How Can I reduce the size of AudioTools library?

[hash6iron]

Hi @pschatzmann

I need to reduce the AudioTools library size, because my Flash is at 85%. I don't know if would be possible to remove or disable functions not used or similars. My board is a AudioKit A1S with ES8388 v2. I'm using MP3 and WAV codec, equalizer, metadata filter and basic functions to use the resources of board. I'd like to use then a forked library to adapt AudioTools to my project reducing it.

Any idea?

Thanks in advance.

That's hard to believe: you have 4MB flash available!

What partition scheme did you select ?

With Rainmaker 4MB No OTA you get all flash available for your sketch, which should get you down to 30 %
The other way to reduce the program size would be to remove some of your used functionality: mp3 (or Wifi) make a big difference ...

ps
If you are not using WiFi, you can comment out the following in AudioToolsConfig.h in the ESP32 section

//# define USE_URL_ARDUINO
//# define USE_AUDIO_SERVER

This will avoid the include WiFi.h which should give you an additional 618076 bytes

You are reason, the problem is partitions scheme but I'm using platformIO then I have to customize them.

try with

board_build.partitions = huge_app.csv

And here is the list of the predefined availalbe partitions , so for my initial example you would use rainmaker_4MB_no_ota.csv
