How to Extract Audio from Video with Audacity and FFmpeg

[00:00] in this video I'm going to show you how

[00:02] to extract audio from video and we are

[00:05] going to use audacity which is a free

[00:07] and open-source software and probably

[00:10] the best for manipulating audio and

[00:13] videos normally it is considered as an

[00:15] audio tool but if you want to separate

[00:17] only audio from a video you can also do

[00:20] that in audacity why you want to do that

[00:22] that I will explain at the end of this

[00:24] video because you clicked on this video

[00:26] because you want to know how to extract

[00:28] audio from video so first I explain this

[00:30] and then I will show you what could be

[00:32] the reasons why you might want to do

[00:34] that so without further Ado let's get

[00:36] started after a short

[00:38] [Music]

[00:44] break hello and welcome to my channel my

[00:47] name is Tahir and I make videos about

[00:49] various applications and software mostly

[00:52] about educational technology so I would

[00:54] highly appreciate if you hit the

[00:55] Subscribe button and also the

[00:57] notification Bell to get notified

[00:59] whenever I post a video on this channel

[01:01] I hope that you already know about

[01:03] audacity and you have installed this on

[01:06] your computer if not you can simply type

[01:08] audacity in Google and you will reach on

[01:11] this website and you can download

[01:13] Audacity now I have opened this software

[01:16] and this is my file explorer in which I

[01:19] have one video as an example and

[01:22] extracting audio from this video is very

[01:25] simple in audacity you simply drag and

[01:28] drop in this area if you have recently

[01:31] installed audacity then you will see

[01:33] this message and what this message is

[01:35] saying is that you have to add a library

[01:38] to audacity in order for you to extract

[01:41] audio from a video and that library is

[01:44] called FFM Peg and the message is saying

[01:47] that without FFM Peg audacity is unable

[01:51] to open this file and if you have

[01:53] installed that library then you will

[01:56] simply get the audio opened in this

[01:58] audacity which you can export as an MP3

[02:01] file and you are done so it's a very

[02:04] simple process you simply have to drag

[02:06] and drop your video and you will get the

[02:08] audio now let's see how you can install

[02:10] FFM Peg and we don't want to install

[02:12] from a spammy website so let us ask Odes

[02:16] from where should we install this

[02:18] library now what I need to do is I click

[02:20] on edit and at the very end we have this

[02:23] preferences I click on that and on the

[02:26] left hand side I have to click on this

[02:28] libraries and I can see this message FFM

[02:32] Peg Library not found and then there are

[02:34] two buttons locate and download so we

[02:38] should first click on this download so

[02:40] that we only go to the authentic website

[02:43] so I click on this download and it will

[02:46] open this page on this page I click on

[02:49] installing FFM Peg and now we are on

[02:52] Audacity website on this website there

[02:55] is a link lame. bueno. org and because

[02:59] this link link is on Audacity website so

[03:01] we can trust this link so I click on

[03:04] that and I reach on this page and my

[03:06] operating system is Windows so I am

[03:08] using audacity on PC so I click on this

[03:12] 64bit windows and then you save this on

[03:15] any convenient location so I'm saving

[03:18] this on my desktop and it will just take

[03:21] few seconds and now I get this file on

[03:24] my desktop I click on that accept the

[03:27] licensing terms click next and click

[03:30] install and finally finish installation

[03:33] and after the installation when I open

[03:35] my Odes and I try to put my

[03:42] video let us close this as you can see

[03:45] that I directly got the audio extracted

[03:48] from my video and if you don't see this

[03:51] and you have some problem I'm going to

[03:53] show you how you can solve that problem

[03:55] because some users they will see that

[03:58] FFM Peg is is still not found so I'm

[04:01] going to show you in a minute but in my

[04:03] case it automatically detected this and

[04:05] now what I can do is I got this audio

[04:08] from my video and I want to save this as

[04:11] an MP3 file as an audio file to do that

[04:14] I click on file and then I click on

[04:18] export and on the right hand side I can

[04:20] export as MP3 file web file WAV file or

[04:24] I can also export audio or I can also

[04:27] export audio so these are the three

[04:29] three different options so I want to

[04:31] export as an MP3 file so I click on that

[04:36] and I can change the name if I want

[04:38] otherwise it will be saved in the same

