got
- waves VComp
- waves C1
- LiquidMix compressors (some of them add
much more strange harmonics at 44KHz)
- Izotope Trash compressor
at 44 and
96 works same:
- Nuendo's Dynamics compressor
- Oxford Dynamics
that's all plugins i've got.
So can somebody explain this difference?
