The issue you’re experiencing with Platinum Notes—where a small portion at the beginning of each processed track is missing—is actually a known behavior in some auto-mastering tools, often caused by how the software trims silence or processes waveform analysis at the start of a file; this isn’t always “normal,” but it can sometimes be fixed by adding a short silence buffer before processing or adjusting export settings if available. If that doesn’t resolve it, you might consider alternative tools like Audacity or Adobe Audition, which offer more control over clipping repair, dynamics, and volume leveling without cutting audio unintentionally. Just like how users compare different platforms—for example checking menus on
kfcmeenu.co.za to find better options—you can explore multiple audio tools to see which one delivers the best mastering results for your needs.
