Isn't that the idea of the output tab in winamp?

Hi there,

I have been playing with asio4all for months, and i am able to get it up and running, can hear audible SQ difference. However there are still a few question i would like to make clear?

1. What does the Hardware buffer does, i tried switching it on and off and i can hear difference, with hardware buffer on i can hear the vocal to be more focus. Should i leave it on or off?

2. The volume level too loud or should i said bright, it is not loud but just too bright especially vocals, i can't listen to the volume level i wanted to because the high frequencies are just too loud. I tried adjusting any digital volume on foobar, and it seem to lose SQ after -5dB. I've setup the replay gain at foobar to run at -7.0 to -10dB and the main volume to -5dB, that lowers the volume a little, but will it affects the SQ?

3. I also used the channel mixer dsp on foorbar to redirect the bass from the sattelites to my subwoofer, will that affect bit-perfect?

Thanks.

1. A buffer stores input or output data in memory for a short while. It makes sure that your device won't have any problems using this data. I suggest you keep it on as long as you use your device just for playback.

2. I don't know. If you can tell me what device you are using I might be able to tell you a bit more.

3. Not necessarily. It depends on how this is done. You can however use the channels provided by ASIO4All to avoid this problem.

I have an analog control on my amplifier and connected to a citypulse DA 7.2x external DAC. The DAC is connected to my PC via a USB-S/PDIF converter as a transport. There are only 3 places where i can adjust my volume. Analog control at my amp, main volume at foobar and replay gain. Which would be the best option?

Mixer at ASIO?? i din't see any mixer before? Is there any?

Enoyin,

I also read an article you post on Hydrogen audio about volume controls, it was said the attenuation degrades bit depth, so what you can do is to increase the normal CD bit depth from 16 -24bit and do some digital attenuation to compensate for the loss. How true is that? And what bit depth is ASIO4ALL working at?

I suggest keeping every digital volume control maxed and just using the analog volume control.

You can asign channel in foobar by editing the ASIO4All virtual device. All the channesl have to be available as true device channels though.

Let get this clear first: I did not post anything in the thread at HydroGen Audio. It's just a discussion about these things. I had nothing to do with it.

I have no idea about the how true all of this is. It might work and it might not work. It's just a thread I linked to for all the people who might be interested in this.

ASIO4All is working at the bitdepth of the files you play. Hence bit-perfect. Most likely this will be 16-bits/ 44.1 kHz since this is commonly used on CDs. It can change depending on what files you are playing. If you play 32-bits/ 192 kHz it will work with that. It will just play everything like it is without changing it. ( assuming the device you are using is capable of of the sample rates etc)

Sorry about that, what i ment was the link to the forum you posted on this thread.

Thanks for your advice.

I am no audio engineer, can't tell anything theoretically, so i guess i'll just try it out and see if there is any difference.

Cheers.

I think that is the best way no matter what. If you can make it sound good to your ears than that is what you should use.

now you say something about the way windows vista processing the sound differently than xp. im using vista right now with asio4all applied i think successfully through winamp and using my av710 soundcard. what is the difference between vista and xp if you can explain briefly

I will make a part about Vista. I don't know how fast I will be able to make it. Maybe tomorrow or the day after.

In short: When using kernel streaming or asio there will be no problem at all. It's mainly the direct sound etc which really changed.

I made the part about Vista. If you want more explanation on that subject I suggest you go to the link I provided. Since this is not a thread about the audio-architecture of Windows, but about ASIO I would like to stay at least a tiny bit on-topic.

Cheers.

Just thought I would report in that your instructions, which worked perfectly with the Bithead, work equally well with the Micro DAC. Well done!

I took a look at the thread and searched around the forum and could find a solution to this problem. Hopefully, I'm just missing something. Here goes. Currently, my setup is from my laptop -> silverstone eb-01 -> gilmore lite. I have everything set up the way it was detailed in the beginning of this post, but the volume that comes out is very quiet. I'm not used to turning my amp up so high to hear. Is there a fix?

Q: My volume is not what it’s supposed to be. How can I fix this?
A: Windows is changing the volume sometimes, just for fun. You can change this in the menu “Sounds and audio devices” in your configuration window.
This is one suggestion taken from the FAQ.

I experienced the same thing when hooking up my USB-DAC. Restarting your computer might do the job as well.

If these things do not work post here again and I will try to think about something else.

I got no sound out of the eb01 until I disabled the onboard sound and a reboot. Since then it's worked fine.
