Script that applies HeSuVi virtual surround to 7.1 input files.

Binaural audio in a nutshell

• HeSuVi installed.
• Input sample rate needs to match HeSuVi HRIRs' (44100hz or 48000hz).

• Drag and drop file onto the script then press Enter, and follow the instructions.
• To change settings (HRIRs/output format/bitrate/extra arguments), press Enter without providing input.
  • Settings are saved to an INI file for future sessions.

• Extra WAV files in the script folder will be added as new tracks without applying extra virtualization, using filename without extension as label.
• Only input file's main video track will be used, and copied without re-encoding.
• Only input file's main audio track will be used, re-encoded only if required (MP4).
• While processing, HeSuVi will be turned on and cycle through HRIRs, which also applies to system audio.

You can use this script to:

• Add a pre-virtualized 7.1 track to a movie to watch on a portable device or on the go.
• Compare surround virtualization software:
  • Audio (Airtable) Recommended .OGG/OPUS audio format (Opus codec) and 128k bitrate.
  • Video (Vidyard) Requires .MP4 container, .M4A (AAC-LC) audio codec and H.264 video track. Also, avoid HRIRs with special characters like ssc_hù.wav.
