Audio-Watermarking-MATLAB-Project

Watermark Audio and Image GUI is a MATLAB-based graphical user interface that allows users to apply watermarks to audio files using image data.

Watermark Audio and Image GUI

This is a MATLAB GUI application that allows users to upload an audio file and an image, apply a watermark to the audio using the image data, and then visualize and play both the original and watermarked audio. The app also provides functionalities to display the grayscale version of the image and its histogram.

Features

• Upload Audio: Upload an audio file (WAV format) and visualize its waveform.
• Upload Image: Upload an image file (PNG, JPG, JPEG, BMP, GIF) and visualize the grayscale version and its histogram.
• Watermark Strength (WMS): Adjust the watermark strength using a slider.
• Play Original Audio: Play the original audio.
• Play Watermarked Audio: Play the audio after watermarking.
• Apply Watermark: Apply watermarking to the audio using the grayscale image and visualize the modified audio waveform.
• Grayscale Plot: View a line plot of the grayscale version of the image.
• Histogram: View the histogram of the grayscale image.

Requirements

• MATLAB 2019b or higher
• Audio and Image Processing Toolbox (for audio and image manipulation)
