Neon Engine vs RIP DJ

Transform your music into a sound that feels uniquely yours. Neon Engine is an on-device audio workshop for reshaping local music with immersive effects. Import a track, preview different styles, fine-tune the result, and save it to your personal library—all directly on your iPhone. -- AUDIO MODES -- Bass Enhance: Add more weight and depth to your music with a stronger low-end sound. Slowed + Reverb: Adjust the tempo, tone, and reverb to create a deeper, more atmospheric mix. City Pop: Give your track a bright, nostalgic character inspired by retro nighttime soundscapes. Fast Tempo: Speed up your music with adjustable tempo controls, from a subtle lift to a high-energy remix. Original: Save and manage the original track alongside your converted versions. -- BUILT FOR YOUR MUSIC -- Live Preview: Hear each effect before saving and fine-tune supported modes in real time. Personal Library: Organize converted tracks, rename them, filter by effect, and mark favorites for quick access. Bulk Actions: Select multiple tracks to update favorites or delete them together. Files Integration: Import compatible audio files directly from the iOS Files app. Background Playback: Continue listening to tracks from your Neon Engine library outside the app. -- PRIVATE BY DESIGN -- Your music stays on your device. Audio processing is performed locally without uploading your files to a remote server. Neon Engine is designed for local audio files you own and for personal, creative use.

RIP DJ is a spectrogram tool for DJs. Drop in any track — MP3, FLAC, WAV, AAC, M4A, OGG, Opus — and RIP DJ analyzes its full spectrum on your device. A live spectrogram and waveform appear while the track plays, and a full-track spectrogram renders once the scan completes. Share the spectrogram image with track metadata to any app. The FFT runs entirely on your phone. No uploads, no accounts, no analytics. Files you analyze never leave the device. The app makes no network requests at all. https://www.ripdj.com/privacy https://www.ripdj.com/terms
