This version contains a bugfix which makes Meyda work when installed via npm once again.
Published by jakubfiala almost 7 years ago
This version is an internal hotfix for our build system & dependencies, and should have no effect on the library itself, with the exception of it now actually working when installed via npm again 😄

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.
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
.

A major version release to cover API changes due to a bugfix (#157) and a change to underlying node APIs that causes output numbers to change. nodejs/help#456
There are no major API changes in this commit (other than those described above), but as output numbers may change, potentially causing issues relating to lookups based on data extracted and cached from a previous version of meyda. If you have a store of cached features, you may need to regenerate your data to maintain consistency with this version.
Also fixes a dependency issue with jsfft (pins to commit).
