Your books.

Ch. 01 — The Shelf

Two pantries. One kitchen.

Point Meringo Listen at a folder of M4Bs and MP3s, sign into your Audiobookshelf server, or do both. Local files and server books land on the same shelf, sorted the way you actually listen: in-progress at the top, recently added next, finished in the long tail.

A small badge marks which copy is local and which is on the server, for the listener who cares about the difference. Everyone else just sees their library — calm, current, and exactly where they left it.

Ch. 02 — Audiobookshelf

Your server, finally native.

A native Android client for Audiobookshelf, built in Compose with no web-shell seams. Real two-way position sync. Real offline downloads. Multi-server, multi-library. And real conflict resolution when two devices diverge — “your server is ahead of this device by 35 minutes” — so you never lose your place to a race condition.

Your bearer token is stored encrypted in the Android Keystore, and your device talks straight to your server — nothing proxies through us. Downloads land in the same on-disk layout the official client uses, so your files migrate cleanly.

Ch. 03 — The Voice EQ

A real EQ, tuned for the voice.

Six presets built for the situations spoken word actually lives in — Deep Voice Clarifier, Bright Headphones Tame, Phone Speaker, Late Night Soft, Neutral, and Subway, which pairs an EQ shift with a real downward compressor so narration sits steady when the train doesn't.

Add a one-tap Noisy-room boost — Subway, Stroller, Kitchen — for the moments the world gets loud. It's the same 64-bit double-precision engine that ships in Meringo Music, re-tuned for narration.

Go deeper

Ten bands. Yours to tune.

Want the controls, not just the presets? The Workbench gives you all ten parametric bands by hand, with a live curve. Paste an AutoEQ profile and Meringo Listen maps it onto the cascade. Build the sound once; it's there every time you come back.

Ch. 04 — Per-narrator memory

Save the voice. Recall the sound.

Find the curve that makes a narrator sound right, and Meringo Listen remembers it. Start another book by the same reader and it asks: “Last time you listened to Eleanor Voss, you used Late Night. Restore it for this book?”

No other audiobook player on either platform ships this. It lives entirely on your device — no preset cloud, no account, no telemetry. Tap Restore and stop thinking about EQ for the rest of the book.

A reader's voice is consistent across books. Your tuning should be too.

Ch. 05 — Speed

3× that still sounds like English.

Meringo Listen uses libsonic — the AOSP speech-optimised time-stretch, engineered by Bill Cox specifically for listening above 2×. Below 2× it leans on a high-quality WSOLA variant; at 2× and up it switches to a pitch-period algorithm that keeps sibilants crisp and dramatic pauses intact.

Most Android players run a music-app time-stretch that smears consonants at high speed. This one doesn't — and at 1.0× it's a clean passthrough, so nothing touches the audio you didn't ask it to.

0.5× – 3.0× libsonic Pitch-corrected 20–31 ms latency

Ch. 06 — Listen anywhere

Lose your place. Never.

Pause for a meeting and Meringo Listen smart-rewinds to the last natural pause when you come back — far enough to find the sentence, not so far you re-hear a paragraph. Force-stop the app, reboot the phone, reinstall a week later: the queue, the position, the speed are all exactly where you left them, and it waits for your tap before any sound.

Drift off with the Sleep Mode envelope — a gentle fade and screen-dim, end-of-chapter aware, that never nags. Drop a bookmark on a passage worth keeping; it stays on your device, exportable. Android Auto and chapter-aware Bluetooth controls come along for the drive.

Ch. 07 — Honest audio

Honest to the metal.

Tap the route badge and Meringo Listen tells you the truth about your audio path. When nothing is touching the bytes, it reads BIT-EXACT. Turn on speed, a compressor, or volume scaling and the badge decorates rather than lies — Speed 2.5×, LRC Subway, Scaled −2 dB.

For most audiobooks this is a quiet detail. For the listener who imported a 24-bit / 96 kHz audio-drama production, it's the whole point — the same honest engine, and the same route badge, that ships in Meringo Music.

Don't take our word. Read the diagnostics.

A built-in Diagnostics screen lays out the exact playback chain — sample rate, bit depth, output route, focus state — and exports it as a forum-ready card. The claims on this page are the claims the app makes about itself, on your device.

The honest part

Is Meringo Listen for you?

We'd rather you read this and bounce than download and refund.

