How to export audio from the recorded video using Replay?

Jun 04, 2015

I have done a screen recording using articulate replay. After publishing the video doesn't look very good but the audio is good. Now I want to export my audio and keep and delete the video. So that I can use that audio if I need it. Please help me doing this.

Sorry John that we've let you down on this feature - but we're always interested in hearing more about the things you'd like to see in Articulate products and how those would help you with your development timeline. If you'd like to share some more details here or send it as a Feature request here, that'll get into the hands of our Product team.

If it's any help to anybody :
1- Publish the project to a video format.
2- Import to Adobe Premiere
3- Export to a Wav format.
4- Import in an audio software. Do the cleaning you need to do in your sound.
5- Import the audio back in Replay.
6- Mute the sound in the webcam track.

But, yeah, a lot of work for something that should be quite simple.

Greetings, Jen! 😀

It sounds like you have a Replay 360 audio clip that you need to import into Rise 360, is that right? Right now, there isn't an audio export feature in Replay 360. I'm happy to bring this idea back up to the team, and feel free to share any other thoughts here!

In the meantime, here's one approach:

  1. First, publish your Replay 360 project as an .MP4 file
  2. You'll need to use a converter tool to change the .MP4 file to an audio format (I'm hopeful the community can recommend the best tools for this!)
  3. In Rise 360, edit an existing lesson or create a new one
  4. Select Multimedia from the block library, then click Audio
  5. Select the converted file to add it to your Rise 360 course

Would that work for your project?

Wow. When this popped into my email, I had to really remember what this thread was all about. 

I don't have or use Articulate anymore, so I don't remember all the publication steps for Replay. Basically you want to end up with an .mp4 video file at the end. 

The steps are based on this article from HowToGeek, which is old, and I am using the VLC 3.0.11.  

Once you have the .mp4 file from Replay, open up VLC. 

From the "File" menu, select "Covert & Stream."

A new dialogue box will open up. 

Drag your file into the drop zone (or click the "Open media.." button and navigate to where your file is). 

In the "Choose Profile" area, select one of the audio only options, such as "Audio - MP3". 

Once those areas are set, click on the "Save as File," set the save location and file name, click "Go!," and let it run. It can take a little bit depending on the size and length of video file you are pulling from. 

From here you are able to edit the audio in your program of choice, I tended to use Audacity. 

Optional steps/ information:

Something to remember, careful with the audio length and try not to remove anything, as this will mess up the audio syncing to the video when you patch them together. 

When you are done with the audio editing, export to either mp3 or wav. I am not sure.

(this next part is a little hazy). 

In Replay, open your published video file that you pulled the audio from in source A and mute the audio for source A. 

Add in the newly edited audio into source B. The wave form of both audio should be similar in shape. 

Scrub through and make sure the audio is dong what you think it should be at key points. 

Republish the video with a new title. 

So, I think that wraps this up. With all of these steps, save your work often in case something doesn't work right.

I hope this helps and good luck.

Interesting that Articulate always questions the use case for obviously needed functionality.  My use case is recording a screencam using a headset.  With a headset recording you always need to clean up the audio background, but there is no such feature in Replay. I have a 43-minute screencam, where the flow is:

1.  Save replay file (4 minutes)

2. Publish to mp4 (25 minutes).

3.  Open mp4 in Wavepad and clean up the audio (auto spectral subtraction).  Save as mp3. (1 minute total)

4. As suggested by others, mute audio on trackA and import audio on trackB. (1 minute). 

5.  Save replay again (4 minutes)

6. Publish mp4 again (25 minutes)

So the benefit of including audio cleanup in Replay is 29 minutes (eliminate steps 5 and 6).  Alternatively they could make better use of PC resources to speed up the Publish function.

In fact, even after all this time, the method of extracting audio from video using VLC is still basically the same. You can save your video in MP3, OGG, FLAC, etc with VLC media player.

However, note that if the original audio has multiple channels, the audio extracted with VLC will only retain two of them (usually L and R). That might be fine for daily use. But for further editing, things can be a little tricky (because this actually loses some data).

If your screen recording is in the MKV format, the best way is to use MKVToolNix. It has a GUI for easy use, and it is totally free. But the downside is that this GUI can only work with MKV files.

It's better to use FFmpeg for videos in other formats like MP4. FFmpeg can preserve the original audio quality (lossless). The downside is that you may need to know a bit about the command line, but it's not too difficult. Detailed steps can refer to in this article.
