Using Room EQ Wizard to create FIR filters for the A8’s DSP

'm very sorry to bother you, but I have a question, I would be happy if you answer it. I bought an umuk1 microphone and did it as you said from the rew software. Or rather, I couldn't do it the same way as you. I have two questions: 1. What should be the speaker distance from umuk 1?
2. I uploaded my own version and when I listened to the sound, there was very little bass and a very unbalanced sound. Is this process correct to use while listening to music? Thank you now, good luck.

 

The microphone should be placed at your listening position (where your ears are when listening). Just point the microphone towards the center between your speakers.

‘Room curve’ is what you can use to boost the bass.

 

This is wonderful stuff and I really appreciate the effort that you put into it.

I've spent the the measuring and tweaking speaker position, and now I have FIR data ready to upload.

I've searched the forums and I'm left with a really dumb question - where is the DSP menu?

I don't have an IPad - I can't find it on my Android phone or on the touch-screen itself.

Thank you!

On the A8 screen, you can find it here:

 

Bah! I see both icons now. For some reason I thought it would be in Settings. It's always in the last place I look.

Now, I've created and "uploaded" a couple of DSP configs. I'd like to clean up and I don't see how to delete a DSP Config.

?

Thank you so very much for your patience!

 

You can delete all but the original one.

 

Got it - thank you so much.

I renamed the first/bad one "*** don't use" and I'll upload on top of it next time.

Part of my problem is, for some reason, the app doesn't rotate on my android phone. It stays in portrait mode so I don't see the small app icons at the bottom of the screen where the DSP button is. I have to go to the A8 itself.

I've been experimenting with "house curves," specifically one described here:



Big fun!

 

On the iPad, you can change orientation by clicking DMP-A8 and then the horizontal/portrait icon.

 

I don't even see the list-on-the-left that you have on my Android phone. Here's what I see:



The funny thing is, _sometimes_ it will be landscape and look exactly like the A8's display. I see no widgets to switch orientation.

I'll have to check my tablet.

 

I think, landscape is tablet only. iPhone is portrait only.

Cast Mode on the iPhone automatically goes to landscape, though, to take advantage of the whole screen.

 

I'll have to pay more attention. I'm 90% sure I've seen landscape on my phone.

When in portrait I don't see the tiny "back... home..." icons that you see on landscape on the right.

And it has been landscape at some points. I'll get the tablet out. I'll be using it for Roon anyway.

Sorry to hijack this REW thread. Feel free to trim these posts if it makes sense.

No problem. The Android tablet app is fairly new compared to the iPad app, so it might be slightly ‘behind’.

Android phones will be horizontal in ‘Cast’, I believe (when you see a copy of the A8 screen on your phone).

 

Awesome tutorial. I ordered a Umik 1.

Cant wait to try measurements and DSP.

 

Спрошу в этой теме, чтобы не создавать новую тему.
При воспроизведении файлов формата DSD функция DSP недоступна и значок DSP пропадает с экрана, так и должно быть? Если нет, то в чем может быть причина этого явления?

 

Only PCM up to 192khz is handled by the DSP.

Maybe a bit off-topic, but for those using their A8 through an Audyssey-enabled AV receiver, this is the best advice ever. I stumbled upon it today, and it has transformed the sound of my speakers so much that I just had to share it here. There might be someone else here who could benefit from it as much as I did. Just watch these two videos and implement it if you have a suitable device. The result is absolutely incredible! Yes, you often hear such superlatives in the context of audio, but this truly is unbelievable!

 

Great guide! Thank you so much for putting this together. I did a measurement last night of my two speakers and generated a file for each of them, then I added a Harmon Kardon House Curve to it that I found in another forum. And it has really tamed my bass down, which is what I was really hoping that it would do.

But I don't think that it is doing anything to DSD/SACDs, the volume difference is quite dramatic. So I am trying to find out where I can lower the DSDs gain by -5db to match the FIR Filters that I have created. But can't seem to find that anywhere.

I read that all incoming signals up to 192K are converted to 48K when using any of the DSP functionality, so does this affect the sound output at all?

Thanks kindly in advance!

 

Correct, DSD files are bypassed. Info in this Eversolo DSP document:

I don’t see a way to lower the gain of DSD files.

If your files are tagged with ReplayGain tags/info, it would probably help. The ReplayGain function can be turned on/off under settings. It should work with ‘local files’ as well, if they are ripped with this information. But I don’t have any knowledge about the process other than the fact that some users ripped their music with ReplayGain tags/info…

…and I believe all DSPs downsample in order to have less data to handle. I’m sure it affects your output somehow but there are many opinions on this. If your ears like the result, I guess that’s what matters…
