DSP? Does it really do that much???

I have a av processor and did all the testing in various positions which then took all this information and did something and yes it did change the sound overall to the room.

And then I looked under the hood to find out how my system changed and Ohiosaw that it refined distances between speakers and the volume levels. And then it did adjustments to my curve, and isn’t the curve just a glorified way to adjust the various frequency levels that you’d see on an equalizer? The user friendly version.

I mean the curve really was very comparable to what it was before I did DSP and I guess I could make manual changes to it. The only way you can really adjust things like an equalizer within your home theatre system

And then when I use DSP it all goes through a filter and that’s OK (maybe)for home theatre but for stereo listening it’s not a good thing.

All the other crazy quirky things this DSP supposedly does are so difficult to understand and I’m not sure what it accomplishes. The interfaces are not the greatest to use and then you have lots of signal errors which are annoying.

I just wish I understood whether it’s all that good a thing to do. Maybe if I had 15 speakers it may have value but just front and back and a sub and a centre can be easily adjusted by me.

The problem is working with these DSP interfaces when you want to tweak it. If it’s part of an AV processor god help you.

On roon, which I have, I see all the complicated and convoluted changes you can make and quite frankly I’m not sure it’s worth all that. And then it’s being filtered which clearly is not a good thing to do.

Seems dsp may be a value for a lower cost system that is trying to reach toward improved quality but to a higher quality fairly revealing system if you put a DSP filter on it it won't sound very good and it's very similar to throwing a blanket over your speakers.

@emergingsoul There isn’t a system on earth that couldn't benefit from prudent use of DSP, because there’s no perfect room, and there are no perfect transducers. Not at any price. With that frame of mind, why did you buy the thing in the first place? Did you not look into what would be required to get the best results beforehand?

If you wanted honest, experienced user feedback on DSP, you got it, at least from a couple of us. However, it’s beginning to sound as if all you want to do is play devil’s advocate. I’m out. Have a nice day.

You can lead a horse to water.....

 

Here is a fairly easy thing to try in Roon that can deliver big results and demonstrate the power of DSP done well in a particular application.

Can you listen to Roon with headphones? If so what model? For that model find a convolution filter file for it here AutoEQ Web | Results | Recommended (killdozer.uk), download it in a location accessible to your Roon core/server, and set up Roon DSP to use the file when listening with the headphones. Let us know how it turns out.

 

Don’t be afraid of the word "filter". It’s just a word. Filter done right = good. Filter done wrong =bad.

 

I use 5 of these for 5 different headphone models, all with positive results, to varying degrees from marginal to massive, ie good quality cheaper headphones run off a well matched headphone amp now sound more like quality headphones that would cost you a whole lot more..
