digital reverb or delay

[Lexman]

It will be interestind to hear it.

Apologies for the poor images, the camera on hand does not focus closeup and I had to hold a magnifier glass in front to barely snap something.

SMD carriers are ready and devices soldered and tested OK.

Will now build mainboard.

Nice work!

For those of you who have an Audigy card and wish to mess with reverb processing in your computer, the kxproject drivers offer several reverb plugins.

Yes, there is where DSP shines. In this case (don't know details of Audigy card) probably with a mix of on board processing as well as host (PC CPU) processing.

The dsp on the sound card does 100% of the sound processing, and the cpu just runs the user interface for making changes. The user interface can even be closed and the card will continue to run it's code. There is no load sharing required, this is how I can run a six channel active xover with time delays and parametric eq and still make 3d cad solid models with the music playing. Someday when I can afford it I will make a home theatre from this pc.

[ingrast]

Some years back I thought the emerging paradigm should be the PC based audio machine.

Now I am somewhat backtracking from that idea, I do not see a solid trend in this direction. May be PC's are not solid and reliable enough - not even too practical - except of course for more or less techno geeks as we ourselves in a way are.

That is, the PC does not look much as an appliance but perhaps for regularly identified jobs like Internet / e-mail.

May be I am wrong, but I feel the PC - capable as it should be for the job - will not storm neither the home theater segment nor the professional stage audio management. I mean, not that it is not used, but that it is not mainstream.

Ingrast, I agree completely with you that the pc is not suitable for mainstream audio. We techno geeks can have variable degrees of success and satisfaction from specialized applications of the pc by being careful, but it is still an experimental system, responding to the hand of it's builder. Perhaps the pc can be thought of as an emulator, which may function well but is constrained to stay in the laboratory. The knowledge gained by using the audio pc is valuable and achieved at minimal cost (important factor for hobbyists with growing families) but to set it free of the lab it must be implemented by more portable and robust means. So keep up your good work!

After some weeks pulling time to work on the project, the basic module is mostly assembled except for the output current to voltage converter.

Power has not been applied yet, so the magic smoke allways packed inside each electronic component has not been released

Apologies for the phono quality, will try to upgrade to a better camera soon.

[ingrast]

Here is a closeup taken through a magnifying glass held in front of the camera.

Will devote next weeks to testing and debugging, and will post results.
