How to Use

  1. Upload any audio file — WAV, FLAC, AC3, EAC3, TrueHD, DTS, AAC, MP3, MP4
  2. The tool detects channel count and maps it to a speaker layout automatically
  3. Watch the virtual home theater — active speakers glow with real-time sound waves
  4. Use the Live Channel Meters to confirm each speaker channel has signal
  5. Use Quick Test Tones to verify your speaker setup without a file
  6. For Dolby Atmos / TrueHD files: browsers decode the base layer; overhead detection is based on file metadata
