It’s a pain in the ass. I built one for a steganography thesis and the psychoacoustic model is really what made it difficult.

The psychoacoustic model took more time on its own to code than the PCM splitting, MDCT, windowing and Huffman coding.

It’s a fun project however painful. There’s a MP3 encoder from the early 90s floating around that you can use as a base if you can fix the legacy code. I can’t remember the name though, sorry.
