💎 Professional Audio Features

🔊 Gain Control & Normalize

  • Gain Slider: Manually boost the recording volume up to 10×.+1
  • Normalize: Automatically adjusts the volume to a professional -0.5 dB peak. This feature is intelligent—it ignores background noise and only boosts actual content.+1

🔴 CLIP Indicator & Reset

If the incoming signal is too loud and risks distortion, the CLIP light will turn red.

  • Studio Rule: If the CLIP light is on, consider lowering the Gain.
  • Reset: Use the Reset Clip button to clear the warning after adjusting levels.

🍦 Soft-Knee Compressor (Always On)

Your recordings are protected by a studio-grade Soft-Knee compressor. Instead of harsh digital clipping, it gently “softens” loud peaks above 0.75, resulting in a smoother, more analog sound.+1

🔇 Auto-Silence Skip

Enable this to prevent recording long periods of silence.

How it works: If no audio is detected for more than 2 seconds, the app intelligently pauses data capture, saving significant disk space

  • simple
  • accurate
