About Hangzhou Huanyin Technology
We're a small team focused on audio and audio-video creator tools for iOS and iPadOS — bringing desktop-DAW-grade capability into a one-handed mobile experience.
What we make
Our flagship product is AudioCutPro, an all-in-one audio studio for iPhone and iPad: waveform trimming, speed and pitch shifting, multi-track editing, AI vocal separation, denoise, video audio extraction, ringtone making — 20+ capabilities in total. The overwhelming majority of features run entirely on-device, ready to use out of the box.
Our approach
99% of processing happens on your device. No uploads, no profiling, no third-party ad SDKs.
Only segments you explicitly send to AI Vocal Separation leave the device, and they're erased server-side immediately after.
Capabilities once exclusive to professional DAWs, now in a one-handed mobile experience.
