Apply envelope & panning after biquad filtering. This may fix the weird popping problem. It also reduces the number of operations that are done "in stereo", so it could help performance. It also fixes a previously unnoticed problem where a ring-modulated waveform had 2x the amplitude of an un-modulated waveform. The test differences look large but it's because some values got changed in the LSB after the mathematical divisions were moved around.

This package contains the "stubs", or type definitions for CircuitPython. With some advanced editors and other tools, this information can be identify TypeErrors, AttributeErrors, and other problems before you deploy your code to a device and can even help autocomplete your code. .. |Build Status| image:: https://github.com/adafruit/circuitpython/workflows/Build%20CI/badge.svg :target: https://github.com/adafruit/circuitpython/actions?query=branch%3Amain .. |Doc Status| image:: https://readthedocs.org/projects/circuitpython/badge/?version=latest :target: http://circuitpython.readthedocs.io/ .. |Discord| image:: https://img.shields.io/discord/327254708534116352.svg :target: https://adafru.it/discord .. |License| image:: https://img.shields.io/badge/License-MIT-brightgreen.svg :target: https://choosealicense.com/licenses/mit/ .. |Weblate| image:: https://hosted.weblate.org/widgets/circuitpython/-/svg-badge.svg :target: https://hosted.weblate.org/engage/circuitpython/?utm_source=widget
