Convert FSB to MP3

QUICK ANSWER
Is it possible to convert FSB to MP3?
Yes - FSB converts to MP3.

Extract the audio samples from the FSB to WAV using vgmstream, then convert WAV to MP3 using any audio converter (Audacity, ffmpeg, fre:ac). Direct FSB-to-MP3 in one step: 'vgmstream-cli -o out.mp3 input.fsb' (vgmstream can output MP3 directly via its encoding options). Note: if the FSB5 is AES-encrypted, extraction is impossible without the game's key.
