Sound
Send short messages between nearby devices.
Strong points
- No internet is needed for a nearby transfer.
Trade-offs
- Noise and device hardware can prevent a transfer.
- High-frequency sound may be audible to some people.
Choosing a sound mode
Try a short message with both devices close together.
| Sub-mode | Carrier | Throughput | Effective range | Audible? | Best for |
|---|---|---|---|---|---|
| Basic | Audible sound | Varies by message | Keep devices nearby | Audible | Short messages |
| Ultrasonic | High-frequency sound | Varies by message | Keep devices close together | May be audible to some people | Test device compatibility first |
Results depend on the devices, background noise and distance.
Get started
Two devices. One shared password. No intermediary.
Install Taftan on both devices, agree on the password through a separate channel beforehand, and run a quick test transfer using whichever channel fits your situation.
