Usage

freq

Inside the app:

Command	Action	Example
/tune <frequency>	Join a frequency	/tune 104.5 or /tune flavortown
/nick <name>	Set your display name	/nick flavorpheus
/leave	Disconnect	/leave
Ctrl+R	Toggle audio streaming	Press Ctrl+R to start/stop
(Type anything else)	Send an encrypted message	Hello!

How it works

• You type a frequency. The client uses Argon2id to derive a 32-byte AES key from that string.
• The client connects to the relay server and joins a room identified by the SHA-256 hash of the AES key. The server never sees the frequency or the key.
• All messages and audio are encrypted with AES-256-GCM before leaving your machine.
• Audio uses real-time streaming — each ~100ms chunk is encrypted and sent individually. Multiple voices are mixed with numpy for overlapping audio.
• The server is a stateless blind relay. It broadcasts encrypted blobs to the room and stores nothing.

Security

Layer	Implementation
Key derivation	Argon2id (64 MiB, 3 iterations)
Encryption	AES-256-GCM with random 12-byte nonce
Room identity	SHA-256 of AES key (server never sees frequency)
Transport	WSS (TLS) to relay server
Identity	None. No accounts, no keys on disk, no persistent state.

Requirements

• Python 3.10+
• A microphone (for audio streaming)
• A terminal that supports 256 colors
