Getting data from file picker field in twig template

I have two file picker fields grabbing files from specific folders (audio and images). Well in my twig file I get the file (nameofaudio.mp3 and for the image an array object). But how do I get the url path?

.audio <!-- nameofaudio.mp3 -->
.audio.url <!-- does not work -->

.image <!-- array:1 [... -->
.image.html() <!-- does not work -->
---

Well, to make it work, you will need to use the path to the relevant page (folder).

{% set audio_folder = page.find('/media/audio') %}
{% set audio = header.filepicker.audio %}

{% set image_folder = page.find('/media/image') %}
{% set image = header.filepicker.image %}

{{ audio_folder.media[audio].cache.url }}
{{ image_folder.media[image].cache.url }}
