# genpark-stft-spectrogram-mel-filterbank-skill

> genpark-stft-spectrogram-mel-filterbank-skill — alpha-park-genpark-stft-spectrogram-mel-filterbank-skill. Use this tool when you need to extract audio features from signals, solving problems like speech recognition, music classification, and acoustic analysis. It takes in audio signals and outputs log-energy features using Short-Time Fourier Transform (STFT), Hann windowing, and triangular Mel-filterbank. Apply this skill in contexts where audio signal processing and feature extraction are crucial, such as machine learning model training or audio data analysis.
