What you get

• 404 sounds (12.9 minutes) as WAV (44.1 kHz, 16-bit) and OGG; one-shots mono, loops stereo.
• Variations: 133 kinds of sound, most in 3-6 versions that really differ (pitch, length, layers), numbered so a game can pick one at random.
• 29 seamless loops (5.6 minutes): engines, beams, shield hums, alarms, hyperspace, reactor, computer rooms and four ship and planet ambiences. Built to repeat without a click; loop points in the WAV and OGG files, and every seam measured in loop_check.csv.
• Loudness-matched: one-shots at the same loudness, loops a little lower, peaks at most -1 dBFS.
• soundboard.html: hear every sound in your browser, offline; layer loops and mix them with sliders.
• Cue sheet (CSV + JSON): description, length, loudness and loop points of every file, and the random groups.
• A preview reel on this page plays every sound (12.4 minutes) with a timestamp list.

Checked by the build

No clipping, no silence at the start or end, no DC offset, every loop seam checked, no two files alike (a spectrum fingerprint over all of them), every OGG decoded and compared with its WAV, and the sound board tested in a browser.

What it does not include

No voices or spoken words, no music, no real-world gunshots.
