What BadloVoice is
BadloVoice is a real-time AI voice changer for browsers and Android, intended for Discord, games, streams, and calls. Its README says audio processing stays on the user's machine rather than uploading voice to the cloud. Simple mode offers presets, pitch adjustment, and recording; Pro mode adds device controls, VU and spectrum displays, latency modes, and an effects rack. Users can load .pth, .pt, or .onnx voice models with a companion .index file and switch model slots. The listed effects include gate, robot, whisper, telephone, distortion, bitcrush, chorus, echo, reverb, EQ, and compressor. A converter accepts WAV, MP3, FLAC, OGG, and M4A files and produces processed WAV audio. The README documents routing audio to Discord and games through a virtual audio cable and also mentions OBS. The project is free and MIT licensed. Desktop quick-start requirements list Windows, macOS, or Linux, Python 3.11+ recommended, and Node.js 20+; an NVIDIA GPU with CUDA is optional for faster RVC or ONNX processing. An Android debug APK can be built with Android SDK and Gradle. iOS setup requires a Mac and Xcode, but no iOS release is described.
Good
- Audio processing stays on the user's machine.
- Simple mode includes presets, pitch adjustment, and recording.
- Pro mode includes device controls and an effects rack.
- Converts several audio formats to processed WAV.
- MIT licensed and free.
Watch out
- iOS setup requires a Mac and Xcode.
- No iOS release is described.
- Desktop quick start recommends Python 3.11+ and Node.js 20+.
Who it suits
It suits people who want local voice processing, presets, adjustable pitch, or more detailed audio controls for calls, games, or streams. Users considering iOS should note that the README describes setup requirements but not an iOS release.
Verdict
BadloVoice combines voice changing, recording, model loading, and file conversion, with processing kept local according to its README. Check the platform notes and desktop requirements, especially if you need iOS availability.
