Module codec 

Chunk-level codecs: compression, then authenticated encryption.

Order matters and is fixed: compress, then encrypt. Encrypted output is incompressible, so the reverse order would make the compressor useless.

Modules

compress

Per-chunk compression with an adaptive “is this worth it?” gate.

crypto

End-to-end payload encryption, layered inside the transport’s own TLS.

pcm

Lossless codec for uncompressed PCM audio.
