ClipPlayer opens a rodio default sink, which on Linux reaches the graph
through PipeWire's ALSA plugin. It was untagged through all of phase 1,
and it is a real echo path: B broadcasts music, A tunes in, A shares
their desktop, B hears their own track played back at them. Confirmed
live as `alsa_playback.peerspeak-...` with no ownership properties.
rodio exposes no way to set PipeWire node properties, so the carrier is
PIPEWIRE_ALSA, set once at the top of main while still single-threaded.
Measured, with PIPEWIRE_PROPS and PULSE_PROP unset, to establish that
setting it process-wide is safe:
- aplay (ALSA plugin) -> both carriers land. Confirms the mechanism.
- pw-play (native) -> untouched. Our own call-playback and capture
streams are native, so they keep their own
explicit tagging and are unaffected.
- arecord (ALSA capture)-> IS tagged, on a Stream/Input/Audio. Not
surgical in the role dimension; harmless only
because R10-1 honours the carriers on
producers alone. This is why R10-1 lands first.
Local playlist tracks are tagged too, not just inbound peer audio. A
local track is already broadcast to peers over the call on the same
keypress, so sharing it again through the screen share would send the far
end two copies at differing latency. That is a defect, not a feature.
Codex phase-1 review F1. Round 10, R10-2.
New live exit-gate row drives the real ClipPlayer; mutation-verified
(drop the tag -> no node within 5s). The wiring guard is mutation-
verified too, and its first version was WRONG: it searched raw source and
passed against a main with the call deleted, because the comment above it
named the function. It strips comments now.

PeerSpeak
Decentralized, peer-to-peer voice chat — full-mesh, NAT-traversing, with no central server. Built in Rust on iroh (QUIC), PipeWire audio, the Opus codec, and an iced GUI.
Create a room, share the join ticket, and talk. Everyone connects directly to everyone else; relays are only used to punch through NATs when a direct path isn't available.

Features
Rooms & sessions
- Create a room → shareable join ticket; join by pasting a ticket.
- Full-mesh multi-peer rooms with live presence.
- Recent-rooms list to hop back into a room someone's still in.
- Remembered nickname and in-call duration timer.
Audio
- PipeWire capture/playback, selectable input and output devices, per-app gain.
- Opus codec (48 kHz mono, 20 ms frames) with an adaptive jitter buffer + packet-loss concealment.
- Noise gate with a draggable threshold on a live mic meter (test your mic off-call too).
- Mix-bus soft limiter and opt-in echo cancellation (PipeWire WebRTC AEC + noise suppression).
Voice controls
- Self-mute, deafen, and rebindable push-to-talk.
- Per-peer volume, local mute, and speaking indicators.
Text chat
- In-room text chat over the gossip plane, with clickable links and inline image/audio attachments.
- Drag-selectable, copyable messages; right-click context menu on all text fields.
Shared music listening
- Build a personal playlist of local audio files with a full transport (play/pause, seek, reorder).
- Let others tune in: peers stream your current track, timeline-synced and gapless, sitting under voice at their own volume.
Screen share (via pixelpass)
- Share your screen; peers click 👁 Watch to open the stream in mpv (vlc fallback).
- Live badges on sharing peers; per-app audio capture.
Recording & notifications
- Local call recording (mic + incoming mix → WAV in
~/peerspeak-recordings/). - Desktop notifications and event chimes with per-event custom sound overrides.
UI & networking
- Selectable room layouts (3-Column, Bottom Dock, Drawer) with draggable, persisted dividers.
- 10 built-in themes (Catppuccin, Dracula, Nord, Tokyo Night, Gruvbox, Solarized…), all WCAG-AA checked.
- Network mode picker (relay-no-discovery default, full n0, or direct-only); retained-address reconnect.
- Config, window size/position, and all preferences persisted to
~/.config/peerspeak/.
See docs/FEATURES.md for the full inventory and field-test status, and docs/ARCHITECTURE.md for internals.
Roadmap
- Contacts & invites — friends list with invite-notification one-click join (design in
docs/contacts-plan.md). - Spatial audio & per-peer EQ.
- Soundboard — play short clips into the call mix.
- Room persistence / invite links beyond the raw ticket.
- Windows support — cross-compiles and launches under Wine today; needs a real WASAPI audio pass (see
docs/WINDOWS.md).
Building
PeerSpeak builds with a stable Rust toolchain (edition 2024). Install the system dependencies below, then:
cargo build --release
./target/release/peerspeak
System dependencies
Arch Linux
sudo pacman -S --needed rust pipewire opus pkgconf git
Debian / Ubuntu
sudo apt install build-essential pkg-config clang libclang-dev \
libpipewire-0.3-dev libopus-dev libasound2-dev libxcb1-dev
Plus a Rust toolchain via rustup. clang/libclang are needed for the PipeWire bindings (bindgen).
At runtime you need a running PipeWire server. Screen sharing additionally requires pixelpass on your PATH, and mpv (or vlc) to watch a peer's share.
Packaging
- Arch:
cd packaging && makepkg -si(usespackaging/PKGBUILD). - Debian/Ubuntu:
.debis built withcargo-debfrom the[package.metadata.deb]block inCargo.toml. Build inside a Debian/Ubuntu environment so the binary links that distro's glibc. - Windows: see
docs/WINDOWS.md.
