Sound effect synthesiser

Synthesises a sound effect with own code and returns a real WAV file: 16-bit mono PCM at 22050 Hz with a RIFF header. The wave shape is a square with a controllable duty cycle, a saw, a sine, a triangle or noise from a deterministic seeded generator. The envelope runs from attack to decay, the frequency can slide per second and swing with vibrato. Sample count, measured duration, peak, RMS, zero crossings and the first 16 samples are shown, and the file itself can be downloaded.
