I made an equalizer using eq10q filters. Now I want to use my equalizer for music equalization and make my own music player. So I have some doubts:
If I want to equalize MP3 files, do I have to decode the MP3 file to PCM audio, apply my filters and then play the audio?
What library or codec do you recommend me to this task?
Is possible to apply filters to an MP3 file without convert the data to PCM?
