Echobox player is an elegant, privacy‑minded audio player built for everyday listening. It respects your library, keeps folders as folders, and adds smart features that make long‑form audio a joy—chapters, effects, transcripts, and more—without getting in your way. Whether you’re listening to audiobooks, podcasts, lectures, or long mixes, Ecobox balances reliability with power. It runs great on‑device, handles big local libraries, and even plays live Internet radio. - Preserve folder structure: Import entire folders and keep your organization intact. EchoBox mirrors your file tree instead of flattening it. - Per‑file Relative Volume: Dial in the loudness of each file without permanently altering audio. Normalize your library tastefully—ideal for podcasts and audiobooks recorded at different levels. - Chapters done right: Fast chapter detection for m4a/m4b and MP3 (ID3 CHAP). Jump quickly via a clear, accessible chapter list and dedicated button. - Effects when you want them: Optional EQ, low‑cut, reverb, and a smart compressor powered by a robust AVAudioEngine path. Effects are off by default and won’t destabilize normal playback. - Storage awareness: A tidy footer shows used and free space so you always know when it’s time to declutter. - On‑device transcription: Generate timestamp‑aware transcripts from your audio using Apple’s Speech framework. Prefer on‑device models when available, with a clear live progress view. - Internet Radio (.radio): Save and play live streams with a simple .radio file. EchoBox optimizes controls for live playback and gets out of your way. - Swift, fast, and private: No accounts. No trackers. Your library stays on your device.
