practically universal music pre-processor pumpp up the jams The goal of this package is to make it easy to convert pairs of (audio, jams) into data that can be easily consumed by statistical algorithms. Some desired features: Converting tags to sparse encoding vectors Sampling (start, end, label) to frame-level annotations at a specific frame rate Extracting input features (eg, Mel spectra or CQT) from audio Converting between annotation spaces for a given task
