Frequently Asked Questions
How does the AI audio to video generator work?
Upload any audio track (MP3, WAV, M4A, or voice memo). wavreel uses Whisper AI to transcribe your audio, semantic AI to select matching cinematic stock b-roll footage, and in-browser WebCodecs to render a full 1080p MP4 video with synced subtitles in under 2 minutes.
Can this AI app change any audio file into a video?
Yes. Whether you have an audiobook chapter, podcast clip, voice recording, speech, or narration, wavreel converts the audio into dynamic vertical 9:16 or horizontal 16:9 MP4 video.
