Core Capabilities

⚡

Ultra-Low Latency Audio Pipeline

Our optimized AVAudioEngine implementation delivers audio with minimal latency. Watch movies without lip-sync issues.

  • Buffer Size 128-4096 samples (adjustable)
  • Sample Rates 44.1kHz, 48kHz
  • Typical Latency ~50-100ms total
🎚️

Input Gain Control (0-10x)

Many IFE systems output line-level audio (~30dB quieter than mic-level). Our input gain control lets you boost quiet sources up to 10x.

  • Range 0.0x to 10.0x (20dB boost)
  • Adjustment Real-time, no restart needed
  • Meter Post-gain level monitoring
🎙️

WAV Recording

Record USB audio input to high-quality WAV files. Perfect for capturing in-flight content or important announcements.

  • Format 16-bit PCM WAV

Advanced Controls

⚙️

Buffer Size Adjustment

Fine-tune latency vs. stability. Lower buffer = lower latency but higher risk of dropouts. Higher buffer = more stable but higher latency.

🎵

Sample Rate Selection

Match your IFE system's native sample rate for best quality and lowest latency.

📱

Background Mode
