Embed an MP3

Copy-paste the embed code, then edit the required and optional attributes.

  secondary-font-family="'proxima-nova',Arial,sans-serif"

></type-3-player>

For more fine-grained control, use the custom-css attribute. CSS you enter will be injected within the component scope using an inline <style> tag.

"Listen to this page"

Instead of showing the player by default, you can show a smaller "Listen to this page" button.

When the user clicks the button, playback will begin and the full player will show.

Embed a narration

To embed a TYPE III AUDIO narration, just add the embed code with no custom parameters.

When your web page loads, the embed player will:

  1. Query the TYPE III AUDIO narration database for the current page URL.
  2. If a narration is found, load that narration.
  3. If a narration is not found, generate a narration via our "fully automatic" narration pipeline.

It's that easy.

N.B. To embed narrations, your domain must be registered as a TYPE III AUDIO client.

t3a-logobooleanhides t3a logo if value is "false"

Subscribe

Subscribe button will only be visible if at least one subscribe-url--[type] attribute is specified.

If link-to-timestamp="true", then: when the player loads, it will search your entire page for strings in the format [HH:MM:SS], [H:MM:SS] and [MM:SS]. These timestamp will become links. When clicked, those links will seek the player to the timestamp and start playback.

If the player should search just part of your page for timestamps, set the link-to-timestamp-selector attribute to any valid CSS selector.

N.B. If you have more than one <type-3-player> on a single page, you must set link-to-timestamp="false" on the players that you do not wish to seek using the link to timestamp function.

Floating player

If sticky=true, then the player will float at the bottom of the screen when the user clicks "play" and then scrolls the player out of view.

When the sticky player is visible, the .t3a-sticky-player-visible will be present on the <body> element.

Header play buttons

If header-play-buttons="true", the player will look for headings on your web page with text that exactly matches a chapter title from your audio. A "Play" button will be added to the left of matching headings.

To use this function, you must add CSS like the following to your stylesheet:

/*
  Styles for the TYPE III AUDIO player "heading play button" feature.
*/

/* Heading play button should not be shown on small screens */
.t3a-heading-play-button {
  display: none;
}

/* Set minimum width at which heading play button should be shown */
@media screen and (min-width: 850px) {
  .t3a-heading-play-button {
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    margin-left: -34px;
    margin-right: 10px;
    border-radius: 9999px;
    border: none;
    width: 1.5rem;
    height: 1.5rem;
    outline: none;
    cursor: pointer;
    transform: translate(0, 0);
    z-index: 10;

    /* Colour of the play button */
    background-color: #ddd;
    /* Colour of the play button icon. */
    color: #fff;
  }

  .t3a-heading-play-button:hover {
    /* Colour of the play on hover */
    background-color: #333;
  }

  .t3a-heading-play-button:focus {
    outline: none;
  }

  .t3a-heading-play-icon {
    display: flex;
    justify-content: center;
    align-items: center;
    margin-left: 2px;  
  }

  /* Refine this to match the dimensions of your heading typeface */
  h1 .t3a-heading-play-button { margin-top: 9px } 
  h2 .t3a-heading-play-button { margin-top: 9px } 
  h3 .t3a-heading-play-button { margin-top: 3px }
}

If you'd like to show the header play buttons only if the user has started audio playback, you can use the following CSS:

.t3a-heading-play-button {
  display: none;
}

.t3a-playback-started .t3a-heading-play-button {
  display: block;
}

Analytics events

Use the analytics attribute to send events to your preferred analytics service. Options:

  • google: send events to Google Analytics using window.gtag (gtag("event", event.type, event)).
  • segment: send events to Segment using window.analytics (analytics.track(event.type, event)).
  • custom: player will send analytics events to window.t3aAnalytics(event.type, event).
  • none: player will not send analytics events.

Events will only be sent if the relevant window.x function is defined. If a given visitor is blocking your analytics service via their privacy settings, the function will be undefined and events will not be sent.

If you do not specify an analytics value, the player defaults to using Google Analytics.

  • episodeAuthor: author of the narrated article, if known

Privacy note

By default, the embed player also sends the analytics events above to the TYPE III AUDIO internal analytics service. We use a GDPR-compliant tracking mechanism for which visitor consent and cookie notices are not required. No personally identifiable information is collected, so our usage analytics has no legal implications for your privacy policy.

We use this information to improve the player, provide usage reports to clients and assess the impact of our work.

If you wish to opt-out of this tracking, send us an email.

WordPress plugin

Install our WordPress plugin to enable the [type_3_player] shortcode.

Use the shortcode as follows:

[type_3_player mp3-url="https://dl.type3.audio/episodes/radio-bostrom/11335090-base-camp-for-mount-ethics-2022.mp3" author="Nick Bostrom" title="Base Camp for Mount Ethics"]

You can use any of the attributes listed below.

The shortcode loads JavaScript automatically, so there's no need to manually load player.js.
