# NoiceSynth Linux Emulator

This folder contains a Linux-based prototype for the NoiceSynth engine. It allows you to develop and visualize the DSP code on a desktop computer before deploying it to the RP2040 hardware.

## Architecture

*   **Engine (`synth_engine.cpp`):** The exact same C++ code used on the microcontroller. It uses fixed-point math (or integer-based phase accumulation) to generate audio.
*   **Host (`main.cpp`):** A Linux wrapper that uses:
    *   **Miniaudio:** For cross-platform audio output.
    *   **SDL2:** For real-time oscilloscope visualization.

## Quick Start (Distrobox)

If you don't want to install dependencies manually, use the included script. It creates a lightweight container, installs the tools, and compiles the project.

1.  Ensure you have `distrobox` and a container engine (Docker or Podman) installed.
2.  Run the build script:
    ```bash
    ./compile_with_distrobox.sh
    ```
3.  Run the synthesizer:
    ```bash
    ./noicesynth_linux
    ```

## Manual Build

If you prefer to build directly on your host machine:

1.  **Install Dependencies:**
    *   **Debian/Ubuntu:** `sudo apt install build-essential libsdl2-dev wget`
    *   **Fedora:** `sudo dnf install gcc-c++ SDL2-devel wget`
    *   **Arch:** `sudo pacman -S base-devel sdl2 wget`

2.  **Download Miniaudio:**
    ```bash
    wget https://raw.githubusercontent.com/mackron/miniaudio/master/miniaudio.h
    ```

3.  **Compile:**
    ```bash
    make
    ```
