Sonic Refine is a Windows app that cleans your voice recordings and videos in one click. It removes noise, breaths (even the fake ones AI voices add) and dead air, then evens out loudness. For video, it compresses big files, converts formats, and turns 16:9 into 9:16 by following the face. AI runs on your own CPU, so nothing is uploaded: no queue, no GPU, no per-hour bills. Made for AI voice creators, podcasters and editors. Free for 2 hours a month, no account needed.
