Ever tried to edit sound using Audacity? Did you see the random error that just pops up for some video files? While you could listen the sound from Video, Audacity simply rejects the file from opening? If you are nodding head for most of these questions, you have experienced the same moment that I have been through recently.

As already explained in my prior article, I have been using OBS Studio for screen and audio recording. And most importantly everything is captured in the raw state, no video filters, no audio enhancements – everything in plain raw format. Well, it is true that the output size is unusually large. This gives me the advantage to process the video and audio contents using specialized software(s).

Workflow

Due to the unavailability of some softwares on Ubuntu, I had to switch back to Windows. It gave me an edge to experiment few effects which are easily available for Windows And Mac. Naturally, I had to reinstall everything fresh – OBS Studio, Blender, Audacity etc.

I had a repository of few recorded videos which needed editing and hence I thought to begin with my workflow

1. Open video in Audacity and tune sound.
2. Use Blender to merge audio and video.
3. Edit unwanted portions in Video.
4. Add background music, intro slides etc.
5. Render the Video with HD quality settings.
6. Use special softwares for Professional editing.
7. Render Video again.
8. Use Handbrake to compress the file and retain HD settings.

Roadblock – Audacity fail

The workflow is pretty simple and with the fresh environment, I started with the first step. And here comes the bang!!! Audacity simply denied opening the file. It out-rightly rejected and kept annoying me that it can’t do the usual job.

Open Mp4 On Audacity

This was quite frustrating, I never faced this issue on Ubuntu and suddenly what happened on Windows. I tried restarting OS, uninstalled audacity, installed codecs and nothing seems to work.

I was losing the time and with every second the pressure was just mounting on me.

Audacity Mp4 Codec

I am running on some tight schedule and this video needs to be published somehow. Audacity continued to mock me and with its poker face, it started getting on my nerves.

Abracadabra

Well it was time to prove who gives up. I used my tricks of doing Google search, going through the forums, searching through YouTube videos and finally. I found the solution – it was pretty simple.

Due to licensing issues, Audacity doesn’t bundle some of the softwares and one amongst them is FFmpeg.

For those who are not aware of FFmpeg, it is a super duper popular, life saver, multimedia framework.

Yeah, FFmpeg is literally that great, believe me, it has saved countless hours of many living souls and some aliens too.

No Magic

Aha, nothing magical, the answer for this error actually lies in Audacity itself. Open Audacity, go to Edit > Preferences > Libraries. You will see some suggestions to download libraries. One of them is FFmpeg. Click the download button and you will be redirected to an HTML page.

Follow the instructions for your operating system and install FFmpeg distribution. Once the installation is complete, simply restart Audacity and VOILA!!! You should now be able to import a majority of the formats into Audacity.

And yeah, here is my Happy Audacity screen with Audio waves

This detailed and step by step tutorial will show you how to extract the audio from an MP4 video file, using Open Source (free) software. That way you can listen to it on your computer, smartphone, iPod etc, or burn it to an audio CD.

Background

MP4 files are one of the most common format for video recording devices (the GoPro is a good example). There may come a time (or lots of times) when you want to listen to the file but not necessarily watch it. These steps will show you how to create a separate “audio only” file.

Note: while the the steps and images in this guide are from a Mac users perspective, nearly everything is identical for Windows users. Not only is the software available for OS X and Windows (and Linux!) – it looks the same no matter which you’re using.

Extract Audio from MP4

Let’s jump right in!

Windows 10 Won't Play Mp4

1. If you don’t have the wonderful audio software Audacity already installed, head over to the Audacity download page (link opens in a new tab/window). Download the version for your Operating System (Windows, macOS, Linux)
2. Open Audacity, select File and then Open…
3. Navigate to the MP4 video file that you want to copy the audio from. Select the file by clicking on it once, and then click the Open button. It may take a bit to open the file – the larger the MP4 file, the longer it will take to open.
4. NOTE: at this point you may get an error message. If you do, fear not, the solution is simple. Just follow the steps outlined in this brief guide (opens in a new browser tab/window) to add “MP3 support” to Audacity. Then repeat steps 2-3 and you won’t ever have that problem again.

   A new Audacity window will appear, displaying all of the audio information from that MP4 file.

5. With that window open, select File and then Export…
6. From here you can choose the format you want to save the audio as. If you’re going to burn it directly to CD, select .wav so that you get the highest possible audio quality. Otherwise you can select MP3.
7. Now click the Save button.
8. Enter the song metadata if appropriate, then click the OK button.
9. Now the audio will be extracted and saved.
10. When finished, go and check the audio file to make sure everything worked – and then you’re done!
