Type | Description |
|---|---|
| uint | The sampling rate in hertz. |
Remarks
The audio sampling rate is the number of times per second a sample of audio is captured. Higher sample rates usually result in more realistic sounds and better sound quality, but files are larger. This is useful to know so that you can cater your audio to different devices. A VideoClip could have multiple audio tracks for different quality levels, which you can change depending on the device.

Examples
using UnityEngine;using UnityEngine.Video;public class AudioSampleRateExample : MonoBehaviour{ VideoPlayer videoPlayer; void Start() { videoPlayer = GetComponent<VideoPlayer>(); // Get the VideoClip from the VideoPlayer VideoClip clip = videoPlayer.clip; if (clip != null) { // Get the number of audio tracks in the VideoClip int audioTrackCount = clip.audioTrackCount; // Loop through each audio track and output their audio sample rate. for (ushort i = 0; i < audioTrackCount; i++) { Debug.Log("Audio track " + i + " has the following audio sampling rate: " + clip.GetAudioSampleRate(i)); } } else { Debug.LogError("No VideoClip assigned to the VideoPlayer."); } }}
