Chuck made me think it was a bit more than 24 bits, now it seems Miller says it's more likely to be 20 bits :) or I just got that way wrong and miller wasn't talking about this at all... so I stick to chuck's answer. cheers 2015-04-23 12:55 GMT-03:00 Alexandre Torres Porres por...@gmail.com:

It's already started 32bit DACs are available from AKM and XMOS, for example. Although I don't know what software/hardware platform you'd use to actually make use of this precision, you can build your own 32-bit sound playback interface with a few boards from HK:

Yep, nice indeed, I guess I learned - in short and in layman's undetailed terms - that audio output is ~24bits (a bit higher, but much higher for smaller numbers). Moreover, digital audio cards won't likely have more than 24 bit precision for many years to come, so it's just way more than enough.

WOW... I just learned something important! So, my whole point here was that I had the idea that DAWs like Ardour support 32-bit considering only values from -1 to 1. But that is just wrong! I just learned you can put a sound file with values in the hundreds / thousands in 32 bit float, load them

According to Wikipedia as of 2007 digital audio converter technology is limited to a SNR of about 124 dB (21-bit) because of real-world limitations in integrated circuit design. Still, this approximately matches the performance of the human auditory system
