MS Office Forum / General PowerPoint Questions / July 2009CDex and Audacity incompaible
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 ? t-4-2 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 > It was suggested to me that I should look for answer in Audacity forum. But > the forum is " locked ".

[quoted text clipped - 16 lines] >> WAV and still maintain a reasonable file size ? >> t-4-2 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. --David On 7/14/09 6:42 AM, in article eLraI$GBKHA.3368@TK2MSFTNGP02.phx.gbl, > I don't have anything in WMA format for the moment. > Will look into that this one is not resolved.

Marcovitz Author of _Powerful PowerPoint for Educators_ http://www.PowerfulPowerPoint.com/ Microsoft PowerPoint MVP Associate Professor, Loyola University Maryland David I can't repro this here. Two mp3's combined in Audacity seem to work fine with Cdex. Can both of the original mp3's be "Cdex'd"??

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. t-4-2 > David > I can't repro this here.

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.

[quoted text clipped - 7 lines] > WAV and still maintain a reasonable file size ? > t-4-2 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_aud acity.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.

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.)
