balrogg losslessly recompresses Vorbis files 8-12% smaller and Opus 3-8% smaller
balrogg is a lossless recompressor for Ogg Vorbis and Opus files that produces archives typically 8-12% smaller than .ogg files and 3-8% smaller than .opus files.
For engineers managing large audio archives, balrogg offers storage savings without quality loss, though its strict verification model limits which files it will accept. The tool refuses any file it cannot reproduce exactly, excluding chained or multichannel Opus files and files with bad checksums or invalid structure.

balrogg achieves typical size reductions of 8-12% for Vorbis and 3-8% for Opus, with higher effort levels yielding slightly better compression at slower speeds.
The tool refuses files it cannot reproduce exactly, including chained Opus, multichannel Opus, and files with bad checksums or missing end-of-stream pages.
Memory usage ranges from approximately 40 MB per file at effort level -4 to 70 MB at -9 for a 5 MB Vorbis file, with a default 2 GiB process memory cap.
