Prompt
Make a 0.4 s UI error sound effect for video at 30 fps. Output: one WAV, 48 kHz / 16-bit / stereo, exactly 19200 samples. Python + numpy/scipy only. Synthesise everything (no samples, no downloads). Fixed random seed. Sound: low muted thud + short dissonant interval, non-alarming, frame 0. Master: −14 LUFS integrated, true peak ≤ −1 dBTP. Verify length, loudness, peak with ffmpeg ebur128; render spectrogram; fix until checks pass.
