Abstract

The fast growth of the popularity of digital communication and multimedia applications raises new requirements to audio quality in such tasks as online education, virtual conferences, podcasting, and media content generation. Nevertheless, the quality of audio recording in real-life conditions often suffers from noise, echoes, reverberation, and other types of interference, reducing both speech intelligibility and the listening experience. Therefore, this paper presents the concept of the EchoFree AI-based audio enhancement software solution to deal with the described problem. The solution is based on the combination of a trained speech enhancement neural network with the custom autoencoder in order to find the best balance between noise filtering and preserving speech signal properties. The suggested system is operating in the time-frequency domain using the technique of the Short-Time Fourier Transform (STFT) in feature extraction and implements a pipeline comprising four major stages: preprocessing, analysis of the spectrogram, audio enhancement based on the model and inverse STFT for the signal reconstruction. Moreover, EchoFree is developed as a fully functional web-based application allowing the user to upload, enhance, and download audio files. Finally, experimental analysis showed that EchoFree significantly outperforms classical techniques and speech enhancement models used separately.

Full Article/Conclusion

This paper presented EchoFree, an AI-powered audio enhancement system designed to improve the quality of pre-recorded audio by effectively reducing noise while preserving speech clarity and naturalness. The proposed system utilizes a hybrid deep learning approach that combines a pretrained speech enhancement model with a custom autoencoder, enabling efficient noise suppression and accurate reconstruction of clean speech signals. By operating in the time-frequency domain using Short-Time Fourier Transform (STFT), the system is able to capture important audio features and perform effective separation of speech and noise components. The experimental results demonstrate that EchoFree significantly improves speech intelligibility, perceptual quality, and overall audio clarity across various noise conditions such as background noise, echo, and environmental disturbances. The system achieves better performance compared to traditional signal processing techniques and single-model approaches, providing more stable and consistent results. Additionally, the modular design and web- based implementation make the system scalable, user-friendly, and suitable for real-world applications.   Overall, EchoFree provides a robust, efficient, and practical solution for audio enhancement, contributing to the advancement of intelligent speech processing systems. The proposed approach highlights the effectiveness of combining signal processing with deep learning techniques to address real-world challenges in speech enhancement.