[04:39] folder with MP3 file simply click save

[04:43] and click okay and you will see this

[04:45] progress bar and within few second the

[04:48] audio file will be saved so let us see

[04:50] if you don't get this audio straight

[04:53] away and you see the same message that

[04:56] we got in the beginning of this video so

[04:58] let me open this again as you can see

[05:00] that in my case the library is there and

[05:04] there is a library version but if you

[05:06] see any error here Library could not be

[05:08] found then now you have to click on

[05:11] locate previously we clicked on download

[05:13] now we click on locate you will not see

[05:16] this message because it says that you

[05:18] want to locate again so I click yes and

[05:21] you will only see this area where you

[05:23] can browse so you click on browse the

[05:27] file will be in your program files

[05:30] directory which is normally in C

[05:33] directory and in this program files

[05:35] directory you will look for a folder FFM

[05:38] Peg for audacity so this is the folder

[05:41] you click on that and as you can see

[05:43] here that by default that the software

[05:46] is expecting this type of file and we

[05:49] have this file in this folder you click

[05:52] on that and you click on open and this

[05:55] will solve your problem I'm going to

[05:57] cancel this now what if this also does

[05:59] not solve your problem then remember one

[06:02] thing that whenever you are using any

[06:04] open- Source software and you are facing

[06:06] some errors which you should not face

[06:09] the best solution is that you reinstall

[06:12] the software so when the first time I Ed

[06:15] this Library it did not work even after

[06:18] I located properly I downloaded

[06:20] installed everything but then I

[06:22] uninstalled audacity and reinstalled and

[06:25] it worked it automatically detected my

[06:28] FFM Peg and and everything worked fine

[06:31] so this is how you can install this

[06:33] library and now you simply drag and drop

[06:35] and get the audio from a video now we

[06:38] come to the important question what are

[06:40] some of the reasons why you would like

[06:43] to extract audio from a video I have

[06:46] listed this on this screen you can pause

[06:48] the video and you can note but basically

[06:51] sometimes you only want audio not the

[06:54] video for example you want to create a

[06:56] podcast from any video because nowadays

[06:58] many YouTube they are making podcast

[07:01] from their videos as well and putting on

[07:03] various platforms to get some extra

[07:05] income sometimes you want to get the

[07:07] transcript of the video and sometimes

[07:10] you want to translate that transcript so

[07:12] you need to get the transcript first in

[07:14] your original language then you

[07:16] translate it into any other language so

[07:18] you can translate the text obtained from

[07:20] the audio and sometimes you want to get

[07:23] the subtitles so there is a difference

[07:25] between a simple transcript and the

[07:27] subtitle and the difference is that in

[07:29] subtitles you also get the time stamp

[07:32] when you speak something so why we want

[07:35] subtitles because in order to extend

[07:38] your audience for example if you are a

[07:40] YouTuber like myself I sometimes upload

[07:43] subtitles in more than one languages on

[07:46] my videos now the final and most

[07:48] important reason that I am considering

[07:50] right now about my videos is that I want

[07:53] to dub my videos in other languages to

[07:56] grow my audience and if you want to dub

[07:58] then you first have to get the subtitles

[08:00] in original language in my case it is

[08:02] English then I will translate that to

[08:06] any other language for example Hindi and

[08:08] then I will use a text to speech

[08:11] software to convert that subtitle to

[08:14] audio and then I will put that audio

[08:17] track in my video and that can be done

[08:19] in any video editing software so I will

[08:22] be making separate videos for these

[08:24] steps if you are interested in how to

[08:26] dub your videos or how to translate your

[08:29] transcript and what are the issues

[08:31] involved in that then you should

[08:33] subscribe to my channel and wait for the

[08:35] next videos we are expecting that soon

[08:37] YouTube will allow us to add more than

[08:40] one audio tracks to our videos and when

[08:43] someone from some other language will

[08:45] try to watch our video the audio of the

[08:48] video will be played in that particular

[08:50] language and that would be fantastic and

[08:53] that will help us grow our audience and

[08:55] we are looking forward to YouTube to

[08:57] allow us to add more than one audio

[09:00] tracks to our videos with this I end

[09:02] this video thanks for watching and see

[09:04] you next time
