Acid Synth

A simple acid synthesizer built with Python and PySide6.

Features

• Real-time audio synthesis: Play notes with your computer keyboard.
• ADSR Envelope: Control the Attack, Decay, Sustain, and Release of the sound.
• Oscillator Mix: Blend between sine and sawtooth waveforms.
• Low-pass Filter: Shape the sound with cutoff and resonance controls.
• Effects: Add Delay, Reverb, and Chorus to your sound.
• Oscilloscope: Visualize the waveform in real-time.

Requirements

• Python 3.13 (64-bit)
• Microsoft C++ Build Tools (for sounddevice compilation, if necessary)

Installation

1. Clone the repository:

   git clone https://github.com/your-username/acid-synth.git
   cd acid-synth

2. Create and activate a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows, use `venv\Scripts\activate`

3. Install the dependencies:

   pip install -r requirements.txt

Usage

Run the application with the following command:

python synth.py

Controls

• Keyboard: The keys Z through / on your keyboard are mapped to musical notes.
• Shift + Key: Increase the note velocity for a louder sound.
• Knobs: Use your mouse to turn the knobs and adjust the synthesis parameters.
• Esc: Close the application.

Troubleshooting

• No sound when pressing keys: Make sure the application window is focused. Click on it if necessary.
• output underflow in the console: The latency and blocksize in synth.py have been adjusted to common values that should prevent this. If you still experience issues, you can try increasing the blocksize further.
• Issues with package installation: Ensure you have activated the virtual environment and that pip is up to date (pip install --upgrade pip).
