USBAUDIO: now supports 24-bit and sample frequencies > 65535 Hz

<< < (2/7) > >>

Sigurd Fastenrath:
Just to add:

This is really great stuff! I was able to use with the Driver vom Lars+Wim (older one) and this Hardware:

https://www.amazon.de/gp/product/B01N905VOY/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

on my Lenovo T450s (that I already sold last week):

- headphones
- speakers

and ... YES ...

- microphone

So that I was able to use Voice Type Dictation/Navigation for OS/2 on my pimped up Warp 4.52 nativ on this T450s!

One will see this in my OS/2 Movie, that was estimated to be finished x-mas 2017, but I underestimated the needed Post Production of thís already 45 Minutes Video. But it will arrive....  8)

By the way I supported Lars by sponsoring him via bitwise, and that was something really worth it!

Thanks to Lars and Wim!

64000, 88200,96000,176400,192000,352800,384000 Hz.

Does it work for Playback and Recording in 8, 16 or 32 bits?

How it handles more than 2 audio channels? Is SPDIF digital I/O now possible?

Fahrvenugen:
This sounds fantastic, I can't wait to try it out.

Are the additional sample rates available to any audio adapter, or just USB?

Just wondering - I've got a couple of Warp boxes running audio logging 24x7, I'd love to be able to up the sample rate (they're using onboard audio cards supported via Uniaudio). 

I could of course switch these 2 systems over to using USB audio cards if needed.

Currently they are only available to USBAUDIO because the USBAUDIO installation package updates the MMPM subsystem accordingly.
The problem is an outdated AUDIOIF.DLL and SPI.INI. In principle Uniaudio could also support these higher rates and BitsPerSample (of course only if the HW supports them). But for that it needs an updated AUDIOIF.DLL and SPI.INI.
In order to not interfere with other audio adapters we have decided to build a USBAUDIF.DLL which takes the place of AUDIOIF.DLL so that AUDIOIF.DLL can remain untouched.
