I’m newbie here. Purchased OP-1 in second hand about two weeks ago.
I was surprised that OP-1 has pretty good converter on its size. (24bit 96khz)
But as I use it constantly, I wonder what the use of these high quality converter?
As you guys know OP-1 can import samples only in 44.1/16 format, also the bounced tracks and albums too!
So how do you guys think about these topic?
I think it’s super overspec.
Anyway, happy to know forum like this.
That may just be marketing BS. They may be quoting the maximum sampling rate and depth supported by the codec. It does not mean it is actually used for anything, i.e., the codec may be configured to operate at a lower setting or the extra bits discarded.
Apparently the ensoniq eps classic also has a divergence between converters and sampling rate. 16 bit converters with 13 bit sampling rate. Given that was 1988, it could be explained by technological and cost constraints of the day.
Could a software update possibly allow for 24bit sampling on the op?
Effects and mixing could be running internally at 24bit or higher. (I bet it’s computing 32 bit internally)
Ideally you want your whole DSP chain to be running higher than your final rate/depth; otherwise you’re losing data at every step you have to downsample, or you’re padding everything down to keep headroom, effectively lowering your bit depth.
Limiting to 16bit to the tape might be for memory reasons, vs computational reasons. But then as soon as you’re doing mixing or effects, you benefit from processing them at higher rates/depths.
Audio is ubiquitous enough that it might be just as easy to source a 24/96 converter as a 16/44.1 chip, and minimal extra cost for comparable noise, linearity, etc. So might just be a “why not” sort of choice.
