A GUI wrapper for testing and iterating on the aiosendspin server

Sendspin GUI

A GUI wrapper for testing and iterating on the aiosendspin server without needing to integrate with Music Assistant.

Features

• Server Management: Start/stop the Sendspin server with configurable settings
• Client Discovery: Automatic mDNS discovery of Sendspin clients on your network
• Group Management: Create and manage client groups for synchronized playback
• Audio Streaming: Stream audio files or test tones to groups
• Event Logging: Real-time event log with filtering capabilities

Installation

Prerequisites

• Python 3.12 or higher

Install with uv (recommended)

uv is a fast Python package installer.

# Install uv if you don't have it
pip install uv

# Install sendspin-gui
cd sendspin-gui
uv pip install -e .

# Or with dev dependencies
uv pip install -e ".[dev]"

Install with pip

cd sendspin-gui
pip install -e .

Usage

Run the GUI

# Using the installed command
sendspin-gui

# Or run as a module
python -m sendspin_gui

Quick Start

1. Start the server: Configure the server ID, name, and port, then click "Start Server"
2. Connect clients: Sendspin clients on your network will be discovered automatically (if mDNS is enabled)
3. Create groups: Select clients and click "Create Group" to group them for synchronized playback
4. Stream audio: Use the Stream panel to play test tones or audio files to your groups

• See client roles and group membership
• Select clients to create groups
• Disconnect individual clients

Groups Panel

• View all active groups
• Playback controls (play/stop)
• Volume control per group
• Expand groups to see and manage members

Stream Panel

• File: Browse and stream audio files (WAV, FLAC, MP3, etc.)
• Test Tone: Generate sine wave test tones at configurable frequencies
• URL: (Coming soon) Stream from network URLs

Event Log

Running in development

# Install in editable mode with dev dependencies
uv pip install -e ".[dev]"
# or: pip install -e ".[dev]"

# Run the app
python -m sendspin_gui

Code style

The project uses ruff for linting:

ruff check src/
ruff format src/

Architecture Notes

The GUI uses customtkinter for a modern appearance and runs the asyncio event loop in a separate thread to avoid blocking the UI. The AsyncBridge utility handles communication between the tkinter main thread and the async server operations.
