Null Player vs Wavelength Pro Audio Editor

Null plays the audio files you already have, MP3, M4A, AAC, WAV, AIFF, FLAC, whatever you've got, without an account or an internet connection. Import files from the Files app and Null reads the title, artist, artwork, and length straight off the file itself. Build playlists, reorder them, give them a cover photo, hit play or shuffle. The full-screen player has a soft moving backdrop pulled from the album art. Lock screen and Control Center work the normal way. skip, pause, resume, without opening the app. There's no account system, no analytics, no ad network. Nothing about how you use Null goes anywhere but your own phone.

Wavelength is a classic waveform audio editor for people who record, edit, and send audio every day - journalists in the field, clinicians, podcasters, anyone who lives on a waveform. Record a take, trim it on the wave, clean it up, mark the quotes, and export at the right level. It works the way desktop wave editors always have - a big waveform, menu-driven editing, and the keyboard habits your hands already know - rebuilt as a fast, native app for iPhone and iPad. RECORD - Record straight from the microphone with live meters and a scrolling waveform. - Every take autosaves to a Vault - nothing is ever lost, and you can reopen any recording from Open Recent. EDIT ON THE WAVEFORM - Cut, copy, paste, mix, crossfade, and trim directly on the wave. - Deep undo, so you can experiment without fear of losing the take. A FULL PROCESSING MENU - Normalize, fade in/out, time stretch (pitch-preserving), pitch shift, reverse, and DC-offset removal. - Loudness normalize toward broadcast levels for delivery. MARKERS, REGIONS & DELIVERY - Drop markers and define regions to mark the moments that matter. - Export regions, or the whole file, to WAV, MP3, or AAC - at the level the other end expects. MORE - A separate multitrack view (four lanes, clip blocks, volume envelopes, mixdown) for assembling packages. - Eight interface themes, from dark slate to porcelain. - Keyboard-first: J/K/L shuttle, space transport, the classic key habits. Wavelength has no account and no sign-in. Your recordings stay on your device - nothing is uploaded, no analytics, no tracking.
