Even without bluetooth speaker and considering listening experience entirely depending on smart phone itself we can find that phone works like a charm and it works wonderfully.

If you want detailed audio experience then you can enable all forms of audio optimization. You can consider changing different settings of audio equalizer to make it more suitable and performance oriented.

How to Remove Audio from an Android Video

Two days prior today, we have some important  work at Cuttack and for this we hired a taxi and went to Cuttack and almost half past two ours work completed successfully. And while returning from Cuttack to Puri there was heavy rain and I decided to shoot some of videos  while returning from towards Puri. The road from Cuttack to Puri is in excellent condition. I decided to shoot nd dhoot almost three videos and while shooting I forget to mute the audio.

Daddy and one of my cousin brother was seating at the rear side of car and they were talking about experiences of today.  They were talking loudly so that they can be audible to each other. They started to talk about various topics beginning from cricket, to politics and various topics and they both are in some intellectual discussion.

In the mean time at the front seat, I was seating and decided to shoot videos and I shoot almost three videos from Cuttack to Bhubaneswar and then to Puri and then I decided to upload to YouTube after reaching at home. We reached at Puri and at ours home and then after taking rest I first preview it on mobile, to find out what is the condition of the video and to my utter surprise I found that I have not muted the sound while shooting and the conversations between daddy and cousion brother who happens to be a High court lawyer  their talks has been inside videos in the background.

I always edit videos with laptop with softwares but  this time I decided to do it with android itself and for this I want to find the free apps and that too without any advertisements and for this I do a bit of research for this. I found one app at last and I shall in this article let you know in detail about it and stay tuned and keep reading.

This article is not a sponsored article. I am sharing my experiences about it.  From Google play store se3arch for this app and then download into it and then it will ask for some permissions,  Allow it and the  open it and then you will find three menus, one is for audios and then next one is for videos and  the last one is more that is about miscellaneous.

From video touch mute to pick a video and then it will export video for few seconds and then there will be red sound button or mute button and touch it and below it will show the path in which it is stored and then it will be done within seconds. Then go to the extract route and then all audios are removed. So far after using  for few times so far in this free version no advertisement distractions is there and I find it very usuable so I decided to write this article.

This article is not about review of above mentioned app but how it  solve my problems and it works seamlessly and it removes audios from videos within seconds and during this cleaning process there is no hanging of phone and it completed within seconds. I am here talking about its free version which works nicely and this is also without any of advertisements distractions.

Apart from these functions you can convert audios and videos and can increase sound of MP# or audio files without any difficulties. You can convert MP3 files to WAV, FLAC, M4A, AAC AND OPUS audio formats. You can double the volume of audio files or half the volume of audio files and while doing this for the first time I found some advertisements which I did not find till the time I am removing audios from videos earlier. So far so good and so far all of my jobs such removing audios from videos or else increase volumes of MP3 files is working nicely without any difficulties.

How to remove one of two audio tracks in a mkv file?

With evolving technologies, we come across more and more newer and technological ways for the complete integration of one language to the other. Ever since the advent of Blue Ray disc we have seen how there is presence of two audios and mostly we do prefer the audios of our own native language. Most folks tend to see super hit Hollywood movies now come with second audio and most preferably in Hindi too.

Those Blue Ray discs with dual audios can be preserved with the MKV format and these formats are easily playable with VLC player. In these dual audio formats, there are two languages and the first or default is English of course and then the second language such as Hindi or other native languages. So in short one language is the domestic language in which the movie is shot and the other is the foreign language.

First we will learn how to use VLC player to use the dual audio and use the preferred audio to watch the movie. Open VLC Player and then click on MEDIA menu and then select the option OPEN FILE. Now, select a movie or video file and then click OPEN. This movie will now start to play in VLC PPLAYER.User left click on “Media Alt+M (menu item)” in “VLC media player”

1.User left click on “Media Alt+M (menu item)” in “VLC media player”

  1. User left click on “Open File… Ctrl+O (menu item)” in “vlc”
  2. User mouse drag start on “Position (indicator)” in “Select one or more files to open”
  3. User left click on “Audio Alt+A (menu item)”
  4. Audio track and then select the track of yours native language not the domestic language track of the movie file.

Then open AUDIO menu. Then go to option AUDIO TRACK. It will open the sub menu. Then select the language you want to hear with video. So, in this way, the default language of dual audio movie is changed while watching it with VLC Player. Now the question is if I want to remove one audio just like the one that is foreign language for me and I want to keep the native audio then how to do it.

