Checking whether the notes line up meant packaging the song, finding it in
the game and starting it there. The review panel now plays the song folder
itself: a transport above the lyrics, the line being sung highlighted, words
lighting up as they are reached, and a playhead sweeping each line against
its notes. Clicking a line or a word plays from there.
Playback is modelled on the game rather than on whatever is convenient: #MP3
is the audio and the clock, #VIDEO is muted background slaved to it, and the
times are the same seconds the notes were generated from. A word that lights
up late here is late in the game.
package now strips the audio track from the video it writes. It is the same
recording as the #MP3, so a player that does not mute the video plays both a
few frames apart, which is heard as an echo. The compatible-video branch
remuxes with -c copy -an rather than copying the file, so it still does not
re-encode. The browser player mutes the video as well, which covers song
folders built before this.
A new /api/jobs/{id}/media/{audio,video,cover} serves what the song's own
#MP3/#VIDEO/#COVER headers name, refusing anything resolving outside the song
folder. Range requests come from FileResponse, so seeking works.
Also, per review: CREATE SONG moves out of the form and into the top of the
queue, where it is always available, and a successful submission keeps the
fields it sent instead of emptying them.
Replace arbitrary demo pitches with the actual melody transcribed from
Gilbert DeBenedetti's public-domain "Level 4, Flowing" arrangement (E
minor, 6/8), converted to UltraStar semitones, with one note per word
across both demo lines.
The review panel used to show a full line of packed text with one
undifferentiated strip of notes below it, so it was impossible to tell
which notes belonged to which word. The forced-alignment stage already
produces per-word timestamps in alignment.json, but they were never
surfaced past the pipeline.
/api/jobs/{id}/review now includes each line's per-word timing, and the
frontend spaces words out by their real sung timing (karaoke-style)
instead of normal text flow, with the note strip sharing that same time
axis so each note lands directly under its word. Alternating lane
backgrounds make the word/note pairing unambiguous. Dropped lines and
jobs without alignment data keep the old plain-text rendering.
