ryanfrancesconi/spfk-lame

Pre-built xcframeworks for [LAME](https://lame.sourceforge.io) and [mpg123](https://www.mpg123.de), packaged as a Swift package for macOS.

Libraries

| Library | Purpose | |---------|---------| | lame | MP3 encoding (CBR/VBR) | | mpg123 | MP3 decoding |

Usage

Used by spfk-audio-conversion as a dependency of the SPFKAudioConverterC target, which wraps LAME and mpg123 in an ObjC interface (LameConverter) for MP3 encoding and decoding. This replaces the previous SoX-based MP3 pipeline, enabling true concurrent batch conversion without actor serialization.
