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.

Hey... Try to look at post #163.
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?
Jesper.
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

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!

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?

If you run camilladsp on the mac, if you can install bluepy and other python stuff along with the BLE stuff, i would work.
I would say... sure it's possible Segment Display Tutorial for Arduino, ESP8266 and ESP32 - DIYI0T
It's just fun and a lot of work.
Could you try installing the BLE and python stuff on the MAC?
My python script look's like this now ::

Lykke- sorry for not being able to support this. I have an older version of Camilla and I rely on Henrik to get up to version that supports this. Not forgotten!!!

Cool 🙂
Is it not possible that you compile it yourself on the mac? or is this to complicated?
Did you buy any of them ESP32 yet?
Merry xmas also!
Let's see how it goes TNT...
Right now i'am testing it in reallife test.
I'am unsure if the battery operation will last for very long, eventhrough i let the ESP fall deep asleep when not in use; an option is to make a dedicated switch on the remote, but it's not my original idea!
As it is now, the following thing's are working ::
A) Pretty fast - actually very good responce when turning volume up/down, pause/play and mute.
B) ESP goes to deep sleep after 60min when not used - Working good enough.
C) When pressing a "long" press, remote is sending play/pause + the voltage of the battery. - Also work's as expected
D) Every time the ESP32 is awakened after sleep a counter is triggered and the number is pasted in the homedir. (This can be read along with the battery voltage by sending a ssh remote command, which i do from my phone and see the results) - Works good as i intended 🙂

Too complicated for me. No ESP32 as of yet but I will surely buy one and a decoder.
Did you think more about level/battery indicator?

I'm now on 0.5.0 🙂 thanks to Henriks new Mac install script.
You have to be very clear about this with me: What goes into the ESP32 and what shall go to the server (if anything) 🙂
I see the python script in post #191 - thats should run on my Mac - where?
You: ...BLE and python stuff on the MAC... "BLE stuff"... ehh? 🙂
Is a 24 p/v encoder OK?

Morning; 🙂
1.) If it should sit in/on the remote box where the ESP32 is, it will for sure use a LOT of battery, and also so many gpiopin's that we defently have to use some shiftregister or like to reduce the number of gpiopins used.
2.) If it would sit on the amplifier/pc/mac/raspberry end, we have no issue with battery ofcause, then we must connect the segment displays there. -The segment display use a lot of gpiopins as i wrote so it could also be an issue there, eventhrough i didn't look at this.
Where should it be TNT 😀
Great news camilladsp 5 is running on the Mac now 🙂
My setup is ment to run on a Raspberry Pi with TinyCore Linux / picorePlayer 6.10 or like ::
Well i will eventually (maybee... no promises) write a guide for this!
The Arduino script/sketch are installed on the ESP32 and is running there with usb or battery power. The ESP32 must be programmed through the Arduino IDE, there are lot's of guides around the www. for this. - The lib's needed are written in the "header" of my script!
The Python script are installed on my Raspberry pi, should reside on your'e mac for this setup.
You need to somehow install some BLE/Bluetooth stuff on the Mac so that it can recieve the commands from the ESP32.
I use BlueZ on my Raspberry Pi for this. -Also python libary are needed, i use bluepy for this, but i'am sure there are other way's also?
Mac is unknown country for me sry... but maybee BLE-tools like hcitool & gatttool for testing/setting up BLE are avaliable on the Mac?

OK!
Do you think you can prepare someting that I could load into a ESP32 - I'm sure I cant collect all that and ensemble it 🙁
Oh - is that the attached .ino file?
OK, I need to check for Mac BLE support.
I think that the level display and the battery indicator should be on the control device itself but it could be activated by a button so to draw current only when activated. I did som calculations on battery life and realise it is somewhat of a challenge. Ideally under normal use one would not have to recharge more than every other week. I suppose responsiveness is what must suffer somehow so that a lot of sleep can be allowed. But maybe is not such a important feature... as long as one can charge while using it... maybe I'll pick a 1500mAh one.
Need to check all the software aspect before I order all this.. thanks for the answers!!

I think i will buy this one FireBeetle ESP32 IoT Microcontroller (Supports Wi-Fi & Bluetooth with 15 ESP32 Projects) - DFRobot
It's possible to order in here in DK, price is actually lower than what i paid for the Adafruit one. The FireBeetle are much lower powerhungry.
Can you perhaps open a terminal on the Mac and see if hcitool & gatttool exist allready??
Good sunday there.
