That’s it for the implementation - time to style! Let’s begin with adding some options into WaveSurfer.create to get the waveform looking better. Wavesurfer.js provides a function called getCurrentTime(), but I don't know how to implement it, so the time is displayed next to the play button. This is a safety net in case the button’s onClick gets called with () before isPlaying() is defined. drawBars (peaks: number number, channelIndex: number, start: number, end: number) Draw a waveform with bars. Width: 380 mm : Unit Weight: 4.81 kg : products found.

destroy () This is called when wavesurfer is destroyed. WAVESURFER 3024Z Teledyne LeCroy Benchtop Oscilloscopes 200 MHz 4CH 4/4 GS/s 10 Mpts/ch DSO datasheet, inventory & pricing. A JavaScript Sound API supporting MP3, MPEG4 and HTML5 audio + (experimental) RTMP, providing reliable cross-browser/platform audio control in as little as 10 KB. A JavaScript library for rendering music notation and guitar tablature.

Users of the binary Windows/Linux releases need never know or worry. createWrapper () Create the wrapper element, style it and set up the events for interaction. Navigable waveform built on Web Audio and Canvas.

Snack is only of interest for advanced users and developers. Snack provides all low level functionality while WaveSurfer is the application which also contains a library of high-level visualization components.

Note that we added an initial value of isPlaying: () => false to waveSurferRef. WaveSurfer is built using the Snack toolkit and the Tcl/Tk language. I have yet to discover an easier/more performant implementation that can rely on Wavesurfer as the single source of truth and lift any necessary state up.

This approach lets us rely on React’s diffing and rerendering to update the DOM outside of the Wavesurfer instance, in the case of the play/pause button. There is a downside with this implementation: we must duplicate Wavesurfer’s own isPlaying() state into React with toggleIsPlaying(()), creating potentially two sources of truth with React’s state and Wavesurfer’s state. Here we set the element to display: flex and give it a maximum width for larger desktop displays.
