Adds Config.DisableUDP field. When set:
- DialWithDialer skips startUDP() entirely (no UDP socket, no UDP reader)
- WriteAudio skips WriteAudioUDP and goes straight to TCP-tunneled audio
Useful for debugging crypto/transport issues — rules out UDP-specific
problems like NAT, firewall, or OCB2 counter mismatches.
Adds a --tone-test flag that bypasses all OpenAL/soundcard
initialization and instead:
- Generates a 440 Hz sine wave at 48kHz mono, encodes it via Opus,
and sends it to the Mumble server.
- Saves all incoming decoded audio to a raw PCM file (s16le,
stereo, 48kHz) specified by --tone-out (default: incoming.pcm).
Useful for end-to-end testing of the Opus encode/decode pipeline
and Mumble transport without requiring physical audio hardware.
Usage:
barnard --server HOST --tone-test --tone-out /tmp/in.pcm
ffplay -f s16le -ar 48000 -ac 2 incoming.pcm
When -auto-transmit is passed, barnard automatically keys up the
microphone as soon as the connection sync completes. Useful for
testing, bots, and unattended operation.
Usage:
barnard -auto-transmit -server=mumble.example.com -username=test_bot
The -logfile flag writes log output to a file in addition to stderr,
so users can run barnard in the TUI without log spam on screen.
Usage:
barnard -log=debug -logfile=/tmp/barnard.log -server=mumble.example.com
Add a lightweight log package (log/log.go) with debug/info/warn/error
levels. Wire it up via a -log flag (default: warn). Logging covers:
UDP transport:
- Socket open/failure, CryptSetup receipt, crypto initialization
- First UDP audio send confirmation
- UDP read errors and packet counts
- TCP fallback reason (no socket, waiting for crypto)
Audio pipeline:
- Source (mic) routine start with config details
- Audio stream start/end per remote user
- First audio stream creation for each user
- Packet loss detection with sequence gaps and PLC generation
- Decoder reset on sequence reordering
Usage: barnard -log=debug -server=mumble.example.com
Levels: debug, info, warn, error
Implements 7 voice effects that can be cycled through with F12:
- None (default)
- Echo: Single repeating delay with feedback (250ms)
- Reverb: Multiple short delays without feedback
- High Pitch: Chipmunk voice using cubic interpolation
- Low Pitch: Deep voice effect
- Robot: Ring modulation for robotic sound
- Chorus: Layered voices with pitch variations
The effects are applied after noise suppression and AGC in the audio
pipeline. Selected effect is persisted to config file. Includes
comprehensive documentation in README.

Changed handle_error to accept *Barnard pointer instead of copying struct by value, eliminating race condition warnings from mutex copying.
