With controls for play, pause, stop, mute/unmute, adjustable volume, and playlist support, users can seamlessly manage their audio content. Customization options allow for tailored design integration, while features like image export, speed control, markers, and dynamic event triggers enhance user engagement and navigation.

How to setup

  • Place the plugin’s element “Audio Player - Waveform” on the page.
  • Define the audio file and the colors and options you would like to have in your player.

Plugin element “Audio Player - Waveform


Unplayed Wave Color
The color of the unplayed part of the wave.
Played Wave Color
The color of the played part of the wave.
Waveform Type
The type of waveform visualization.
Cursor Color
The color of the cursor / selector. The cursor represents the current playback position within the audio file.
Audio File
The audio source file.
Stop all instances on play
This is useful when you have multiple instances of Waveform on the same page. If this value is yes, all players currently playing will pause/stop(depends on “Stop or Pause”) when this player starts playing. If set to “no” then all instances when this player starts playing other will not stop, will continue playing simultaneously.
Reset when stopped
When “Stop all instances on play” is checked, then this property set to “yes” makes all other instances stop when current instance plays, set to “no” makes them pause instead.
The speed of the Audio Player. 1 is normal. 0.5 is 2x slower. 2 is 2x faster, etc…
Set property to “yes” this box if you want the Audio Player to be muted by default.
Hide scrollbar
Whether to hide the horizontal scrollbar when one would normally be shown. property provides a way to customize the appearance of the WaveSurfer waveform visualization by controlling the visibility of the scrollbar within its container.
Hide Cursor
Hide the mouse cursor when hovering over the waveform. By default it will be shown.
Normalization ensures that the loudest part of the audio reaches a specified level without clipping or distortion, thereby improving the overall clarity and consistency of the audio playback.
Skip Length
Number of seconds to skip with skipForward and skipBackward actions.
Preload Peaks
Check this box if you want to preload the peaks from your database for instant-rendering. By supplying this data, WaveSurfer can render the waveform more quickly and smoothly, as it doesn't have to calculate the peaks itself from the audio file.
Peaks Data (JSON fromat)
(Optional) This field will be the peaks of the current audio file as JSON format when “Preload Peaks”. It has to be the same output as what the custom state "Peaks Data (JSON)" outputs !
Consider Audio as Played (sec)
Number of seconds that the audio has to be played to be considered as played. Once this number of seconds has been reached on the current audio, the event "Current Audio File can be considered as Played" will be fired. It may help you to build a listening counter feature.
== Plugins Additional Features ==
Cursor Plugin
Determines whether the cursor feature is enabled or not. When enabled, player displays a vertical line that moves along with the users’s directions on the audio file. When disabled, this cursor line is not displayed.
Cursor Color
This property defines the color of the cursor line.
---Markers - - -
Markers Plugin
This property determines whether the markers feature is enabled or not. When enabled, player allows users to add markers to the waveform, indicating specific points of interest, such as song sections or timestamps.
Initial Markers
(Optional) This property represents the initial set of markers that are loaded when player initializes. It has to be in JSON format, exactly the same that what the custom state "Markers Data (JSON)" gives you as output.
---Media Session-—
Media Session
This property determines whether the integration with the Media Session API is enabled or not. The Media Session API provides metadata about the currently playing media to the operating system, allowing for better integration with system controls such as playback controls on lock screens or notifications.
(Optional) The song title.
Artwork (Image)
(Optional) The image that will be displayed.
(Optional) The artist.
(Optional) The album.
Only download on start? 💬 ⚠️.
⚠️ WARNING: If you are not using the Peaks Data, the waveform will NOT be displayed until the user clicks on "Start". When this option is enabled, the audio file will only start downloading when the start function is called. This avoid downloading long lists and improve performance. If you have a web page with multiple WaveSurfer instances but you don't want to fetch all the audio files immediately upon loading the page, setting thsi property to “unchecked” allows you to fetch audio files only when the WaveSurfer component is initialized.
Allow Downloading
Enables the audio to be downloaded by users
