NeuralBeat 1.0.0

NeuralBeat 1.0.0 - "The Isochronic Update"

This major release introduces Isochronic Tones support along with UI enhancements and preset restructuring.

---

✨ New Features

• Isochronic Tones: A completely new beat type that generates rhythmic pulsing tones.

  • Single tone (carrier) pulsed on/off at the brainwave frequency
  • Works with both headphones and speakers (no stereo separation required)
  • Pulse rate controls the brainwave entrainment frequency
  • Carrier tone is the audible pitch you hear

• Dynamic UI Labels: When Isochronic mode is selected, the frequency labels change to "Pulse Rate (Hz)" and "Carrier Tone (Hz)" for clarity

• Restructured Presets: Presets are now organized into two categories:

  • "Binaural Beat / Monaural Beat" - Combined for easier navigation
  • "Isochronic Tone" - New section for isochronic presets

---

🎨 UI & UX Improvements

• Three Beat Modes: Users can now select between Binaural Beat, Monaural Beat, and Isochronic Tone
• Dynamic Box Names: The Left/Right frequency boxes now change labels based on the selected beat type
• Centered Layout: Beat Type, Background Noise, and Ramp Settings sections are now centered for better alignment
• Merged Preset Categories: Binaural and Monaural presets are now combined into one column
• Updated Preset Type Dropdown: Create Preset dropdown now shows "Binaural Beat / Monaural Beat" and "Isochronic Tone"

NeuralBeat 0.9.0

NeuralBeat 0.9.0 - "The Visualizer Update"

This is a major feature release that introduces a host of new audio capabilities and significant user interface enhancements, centered around the new real-time oscilloscope.

---

✨ New Features

• Real-time Oscilloscope: A new, pop-out oscilloscope window provides a live visualization of the generated audio waveforms.
  • Scrolling Display: Features a smooth, scrolling display for seamless animation.
  • Customizable Colors: Choose from multiple color palettes for the left and right channel lines via the Settings menu.
  • Merged/Split View: A "Merge Waves" toggle allows you to either overlay the waveforms for phase comparison or split them into separate halves of the display for clarity.
• Background Noise Generator: You can now mix in background noise with your beats to help mask distractions.
  • Available types: White, Pink, and Brown noise.
  • Includes a dedicated volume control.
• Triangle Waveform: A new Triangle waveform has been added to the list of available oscillators, providing another tonal option.
• WAV Export with Progress: The WAV export functionality now runs in a background thread and displays a progress bar, preventing the UI from freezing during long exports.

---

🎨 UI & UX Improvements

• Major UI Reorganization: The main window has been restructured for better clarity.
  • A new "Advanced Controls" section now neatly houses the noise and ramp settings.
  • These settings are further organized into distinct "Background Noise" and "Ramp Settings" subsections.
• Modern Toggle Switch: The "Enable Ramp" checkbox has been upgraded to a modern, stoggle switch for better visual feedback.
• Relocated Status Bar: The real-time status display (Beat, L/R Hz, Time Remaining) has been moved to the bottom control bar, placing it centrally between the "Generate" and "Stop" buttons for maximum visibility.
• Streamlined Ramp Controls: The "Brainwave Presets" dropdown (Alpha, Beta, etc.) has been removed from the ramp settings to simplify the interface.
• Layout Centering: The "Advanced Controls" subsections are now centered within their container for a more balanced and professional look.

---

🐛 Bug Fixes

• Fixed a critical bug where the oscilloscope window could not be closed using the window's 'X' button.
• Resolved an issue where the oscilloscope would not draw any data after being opened.
• Fixed a NameError crash that occurred due to the UI update loop being called before the status variable was initialized.
• Corrected an AttributeError related to ttkbootstrap.Switch by using the compatible ttk.Checkbutton with a round-toggle style.
• Fixed an issue where identical left and right channel waveforms would merge and become indistinguishable in the oscilloscope; they are now visually separated by default.

---

🔧 For Developers & Contributors

• Project Renamed: The project has been officially renamed from "BinauralBeatGenerator" to "NeuralBeat". All internal paths, configuration directories (~/.neuralbeat), and documentation have been updated accordingly.
• Exhaustive Documentation: The README.md has been completely rewritten to provide comprehensive details on all features, a full user guide, and in-depth information on the project's architecture and scientific principles.
