Quick start

Get TCP Streamer running in minutes. Follow these steps to start streaming audio to your TCP server.

1

Download and install

Download the latest release for your platform from the releases page.
  • macOS: Open the .dmg file and drag to Applications
  • Windows: Run the .msi or .exe installer
  • Linux: Install the .AppImage or .deb package
2

Select your audio source

Launch TCP Streamer and choose the audio input device you want to stream.For system audio capture:
  • Windows: Enable “Loopback Mode (Windows)” to capture system audio via WASAPI
  • macOS: Use BlackHole or similar virtual audio device
  • Linux: Configure PulseAudio or ALSA loopback
3

Configure your destination

Enter your TCP server details:
Example Configuration
IP Address: 192.168.1.100
Port: 4953
Sample Rate: 48000 Hz
Buffer Size: 1024 samples
For Snapcast servers, use port 4953 (default TCP streaming port).

Start streaming

Click Start Streaming and monitor the real-time statistics:
  • Connection status and uptime
  • Current bitrate and data sent
  • Network quality score and jitter
  • Buffer health and latency
Enable Auto-reconnect to maintain connection stability, and Auto-start on launch to run at system boot.

Core features

Built for reliability and performance with advanced audio streaming capabilities.

Real-time TCP streaming

Stream raw PCM audio over TCP with sub-millisecond timing precision using token bucket pacing.

Silence detection

RMS-based silence detection automatically stops transmission to save bandwidth when no audio is playing.

Adaptive buffering

Dynamic buffer sizing adjusts to network jitter in real-time, preventing dropouts on WiFi and unstable connections.

Configuration profiles

Save and switch between multiple configurations for different streaming scenarios and destinations.

Cross-platform support

Native system audio capture on Windows (WASAPI), macOS (CoreAudio), and Linux (ALSA/PulseAudio).

Network optimization

QoS tagging (DSCP/TOS), high-priority threading, and network presets for Ethernet, WiFi, and poor connections.

Use cases

TCP Streamer integrates seamlessly with multi-room audio systems and custom audio pipelines.

Snapcast integration

Stream audio to Snapcast servers for synchronized multi-room playback across your home or business.
