Thread blocks on MicrophoneRecord.Start()

[SirPerryyy]

When the methoD MicrophoneRecord.Start() is called, the main thread freezez for about a second. This methon cant be executed on another thread. I have no idea on what causes the problem
` InputAction record;

WhisperManager mg;
MicrophoneRecord microphoneRecord;
float time = 0;
readonly float maxTime = 5f;
string text;
public bool recStarted = false;

void Awake()
{
    mg = gameObject.AddComponent<WhisperManager>();

    microphoneRecord = gameObject.AddComponent<MicrophoneRecord>();   
    microphoneRecord.OnRecordStop += MicrophoneRecord_OnRecordStop;

    record = InputSystem.actions.FindAction("Record");
    record.performed += Record_performed;
}

private void Record_performed(InputAction.CallbackContext obj)
{
    RecordStart();
}

private void Update()
{
    if (record.IsPressed() && time < maxTime)
    {
        RecordStart();
        time += Time.deltaTime;
    }
    else if ((!record.IsPressed() && recStarted) || (time > maxTime && recStarted))
    {
        if (time > maxTime) Debug.LogWarning("Out of max recording time!");
        microphoneRecord.StopRecord();
    }
    
}
private async void MicrophoneRecord_OnRecordStop(AudioChunk recordedAudio)
{
    time = 0f;

    var res = await mg.GetTextAsync(recordedAudio.Data, recordedAudio.Frequency, recordedAudio.Channels);
    if (res == null)
        return;

    text = res.Result;
    Debug.Log(res.Result + " | " + res.Language);
}


private void RecordStart()
{
    if (recStarted) return;
    recStarted = true;
    mg.language = "en";
    microphoneRecord.SelectedMicDevice = Microphone.devices[0];
    microphoneRecord.maxLengthSec = (int) maxTime;

    microphoneRecord.StartRecord(); //THE PROBLEM IS CAUSED HERE
    Debug.Log("started");
}
