A dedicated, lightweight Windows utility explicitly designed for measuring Wow and Flutter using standard test tapes. Conclusion
The application is typically priced at approximately $25 USD .
Use the software's built-in tone generator to output a 1kHz tone (for level/distortion mapping) or a 3kHz tone (for speed mapping).
