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

> genpark-stft-spectrogram-mel-filterbank-skill — alphaparkinc-genpark-stft-spectrogram-mel-filterbank-skill. Use this tool when you need to extract audio features from signals, solving problems like speech recognition, music analysis, and acoustic event detection. 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 classification tasks.
