# Upload Voiceover

This feature allows you to upload your own voiceovers to any Supademo, giving you you more flexibility when creating polished, professional demos that sound the way you want them to. Whether you’re using a professional voice actor, adding a personal touch, or narrating in your own style — custom audio can help make your Supademo feel even more authentic.

From the **Manual Voiceover** tab from the **voiceover panel** of a Supademo, simply upload an MP3, MP4, WAV, or other common audio file **on a per-step basis** directly within your Supademo. Each step can have its own audio track, which will play back during your demo.
