Is it possible to convert .mp3 audio to .str format?
Converting MP3 Audio Files directly to PlayStation Video Streams (.mp3 to .str conversion) is possible, even though your options are quite limited. This conversion relates to users attempting to encode MP3 audio to STR video.
Try using a media editing software or (online) conversion tool, such as SUPER, which should allow users to import MP3 audio and export it in STR format.
