Some of you may remember an earlier post here where I was looking for testers for liquidWave — my attempt at getting Plexamp's sonic-analysis experience onto a self-hosted Emby setup. There's been a lot of development since, and it's now on the Google Play Store in closed testing. I'm looking for testers again.
What it does: a small backend you run yourself listens to your library once and learns what each track sounds like — not genre tags — then powers auto-curated Sonic Mixes, Track Radio/Similar, Sonic Adventure (a generated journey that morphs from one track to another), and an Artist Mix Creator.
It's also just a solid Emby player: crossfade that trims silence instead of blending dead air, 10-band EQ, offline downloads with proper resume, Android Auto, Cast, a widget, and a web app if you're not on Android.
Audiobooks are a first-class citizen, not an afterthought — chapter-aware browsing and resume (it picks up at the right chapter and position, not just the start of a file), variable playback speed, and a sleep timer. They download for offline listening too, and still resume in the right place when you come back.
Privacy: fully self-hosted — no account, no cloud, no ads, no telemetry, nothing leaves your network. Needs Emby 4.8+. The app alone is a full Emby player in ~5 min; the sonic features need the small analysis service too.
Joining the test takes two steps (Play's closed testing works via a Google Group):
- Join: https://groups.google.com/g/liquidwave-testers
- Then https://play.google.com/apps/testing/guru.liquid.embysonic → "Become a tester"
Then it installs from Play normally. If you can, joining via Play rather than sideloading really helps — Google requires 12 Play testers for 14 continuous days before it can go public.

Actively developed and definitely still beta, so expect the odd rough edge — bug reports and ideas genuinely welcome, happy to answer anything in the comments.
