Create parameters on audioSource

My best answer would be to create a simple serializable class, with 2 public variables to hold the information you wish it to handle:

 using UnityEngine;
 using System.Collections;
 using System; // <-- This is key here, allows you to use the [Serializable] above a class.
 
 [Serializable]
 public class MyAudioThingy
 {
     public AudioClip clip;
     public float sampleFloat;
 }

And then in your AudioHandler class, or what you wish to call it you can do as so:

 using UnityEngine;
 using System.Collections;
 
 public class Test : MonoBehaviour
 {
     // This can be seen in the inspector
     public MyAudioThingy[] sample;
 
     void Start()
     {
 
     }
 
     void Update()
     {
 
     }
 }

Hope it helps! :)

Okay, you can use the 'Serializable' attribute to allow visibility of class properties within the Inspector. Simply create a class within the scope of your MonoBehaviour and give it the Serializable attribute to allow visibility within the Inspector. Then create a public instance of the class and fill out the data inside of the Inspector.

Here is a very basic script as an example.

 public class AudioSetup : MonoBehaviour 
 {
     [Serializable]
     public class AudioData
     {
         public AudioClip AudioClip;
         public float FloatValue;
     }

     // You can create a single instance of the class.
     public AudioData SingleInstance;

     // You can also maintain a list of instances and store different data for each.
     public List<AudioData> ListOfInstances; 

     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 }
