v3.15.0

Added

  • F16LE / F16BE RTP payload decoding in parse_rtp_samples for radiod's float16 output mode (encodings 6 and 9). Both audio and IQ paths.
  • G.711 µ-law / A-law decoders for encodings 10 and 11 — pure-numpy table-based, no audioop dependency (which was removed in Python 3.13).
  • OpusDecoder class in ka9q.stream for OPUS / OPUS_VOIP payloads (encodings 3 and 7). Lazy-imports opuslib; install via pip install ka9q-python[opus]. Maintains codec state across calls so packet-loss concealment works end-to-end — one instance per stream SSRC.
  • New opus optional dependency in pyproject.toml (opuslib>=3.0).

Fixed

  • RadiodControl.set_agc(attack_rate=...) was unreachable. It encoded StatusType.AGC_ATTACK_RATE, which does not exist in ka9q-radio's status.h or in ka9q/types.py — any call passing attack_rate= raised AttributeError. Replaced with a working threshold: kwarg backed by AGC_THRESHOLD (which radiod actually decodes in decode_radio_commands()).
  • Removed 6 stale duplicate set_* methods. In a single class, second defs silently shadow firsts — so callers were already using the correct versions further down the file. The dead first defs of set_squelch, set_pll, set_output_channels, set_independent_sideband, set_envelope_detection, and set_opus_bitrate are gone. One of them (set_opus_bitrate) referenced a non-existent StatusType.OPUS_BITRATE — the working second def uses the correct OPUS_BIT_RATE.

Tooling / pinning

  • Pin advanced from ka9q-radio f78cff9c (1.0.0-22) to d555f1853422. Drift report confirms zero TLV-tag, encoding-enum, demod-type, or window-type changes across the 68 intervening upstream commits — only packaging, hydrasdr-driver, and internal C-struct refactors. Existing ka9q-python state (types.py, decode_status_packet, SpectrumStream, every set_* method) was already covering the full HEAD protocol surface; this release brings the recorded compatibility tag in line.

Tests

  • Fixed pre-existing tests/test_filter_edges.py::_bare_control helper that did not initialise the client_id attribute added with v3.14.0 per-(client,radiod) multicast destinations.
