I hadn't even thought about SOX 'till your comment in about 10 years. And looking at the page, there hasn't been a new release since 2015. From what I recall, it only worked on wav files back in the day, but now it supports OGG. But a lot has changed in even 5 years - does it even support MP3, as patents expired since then?

I just use SoX for processing audio data, and then pass the result to LAME if I want an MP3. Each format has so many different options for encoding and metadata anyway. It’s not like video, where the sheer amount of data discourages you from working uncompressed. Sure, there hasn’t been a new release since 2015… but would that be necessary? It’s not missing any features I want.

You can check your own with `sox --help`. On Debian mp3 support requires `libsox-fmt-mp3`.

It's not important that it doesn't support mp3. That's not it's purpose - it doesn't need to. The unix philosophy. Feel free to pipeline it on either side with tools that do support MP3.

according to https://github.com/chirlu/sox/commit/af261dcc91071cafd7d83054afb1eb4b2d0083ef https://github.com/chirlu/sox/commit/af261dcc91071cafd7d8305..., sox added support for Ogg Vorbis files in 2001, which is a little more than 5 years ago. since sox didn't exist until 1999 and vorbis didn't exist until 2000, that seems like pretty solid format support to me.