There are some professional version of audio converter but those comes with price and there are some free version of such audio converter but that too come with the cache that the logo is there at the middle of the screen and that makes viewing of the movie difficult.

Yesterday, my mummy wants to see some movies related with sci-fi dual audios and when I put one that inside tablet, and when she opens the VLC player the default audio continues and I was away and she finds difficult to change from default audios to the audio of ours native languages.

When I returned she said she could not change it and then I decided to find the way to delete the domestic language on the video and out the only default language that is of my native languages so that when mummy open the VLC player and runs it she could find no hardship to change from default audio as there would be only one audio in it.

Then I begin my small research on it about how to remove one audio track from MKV file without conversion. At VLC Player for Windows play these files on my mobile and with computer so I do not want to change the format of a file but want to remove one audio of file and to keep the other audio that is suitable for my understanding.

One wonderful tool which is free and is also available fo Windows 64 too that is ‘MKVToolNix’. It is available for Arch Linux, CentOS, RedHat, Debian and many operating system and including Windows. It is available in Windows 32 bits, 64 bit is set up dot exe file format and then it is available in zip as a standalone file format. Before downloading the SHA-check sum number is there and you can use it to check the integrity of file system download.

In the download segment the link is there for older version of Windows packages and you can go there to download the older version of this software if you have older operating system computers.

Download MKVTOOLNIX


After installation of ‘MKVToolnix’ click on it to open MKVTOOLNIX GUI. Currently at the time of the article writing it is at the version of 20 and you can check from time to time for further updates of this software to keep it updates to its latest version.

1.Open “MKVToolNix GUI v20.0.0 (‘I Am The Sun’) 64-bit”

  1. User left click on “Add source files Alt+A (menu button)” in “MKVToolNix GUI v20.0.0 (‘I Am The Sun’) 64-bit”
  2. User left click on “Tracks, chapters and tags: (text)” in “MKVToolNix GUI v20.0.0 (‘I Am The Sun’) 64-bit” . Unchecked the domestic audio and keep check on native audio.
  3. User left click on “Destination file (push button)” in “MKVToolNix GUI v20.0.0 (‘I Am The Sun’) 64-bit”
  4. User left click on “Start multiplexing Alt+r (menu button)” in “MKVToolNix GUI v20.0.0 (‘I Am The Sun’) 64-bit”

Open this freeware and then at the bottom of the graphical user interface of MKVTOOLNIX click on ADD SOURCE FILES and select the destination directory where the dual file audio is ready to be played. In the frame of SOURCE FILES the uploaded videos will be seen with its name and its format as well as with it file size. Then just below of SOURCE FILES the column comes is TRACKS, CHAPTERS AND TAGS.

Here you will find that in the CODEC segment of TRACKS, CHAPTERS AND TAGS the first one is MPEG which is the video codec and do not uncheck it an then comes there are two codec mostly that of AAC and this means these are audio codec and this is high time to uncheck the one codec which you do not want to be there inside the audio codec.

How do you know about which codec to be the codec you want and for this prior to reaching to MKVTOOLNIX it is better to go for opening the video file with VLC PLAYER and then just run it and if the default running of file shows the domestic language that is the language in which movie is produced then for sure yours preferred language is at the second place of this file or vice versa.

Now comes to MKVTOOLNIX and here uncheck the first AAC and then the second AAC I ours native language in this file and the first AAC is the domestic language of the file. This can be changed in some other dual audio movies and for this you should always be careful about it. First check which audio os the native language of yours and which one is the other or domestic language of the movie and then do that similarly, in MKVTOOLNIX.

Then comes below and there choose the DESTINATION FILE and this means the video when starts removing the audio language of yours choice which means after completing the process of multiplexing it will put the output file at this locations which you preferred. If you do not change the default locations then it will put that file in the same at the same name with some additional letters.

Then click on START MULTIPLEXING which is located at the bottom of window and then within few seconds the removal of the audio which you opt for would be done and the now you can play yours preferred native audio and without waiting for changing of the audios and this way now you have successfully remove audio tracks from dual audio MKV videos without changing the file format. It comes within seconds a software only removes the audio and do not change any of the file format.

In the end this article is intended fo advice only and it is of user’s prerogative and responsibility to use this advice and it is important to back up copy of yours video file before using it so that if at any point of time there occurs wrong and file corrupted then you can look for the backup copy of it.
