Audio polish

Learn gameplay feel with volume and pitch.

Audio Variation and Pitch Randomization

Frequently repeated sound effects such as footsteps, weapon swings, or gunshots sound robotic and grating if triggered at the identical pitch every time.

// Modulating audio pitch within a random window
audioSource.pitch = Random.Range(0.85f, 1.15f);
audioSource.PlayOneShot(hitClip);

Randomizing the pitch property of the AudioSource slightly on every trigger imparts natural auditory variance.

PlayOneShot and Audio Layering

To play overlapping sounds simultaneously without aborting prior playback, audioSource.PlayOneShot(clip) is used. This method is suited for rapid fire and explosions.

// Layering dual audio clips simultaneously on impact
audioSource.PlayOneShot(punchClip);
audioSource.PlayOneShot(debrisClip);

Stacking complementary audio clips (Layering) produces a much punchier and richer auditory impact than any single sample alone.

Exercise Audio pitch range test

Define a Start method. Inside, declare float pitchDegeri = 1.05f; and print "Ses pitch degeri: " + pitchDegeri to the console.

Show example solution

using UnityEngine;

public class AudioPolishTester : MonoBehaviour
{
    void Start()
    {
        float pitchDegeri = 1.05f;
        Debug.Log("Ses pitch degeri: " + pitchDegeri);
    }
}

Test yourself

Which audio property is modulated randomly to prevent repetitive sound effects from sounding artificial and robotic?
- Shader Pass
- AudioSource pitch
- Physics Gravity
- Mesh UV map
Show answer

AudioSource pitch — Modulating AudioSource.pitch across a slight range (e.g. 0.9 - 1.1) grants repetitive sound effects an organic, dynamic quality.

Play overlapping clip

audioSource.____(impactClip);

Show answer

audioSource.PlayOneShot(impactClip);
