A foobar2000 component that lets you override the length of any track, hide individual subsongs from the Media Library, and read playback time at millisecond precision.

Language: English | 中文

Features:

Duration Manager — custom track length

• Set a custom length for any track via the context menu “Set custom duration”.
• Manage all overrides in Preferences → Tools → Duration & Subsong Manager → Duration Manager (search, edit, delete).
• Overrides are matched by file content hash + subsong index, so they survive file moves/renames.
• During playback the track is automatically truncated to the custom length (jumps to the next track when reached).

Subsong Manager — hide subsongs

• For multi-subsong files, choose exactly which subsongs are visible in the autoplaylists.
• Configure include/exclude ranges (e.g. 1-3,5,7) or checkbox in Preferences → Tools → Duration & Subsong Manager → Subsong Manager.
• Note: this filters the Media Library query at runtime, so changes take effect after a restart.

High-Precision Timer (UI element)

• An auxiliary UI element for the Duration Manager that shows playback position and track length in millisecond precision: [HH:]MM:SS.mmm.
• Add it via the layout editor like any other UI element (“High-Precision Timer”).

Compatibility

• foobar2000 v2.0 or newer, Windows, 32-bit and 64-bit.
• Built against the foobar2000 SDK (2025-03-07).
