A2V vs EchoBox Player

Social apps don't accept bare audio. A2V fixes that: it turns any audio clip — a voice memo, a song sketch, a podcast moment, a lecture — into a clean waveform video you can post to feeds, stories, and messages. Share it in seconds. From Voice Memos or any app, tap Share and choose "Convert to Video." Or open A2V to import from Files, record something new, or restyle an old clip. NINE VISUALIZATIONS Wave, Radial, Spectrum, Ribbon, and Spectrogram for classic audio looks — plus Aurora, Pulse, and Starfield, neon visuals that move with the sound and give every recording its own feel. MADE FOR EVERY PLATFORM Export Square (1:1), Vertical (9:16) for stories and short video, or Wide (16:9) for the big players. Pick your waveform and background colors to match your brand. ON-DEVICE CAPTIONS Auto-transcribe speech into burned-in captions so your words land even on mute. Captions are generated entirely on your device (requires iOS 26). A LIBRARY, NOT A ONE-SHOT Every render is saved. Replay it, rename it, share it again, or make a New Version in a different style — without re-importing the audio. PRIVATE BY DESIGN No account. No uploads. No tracking. Recording, transcription, and rendering all happen on your device. Your audio never leaves your phone. ALSO - Live preview before you render - Record straight into the app - Universal — iPhone and iPad - A Shortcuts action: "Convert Audio to Video" - Handles long imports smoothly A2V is free to use. A one-time in-app purchase removes the small watermark (and it's already free for long-time users — thanks for sticking around).

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.
