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.
| Parameter | Range | Default | Unit | Controls |
|---|---|---|---|---|
| pitch | 450 – 1100 | 700 | Hz | Sidetone pitch |
| unit | 0.075 – 0.14 | 0.105 | s | Dot duration |
| message | sos · cq · signoff | sos | — | Code message |
| edge | 0.005 – 0.014 | 0.008 | s | Key softness |
| receiver | 0 – 1 | 0.25 | — | Receiver colour |
| seed | int | 1 | — | Variation, reproducible |
The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
