Pure Synth Sci-Fi - 250 Space and Tech Sound Effects

No AI: every sound in this pack was computed by our own synthesis code, written in Python. No AI, no samples and no recordings went into it. The zip includes a PROVENANCE.md that lists the method and every tool.

250 sci-fi sound effects for space shooters and tech games: laser and plasma weapons, energy impacts and explosions, computer beeps and scanners, alarms, ship engines and warp jumps, airlocks and doors, shields, teleports, robots and glitches.
