Features

Built for seamless broadcast integration.

🎙️

Bit-Perfect Audio Capture

Supports AudioScience (ASI) cards to bypass the Windows mixer, alongside modern WASAPI (WheatNet-IP, Dante, Livewire) and legacy DirectSound drivers.

🎛️

Hardware Triggering

Automate your recordings directly from your console. Native TCP integration for Wheatstone WheatNet-IP (SLIOs) and Serial COM integration for Broadcast Tools (GPI-16/24).

💾

Efficient Encoding

Save massive storage space with modern OPUS and VORBIS (.ogg) compression, or maintain maximum compatibility with standard MP3 and lossless Linear WAV formats.

⏱️

Flexible Recording Modes

Record 24/7 with automatic hourly file splitting, limit recordings to specific days/hours, or use dynamic GPI window logic to record only when triggered during scheduled shows.

📊

Real-Time Web Interface

Monitor live channel VU meters, trigger logic states, and system diagnostic logs remotely via a web dashboard*.

🔊

Mono Downmixing

Cut your storage footprint in half with automatic Stereo-to-Mono hardware downmixing.

Interface Gallery

Live Channel Management

Easily configure unlimited** virtual recording channels. Assign custom input devices, set your desired compression bitrate, and monitor live audio levels with dynamic, real-time VU meters directly in your browser.

Hardware Logic Integration

Link physical events to your audio logger. Configure Wheatstone WheatNet-IP SLIOs or Broadcast Tools GPI via serial connection. Add hardware logic, name them, and map them to start/stop any recording channel automatically.

Real-Time Diagnostics

Never guess if your triggers are working. The Live Hardware Status tab provides visual badge indicators for every physical input pin or network SLIO. Plus, view the raw background processing logs in real time.

Supported Audio Engines

AudioScience (ASI): Multi-stream 16-bit uncompressed PCM capture with dedicated driver memory pooling.
WASAPI (Windows Audio Session API): 32-bit Float low-latency capture for Dante, Livewire+, WheatNet, and modern USB hardware.
DirectSound: Legacy fallback wrapper for older broadcast systems and generic hardware.

Output Formats & Specs

OPUS (.ogg): 32kbps to 320kbps via FFmpeg wrapper. Ideal for high-efficiency, long-term archiving.
VORBIS (.ogg): High compatibility production format for native Adobe Audition integration.
MP3 (.mp3): 128kbps to 320kbps LAME encoded format for universal playback.
WAV (.wav): 1411kbps bit-for-bit uncompressed linear PCM.
