Give old audio a place to be seen
Many people have WMA recordings that deserve an audience: a band demo from years ago, a grandparent's voice, a school concert, a radio show. Video platforms and social networks do not accept WMA, and most do not accept audio files at all. When you convert WMA to MP4, the sound is placed in a standard video with an image, ready for YouTube, Facebook, Instagram, TikTok or a family chat.
Visual options
- Your own image: an old photo, the album cover or a title card with the date and place.
- A plain colour: simple and calm, good for long speech.
- A gradient: when you have no picture at hand.
- An animated waveform or spectrum: movement that follows the sound, so viewers know the video is playing.
Size and shape
Choose 1080p for YouTube, 720p when you want a smaller file or faster rendering, square for feed posts and vertical for stories, Reels, Shorts and TikTok. Old photos are often small or in a 4:3 shape; they look best on a square video or framed on a colour background.
Audio quality
The WMA audio is decoded and re-encoded for the MP4 file. Upload sites then compress it again, so start from the best WMA you have. A 64 kbps WMA voice recording will sound like itself, not better. If it is noisy or quiet, fix that first with Noise Reduction and Normalize; these steps make more difference than any video setting.
Before you start
Long recordings take longer to render because the video is made on your own computer. For social media, cut a highlight of under a minute with Cut. DRM-protected WMA files cannot be opened, so they cannot become videos. For more control or other audio formats, use Audio to Video.
