CDex and Audacity incompaible

T

t-4-2

It was suggested to me that I should look for answer in Audacity forum. But
the forum is " locked ". I can't post . Yes, I am a member.
So, I am hoping for a resolution here.
I use audacity to combine 2 songs into one sound track. I went well. I can
either export the sound track as a MP3 or Wav. But, the file size of Wav
ballooned from say 2.25 MB ( 2 MP3s combined ) to 13 MB.
So, I tried to use Cdex to do the trick of disguising the new sound track as
Wav. It won't take it. It froze.
Is there any way I can convert the newly Audacity created sound track into
WAV and still maintain a reasonable file size ?

WAV is uncompressed audio
you could drop the quality or change it to mono sound.
Im not sure if powerpoint supports WMA but it might be worth you haveing a
look at that format

No, those MP3s are not CDex reproductions.
CDex takes any MP3 downloaded from web sites and turns them into WAV, no
problem. It just refuses to accept the Audacity produced sound tracks.
I had 2 different MP3. Same result.

I don't have anything in WMA format for the moment.
Will look into that this one is not resolved. Thank you.

PowerPoint will works well with WMA files, but it cannot embed them; it only
links to them. From your earlier discussion, I believe the reason you want
to go with WAV was to get them embedded in your PowerPoint file.
Unfortunately, WMA won't help with that.

For the benefit of PP ' newbies ' users, the methods do work :
To combines 2 songs into one sound track ... use Audacity.
To disguise the sound track as WAV ( put a RIFF header to a MP3 ) ...... use
CDex.
Now you can insert the new 2-songs WAV to your PowerPoint presentation.
NOTE: I only combined 2 songs. Not sure about 3 or more.

It will work with as many songs as you want. The embedding will only go to
what you have set with the max being 50000kb.

The reason the size of the WAV ballooned when you saved the combined file is
your Audacity settings.

You can halve the size of your WAV by changing from Stereo to Mono.

You can also change the bit-depth and sampling rate. Sometimes these changes
sound fine on a file, sometimes they don't. You just have to experiment.

Bit depth: http://wiki.audacityteam.org/index.php?title=Bit_Depth says to
change on Quality tab of Preferences.

Sample rate:
http://www.jakeludington.com/audacity/20051121_changing_audio_sample_rate_in_audacity.html
and http://forum.videohelp.com/topic292388.html -- change Project Rate in
lowe left corner. I believe you can change the default sample rate in the
Quality tab in Preferences.
http://audacity.sourceforge.net/onlinehelp-1.2/prefs.htm

Stereo to mono: http://www.richardcravy.com/?p=39 Use the dropdown menu on
the left (shown in the link -- just click one of the images) and select
Mono. You don't have to split the tracks here, because you're working with
music, so it would be better to combine them, I think.

Thank you for all those links.
By the way, 1/2 the size of 53.3 MB is still 26+ MB. Far cry from 4.83 MB
using CDex.

Yes, but that's an MP3 with RIFF WAV headers. Different animal.

Good question. I don't really know the details.

One is an actual WAV file format. The other is an MP3 format with WAV
headers. I don't really know other than that. (I'm looking forward to
finding out the answer from others here, though!)

One thing I do know is that the WAVs created with CDex don't work on all
machines. I guess it's probably something to do with the file format / file
header mixmatch. (Then again, sometimes WAVs and MP3s won't play on some
machines, so it's not like they're infallible or anything.)
