Streaming Platforms Reject Them.
Suno v5 has a characteristic "mud" in the low-mids that makes tracks sound boxy and unprofessional.
Streaming platforms normalize to -14 LUFS. Upload at the wrong level and your track sounds quiet or distorted.
AI-generated tracks often have phase problems and narrow stereo images that sound flat on speakers.
You spent hours crafting the perfect prompt. The AI delivered something amazing. But when you upload to Spotify, it sounds like it was recorded in a cardboard box. Your fans deserve better.

"I was uploading my Suno tracks directly to Spotify and wondering why they sounded so different from other songs. Mastera fixed everything in literally 30 seconds."
"I create 10+ tracks per week for my YouTube videos. The batch processing alone saves me hours. And my tracks actually sound professional now."
"I have zero audio engineering knowledge. With Mastera, I just move three sliders and my tracks sound like they belong on Spotify. It's magic."
Not at all. Mastera was designed for musicians, not engineers. Our presets handle the technical stuff. You just move sliders until it sounds good to you.
