v3.3.0 — A sound on save, every app's audio, and bulk delete

Clipper now tells you a replay was saved without you looking away from the game, records the sound of every app on every output, and can delete clips in bulk.

A sound when a replay is saved

Press the replay hotkey and you hear a short chime once the clip is written, about a twentieth of a
second later. That's the one confirmation that reaches you mid-game, and hearing it means the file
exists, not just that the key was pressed. It's on by default. Settings → Replay & recording has the
switch and three sounds to choose from:

• Chime: two bell notes rising, over in about a second. The default.
• Pop: one soft note that slides into place. The shortest, and the easiest to miss under a busy game.
• Sparkle: a quick four-note run. The most celebratory, and the easiest to pick out over loud audio.

All three are mastered to the same loudness, a little under typical game audio, so switching sounds
changes the character, not the volume. Choosing one plays it.

Desktop audio: every app, every output, and never Clipper

Desktop audio used to record one device's mix, whichever output was the default when the recorder
started. That caused three problems:

• Switching outputs silenced your clips. Moving from speakers to a headset left the recorder on
  the speakers, recording nothing, until you restarted it.
• Audio sent to another output was missing. Voice chat on your headset while the game plays on
  your speakers came out without the call.
• Clipper's own sounds got in. The new save chime would have ended up in the next replay, and so
  would a clip you previewed in the grid.

Now the recorder asks Windows for the sound of every app except Clipper, on every output, and
all three problems are gone. Switch your default device mid-game and the recording doesn't notice.
Measured against the old way, it uses the same CPU (about 0.2% of one core), and the sound lines up
with the picture within 6 ms of where it used to.

On Windows older than 10 version 2004, which can't record per app, Clipper falls back to the old
way, with one improvement: it now follows your default output when you switch devices, keeping the
buffer. The desktop audio setting says which of the two is running.

Device changes are also handled on a thread of their own now, so switching outputs never costs a
frame of video. Before, it could drop a couple.

Delete several clips at once

A card's ⋮ menu → Select puts a checkbox on every card. Click anywhere on a card to tick it
(the box, the picture or the info row), or use Select all for everything in the category you're
looking at. The bar at the top shows how many clips you've ticked and how much space they take, and
Delete removes them all after one confirmation. Cancel or Esc backs out.

Deleted clips don't go to the Recycle Bin, the same as deleting one at a time.
