Finished your mix? Mastering Everest gets it ready to publish: it brings the loudness to the right level for the platform, keeps the peaks under the limit, creates the file in the format you need and checks it before handing it to you. WHAT IT DOES • Audio mastering for your tracks • Normalizes volume • Converts tracks to MP3, WAV, FLAC and AIFF • The right volume for Spotify, Apple Music, YouTube, social media, podcasts, web radio, TV and radio You choose where you publish. The app takes care of the rest. WHY IT MATTERS Every platform has its own loudness and peak targets. If a track is too loud, the platform turns it down. If the peaks are too high, the sound can distort after MP3 or AAC encoding. Mastering Everest brings your track to the targets of the platform you choose and checks the result. YOUR MIX STAYS YOURS • No EQ, no effects: it sets the loudness and, only when needed, brings the peaks down. • First it tells you what it will do: for example, lower the volume by 4.1 dB and reduce the peaks, or nothing at all. • If a track is already fine, it leaves it untouched. • If reaching the loudness would squash the sound too much, it stops and tells you why. HOW IT WORKS 1. Import your track from the Files app or from another app: WAV, MP3, M4A, AAC, FLAC, AIFF, OGG and OPUS, mono or stereo. 2. Choose where you publish it: Spotify, Apple Music, YouTube, social media, podcasts, web radio, TV and radio (EBU R128), archive (original volume). Or set your own values in Manual. 3. The app analyzes the track and shows its loudness (LUFS), its true peaks and what it will do. 4. Create the master. The app measures it again after encoding and tells you whether it is ready. EVERY MASTER IS CHECKED • Right loudness (LUFS) for the platform • True peaks within the limit, even after encoding • No distortion • Same length and correct format: a complete, intact file LISTEN AND DECIDE • A/B listening between the original and the master at equal loudness: you compare the sound, not the volume. • Waveform and spectrum views compare the two: see where the peaks were reduced and whether the tone has changed. • Hear the master after an encoding similar to the platforms': AAC, MP3 and Opus. • When your choice is needed, the app asks you. SEVERAL TRACKS, ALBUMS AND REPORTS • Several tracks in a queue, one after the other. • Albums: all tracks go up or down together, so a ballad stays quieter than a rock song, as on the record. • History with a report for every master, to share as a PDF. • Your masters are also in the Files app. EVERYTHING STAYS ON YOUR DEVICE Analysis and mastering happen on your iPhone or iPad: Mastering Everest never uploads your tracks to the internet. TRY IT FREE, THEN PAY ONCE • Analyzing tracks is always free. • 3 free masters, no account needed, in every format. A track that is already fine does not use up the trial. • Then choose: Lite exports MP3 320 kbit/s, Pro also WAV, FLAC and AIFF. Everything else is the same. • Bought Lite in the app? No need to buy it again: just upgrade to Pro. No subscription. Purchases work on all your iPhones and iPads with the same Apple Account. Mastering Everest does not replace mixing and promises no miracles: it does the final technical step with precision, and shows you what it did. A Radio Everest project. Spotify, Apple Music and YouTube are trademarks of their respective owners. Mastering Everest is not affiliated with them.
