BMS WAV Vol Converter

Upload a ZIP of WAV files and shift every file by the same amount, in dB. Sample rate, bit depth and channel count are kept as they are.

STEP 1 — Upload your ZIP file

Accepted format: .zip (max 100 MB)
Every .wav in the archive is processed, including files inside subfolders. Folders are flattened, so the output is a single flat ZIP. Other file types are ignored.

Limits

  • Archive: up to 100 MB
  • Files: up to 2,000 WAV files
  • Expanded size: up to 200 MB total, 100 MB per file
  • Two files that would produce the same name are rejected — rename one and try again
  • Results are deleted 1 hour(s) after the job finishes
