Denoise vs VocalDrop

Denoise is an audio cleanup app for Android and iOS that uses an on-device neural network to reduce wind, traffic, hiss, hum, and crowd noise in voice memos, interviews, and videos. Processing runs locally, including in airplane mode, and a one-minute clip typically takes 5–10 seconds. Users can import recordings from Voice Memos, Photos, Files, or an app share sheet; supported inputs include MP4, M4A, MP3, and WAV. The free plan lets users import, process, and hear a before-and-after preview, but saving and export require Pro. Pro can export M4A, MP3, or WAV, replace audio inside a video, restore detail in clipped, muffled, or distant recordings, and separate vocals from instrumental tracks on-device. Audio tools include a 5-band EQ with presets and automatic LUFS normalization. There is no file-length limit, including for recordings up to a three-hour lecture. Routes Software says recordings are neither uploaded nor stored, and the app has no user accounts. Google Firebase collects anonymous usage analytics and crash and diagnostic reports. Pro costs $2.99 a month or $14.99, paid once for lifetime access.

VocalDrop is a free desktop app that uses AI to separate vocals from songs stored on a computer. A separation can produce both an isolated vocal and an instrumental stem, for uses such as sampling, remixing, editing, or karaoke. Fast and Max modes use RoFormer-family models, with different models available for some hardware. The app can also extract audio from video, separate it, and place a selected stem back into a synchronized video. Users can paste links from YouTube, SoundCloud, Vimeo, TikTok, and more than a thousand other sites for fetching. Optional processing includes denoising, AI vocal restoration, silence removal, and audio-format conversion. The maker says track contents are processed locally and not uploaded. Separation can run offline after the required model download; enabling NVIDIA acceleration also downloads a one-time CUDA package. A command-line interface with JSON output supports pipelines. VocalDrop runs on Linux, macOS, and Windows, and its free plan lists no track limits, watermark, account requirement, or feature paywall. The maker says current builds are not code-signed or notarized and provides SHA-256 checksums for release assets.
