the first thing I want you to do
is I want you to open up your browser
and go to www
dot all this tight-knit and as you can
see here we see the link
for a all this audio let me tell you a
little bit about
all this audio all this audio is a
ceasar
audio library that enable C sharp and BB
dot that developers
to ed audio capabilities to different
died
Net Applications the library allows
C sharp and VB dotnet developers to
create
applications that play including Mexico
record in convert uncompressed or
compressed audio data
you can encode and decode dialogic
dot Boix format data
the first thing that we want to do is we
want to send reference
to are all those done audio component
library
that we've downloaded I've already done
so well go hidden
walk you through that process we
basically you're going to learn to stop
location where we've downloaded
the oldest on audio component library
and we've already extracted the files
to the desktop open here
the oldest on audio folder go to the bin
folder
and choose the oldest auto deal DLL
game and so we have our reference n
now let's take a look at the form
that we have set up to convert weighty
to mp3 files
we have
to labels two text boxes
and three buttons Liz click on our first
button
k im here our first button
is the but an audio file one click event
which basically lows the audiophile
K in the method load audio file one
uses an open file dialog opens up the
file dialog showing in
and we choose the audiophile
that we want to convert from away
to an mp3 file
and in this case we're going to choose
away file
school backed
second button is set the output file
name
goes to this method which basically
takes the folder
browser dialog and it shows the dialogue
to the user
were basically taking
the information from
the folder browser dialog we're gonna
take that
path we're going to take a system that I
feel
that hath and get the file name without
the extension
in this case is going to be dot wave
willing to strip
the pair have the extension
and then we're gonna and are mp3 or dot
mp3
with me and a line here so you can see
this
with and underscore converted to mp3
and we're gonna plays dead in art txt
output file name
got tax property thats this
text box here okay now
let's get to the media the application
which is converted to mp3
which is this button hearings double
click on it to go the
its click event here we want to go to
the converter waved to you mp3
method now in this method
on the first line
we're gonna take a system that I i all
FileStream
called old file1 and we're gonna
open up the txt audio one
takes property in remember art txt
ordeal one text box contains
the path to the wave file that we're
going to convert
the next line
we're gonna taken all those done audio
wave reader
and we're going to set that instance
name to
hallway for reader 1 and we're gonna
read
the FileStream K
all file one next line
willie setup pointer to the original
format
above always reader one worried that
format
place that value
into the original audio format our next
line
gonna set up a byte array called wave
reader data
and we're going to use the always reader
one object henry the data
passing those bites into the wave reader
data
by torie her next line
we're going to close the all wave reader
object
next
we're gonna send a pointer call
mp3 format to the
compatibility format based on the
original audio format
which is a wave file and we're going to
get the compatibility format I'll the
mp3 layer so we're going to use
and always done audio audio compression
manager
died kid compatible format method
passing in the original format pointer
and
setting that up with an mp3
format our next line
we're going to take a byte array
called data and we're going to use in
all those dot audio
all yield compression manager
to convert from the
original audio format the way format to
the new
mp3 format using
the whole wave reader data by terrain
on the next line
we're gonna take a system that I all
by Mary writer called all
binary writer and we're gonna set up
a by Mary writer to
right to the file
there were gonna create using a system
die all file
create method using the
txt output file name
which is our output file name using that
text property of the text box
we populated once we used
the second ellipse button to choose the
destination path
are output file our next line
we're using be all binary writer
object to write the data
King which we populated
with the byte array okay
remember we use the all was not only
your audio compression manager
to convert method and we populated that
data byte array we're going to use
the byte array with a right there now
using the all binary writer dot right
method
in our last line we're simply gonna
close the old by Mary writer
up to and at this point we have
successfully converted
away file to me.mp3
file now let's see our application in
action
let's fire up are debugger
and let's go ahead and minimize Visual
Studio
so here's our form
and lets choose
a wave file and I have a wave file
lets jus then night sound sample
furs let's listen to
the night sound sample us
came
in so we're gonna set this as our
input file now we're gonna choose our
destination
we discuss it to be that this Tom
and as you notice
we've taken the
input file which is night sound sampled
on wave
we've set our output file name tonight
sound sample
underscore converted to died mp3
let's click on the convert
to the mp3 button and we're gonna get
the all those done audio
trial version reminder dialog box
just reminding is that we need to
purchase
a valid copy up the all his daughter
audio
component library click OK
and the process
is complete let's listen to our newly
converted
wave to mp3 file
us
us excellent this is Michael comes in
with play a be incorporated
stay tuned for the last video this
series
where I'm going to show you how to
combine
all the applications in this series
in 21 application where you want to
joining to audio files you want to
convert
mp3 to wave format you gonna convert
waved to mp3 all
in one application so stay tune
for that next video you don't want to
miss it so head on over to WWW dot
all those dotnet download
the all his dad audio component library
and I think you be very satisfied with
how it performs
what it enables you to do with audio
an you be willing implement this
into your next all your project this is
Michael Thompson will play here
incorporated
hope you found this tutorial helpful
have agreed a
in all by the way leave me a comment
