I got fed up with Android resampling on my M21, so I built a bit-perfect player using the FiiO SDK

Hey guys. I’ve been an audio hobbyist for about 20 years now, and I finally hit my limit trying to get my local hi-res library to play properly without Android's AudioFlinger resampling or truncating everything.

I spent the last few months building a dedicated player called Meringo. I’ve been doing all the dev work directly on my FiiO M21, heavily utilizing the FiiO SDK for direct-to-DAC routing so the audio path stays totally clean. I even built a format strip into the UI that throws an amber warning if Android tries to touch the signal. Beyond that, it has a 32-bit float biquad PEQ chain with AutoEQ CSV support (so you can load Squiglink profiles easily), and it runs local files alongside a Jellyfin server.

I've mostly been testing it with my M21 paired with my FT1s and ZiiGaat Horizon tribrids, but I need to see how the engine handles other FiiO gear.

But I'm a solo dev with a new account, so I'm stuck in the classic Google Play "20-tester jail." I literally just need 20 people to opt-in for closed testing so I can get this published. I'm not selling anything. I just need this app to actually see the light of day.

If anyone is down to kick the tires and help me out, the links are below. Let me know if you run into any weird bugs.

*UPDATE — v1.7.5 is in the test track*

Thanks to everyone who reported issues. This build addresses:

  • Missing library tracks — scanner now uses a MIME + file-extension hybrid check. If your storage provider was reporting audio files as... well wrong (common on some SD card configurations), Meringo now recognises them by extension instead of skipping them. If you were seeing ~1,165 tracks instead of your full library, try a rescan after updating.
  • Jellyfin trap — there's now a "Use local files only" link on the connection screen so you're never stuck
  • ANR during USB DAC hot-plug — fixed
  • Startup crash on certain devices — fixed

DM me if you'd like to join the test track.

Hey all,

I’ve been building a music library for about 25 years now. When I was a kid, I would spend hours on the floor reading every word in the liner notes, and now as an adult I’m sitting on 500GB+ of FLAC files.

In my day job, I’m an implementation lead, so I’m naturally obsessive about making sure complex systems actually talk to each other and work in the real world. I finally reached a breaking point with the current state of Android music players on dedicated hardware. Most of them feel like they were designed for streaming discovery first, leaving local collections as a second-class citizen. They’re bloated, cluttered, and the UI usually feels like an afterthought on a high-end DAP screen.

So I built Meringo.

I’ve been optimizing the engine and what I call the “Deep Velvet UI” specifically on my FiiO M21. I wanted the software to feel as premium as the hardware we’re actually holding.

A few things I baked in because I needed them for my own gear:

A/B Laboratory: A gapless comparison tool with auto-gain compensation. I was tired of being fooled by "louder is better" bias when testing filters or EQ.

Surgical PEQ: 10-band, but with axis-lock gestures so you don't accidentally slip your frequency setting while trying to tweak gain on a small screen.

The Tuning Vault: Native support for importing AutoEQ CSV/JSON profiles from Squiglink.

Coffee-Themed Moods: Genre tags are a mess for me, so I organized my smart playlists by "roast" (Lite/Fruity vs. Dark/Bold).

The Hurdle:

Google’s new dev rules require a bunch of closed testers to stay opted-in for 14 days before I can go live on the Play Store. If you're a fellow local-file curator and want to help a solo dev get past the gate, I’d love to have you kick the tires on the alpha.

A quick heads-up: This is a side project I’m doing in my off-hours, so please bear with me if it takes a minute to get back to you. I’m looking for brutally critical feedback—if something feels clunky or doesn't make sense on your specific hardware, please tell me.

I’ve attached some shots of the UI. If you’re interested, drop a comment or DM me and I’ll send some info / add you to the Google Play list. I would love to launch this soon :-D

Cheers,

Adam

UPDATE: I’m honestly blown away by the response here. We’ve got 6 people in the alpha group so far, but I’m still looking for another 15–20 to clear that Google Play "tester" hurdle.
