MP3 to WAV Audio Converter

MP3 to WAV turns MP3 files into uncompressed PCM WAV audio directly on your iPhone or iPad. The conversion engine runs on the device, so your recordings, file names and tags never leave it. Built for the moment a tool refuses your MP3: a DAW session, a video editor, a sampler, a CD image, a voice dataset or an older piece of hardware that only accepts WAV. OUTPUT PRESETS - Original compatible: keeps the source sample rate and channels, 16-bit PCM - CD: 44.1 kHz, stereo, 16-bit PCM - Studio: 48 kHz, stereo, 24-bit PCM - Voice: 16 kHz, mono, 16-bit PCM - Custom: build your own and save it for next time CONTROL OVER THE OUTPUT - Sample rates from 8,000 to 192,000 Hz with high quality resampling - Mono, stereo, or the source channel layout - 8, 16, 24 and 32-bit PCM, plus 32-bit float - Optional triangular dither when reducing bit depth - RF64 output so results above 4 GiB stay valid - LIST/INFO metadata carried over from the source when you want it EDIT BEFORE EXPORTING - Waveform view with draggable trim handles - Play back the selected range before you commit - Fade in and fade out - Gain adjustment or peak normalization, with clipping protection BATCH CONVERSION - Convert a whole selection in one pass - Give each file its own trim, level and output format - Files are processed one after another, and a single failure never stops the queue - Name collisions resolve automatically with (1), (2) suffixes - Name results by original title, title plus preset, or date plus title AFTER THE CONVERSION - Pick the folder where results are written - History with search and filters, plus retry, share, reveal and delete - Import from Files, by drag and drop, or straight from the share sheet - Long queues keep running in the background, and interrupted work restarts cleanly PRIVACY No account, no analytics, no third-party crash reporting and no network access. The diagnostics report you can export holds version numbers and job counters only, never file names, paths, tags or audio. WORTH BEING CLEAR ABOUT WAV avoids a second lossy encoding step and fixes compatibility with tools that reject MP3. It does not restore detail that MP3 compression already discarded. This app is precise about what it does.
