Out of memory ESP32 - Githubissues

Thanks for your work with the project. I tried compiling this project to PlatformIO platformio.ini file

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
build_flags = ;-DCORE_DEBUG_LEVEL=5
    -Wl,-Map,output.map
    -DUSE_DEBUG_ALLOC=1
board_build.partitions = partitions.csv
lib_deps = https://github.com/pschatzmann/arduino-liblame.git

Tried to compile it but got a build error xtensa-esp32-elf/bin/ld: region dram0_0_seg overflowed by 6200 bytes

It was decided that it was necessary to disable classes WiFi. And the project compiled with no problem

Advanced Memory Usage is available via "PlatformIO Home > Project Inspect"

But an error pops up when encoding in mp3 after the line mp3.begin(info); I have such an error

MP3: Start encode
==> calloc(1,304) -> 1 [available: 146544]
==> calloc(1,85840) -> 1 [available: 60688]
==> calloc(1,2772) -> 1 [available: 57916]
[Error] lame.c : 2740 - calloc(1,38808) -> 0 [available: 57916]

As I understand it, the mp3 lame encoder needs a lot of memory, but esp32 is simply not able to give so much. It's a pity, I hope this will be solved someday. Thanks again for your work.
