Sonarium: Music Server & Tools

Sonarium is two apps in one: a native player for the music server you host yourself, and a workshop of twenty audio tools that run entirely on your iPhone. YOUR MUSIC SERVER, ON YOUR PHONE Point Sonarium at Navidrome, Airsonic, Gonic or any server that speaks the Subsonic API and your whole library is on your iPhone, your Apple Watch and your Mac. • Lossless streaming: FLAC and ALAC stay lossless, or pick 128, 192 or 320 kbps on cellular. • A real five-band equalizer with 15 presets and ReplayGain. • Lyrics that light up word by word, fetched before the song starts. Tap a line to jump to it. Shift the timing for Bluetooth lag, or translate under each line with your own Gemini key. • Made For You: mixes by time of day, mood and genre, each with its own cover. Instant Mix starts a radio from any song or artist. Year Wrapped counts your year. • Radar: this month's releases from the artists you play most. • Offline, all of it: download a song, an album, a playlist or the whole library. The library, search and playback keep working with no signal. • Several servers, home-network addresses, custom headers, multiple music folders. • Lock Screen, Control Center, Dynamic Island, AirPlay, a Home Screen widget, Siri and Shortcuts, SharePlay, Apple Watch. TWENTY AUDIO TOOLS, NOTHING UPLOADED Open the Tools tab and work on any audio file: a downloaded song, a file from Files, a voice memo you just recorded. Edit — Converter (AAC, WAV, AIFF, FLAC, ALAC, CAF) · Trimmer with waveform · Merger · Ringtone Maker (.m4r) · Fade Editor · Reverser · Silence Trimmer Shape — Tempo Changer (0.5× to 2×, pitch kept) · Pitch Shifter (±12 semitones) · Reverb Studio (9 rooms) · Vocal Remover for karaoke · Volume Booster and peak normalizer Live — Voice Recorder with a live meter · Metronome with tap tempo, scheduled on the audio clock · Chromatic Tuner with adjustable A4 · Spectrum Analyzer from the mic or a file Analyze — BPM Detector · Tag Editor with artwork · Transcriber (speech to text, on-device) · Audio Inspector (codec, bitrate, peak, RMS, clipping) Every tool runs on the phone. No account, no upload, no watermark, no limit on file length for the editing tools. Exports go to one folder and share to Files, AirDrop, Messages or any app. The tools work even before you add a server. PRIVATE BY DESIGN No account, no ads, no tracking, no analytics. Your server address and password stay in the iOS Keychain on your device. The privacy policy lists every public service the app talks to and why. Sonarium is a client, not a music service: it plays the library on a server you own or have access to. No server yet? Try the public Navidrome demo from the welcome screen.
