Application Overview:

The "Live" Autotune application applies an autotune effect to audio files, correcting their pitch to align with a specified musical scale. It features a graphical user interface (GUI) for easy interaction and provides visual feedback through spectrum plots of the original and autotuned audio.

How to Use the Application:

1. Launch the Application:

  * Locate and run the executable file (e.g., 'AutotuneApp.exe'). A window titled "Simple Autotune GUI with Spectrum" will appear.

2. Select an Audio File:

  * Click the "Select Audio File" button.

  * A file dialog will open. Navigate to the desired '.wav' audio file and select it.

  * A message box will confirm the selected file's name.

3. Enter the Autotune Key:

  * In the "Enter autotune key (e.g. C:maj, A:min):" field, type the desired musical key for autotuning.

  * **Examples of valid formats:**

  * 'C:maj' (C Major)

  * 'A:min' (A Minor)

  * The field defaults to "C:maj".

4. Run Autotune:

  * Once an audio file is selected and a key is entered, click the "Run Autotune" button.

  * The "Run Autotune" button will be disabled during processing, and a progress bar will update to show the autotuning's progress.

5. Processing and Playback:

  * The application will load the audio, perform pitch detection, apply pitch correction based on the selected key, and re-synthesize the audio.

  * Upon completion, a success message will appear, indicating the processing time, and the autotuned audio will automatically begin playing.

  * The application will wait for the playback to finish.

6. View Spectrum Analysis:

  * After the autotuning process and playback are complete, two plots will be displayed in the GUI:

  * "Original Audio Spectrum": Shows the frequency spectrum of the input audio file.

  * "Autotuned Audio Spectrum": Displays the frequency spectrum of the processed, autotuned audio, allowing for a visual comparison of the effect.

7. Reset for New Operation:

  * After the process is finished, the "Run Autotune" button will be re-enabled, and the progress bar will reset, allowing you to select a new file or key and run the autotune again.

Important Notes:

===============================

  * This application is designed as an offline processing tool due to the computational demands of high-fidelity audio manipulation. It does not perform real-time autotuning.

  * The application is a standalone executable and does not require Python to be installed on your system to run.
