For those who want to convert audio files such as podcasts to videos and upload them to YouTube etc., or those who want to convert WAV to MP4, there is a way to add an audio spectrum such as a waveform or a sound bar instead of just a still image. For those who want to know, we will introduce a simple and free method.
Convert audio to video and add audio spectrum
The main steps are as follows. Now you can convert WAV audio files to videos with waveforms. This free software is recommended for people who want to convert audio to video with waveforms on Windows. Recommended for people who want more people to listen to their audio broadcasts by posting their own podcasts on YouTube or Instagram (IGTV).
- Set up AviUtil and plugins on Windows (free software)
- Prepare a WAV audio file and load it into AviUtil
- Insert audio spectrum into timeline
- Output to video such as MP4
- If it is an MP3 audio, there will be noise due to the compatibility with the MP4 plug-in (it is better to convert it to WAV in advance)
Only this. Surprisingly, even though AviUtil is a free software for Windows, it comes with audio waveform effects by default.
In this way, you can stream audio with waveforms as a video.

If you search, you will find a lot of information about installation and detailed operation of AviUtil, so in this article I will focus on understanding the overall process.

Arrange audio and still images in AviUtil
When you start AviUtl, only one screen appears, but if the above plug-in is added, you can display windows such as the timeline that are similar to video editing software.
Once the timeline is displayed, drop audio and still images. Then, you can arrange and operate it in the same way as with general video editing software.
Insert audio spectrum (waveform)
In AviUtl, right-click on the empty timeline and select “Add Media Object → Display Audio Waveform”.
A horizontal dotted frame will then appear in the main window. All you have to do is enlarge it and place it wherever you like.
When you play in the playback window, the soundbar (waveform) will automatically move.

There are 5 types of waveforms to choose from (TYPE2 is quite thin). You can select from the TYPE item in the waveform properties. You often see TYPE3 and TYPE5.
You can also change the color of the waveform from the details window.

A save dialog will appear on the screen, so save it as a file format such as MP4 and it will be output.
An error occurs when converting AviUtl audio to video.
If an error occurs, such as the conversion codec or plug-in version, there may be multiple causes, so I will list the pages that I found helpful.
Also, the fixed method isChange single path to automatic multipathWhat I did. It took a lot of time, but I was able to do it.There was also an article that said that changing the audio encoder from AAC was successful.
However, this depends on a case-by-case basis, and it is difficult to determine which method is better in different environments.
Please try searching on the following pages or using related specific keywords.
You should now be able to convert audio files such as podcasts into videos with audio spectra (waveforms). AviUtl is a standard free software for Windows, so it is recommended that it has a lot of information.

A web service that converts audio to video
If you are using a Mac, you may want to look for a web service that converts audio to video, such as podcasts.
You should be able to find some that are free, and others that have watermarks but can be used for free. Some of them allow you to add special effects in addition to the audio spectrum.
＞＞Headliner – Promote your podcast, radio show or blog with video
Headliner is one of them. Although it is only available in English, podcasts are popular overseas, so there seems to be a need to convert audio into video, and as you can see from the site, there are quite a lot of video templates.
Converting just still images to video is not enough! If you are such a person, I think it would be a good idea to look for such an audio video conversion site.
