Hi ! Is there a way to calculate the spectrum?

For the MP3 codec, look at the libmad docs. There is a callback where you can look at the frequency buckets before it converts them to the time domain with 0 add'l cost. OTW you need to make your own band-pass filters to get energies at different frequencies and use it as a part of the output chain.

Hi, I'm trying to get ESP8266Audio's Midi LittleFS example to run on my D1 Mini, but I'm running into an error after I've uploaded the data
"Panic lfs.c:5121 lfs_file_read: Assertion 'lfs_mlist_isopen(lfs->mlist, (struct lfs_mlist*)file)' failed." Any ideas?
