Denoise vs Music Separator

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.

Music Separator is an Android and iOS app from UKGADGETS LTD in London that separates uploaded audio into vocal and instrumental parts. Its maker says neural networks analyze files, with training on millions of songs according to its FAQ. The app targets karaoke, singing practice, remixing, and music production. Playback controls include speed and key changes, plus separate volume controls for vocals and instruments. Synchronized lyrics appear when available, and processing history keeps earlier work accessible. MP3, WAV, M4A, AAC, and FLAC are listed as supported formats; iOS users can import from their music library. Audio is uploaded for cloud processing, and originals are automatically deleted afterward, according to the maker. Free users can process one file weekly without a card. Weekly costs $3.99 a month (billed $3.99 /week); Yearly costs $24.99 a year.
