How your WMA becomes a video
- The converter tool only turns audio into other audio formats, so the button opens the EchoWave editor with your WMA. There you add a picture, a waveform, or captions, and export a video.
- The editor exports MP4. Free exports are capped at 720p with a small EchoWave badge and a short end card; paid plans remove both and go up to 1080p, 4K, or 8K.
- The sound itself is not edited unless you change it. The video carries a picture for every second, so it is larger than the audio file.
