Spinorama : a library to display speaker frequency response and similar graphs

This library provides an easy way to view, compare or analyse speakers data. This can help you take informed decision when buying a speaker instead of relying on commercial information or internet buzz. There are enough measurements now that you can do statistical analysis if you wanted too.

Jump to spinorama.org of all (1000+) speakers measurements.

Jump to the documentation to learn more about what it can do and how to use it.

Development setup

Prerequisites

Linux / macOS

./scripts/setup.sh

This installs system packages (via apt on Linux or brew on macOS), creates a Python virtual environment, installs all dependencies, downloads third-party assets, and compiles the Cython and Rust extensions.

Windows (PowerShell)

Install Python 3.12, Node.js and git manually, then run:

.\scripts\setup.ps1

The script automatically sets the PYTHONUTF8=1 environment variable (both for the current session and persistently for the user) so that Python reads files as UTF-8 by default. This is required on Windows where the system locale is typically not UTF-8. See Python on Windows UTF-8 mode for details.

If you prefer to set it yourself:

# Current session only
$env:PYTHONUTF8 = "1"

# Persistent (user-level)
[System.Environment]::SetEnvironmentVariable("PYTHONUTF8", "1", "User")
