Ultimate Audio Playback / Your questions about the PC -> DAC route / Re: Questions, questions , questions....

This is what I find so exciting. The best sound and measured performance is with oversampling... BUT done right. And this is exactly what QAP gives (and OAP will give) us.
One of the biggest issues with 'old' DACs like mine is that they just didn't have the computing power back then to do oversampling/filtering as well as we can now. But if this is now done in the software, and the inferior oversampling/filtering in the DAC can be defeated, then such DACs are given a new lease of life.
In a way, this is a bit like the original McLaren F1 road car. Put it on a track against a 'modern' supercar, and it will struggle (see Martin Brundle's video from a few years ago). However, replace its brakes with modern ceramic ones... and I know which car I'd take.
Mani.
Thank you for repeating what i was trying to explain on computer asylum from about one year ago  The problem was that until now it lacked a software able to do that seamlessly and in realtime. |

The thing i agree the most is the new taskbar. I absolutely hate it with the explorer folders/library. i cannot open a second instance from there, i have to use the desktop.
I dunno about priorities and such technicalities, but in general the system FEELS (which doesnt mean is) smoother.
They said that they improved the audio stack. If and how i dunno, and let you and the drivers writers to do it. i do have a problem with latency on my dedicated pc and i already took the decision to go back to vista. Probably i'll stick to it until w7 SP1 comes out.
This is from an early adopter of all MS OSes. W7 betas and RCs had lots of problems, and the RTM needed about one month of updates to be stable.

The decoding of the PCM data (which is in the files) is done by means of codecs, say, decoders. Normally we don't choose them, but we can. One may run leaner than the other, one uses the memory different from the other. It is not much different from the Engine#3 settings/possibilities, although the only thing under our control is the choose of codec (and each *will* sound different, which is a promise ... ). But what about the possibility to play multi channel audio in stereo or the other way around *hint hint* BTW, you have opened a can of worms, be careful that they dont bite  |

The remastered early Beatles cd's were originally recorded in mono. From what I read, digitaly, they sound much better in mono than in stereo. That might be one reason. I remember. The mono versions do indeed sound better. |

Hi, I had the same problem with Windows 7 Home Premuim (64bit), and changed to Windows 7 Prof (32bit) and since then everything is running smoothly. Greetings christoffe So it was some 64 bit driver? Mind to explain better? I'm not going back to 32bit with 4gb of ram and some software that uses 64bit calculations. I think that Peter finds 32 bit floating point sufficient for all tasks so far |

have changed to operating in Unattended mode and much better in fact no problems at all in Unattended.
The only problem is that it needs a keyboard (or a WORKING remote) instead of the mouse, and i dont like to listen to music with the keyboard at my side. |

After reading your original post again, now together with your last post, your problem will be something else;
Generally : not enough horse power, plus I guess you will be using XX in Attended mode, which makes things worse.
Of course the "not enough horse power" may look to you as a stupid reason, but it really is so that certain tasks have to be accomplished before other things can continue, and it is already known that some CPUs don't deal well with different threads and priorities. And laptops ? ... well ...
Peter, I too get this error sometimes, with cpu always <30%,so it's definitely not a "not enough horsepower". |
