How to Use

Controls

• Tap the screen to show/hide controls
• Add some audio files (access the playlist via the bottom dropdown) Screen grab: Sliders
• Select animations from the top dropdown Screen grab: Sliders

Sliders

• Ajust sliders to change how the animation reacts to the music (each animation will remember its settings) Screen grab: Sliders
• Pay close attention to the top slider, it adjusts stability (smooth animation) vs responsiveness (matching the music) Screen grab: Sliders
• Some sliders have an 'auto' icon, tapping it disables the slider and makes that control automatically match energy of the music Screen grab: Sliders

Memory Slots

• The numbers [1] to [5] above the sliders are memory slots
• Each animation has 5 memory slots to save your favourite settings
• Memory slots can be copied: long press a slot until it turns pink, then drag it over another slot Screen grab: Sliders

Special build instructions for ARM64 Linux

flutter_soloud on Linux ARM64

1. Install system audio libraries:

bash

sudo apt install libasound2-dev libflac-dev libopus-dev libogg-dev libvorbis-dev

2. Run with system libraries flag:

The bundled libraries in flutter_soloud are x86_64 only. TRY_SYSTEM_LIBS_FIRST=1 tells it to use system libraries instead.

TRY_SYSTEM_LIBS_FIRST=1 flutter run -d linux

OR FOR PROJECT-PERMANENT FIX

# linux/CMakeLists.txt
# Add at top of file
set(ENV{TRY_SYSTEM_LIBS_FIRST} 1)

That way it's in the project itself, works on any machine, and flutter run just works.

linux/CMakeLists.txt is part of your project and lives in your repo. Flutter generates it once when you first create the project and never touches it again.
