Meine Güte, da habe ich etwas angerichtet ...

Ich fing schon an, an meinem Erinnerungsvermögen zu zweifeln
.
Dazu habe ich nun auch mal ein wenig gegoogelt.
Hier ein interessanter Link zum Thema WAV-Dateiformat:

Aber so richtig spannend wird es auf dieser Seite von soundonsound:

Die dort gestellte Eingangsfrage:
Q. Can I feed a 24-bit signal into a 16-bit device?
I want to record eight tracks at once into my Akai DPS12 multitracker, which has six analogue inputs and a stereo S/PDIF input. All the sources will be analogue, either from mics or DI boxes. As I need to get a portable mixer/preamp box for this project as well, I thought a Soundcraft M-series mixer would be perfect, as it has an S/PDIF output in addition to direct outs and would easily allow me to put down the required number of tracks. However, the S/PDIF output is fixed at 24-bit on the Soundcraft, and the Akai's S/PDIF input is fixed at 16-bit. The digital outputs on the other options I've looked at, such as the Focusrite Octopre, are also fixed at 24-bit, which seems to be the standard these days. So now I'm looking at getting a completely analogue mixer and a separate A-D converter to convert two of the outputs. Can you see another solution?
Und hier die entscheidenden Zeilen eingangs der Antwort (Hervorhebung von mir):
SOS Forum Post - Technical Editor Hugh Robjohns replies: Feeding a 24-bit signal to a 16-bit device will result in the
truncation of the bottom eight bits — the device receiving the signal simply ignores the bottom eight bits. This effectively raises the noise floor by more than 40dB but, more importantly, will increase the amount of distortion considerably, especially for low-level signals. This will tend to make things sound 'hard' and 'grainy', but just how noticeable and/or objectionable this will be depends on the kind of music you're recording and the level of quality you expect.
