[0:00] welcome in a previous video I talked
[0:02] about ripping CDs to lossless audio
[0:05] using Windows Media Player on Windows 10
[0:08] in this video I'm going to be talking
[0:09] about using a shell script to convert
[0:11] lossless audio to mp3 format I did a
[0:15] previous video to do the same thing with
[0:16] AAC and this is going to be very similar
[0:18] to that video so I have the music folder
[0:23] on this computer with two albums in here
[0:25] it has lossless audio on it and I'm
[0:30] going to go and and you need to install
[0:33] Windows services for Linux I have a
[0:35] video on that I'll put that in the
[0:36] description once you have that installed
[0:38] you can execute a typing bash and this
[0:40] will bring a shell up and we'll need the
[0:44] ffmpeg software and I've done some
[0:46] videos on that there's a couple
[0:48] different ways to install it for this
[0:50] video you need to install it from within
[0:51] the windows services for Linux so you
[0:55] would type sudo space app space install
[0:59] space ffmpeg we'll hit enter it'll ask
[1:02] for a password and I already have
[1:07] installed but it would install here next
[1:10] we'll navigate to the music folder or
[1:12] the my home directory so I'll type CD
[1:14] space dot forward slash dot forward
[1:17] slash and that'll take me down to
[1:19] directories then I'll type CD space
[1:22] users with a capital u and then my
[1:24] username which is Rick if I look in here
[1:28] we'll see I have a music directory and
[1:30] that has the lossless audio in it I can
[1:33] type in mkdir space music underscore mp3
[1:39] and this will create an mp3 directory
[1:42] that we can store the mp3s in so what
[1:45] this will do is this will retain the
[1:46] lossless audio and it will create a new
[1:48] folder with just the mp3's in it next we
[1:51] can type in nano space convert to mp3
[1:59] dot Sh and this doesn't have to be exact
[2:02] but I'll do that that'll open up a text
[2:04] editor go over to my website here and
[2:08] I'll select all this code
[2:13] I'll right-click and say copy and then I
[2:17] will right-click in my editor and it
[2:18] will paste that in there well look
[2:20] through this real quick so this bin bash
[2:23] just means it's a shell script the set e
[2:26] is so when you hit ctrl C it will kill
[2:29] the whole script otherwise it will just
[2:31] kill the ffmpeg process that's running
[2:33] and this just talks about usage here
[2:36] these few lines are cleaning up the
[2:39] directories you supply it to make sure
[2:40] that the the trailing slashes are fixed
[2:44] and the full path is used this fine
[2:47] command finds all the slacker
[2:50] m4a so this would be for flak and
[2:52] lossless audio files and it passes those
[2:55] to a loop so this loop will split apart
[3:00] the name and directory and it will
[3:03] create a new directory in the new folder
[3:05] and it will create a new file name and
[3:08] then it will look to see if the file has
[3:09] been created before and if it hasn't it
[3:12] will convert it using this ffmpeg script
[3:15] so you have ffmpeg here high banner will
[3:18] just hide like version information and
[3:20] such - I will be the input so this is
[3:23] the original file - C : a is the audio
[3:27] codec and it will use lib mp3 lame and
[3:30] then - Q : a is the quality so we're
[3:33] going with - so it goes the lower
[3:38] numbers are better quality so if you
[3:39] want to one or zero you could
[3:40] potentially get better quality but this
[3:42] is considered very good quality so it's
[3:44] probably not worth going lower on this
[3:45] and this is variable bitrate - and you
[3:49] can change these up if you want some
[3:51] kind of different that format and then
[3:52] we have the new file name here and this
[3:54] is in quotes in case our spaces and then
[3:57] we have less than slash dev slash null
[4:00] and this keeps a standard input from
[4:02] getting into ffmpeg and causing problems
[4:04] so now I'll type ctrl o to save this out
[4:08] and then ctrl X to exit and then before
[4:11] we can run the script we need to type
[4:12] chmod space plus x space and then
[4:17] convert to mp3 dot Sh so this will make
[4:21] it executable so now I should be able to
[4:23] type dot slash
[4:25] convert to mp3 Sh and you'll see it's
[4:28] asking it's telling us how to use this
[4:32] so to use it I'll type dot slash convert
[4:35] to mp3 Sh I'll type the source directory
[4:38] which was music and then the destination
[4:41] directory which was music underscore mp3
[4:43] and it doesn't matter if you have the
[4:45] trailing slash or not so I'll hit enter
[4:47] here and now it will start encoding this
[4:50] to mp3 so if we click on our File
[4:55] Explorer I'll click on my home directory
[4:59] if we look in music mp3 you'll see we
[5:02] have the taylor swift folder if we click
[5:04] on it you'll see reputation and then in
[5:07] here it's converting the files to mp3 so
[5:09] it will recreate the file structure as
[5:12] it encodes so if you hit ctrl C while
[5:18] this is running it will stop the
[5:24] execution
[5:25] so then you'll want to go into your
[5:28] music and find the last file it was
[5:35] encoding looks like it was called don't
[5:38] blame me and we'll click on this and
[5:42] we'll delete it so this script if we run
[5:47] it again it will start off where it was
[5:50] last time but that when you stop it in
[5:54] the middle of encoding a song it'll
[5:55] screw up that song so we delete that one
[5:57] song we run it and it will pick up where
[5:59] it left off so what you could do with
[6:03] this know is you'll have this music mp3
[6:05] folder you could copy this over to a
[6:08] thumb drive to stick in your car like
[6:11] USB so you can play it off your car
[6:12] stereo you can stick it in an audio
[6:14] receiver the back of the TV you could
[6:17] move it to an mp3 player you can do it
[6:19] with it whatever you want and then you
[6:22] could take your lossless audio if you
[6:24] want and you could move it to a USB
[6:25] Drive a thumb drive a large SD card and
[6:28] take it off your computer and then
[6:30] someday if you want to reload to a
[6:32] different format you could stick it back
[6:33] in and then run a script like this again
[6:35] like if you want to go with a cc or
[6:37] change the quality level or
[6:38] whatever or if you had a small mp3
[6:42] player you want to take jogging with you
[6:44] every day you could encode to a smaller
[6:46] format so maybe the quality isn't as
[6:48] good but you could put more songs on
[6:50] your player by running this script so so
[6:54] that's the basics of using the bash
[6:57] script to convert lossless audio to mp3
