I tested Trebble after purchasing it, hoping for a Descript alternative. Unfortunately, my experience was frustrating. I uploaded a simple 42-second audio file, and after waiting over two hours, the tool produced nothing—literally zero output.

I'm disappointed because I genuinely want this to succeed. The concept is exactly what I need, and I can tell the developer is working hard on it. However, for a tool that's been around for a while, the execution falls short of expectations. Basic audio processing should be reliable and reasonably fast.

The core functionality simply isn't working properly. Processing time is unreasonably long (or infinite, in my case), and there's no clear feedback on what's happening or why the audio processing while user waits. It actually showed 100% yet outputted nothing.

I'm requesting a refund for now. This isn't to discourage the developer. I genuinely hope they continue improving Trebble as it's the only reasonable alternative to Descript at the moment. However, I'll wait until I see verified reviews confirming the platform has become more stable and functional before investing again.
