Description

This release brings two very exciting additions to Meyda, both contributed by the amazing @odub

🎉 chroma 🎉

we've been wanting to add this for a while! Chroma is a very common audio feature which calculates the spectral energy of the signal for each chromatic pitch class (C, C♯, D, D♯, E, F, F♯, G, G♯, A, A♯, B). Often used to analyse the harmonic content of recorded music, such as in chord or key detection.

Hop size

This optional global parameter determines the number of samples between the starts of consecutive frames. Setting it to less than bufferSize causes frames to overlap, meaning that the feature will change more smoothly over time. Defaults to the value of bufferSize.
