Should We Worry About Audio We Won't Hear?
In this week’s podcast, Julian is joined by Korey Pereira and Steve DeMott. We discuss sounds we can’t, or won’t, hear. From the merits of high sampling rates to the effect of lossy compression, should we be worrying about stuff no one will hear?

Should We Worry About Audio We Won't Hear?
Talking Points
Should we worry about capturing and preserving sounds we’re never going to hear?
44.1KHz covers 20Hz to 20KHz, why are we recording at 96KHz and higher?
Post-production often has to deal with compromised audio, which is less common in music recording. Because of that is there a case where extreme top end isn’t likely to contain helpful information for a film or television mix?
Has Post opted to favour channel width over HF extension?
Lossy Compressions algorithms discard sounds as a matter of course. Does this affect things?
Bit Depth - Steinberg made 32-bit converters in their UR-C interfaces and Apogee use a 32 bit DAC in the Ensemble. Why aren’t we seeing greater bit depth along with greater sampling frequency?
There is a distribution channel for 96KHz - does that make a difference?
We’ve talked about sounds we can’t hear because they are too high. What about sounds, which are too quiet?
Level and temporal masking in mixes - i.e. sounds which are obscured by other sounds. How significant is that?
