While I’m personally not that much involved in the production of pure audio / radio content, I have noticed that there has been increasing demand for a way to make audio stand out more in social networks that primarily address the eye. There are some web tools like Headliner, Audiogram or Auphonic and the relatively popular iOS-only app Wizibel that basically take an audio file, generate a visual waveform animation based on it and create an mp4 video file as the end product which is easily shareable on Facebook, Twitter, Instagram etc. Usually you can also add a still image or text to spice it up. Some call this type of audio visualization an “audiogram” and I think it’s particularly useful for audio teasers (for a podcast for instance) or audio content that is only a couple of minutes long. There have been a few options on Android as well (ChkSnd, Audio Vision for Videomakers, Avee Music Player) but while they weren’t exactly bad, they all had some shortcomings. A couple of days ago however I stumbled upon a very promising app that’s relatively new (it was released November 2019): Visualization Video Maker.
After spending a couple of days with the app, I’m sure this one’s a keeper – it’s the best I have encountered on Android so far. It has a good, clean and easy to use UI but still a lot of options to customize the look of your audiogram. The basic workflow is very simple: You start with a given spectrum, then choose your audio file and optionally add a background photo/graphic/text. That’s about it. Of course you can dig a bit deeper and customize different aspects of your video, the app’s UI makes it very intuitive. You can choose from a set of animated spectrums/spectra (bar, circle, line, texture etc.) and define size, color, position and opacity among other things. There’s also a bunch of options to edit your text or photo. You are even able to change the layering of spectrum, text(s) and additional photos/graphics to decide which one is represented as the top layer. Everyone familiar with the layering of graphical elements like in Photoshop for instance should feel at home. You can also “mute” layers which basically disables them so they are hidden from the preview but still in your layer stack.
The app supports the import of different audio formats/codecs including wav/pcm, mp3 and m4a/aac. However I have found that there seems to be a bug affecting LG devices where you get an error message when trying to use wav files with pcm codec (mp3, m4a/aac on the other hand work just fine). I tested this on an LG V30 and LG Q6. I had no problems with wav files on a whole bunch of other Android devices.
Let’s take a quick look at things that could be improved: 1) The video aspect ratios are limited to 16:9 landscape, I couldn’t find any square or portrait format options. When considering that the app is a great tool to present or tease audio in social networks, more format options would be great to have, particularly a square 1:1. 2) From what I can see the app is lacking proper share integration with other apps via the Android share sheet. Yes, you can pick your audio file through the media browser / audio file system but depending on the recording app you used for recording your audio file, finding these files can be a bit annoying, especially if you have lots of audio files on your device. So it would be great to be able to share the recorded audio file from your recording app of choice directly into VVM. I have tried this with a couple of common Android audio recording apps but never was VVM listed as a target when opening the share sheet so I think the problem is on VVM’s side.
In the export panel you can choose between the following video resolutions for your mp4 file: 1920×1080, 1280×720, 854×480 and 640×360. You can also define a custom video bitrate while the frame rate is automatically 30fps. The audio bitrate of the exported video is 128Kbps (no matter the input), which is pretty ok for sharing on social networks but could still be raised a bit to please the more audiophile crowd.
VVM is basically free without any kind of watermark but to export your project you have to watch a 30 sec advertisement if the export resolution is 720p or above or the length over 3 minutes. I suppose this is a pretty fair deal. Unfortunately, there are no in-app purchases whatsoever to avoid watching the ad. So even if you are willing to pay, there’s currently no way. It would have been nice to have the option for a one-off purchase of the app which will then let you always go straight to the export.
And here’s a bonus tip: If you use Visualization Video Maker in combination with the app AutoCap you can even get automatic captions for your clip! Just take the exported clip from VVM into AutoCap and let this app do its magic. While AutoCap is free to use as well, you will have to pay to get rid of the watermark here.
Last thing: I just noticed that there’s actually now an Android app version of Headliner (iOS version as well) but so far I wasn’t able to import/upload any audio files. Despite meeting all the requirements (mp3/wav file, under 500MB and under 2 hours length) I always get an error message “File problem. Please make sure your file is a MP3 or WAV, under 500 MB & shorter than 2 hours”. You also need to create an account for the app so VVM definitely looks like the better mobile option to me at this point.
