Step $4$: When you are satisfied with the recording, select and save it by going to Select $->$ All, then

going to File $->$ Export Audio. Make the following settings in the Export Audio dialogue box:

$$ Export Range $=$ Current selection

$$ Channels $=$ Mono

$$ Sample Rate $=8000$ Hz $($original recording will be resampled at $8000$ Hz$)$

$$ Encoding $=$ Unsigned $8-$bit PCM $($PCM means Pulse$-$Code Modulation$).$

$$ Format $=$ WAV $($Microsoft$)$

$$ Folder: choose a suitable storage location $($folder$)$ for the audio file

$$ File Name: name your files in the format LastNameY

$\_$

FkHz$\_$Dbits. Where LastName is your

last name, Y is the initial of your first name, F is the sampling frequency in kHz $($F $=8$ for the

current selection, and D is the bit depth per channel $($D $=8$ for the current selection$).$

Next, export the same recording using a bit depth of $16$ bits by setting the Encoding to Signed $16-$bit

PCM and name the file according to the given format. Recall that WAV files contain uncompressed

encoded audio samples
