WAV to MP3: Audio Converter

Convert your WAV files to MP3 directly on your iPhone or iPad. Everything happens on the device: your audio is never uploaded to a server.

PRESETS TO GET STARTED Six ready-made settings: Balanced, Voice, Small file, High quality V0, Maximum compatibility and Maximum CBR 320. Pick one and convert.

PROFESSIONAL CONTROL WHEN YOU NEED IT

• VBR or CBR encoding, up to 320 kbps
• VBR quality V0 to V9 and encoder quality 0 to 9
• Sample rate from 8 kHz to 48 kHz, or automatic
• Mono, stereo, joint stereo or automatic

REAL MEASUREMENT, NOT GUESSWORK Every file is analysed before conversion, and the app shows integrated loudness in LUFS and true peak in dBTP. Normalize to peak −1 dB, to −14 LUFS or to the podcast target.

NON-DESTRUCTIVE EDITING Trim on the waveform, apply fade in and fade out, and preview the selected range before converting. Your original WAV is never modified.

METADATA AND ARTWORK Edit title, artist, album, year, track, genre and comment, and add cover art. The MP3 comes out fully tagged.

SEVERAL FILES IN A ROW Add a selection or a whole folder and the app converts them in a sequential queue, showing every phase: preparing, analysing, encoding and verifying. Cancel whenever you want.

VERIFIED OUTPUT Every MP3 is reopened and checked before it is saved. If anything fails, the partial file is removed and your original is left untouched.

HISTORY Play, share, save, rename or re-convert any result. Your history stays available even if the subscription lapses.

INPUT FORMATS WAV RIFF, RIFX, RF64, W64 and extensible WAV. Conversion is streamed, so very long recordings work too.

PRIVACY
