Initial impressions: WASAPI is MUCH better than ASIO for Hiface

Thread Starter 
I installed both WASAPI and ASIO for my hiface and I believe that the WASAPI implementation is dramatically better.

I get crackles and pops with the ASIO output via BNC to my Little Dot. The crackles and pops appear to be associated with CPU and hard drive utilization on my quad-core, intel SSD top-end system.

With WASAPI, I get perfect playback.

Anyone else experience the same?

Have you try to increase the buffer in ASIO ? Its on ASIO4all ?

WASAPI is the way to go if you have Vista or 7. I really don't see a reason to choose ASIO over it, at least as far as basic listening is concerned anyway.

I did experience the same that's the reason I started using WASAPI with absolutely no clicks.

I went to WASAPI when I made the swap to Win7, and I've never looked back. Great sound, no interruptions.

Forgive me if I am wrong as I am new to this produce, shoudl the ASIO and WASAPI driver both supply bitperfect audio and if so why do you hear any difference at all?

I don't think he said anything about the audio quality being worse. He said wasapi works better and asio gives him pops because of technical issues.

If you are talking to me,
I didn't say anything sounded better or worse, i was asking a question as I have heard others suggest the same thing about one bitperfect output compared to others. I guess when my unit gets here I can do my own tests

The audio "quality" is the same for me. However, WASAPI does not produce sharp pops and crackles like the ASIO plug in did. It appears to have to do with CPU usage.

Good to know. Is this an issue with the Hiface itself or this happens on certain system only?

I don't have any issues with the Hiface with ASIO4ALL on w7 x64. There are no pops or crackles during playback and the output quality sounds perfect. I've tried running prime95 with all 8 threads going during playback without any issues. I've also tried copying large (6GB) files to/from my array to my drive without any issues. I'm running an i7 920 on an EVGA classified if it makes a difference.

As for reasons to choose ASIO over WASAPI: I'm not sure about others, but I have a lot of 24/96 tracks in my library and like to keep playback bit-perfect regardless of the bit depth and sample rate. As far as I can tell, ASIO is the only way to accomplish this in foobar2000.

For some reason, sometimes ASIO4All seems to have this problem. I've experienced it aswell, from my onboard HP out / optical out.

WASAPI is really the way to go on Win7 anyway... Why use a silly third party product with technical issues instead of a built in Windows protocol that does the same thing?

Is there a player that can automatically vary the bit depth with WASAPI? As far as any documentation that I can find states, Foobar2000 appears to upsample when playing 16-bit audio when set to 24-bit in the output tab. If that's truly the case, it's not possible to allow seamless playback with a library containing tracks of 16-bit and 24-bit depths without manually adjusting the output settings. I'd love to use WASAPI if there's some way to bypass that limitation.

WASAPI is less fiddly to set up than ASIO.

 

Haven't done A-B comparisons but so far, most of my audio is Redbook so no hassles with having to change Bit rates with WASAPI.

More than likely, it's padding 16int to 24int w/ zeros in the 8 bottom bits...still very much bit-perfect.
