1llest-waveform-vue

1llest-waveform-vue

A lightweight and controllable audio visualization vue3 plugin

Description

English ｜ 简写中文

This component is written using the native Web Audio API, and does not use any dependencies other than vue3 in the production environment. Of course, this means: if your target browser does not support the features of the web audio api, then my Plugins will also not apply. You can go to Browser compatibility to see the AudioContext line to check whether it is compatible with the target browser

Example - Live Demo

``bash
npm install 1llest-waveform-vue

| prop | description | type | default |
|:---------------|:----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|:----------------|:----------|
| url | the url of the audio file | String | - |
| requestOptions | the object passed to the fetch request function | RequestInit | - |
| lineWidth | the width of each vertical line that makes up the waveform | Number | 0.5 |
| lineCap | the style at the end of each vertical line that makes up the waveform | CanvasLineCap | round |
| lineColor | the color of each vertical line that makes up the waveform | String | #5e5e5e |
| samplingRate | indicates your audio sampling rate. The larger the value, the more lines the waveform will present and the higher the accuracy. But this value is not recommended to be too large, because too large a value will slow down rendering efficiency, the recommended value is between 8000 - 44100 | Number | 22050 |
| cursorWidth | indicates your cursor width | Number | 2 |
| cursorColor | the color of your cursor | String | #fff |
| maskColor | the color of the waveform mask layer | String | #fff |
| lazy | whether to enable lazy loading mode, if you want to display multiple waveforms as a list, this property is very useful | Boolean | true |
| skeleton | whether to enable the skeleton during waveform loading | Boolean | true |
| skeletonColor | the color of the skeleton | String | #232323 |
| interact | indicates whether you want the user to interact with the waveform | Boolean | true |
| fade | achieve fade-in and fade-out effects when playing and pausing audio, this can give the user a smoother listening experience | Boolean | true |

> When using the following events, you need to add the on- prefix in front, such as @on-init="initHandler"

| event | description | params |
| :------ | :----------------------------------------------------------- | :----------------- |
| init | the hook event before the waveform starts to initialize | Boolean |
| fetched | the hook event after accepting the audio file | Boolean |
| ready | the hook event triggered after the waveform completes all initialization and rendering to the page | Boolean |
| play | event fired when playback starts | Boolean |
| pause | event fired when playback is paused | Boolean |
| finish | the event triggered when the playback is completed (the playback completion refers to the completion of the entire audio) | Boolean |
| click | event triggered when waveform is clicked | Ref |

> You can call these methods directly on the waveform component instance, such like waveform_ref.value.play()

| method | description | return |
| :------------- | :----------------------------------------------------------- | -------- |
| play | trigger the playback method of the waveform so that it starts playing the current audio | - |
| pause | trigger the pause method of the waveform to make it pause playback | - |
| replay | this method can restart playing the current audio again | - |
| getCurrentTime | this method can get the current playing time. If you want to get the current playback time in real time, you can wrap it in the watchEffect hook | string |
| getDuration | this method can get the duration of the current audio, but this method must be placed after the ready hook event is triggered to get the correct duration | string` |
