The per-listener noise-reduction toggle (vc_set_remote_stream) did nothing on Windows/macOS/iOS. The decode loop gated the RNNoise pass on dec_channels == 1 as a proxy for "this stream is voice" (assuming stereo => screen-share). The stereo-mic capture commit broke that: a stereo mic with send-side NR off transmits stereo Opus, so the receiver decoded two channels and skipped NR entirely. gain/mute have no channel guard, which is why only NR appeared broken. Thread the stream kind through init_recv_stream into RemoteStream::is_voice (set from si.kind() == STREAM_MIC), gate receive NR on is_voice instead of channel count, and fold a stereo voice frame to mono -> denoise -> duplicate back across both channels in place (symmetric with the send-side downmix; RNNoise is mono-only). Screen-audio shares are never denoised. New test test_recv_noise_reduction drives AudioEngine and asserts a stereo voice stream's noise floor collapses with NR on (RMS 1046 -> 0.1) while a screen-audio share stays unchanged. ctest --preset dev green 29/29.

VoiceCat
Self-hosted, native voice & text chat in the spirit of classic TeamSpeak / Mumble —
channel-based voice, channel + private text, one server you run yourself. Plain TCP
(control) and UDP (media), no WebRTC. Encrypted by default. A shared C++ core
(libvoicecat) drives native clients (Swift on macOS/iOS, C# on Windows) and the server.
Status: Design complete in
docs/. M1–M5 are implemented — real TLS control plane, encrypted UDP voice (Opus), multi-stream, TOFU identity pinning, channel tree, permissions, moderation, disconnect/keepalive/reaper. Windows WinForms C# client shipped (M4). macOS/iOS Swift client is next. SeePROGRESS.mdanddocs/roadmap.md.

Build
The default development preset is dev — it builds everything (server + tools + tests)
with real vcpkg deps. It works on Windows, Linux, and macOS (vcpkg triplet auto-resolved).
# one-time vcpkg setup:
git clone https://github.com/microsoft/vcpkg && ./vcpkg/bootstrap-vcpkg.sh # .bat on Windows
export VCPKG_ROOT=/path/to/vcpkg # Linux/macOS; or $env:VCPKG_ROOT on PowerShell
# configure + build + test:
cmake --preset dev
cmake --build --preset dev
ctest --preset dev # 21 behavior tests
Artifacts land in build/dev/bin/ (voicecat-server, vccli, voicecat-admin).
The skeleton preset (no vcpkg deps, stubs only) is a fast smoke check that needs no
third-party libraries:
cmake --preset skeleton && cmake --build --preset skeleton && ctest --preset skeleton
See docs/building.md for the full preset matrix (including release,
server-release, windows-client, and Apple platform scaffolding).
