Octatrack AD/DA converters blind test

I always thought OT grabbed my sounds with ice-cold hand.

Well, it doesn’t touch the sound (when careful configured / not with the default filter settings) and that’s what I expect from a sampler.

OT AB test : comparison between source / capture

There are two files, you only need to listen to one, note the name (after AD test in title) and decide if The OT capture is before or after the source file Maybe the two files are presented in the same order, maybe they’re not, it doesn’t matter, just pick one I just wanted to rule out any selection/ordering bias assumptions - just listen and decide What’s the OT capture, you know the device famous for flattening/colouring/spoiling everything at the MIxer Inputs so an answer is oranges …

Contrary DT and DN have nice thru sound

At least the DT “colorize” the sound and you cannot turn off this colorization:

Anyone else feels a natural bump in the high frequencies from the Digitakt?

tl;dr: Yup, the DT playback isn’t flat. But it is only a very subtle (≤1db) bump at 5kHz, and a more pronounced roll off above 12.5kHz. I did some white noise spectrum analysis: I generated a 30s white noise file. Here’s a spectrum analysis of it: [orig spectrum] Then just to calibrate my set up, I played that out my audio interface and recorded it back in: [loop spectrum] These are flat well within a db, so we can assume the set up is good. Now I transferred the same white noise file t…
