How to create audioclip in WebGL IOS - ios

Question

I'm trying to create an audio clip then automaticly goos up in frequentie.
This is allready working in the editor and windows but on IOS I get the error message
Creating stream audio clips is not supported in webgl. Creating clip as non streamed.
is there a way to do this that is also allowed in IOS?
What we have is this:
async void Update()
{
isPlaying = audioSource.isPlaying;
if (audioSource.isPlaying)
{
this.frequency += 150 * Time.deltaTime;
this.currentWaitTime += Time.deltaTime;
this.currentSampleTimer += Time.deltaTime;
var clip = CreateAudioClip();
this.audioSource.clip = clip;
}
}
private AudioClip CreateAudioClip()
{
var myClip = AudioClip.Create("MySinoid", this.sampleRate * 2, 1, this.sampleRate, true, OnAudioRead, OnAudioSetPosition);
return myClip;
}
private void OnAudioRead(float[] data)
{
int count = 0;
while (count < data.Length)
{
data[count] = Mathf.Sin(2 * Mathf.PI * frequency * position / 44100);
position++;
count++;
}
}
private void OnAudioSetPosition(int newPosition)
{
position = newPosition;
}
