Change parameters to build an exact command. Your agent runs it with sb and gets the WAV.
Command
$ sb get AVVMR04KFC@1 --preset distress -o morse-beeps.wav
How it's made
Source
an electronic telegraph sidetone, a continuous 700 Hz sine keyed into dots and dashes.
Body
the fundamental dominates; a second harmonic at -54 to -44 dB models weak receiver distortion. Keyed band-limited receiver noise sits below -56 dB; there is no mechanical clack or room reverb.
Envelope
raised-cosine 5–14 ms key edges suppress wideband clicks; each mark sustains at constant gain. Dots last one unit, dashes three, intra-letter gaps one and inter-letter gaps three units.
Events
SOS uses 27 units at 105 ms, giving 2.835 s of code followed by a clean silent tail.
Variation
pitch, unit length and edge softness are physical controls; presets send SOS, CQ or 73. Pitch and timing never wander; rng only changes the very quiet receiver noise between renders.
