Out of the way

Lives in your menu bar (macOS) or system tray (Windows / Linux). Never in your dock or taskbar. One click away when you want it, invisible the rest of the time.

Pop-out visualizer

A dedicated visualizer window with the full MilkDrop engine. Hundreds of reactive presets running natively in Metal, Direct3D, or OpenGL. Drag it to a second monitor, go full-screen, leave it running.

Plays everything

FLAC, ALAC, MP3, AAC, Ogg, Opus, WAV, AIFF, up to 24-bit / 384 kHz studio masters. Bit-perfect to whatever DAC you've got.

surround_sound

Native 5.1 / 7.1

Live albums, DJ sets, classical movements. No click, no silence, no pause between tracks. The way they were mastered.

SweetFades

Album-aware crossfades with loudness leveling baked in. Songs flow at matched volume. Nothing jumps out, nothing falls away.

hub

Multi-room sync

Cast the same audio to other Caldera devices on your network, sample-accurate. Not AirPlay. Own-tech mesh that just works.

10-band parametric EQ

Dial in your room's curve once, applied across every track, sample-rate, and channel layout. No re-tuning per source.

Smart caching

Upcoming tracks prefetch silently in the background. Replays never touch the network. Even tricky containers start instantly.

Self-updating

New versions install themselves in the background, without interrupting playback. No package manager, no reboot, no thinking about it.
