Workaround for audio delays in Android devices

Questions & Answers

I am working on a rhythm game with unity. I want player to tap to beat. The visuals also change according to beat

I am using following method;

public void StartPlayingAudio()
    {
        double startTime = AudioSettings.dspTime;
    
        samplePeriod     = 60f * audioSourceBeat.clip.frequency / musicTrackBPM;
        sampleOffset     = (60f * audioSourceBeat.clip.frequency) * 0.5f / musicTrackBPM;
        nextBeatSample   = (float)(startTime) * audioSourceBeat.clip.frequency;
    
        audioSourceBeat.PlayScheduled(startTime);
        StartCoroutine(CountBeats());
    }
    
    IEnumerator CountBeats()
    {
        while (audioSourceBeat.isPlaying)
        {
            currentSample = (float)AudioSettings.dspTime * audioSourceBeat.clip.frequency;
            if (currentSample >= (nextBeatSample + sampleOffset))
            {
                nextBeatSample += samplePeriod;
                beatDisplay.DoSomething();
            }
            yield return new WaitForSeconds(0);
        }
    }

When I test this code on different Android devices there is significant latency. And it is changing from device to device.

Is there some workaround for this?
