Easiest/Fastest Audio Converter for Windows | Full Guide | FFMPEG Crash Course

what's up guys my name is techno boo here for troubleshooting today I've got a really simple video for you that isn't nonetheless incredibly important and useful food and not basically if you work with video audio if you created music if you put music from your PC onto an mp3 player your phone or if you just generally need to convert music you're probably used to going onto Google going into a free website uploading file downloading it putting in a ton of effort for a little to no return while in fact it's incredibly simple to change music from one format to another lower the quality decrease the file size etc etc without having to do any downloads past the initial one what am I talking about well today I'm gonna be talking about ffmpeg which I've covered in a previous video of mine on how to install it and that'll be linked in the description down below assuming that you already have it installed if you were to hit start R type in CMD enter and then type in ffmpeg hit enter you'd see this information pop up here instead of an area that looks like this saying it's not a recognized command as long as you see all this information up here or something similar to it that means you have ffmpeg is successfully installed now what exactly is ffmpeg well it's great for converting your video and audio from one format to another changing and adding effect filters etc etc but today I'm gonna be working with this little mp3 file inside of this folder over here as you can see it plays perfectly normally it's a three minute song that is around abouts of five megabytes it's Audion mp3 however I'm gonna go ahead and change this into a different format such as AAC for example which is a popular format when it's combined with an mp4 video that'll work properly if you would upload its youtube it usually has h.264 normal video and then AAC audio instead of mp3 but that's just one of the many many examples you can convert to practically any kind of container whether it's mp3 wav or flek AAC AIFF etc etc there's basically an infinite number of these containers that you can convert to and from so the simplest way to do this is to slowly double click on the file you want to go ahead and convert control a we'll see control a selects everything control Z copies it as long as you see done mp3 afterwards or something similar then this is going to work properly if you don't see file extensions at the very top good of you and make sure the file name extensions checkbox is ticked then you should see the name of your song WAV mp3 etc etc slightly double click ctrl a ctrl C then at the very top where it says the folder name we'll click there and we'll type in CMD and hit enter non side of this new window a simply type ffmpeg space - I for input space quotation mark ctrl V to paste quotation mark so now we've said that ffmpeg this is the input file that we'd like to convert space inverted commas and this is where the name of your output file goes you could name it anything dot WAV AAC etc etc but usually what I do is I paste in the previous name I press backspace to get rid of the existing extension and I'll type in another one that I wanted to go to so I'll change this to a wave WAV and close the quotation marks then hit enter and it will begin that transcoding now obviously wave is a much less compressed of format than mp3 so as you can see the file size went from 4 megabytes or just under 5 to about 31 if we want to double click on the wave click through it you'd see it functions exactly the same as the mp3 above it it's just now that it's in a less compressed format which is much more compatible with a lot more devices and of course the inverse is true if you picked a more compressed format you can of course converted to that or from that so if I were to take this giant wave over here tab back into the command prompt window ffmpeg space hyphen i space quotation mark paste in the waves name close quotation marks space do it again I'll take out the wave and type in AAC closing quotation marks enter it'll go ahead and compress it from a wave into an AAC file which is 2 megabytes or just under 3 compared to the original file of 5 megabytes and the uncompressed WAV of 31 megabytes so of course compressing your mp3s into a ACS would be more space efficient but it may change the see ever so slightly because the way that they are encoded however this is by far the easiest way to convert files on your local PC with no extra downloads noise or software and the fact you don't even need to go ahead and open up this command from window you can even type the command in it straight up here so ffmpeg space - I quotation mark pasted on the name quotation mark quotation mark again pasted in I'll change the wave to say an mp4 which will have no video it'll only have audio of it enter it'll go ahead and convert and there we have a dot mp4 as you can see it's round about the same 2.8 megabytes that's because ffmpeg has changed it from an mp3 to AAC audio and then put it inside of an mp4 if I double click the video should be black or there should be no video at all and it will just to beat the audio and it's working perfectly as it expect now of course that being said this is an incredibly powerful piece of software and we can get a lot more in depth but before we get there you just need to understand that just because the file size is bigger it doesn't necessarily mean that the quality is better you cannot get more quality out of a file you can only get less or equal quality out of a file that's why this mp3 of 5 megabytes is probably just the same as this AAC of 2.8 megabytes but this away file over here that's 30 megabytes is definitely not any better than the mp3 file over here you have data and you can only remove it or copy it you can't create data just by guessing that being said let's go ahead and investigate some of the other settings we have so you want to change bitrate how exactly do we do that if we were to go ahead and give our question a google ffmpeg audio bitrate clicking the first link takes us to the ffmpeg wiki for AAC let's say we want to go to mp3 if you can simply type it in at the very top and replace it then we have this over here so as you can see mp3 uses something called VBR variable bitrate there is also CBR for constant bitrate however this is a bit more in-depth basically setting a cue a which is from quality audio to one of these numbers over here will give us plus minus a great range of 45 to 85 kilobits per second or 320 etc etc and this is usually what we'll be using so I only need to do is have a look at the very top over here at the sample so we'll copy - codec a this name and we'll copy all the way to cue scale a copy it over there will tab into our CMD window go back to between these two and paste it in space face and we'll go back one just so we can enter our text in here so let's say I want the absolute worst quality to show the biggest difference 45 to 85 kilobits per second I'll use it QA of the 9 so you can type it in as such codec a Lib mp3 lame which is the standard mp3 codec q scale a 9 now of course they also say that you can use Q : a so I'll go ahead and use that just because it's a little bit easier so if we go ahead and hit enter it'll go ahead and convert our input into our output and our specified quantity some looking back in the folder if we were to get rid of the rest of these files you'll see that we went from just over 5 megabytes to 2.2 megabytes and b3 audio if we open it up it does sound quite a bit more muted and not as good and that's probably because we lowered the bitrate it's just under half of the file size mean that we've given up a lot of quality but this conversion has actually worked if I were to open up a tool such as media info we can get some more detailed descriptions on this so I'm for the first file the input file you can see where Rhonda butts 217 at kilobits per second if we go ahead and check our output file you can see where Rhonda bots seventy eight point five kilobits per second which is right at the upper end of the 45 to 85 a scale that they show at the very bottom over here of course if you don't want to use VBR you can use - a BA and put in your own kilobits settings but of course this is more for you to discover how exactly would you do that well you do it very similarly I'll just clear the screen with the CLS and hit up twice to go to our previous command and I'll change QA to be a for betrayed audio and I'll set it to say 56 K meaning 56 kilobits per se and I'll hit enter when it asks me if I want to overwrite the output file I'll type in Y and hit enter once it's done you should see the output file is a little bit smaller now it's now 1.7 megabytes instead of 2.2 the quality has also drastically decreased however we've successfully lowered the bitrate of our audio either way that's probably as much as you need to know there's a lot more to this tool but it's way too in-depth to go to in one video so I'll leave it here as is if you'd like to see more on this topic make sure to comment down below and leave a like on it thank you for watching - Ben take number here for troubleshoot I hope this video helped you out and I'll see you all next time ciao
