Cache

Manage cached waveform data used for timeline display. Plinken caches pre-computed waveform LODs (levels of detail) to keep timeline scrolling and zooming smooth.

Open from Settings > Cache (keyboard shortcut: Cmd+, then select the Cache tab).

Settings

Setting	Type	Editable	Description
Waveform Cache	path	No	Location of cached waveform LOD data (read-only)
Free Cache	button	—	Delete cached waveforms for all projects except the current one

Waveform Cache Path

The cache path is shown as a read-only field. By default, the cache directory is located at:

~/Documents/Plinken/.cache/

Each project’s cache is stored in a subfolder named after the project. The cache directory is safe to delete — Plinken will regenerate waveform data as needed.

Free Cache

Click Free Cache to delete waveform caches for all projects except the currently open project. This is useful for reclaiming disk space after working on many projects.

The button scans the cache directory and removes subdirectories for projects other than the active one. The current project’s cache is always preserved so you don’t experience any performance degradation.

What Gets Deleted

Pre-computed waveform LODs for inactive projects
Thumbnail cache data for inactive projects

What Is Preserved

The current project’s waveform cache
The cache directory itself

Lua API

-- Get the cache path
local path = pl.cmd("settings:get", { key = "cache.path" })

-- Get max cache size in MB
local max_mb = pl.cmd("settings:get", { key = "cache.max_size_mb" })

-- Set max cache size to 2 GB
pl.cmd("settings:set", { key = "cache.max_size_mb", value = "2048" })
