Releases · hvianna/audioMotion-analyzer

What's new: 😷

New lineWidth and fillAlpha properties for mode 10 customization, so it can now work as an area graph (default), a line graph or a combination of both;
New barSpace property for customizable bar spacing in octave bands modes;
You can now provide an external AudioContext via audioCtx property in the constructor's options, allowing you to share the same context among different instances;
Custom error codes;
New version property;

Increased default spacing between bars in octave bands modes - to get the previous look, set barSpace to 1;
Improved accuracy when positioning the X-axis scale labels in octave bands modes;
Slightly improved vertical usage of canvas when the LED effect is active (removed the black line at the bottom of the screen);
Canvas context is now saved before calling the user callback function and restored afterwards, to avoid undesirable changes;
Several functions were refactored for improved legibility, memory usage and performance;
Improved documentation and demos;

The multi-instance demo should now work on browsers other than Firefox (it now uses a shared audio context);
isFullscreen property now correctly reads false (instead of undefined) when the analyzer is not in fullscreen (potentially breaking change);
Setting one of the callback functions to undefined with setOptions() now properly unregisters the callback (potentially breaking change);

audioCtx, analyzer, canvas and canvasCtx objects are now read-only (canvasCtx properties may be safely modified while inside the callback for onCanvasDraw);
frame and time properties are not exposed anymore, as they are intended for internal use only;
registerGradient() method now enforces the name argument being a non-empty string (throws an error otherwise);
Errors now return a custom object and some error messages have changed - use the new code property to identify errors in a reliable way.
