Zoomed out, the wave left room above and below it, but the bright file,
the picked clip and its handles still took the whole height. And a click
in the wave beside the picked clip kept it picked, so only the strip
could take it back to the sound.
- fileReach in waveView.ts is how far up and down the file reaches:
full scale and its inset, never past the area. At level 1 it is the
whole height, zoomed in too.
- The bright file, the shade outside the clip and the two handles are
drawn within that reach.
- A click over the wave beside the picked clip picks the sound. Inside
the clip or on a handle nothing changes, and a drag still spans the
clip anew.
Tests:
- Unit wave-view: 11 green (1 new), a counter-check red
- e2e 34 (melektaus-atx): ALL PASSED, 91 checks (1 new)
- Gate (melektaus-atx): CHECK EXIT 0, 271 files, 4195 tests

The Sound tab always drew the wave at the full height of the tab. Quiet
stretches were hard to see, and there was no room above a loud wave.
- A level scale in dB stands left of the wave, a mark every 6 dB down
from 0, as long as a mark lies inside the area and at least 14 px
from the middle.
- The wheel over the scale zooms the height, from 0.25x to 16x. Over
the wave it zooms the time as before.
- What is louder than the area stops at its edge. The fade ramps grow
with the wave.
- Fit puts the height back to 1x. The tab keeps the height with its
view when another tab is shown.
- The rules live in waveView.ts (zoomLevel, levelMarks), the hooks
give the height, the scale and the top of a full-scale wave.
Tests:
- Unit wave-view: 10 green (2 new), 2 counter-checks each red
- e2e 34 (melektaus-atx): ALL PASSED, 87 checks (1 new)
- Gate (melektaus-atx): CHECK EXIT 0, 270 files, 4183 tests

A sound asset now opens in a tab that shows its file as a waveform.
Two handles set where the sound starts and ends in the file, and that
stretch is the sample: Play sound, a song item and an instrument's
Sample all play it and nothing else. The file itself is never changed.
- The asset has three new rows: Start (s), End (s) and Edge fade (ms).
End 0 is the end of the file, the fade is 10 ms by default. Older
assets have no values and play the whole file as before.
- Every way of playing asks playedSoundOf() for a name instead of the
file: the file, or <file>#<start>~<end>~<fade> for a cut.
- SoundLibrary makes the cut from the decoded file the first time that
name plays and ramps each edge inside the file over the fade. Length
and peaks of a cut are read from the file without a copy.
- Cut buffers can be made again at any time, so the library lets the
oldest go past 64 Mi samples. A voice holds its buffers itself.
- The tab draws min/max per pixel from 256-sample block peaks, and the
samples as a line when zoomed in far. Wheel zooms, the middle button
pans, as in the music tabs. Wave, cut and ruler sit under a mask,
so a handle panned out of view does not draw over the panels beside.
- Dragging a handle moves that edge, dragging elsewhere spans a new
stretch. One drag is one undo step for both edges. Whole file puts
the handles back, Play or Space plays the stretch with a playhead.
- The inspector preview and the Sound FX preview play the cut too, and
the song lanes draw and repeat it.
Tests:
- Unit: sounds 20, wave-view 8 (new), sound-library 68, plus 258 in
the touched areas (instrument, song, pattern, inspector, tabs)
- e2e 34 on melektaus-atx: ALL PASSED, 57 checks (7 new)
- Gate on melektaus-atx: CHECK EXIT 0, 253 files, 3936 tests
