SuperPlayer - The DSP_Engine (CamillaDSP) samplerate switching & ESP32 remote control

[pi r]

Depending on what 3.3 V regulator chip they use on the ESP-board you use, there is a chance that the voltage regulator itself sucks most of the juice from your battery.

You need a regulator with a very low idle current consumption. The one on the WEMOSs ESP32, draws 40 µA. There are better ones, and maybe you have a good one on your ESP-board.

It's because $samplerate$ is the part of the filename.

Example ::
The /home/tc/camilladsp/filters/$samplerate$l_prefir.bin will be like this in your'e path.
/home/tc/camilladsp/filters/44100l_prefir.bin, because $samplerate$ is set by the plugin (in this example 44100).

Btw: I see no attachment's in your'e post?

Hi Jesper,


My apologies for my mistake. This time you should have the attachments.


I saw the post 163, but as mentioned I do not have any *.bin file.


Cheers,
Francesco

Ahhh... I see now

The config files look right!

You could do the EQ directly in Camilladsp config file i think, BUT ::

If you do what i do, THEN :
You need to create a .bin filter after you do the EQ in REW.

The .bin filter can be created in e.g the RePhase program. rePhase - Official Site - Free FIR filtering tool

This is not so easy to help with, if i do not have the measurements and perhaps youre prefered "house" curve.

Hi Jesper,


now we are on the same page, finally I was able to make clear my issue .


I have followed the tutorial in the video:


Correct your speakers with REW, UMIK-1 and Equalizer APO (Room Correction Tutorial) - YouTube


Attached you can find the average of the measurements and the final result with the filter applied.



What advantage is giving the rePhase procedure vs EQ in REW?


Do you know some tutorial which explain how to do steps by steps? Something for a "dummy" like me ! I have found the guide attached (pdf), but it is not so clear to me.


Thank you so much!!!!

Hey...

I had a look at the measurements...
Could you post the "raw" measurements you took (Left + Right)

I can then make a .bin file for you if you wish?

Good day!

Jesper.

Hi Jesper,


I prefer to learn but there is always time and furthermore I cannot absolutely refuse your kind help .


I am leaving for work, in one month, when I will come back at home I will do the measurements properly, in fact so far I am in the learning mode and I did no accurate measurements (I have neither separate L and R).


Thank you so much and all the best.


Speak you soon,
Francesco

Nice... take care out there then!

Hey all...

I'am developing a remote controller for the "SuperPlayer" or whatever used.

This is just a teaser, but i am testing it right now in "real life" for fun

Thing's which are working ::

Batterypowered ESP32 (this is a very good gadget!) Adafruit HUZZAH32 – ESP32 Feather Board ID: 3405 - $19.95 : Adafruit Industries, Unique & fun DIY electronics and kits

BLE (Bluetooth low energy) is sending volume up/down (either lms volume or camilladsp volume), play/pause with single click on encoder & double click toggles mute/unmute.

It seems to be working very stable, with battery... I don't know how well this works for long time testing yet. - The ESP goes into "deep sleep" mode after 1hour of operation. - Still lot's of things to work with ... But sure it's fun to do!

Jesper.

Well done Jesper!!

This would be so perfect with my headless Mac Mini running Camilla!

Will it work also on Mac?

Is it hard to connect a 2 digit display to output the current attenuation?
