aiovban 1.0.2

An asyncio VBAN implementation

aiovban

An ergonomic, asyncio-first Python wrapper around the VBAN protocol.

Overview

aiovban provides a modern interface for interacting with the VBAN protocol, commonly used with VoiceMeeter. It leverages Python's asyncio for high-performance, non-blocking I/O and dataclasses for clean, typed data structures.

Features

• Full Protocol Support: VBAN Audio, Text (Command), Service (Ping/RT), and Serial.
• Asyncio Native: Built from the ground up for asynchronous applications.
• VoiceMeeter Abstraction: High-level VoicemeeterRemote API for intuitive control of strips, buses, and engine commands.
• Interactive TUI: Includes aiovban-tui, a full-featured terminal mixer for remote VoiceMeeter control.
• Type Safety: Extensively typed using Python dataclasses and enums.

Installation

pip install aiovban

Usage

High-Level VoiceMeeter Control (Recommended)

The VoicemeeterRemote class provides the easiest way to control a remote VoiceMeeter instance.

import asyncio
from aiovban.asyncio import AsyncVBANClient, VoicemeeterRemote

async def main():
    client = AsyncVBANClient()
    await client.listen("0.0.0.0", 6980)

    # Register a remote VoiceMeeter device
    device = await client.register_device("192.168.1.50")
    
    # Initialize the high-level remote
    vm = VoicemeeterRemote(device)

    # Toggle mute on the first strip
    await vm.strips[0].set_mute(True)
    
    # Set gain on the first bus
    await vm.buses[0].set_gain(-10.5)
    
    # Restart the audio engine
    await vm.restart()

asyncio.run(main())

Low-Level Protocol Usage

For applications requiring direct stream access, you can interact with the client and streams directly.

Sending Commands via Text Streams

# Create a text stream for outgoing commands
command_stream = await device.text_stream('Command1')
await command_stream.send_text('Strip[0].Mute = 1;')

Receiving RT Packets (Real-time State)

from aiovban.asyncio.util import BackPressureStrategy

# Subscribe to RT updates (30 times per second)
rt_stream = await device.rt_stream(30, back_pressure_strategy=BackPressureStrategy.DRAIN_OLDEST)

# Get the next incoming packet
packet = await rt_stream.get_packet()
print(f"Master Gain: {packet.body.buses[0].gain}")

Manual Packet Construction

from aiovban.packet import VBANPacket
from aiovban.packet.headers.audio import VBANAudioHeader
from aiovban.enums import VBANSampleRate

# Construct a custom VBAN audio header
header = VBANAudioHeader(
    sample_rate=VBANSampleRate.RATE_44100, 
    channels=2, 
    samples_per_frame=256,
    streamname="Stream1"
)

# Wrap in a packet
packet = VBANPacket(header=header, body=b'\x00' * 1024)
packed_bytes = packet.pack()

Interactive TUI

aiovban comes with a powerful terminal-based mixer. You can launch it directly from your terminal:

aiovban-tui --register 192.168.1.50

Note: Click on strip titles to rename them.
