What possible use could LAME encoder be for here? Amnesia does not use nor entirely support mp3s.

Judging by your signature, you're querying how to convert MIDI's to mp3s. Lame_enc can be used there, but if you're wanting to convert them for use in Amnesia, instead convert them into Ogg Vorbis (.ogg) files in Audacity instead. If you cannot do that, then record the MIDI by setting Audacity to record from the computer speakers (usually called Stereo Mix), then export/render the project as an .ogg file.

As a player, we are also not required to use LAME Encoder in or with Amnesia. No mp3 encoding is done in Amnesia.