Built for you if…

  • You own your audiobooks — locally, on a server, or both.
  • You self-host Audiobookshelf and have squinted at the official Android client.
  • You keep an M4B / MP3 archive and you're tired of an interface from 2014.
  • You've ever rewound because a notification or a noisy train swallowed a sentence.
  • You've ever wished a player would remember the EQ you set for a narrator.
  • You're on a 2022-or-newer Android phone, or a FiiO DAP from the M11 generation on.

Not for you if…

  • You primarily listen to Audible — AAX is DRM and we don't decode it. Ever.
  • You want a catalog or a subscription to discover books in. There isn't one.
  • You need Dropbox, Google Drive, or OneDrive sources. Server or local files only.
  • You're an F-Droid purist who won't pay for closed-source. (Try Voice — it's great.)
  • You're on iOS. Prologue, SoundLeaf, ShelfPlayer and AudioBooth already serve you.
  • You want streaks, leaderboards, or gamification. A calm yearly digest is the whole stats surface.

Built by one person, on the same engine as Meringo Music. The rule is the same: claim less than the code does, lead with what it won't do, and never make the listener pay rent for software they already bought.

Before you ask

A few things worth knowing.

Can Meringo Listen play my Audible books?

No. Audible's AAX files are DRM-protected and Meringo Listen does not decode them — that's a deliberate, permanent choice, not a roadmap item. It's built for books you own DRM-free: downloaded from a retailer like Libro.fm, ripped yourself, or served from your own Audiobookshelf library. If your library lives in Audible, stay with Audible.

Do I need an Audiobookshelf server?

No. Point Meringo Listen at a folder of audiobooks and everything works — playback, chapters, voice EQ, speed, bookmarks, sleep timer. Audiobookshelf is a first-class option for people who self-host, not a requirement. Local files and server books sit on the same shelf.

Which formats does it play?

M4B, MP3 (including ID3v2 CHAP chapter frames), M4A, AAC, OGG/Opus, FLAC, and WAV. Chapter navigation works from container metadata, MP3 CHAP frames, and Audiobookshelf's server-provided chapter lists.

Is there a subscription?

No. $14.99 once, then it's yours — after a 14-day free trial of the full app. If you reinstall or switch phones, your purchase restores automatically against your Google account. No ads, no premium tier behind a second purchase.

Does it track me?

No analytics SDK, no ad SDK, no engagement metrics, no listening data sent anywhere. Crash reports through Sentry are opt-in and off by default, and your server URLs are redacted before any crash payload leaves the device. Your Audiobookshelf server and optional Sentry are the only outbound connections.

How does it compare to Smart AudioBook Player or Voice?

Smart AudioBook Player has owned local-files Android for years and earned it — but its EQ and pitch controls sit behind a subscription, and 2026 reviewers call the UI dated. Voice is excellent, free and FOSS, deliberately minimal — with no EQ. Meringo Listen is the paid, premium-aesthetic option with a 64-bit voice EQ, per-narrator memory, and first-class Audiobookshelf. Different trade-offs; all three can exist.

Is this the official Audiobookshelf app?

No. Meringo Listen is an independent third-party client and is not affiliated with or endorsed by the Audiobookshelf project. The official client is free and will keep existing; this is a paid, native-Compose alternative for listeners who want a premium client. Your device talks directly to your server — nothing proxies through us.

Can I stream from Dropbox, Google Drive, or OneDrive?

No. The source list is Audiobookshelf and local folders (via Android's Storage Access Framework). Dropbox is under consideration for a later update; Google Drive and OneDrive are not on the roadmap.

Will there be an iOS version?

Not in the next twelve months. iOS Audiobookshelf listeners are already well served by Prologue, SoundLeaf, ShelfPlayer and AudioBooth. Meringo Listen is Android-first by deliberate choice.

Does it work with Android Auto?

Yes — bookshelf browse, search, and playback controls are wired through Android Auto, with chapter-aware transport. A double-press on a Bluetooth headset skips to the next chapter, not the next file.

How do I get it right now?

Meringo Listen is in closed testing ahead of its public launch (targeted for September 2026). To try it early, email support@meringo.app with the Google account email you'd use on the device, and Adam will add you to the test track.

Meringo Listen is on the Google Play Store — install it here. New listeners get a 14-day free trial of the full app, then a one-time $14.99 unlock.

Closed testing is open.

Meringo Listen reaches the Play Store this September. The closed-testing track is open now — install the real app, bring your own books or your Audiobookshelf server, and tell me what breaks.
