Drift // Audio

Ambient sound mixer for sleep and focus on long nights and long flights
New in version 0.2.2
Fixes user-saved presets, which were missing from the 0.2.1 build: save your current mix, volumes, and per-layer settings as a named preset, then recall it anytime.

Known issue: playback can still stop after a while, especially with the screen off (this affects all sounds). It is a limitation of the current audio engine. A full rebuild onto a native engine is in progress and will be the focus of the next major update, fixing this for good.
Drift is an ambient soundscape mixer. Layer nature recordings and synthesised drones at independent volumes, mix freely across two categories, and let the sleep timer fade things out when you're done. Everything runs offline.

Sound categories:

* Planetside — rain, fire, water, wind, birds, crickets, and other nature sounds.
* Deep Space — synthesised drones and recorded engine and hull textures.

Features:

* Mix any number of sound layers at independent volumes
* Built-in presets for quick atmospheres
* Sleep timer with 15, 30, 60, and 90 minute options
* Background playback with lock-screen media controls
* Fully offline — no network access required after install
* No ads, no tracking, no account
