People downloading videos from YouTube are recently facing this problem. The video is playing normally on stereo speaker devices like earphones, headphones, laptops, and smartphones from YouTube. But it would go mute when we play the same video on mono speaker devices.
We were able to troubleshoot and fix this issue. So, if you are facing the same issue, don’t worry; we have a quick and easy solution for you. Let’s first understand the problem a little bit.
Stereo vs. Mono Audio
Firstly, we suggest you get a bit of knowledge about Stereo and Mono audio for a better understanding of the problem.
So, stereo audio has 2 audio channels, whereas mono audio has 1 audio channel that is left and right channels. You need 1 speaker and 1 microphone to record and listen in mono audio, but for stereo, you only require two of each speaker and microphones.
So, if you must have noticed before editing or recording video, that mono audio has only 1 audio waveform, whereas stereo has 2 audio waveforms. The 2 audio waveforms are there because each of the waveforms is from the left and right speakers.
In general, all the audios are recorded in mono audio form. But when it’s time for video editing, the video editing software splits the mono audio form into stereo, which in turn makes the audio playable on both stereo as well as mono speakers. In this case, the software converts the mono to stereo but inverts one of the waveforms.
Detecting the Problem
We will explain the method to detect any problem with your audio clip in Audacity. Firstly, open that file in Audacity, and if you don’t have it then you can download it. You will be able to zoom in on the waveform of the audio in Audacity. You will see that some of the waveforms may be out-of-phase. So, play this audio file now by pressing the spacebar. Your audio is now in the stereo modem if you are able to hear it.
Click on the top-right corner menu if you want to replicate this audio on mono devices. There you will see an option of Split Stereo to Mono option; click on that. When you want to return to the Stereo mode, then from the same menu, select the option of Make Stereo Track. Lastly, if you want to see if we are going in the right direction then, check if the audio is audible in stereo mode. And it should not be audible in mono mode. Now, let’s see the next step on how to fix this issue:
How to Fix the Audio
Firstly, you have to export the audio from your video.
Now open the audio file which is not working in Audacity. After the import is done, click on the dropdown menu at the top-right corner and then select the Split Stereo Track option.
Select the audio tracks by clicking on the left side of the audio waveform.
After you have selected the audio wave, go to the effect at the top menu bar and click on Invert. Now this will invert your audio waveform.
Note: Once the process is done, both your audio waveforms will have the same structure. You can also test it by listening to the audio in stereo and as well as mono from the drop-down menu.
Conclusion:
This is how you can solve the problem of YouTube videos with no sound. We recommend you find an old smartphone or laptop that has a mono speaker and listen to them through that. Hope you find this information useful.
