Librosa
Librosa is a Python library for audio and music analysis, providing tools to extract features like tempo, pitch, and spectral characteristics from audio files. It is widely used in music information retrieval (MIR), speech processing, and machine learning applications involving audio data. The library simplifies tasks such as loading audio, computing spectrograms, and detecting beats or notes.
Developers should learn Librosa when working on projects that require audio signal processing, such as music recommendation systems, speech recognition, or sound classification in machine learning. It is particularly useful for extracting meaningful features from audio for use in models, analyzing music structure, or building audio-based applications in Python.
