STL Radio Link Decoder

Home PC Software

Broadcast Quality Audio Decoder

The Escape PCM STL Radio Link Decoder seamlessly receives uncompressed stereo audio over IP and delivers it to any standard sound card. Designed as the companion to the Escape Encoder, it provides professional-grade reliability for studio-to-transmitter links (STL) and continuous 24/7 broadcasting.

Applications

The decoder is ideal for remote transmitter sites where stable, high-quality reception is critical. It is equally suited for live broadcasts, ensuring near real-time performance with smooth playback and minimal latency under varying network conditions.

Key Features

  • Receives uncompressed PCM stereo audio at 44.1 kHz / 48.0 kHz.
  • Configurable audio output device, receiver port, and sound card latency.
  • Adjustable Audio Delay with Buffer Size and Audio Sync Delay settings.
  • Buffer Limiter prevents drift by keeping playback stable.
  • Refresh on Low Buffer protects against dropouts by realigning the buffer automatically.
  • Last used settings are saved on exit and restored at startup.
  • Supports auto-start streaming and system tray operation for 24/7 uptime.
  • Real-time Left/Right VU meters for accurate monitoring.

Challenge & Solution

Remote broadcasting often faces unstable networks and fluctuating latency. The Escape Decoder addresses these issues with advanced buffering controls, ensuring smooth and uninterrupted playback. Together with the Escape Encoder, it forms a complete IP-based STL solution that replaces costly traditional methods with a simple, reliable, and professional system.

License

The software license is valid for a single activation on one computer. If the decoder is moved to new hardware, a new license is required to ensure secure and professional-grade usage in broadcast environments.
