Package audio is the acoustic I/O seam for murmur.

Package dsp holds the sample-level building blocks: transforms, filters, resampling, windows and detection.

Package fec provides the error-detection and error-correction primitives used inside a burst.

Package link is murmur's one-way path: no handshake, no acknowledgement, no encryption.

Package mac owns the bytes of a burst: the frame header, its encoding, and the integrity check that decides whether a burst is used or discarded.

Package modulation turns frame bytes into a waveform, and a waveform back into frame bytes.

Package sim models the acoustic channel for tests and for `murmur bench`.

Package transfer gives the acoustic link file semantics.
