Additional misc notes

for all libraries, add -mlongcalls
libmad, libflac (no esp's version), libvorbis (tremor - not esp's version), alac work
libfaad does not really support real time, but if you want to try
- -O3 -DFIXED_POINT -DSMALL_STACK
- change ac_link in configure and case ac_files, remove ''
- compiler but in cfft.c and cffti1, must disable optimization using #pragma GCC push_options #pragma GCC optimize ("O0") #pragma GCC pop_options
better use helixacc
set IDF_PATH=/home/esp-idf
set ESPPORT=COM9
