About this build v0.2.14

What changed

  • Collections over 100 songs can now be filtered by album, playlist/setlist, and available audio stem.
  • Available-stem filtering is derived from actual song audio filenames instead of depending on optional chart difficulty metadata.
  • Numbered drum and vocal files are grouped into clear Drums and Vocals filter choices.
  • Album, playlist/setlist, and year were added as collection sort modes.
  • Search now includes playlist/setlist names and available stem labels.

Known limitations

Memory estimates are intentionally conservative and cannot guarantee that a browser will complete a large decode. Continuing past the warning may still close a memory-limited tab. Browser codec support remains format-dependent, and this build still decodes the selected song's stems fully into PCM memory.

Keyboard

Space plays or pauses. Home stops and returns to the beginning. Shortcuts are ignored while a control or text field has focus.

License notice

This build contains original HTML, CSS, and JavaScript with no bundled third-party runtime libraries, codecs, fonts, artwork, or songs. No project-wide open-source license has been selected yet. Users are responsible for having the right to use files they load.

LARGE DECODE WARNING

This song may exceed browser memory

Stem Hero must expand compressed stems into PCM for playback. Continuing may cause this tab to slow down or close on a memory-limited device.
