Power Point sound

Just this past year when I record sound into my Power Point slide show, the sound has a scratchy background. The sound from my speakers is fine. The sound from last years slide showa are fine. It's just what I record now, plays back with a hiss behind the music. I started with Office 95 & the problem started this year. Upgraded to Office 2003 but still have the same problem. Hope you can help.

Hello apat33,

idea but have you tried another microphone?, i realize that you said the sound from the speakers is fine but did you use the windows recorder utility to see if that comes with background noise too?

hope this helps a bit

Hi,

Please make sure that the quality of the sound recording via PP is "CD quality".

It is in the 1st window which opens when you start the recoding.

Good luck

Don't understand how to find "CD quality" I click on the little speaker in the 1st window but find no reference to CD quality. You could be on to something though. I now have all my music stored in I Tunes, could this be the problem? Though once again, playing through the computer speakers, the sound is fine.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

What do you mean in"when I record sound into my Power Point slide show" can you specify exactly what you do?

Try using WAV format in external music files.

In Power Point, on a slide in my show, I open the insert tab to Movies & sounds, open Record sound. Start song in I-Tunes, switch back to PP, click the red button on record sound, the second counter shows it is recording. After, I name the song & it is installed in the sound box, shown in the slide transition section. As I said I have performed this task in the past with no problem. It's just been this past year as I try to build a slide show. I have no idea on how to get a WAV format. My I- Tunes are in ACC & MPEG formats.

So I understand that you record into PP from the speakers.
This way you may record background sound as well.
The best way as said in http://www.rdpslides.com/pptfaq/FAQ00685.htm
is
"To convert to an MP3 you will have to save the M4P music file(s) to a CD and then "rip" them back to your hard disk as MP3s"

i.e. burn a CD in I-tunes and then rip it to MP3  or wav using some other software like windows media player. Use PP to link to the MP3 file.

If you like your old way use "sideshow narration..." in the "sideshow" menu in PP for recording there you can select the quality.

Andy, I am not ashamed to admit that I'm not totally clued up on newfangled iPod's and such, but my understanding is that i-Tunes is a Windows Application that allows you to import, organise, download, store and maintain your audio files.

I assume it can also sync with your iPod, in which case I have to ask whether the music file you start playing in i-Tunes when you then start the recorder in PowerPoint is located on your iPod, or whether it is saved as a local file on your hard drive.

You say that, in the past inserting audio content into slideshows has been problem-free, but were you using i-Tunes and/or your iPod when you did this before?

There is something that perhaps you aren't aware of:

There is an option in PowerPoint (Tools > Options > "General" tab) that decides when PowerPoint should embed the sound file into the presentation file, or leave it as an external resource and the object (eg. speaker icon) in the presentation just acts as a link to the file.

Obviously you don't want the final presentation file to be so huge a file size that it can't be shared by email, etc, so this decision is set as the file size of the sound file.  I can't recall what the default setting is, because I increased it a bit, but I think it is somewhere around 50KB.  If the sound file is greater in size than the limitation set in your PP user options, then the sound file remains tied to it with this link.

If you ever move this PPT file to another folder, or burn it to CD, without moving the linked sound file (keeping the relative location of the files), then the sound file won't be able to play.  By "relative location", what I mean is that it's like using Internet Explorer to "Save As" an html web page, and it creates a parallel folder into which the image and other files are saved.  The code in the html web page loads these files from that folder using "relative" links, ie. it doesn't specify the full path to it, only its whereabouts in relation to the html page.

What I am wondering is if the following possibilities are happening:

1. When the audio content is played back in the slideshow, it is actually playing from your iPod
OR
2. The powerpoint player controls are having to load and play the file through i-Tunes rather than directly from its own embedded object or from a linked external file.

Right-Click on the speaker icon in your *.ppt presentation (ie. in edit mode) and choose "Edit Sound Object".
What does it show at the bottom of that dialog right above the OK and Cancel buttons.
If it says "File: [Contained in presentation]", then it's embedded.
If it says "File: C:\path_to_sound_file\..\..\filename.ext", then it's linked as an external file.
If the path shows with your i-Pod's drive letter, then it's linking it to that device.

I'm not saying that I think playback in a slideshow from an iPod would necessarily degrade audio quality, but ideally you should be keeping linked files on your hard drive and in a folder in the same directory as your slideshow file so that you can move them as one unit.  It is remotely possible, however, that playback from an external physical device could degrade the sound if this is what is happening.

I go with the above recommendations.  Convert the sound file to WAV or MP3 format, and try and insert that "from file" rather than recording it from i-Tunes playback.

Another important consideration is that the playback through your sound card is probably using DirectX components like DirectSound.
Run DXDIAG.EXE from the Start Menu's "Run" field, and run the DirectSound tests from the "Sound" tab.
Does it sound scratchy on any of the test modes?

Copy the ppt presentation to someone else's computer and test it to see if the audio playback is affected in the same way.
If not, then the problem is definitely with your system and not powerpoint in general.

Well fellows, I'm struggling along with your suggestions. My head is swimming. I have got this far, Using the "record from file" as you both suggested, I get it to play & the sound is just fine, no background. So that seems to eliminate computer sound problems. This method won't work for me, as I like to send the slide shows out to family on a CD. As you mentioned Billdl, the imbedded music has to be attached. Also I don't record from my I-Pod but from I-Tunes which is on my hard drive & I did use I-Tunes in my previous sucessful records. I tried to burn to a CD then rip into Media player, had no luck. Did get a MP3 to play in Winamp but it would not record into the slide show. Shows up in the sound box, I select it, start the show, no sound, even though this was the same song via winamp that would work "record from file" I also have new speakers. I was hoping that would solve the problem. Yes when I put the slide show on a CD & play it on another computer the background hiss is still there. Finally, I-Tunes will let you convert I-Tunes ACC files to MP3. I did that & it shows as a MPEG file. It plays fine on the computer but just like the winamp, I get no sound out of the slide show

Try using WAV format.
Maybe there is some problem with MP3 decoders on your computer.

Maybe this will intrest you
http://www.techsmith.com/download/camtasiatrial.asp
this software has a plugin for PP which will turn your presntion into a movie AVI or FLASH.
you can then add the mp3 to the movie.

If you could give us a rough indication of what content your distributed presentations on CD usually contain, we will probably be able to suggest alternative approaches other than using powerpoint.  I realise that doesn't answer the question, but an alternative method might turn out less frustrating in the long run.

What I am driving at is whether your presentations are family photo's presented with background music that is really more ambient than accurately synchronised to the image sequence. If so, then what I use is a simple and tiny standalone executable that takes its instructions from an *.INI file in the same directory, and runs entirely from its own resources on a CD.  It downloads with a fully commented .INI file so that you can tailor it to suit, and one of the options is to have it play MP3's in the background as it steps through images.

Without a doubt, you can create highly polished presentations with some stunning transitional effects, etc in powerpoint, but I like the sheer simplicity of the above freeware program.

Thanks for both your replys. I downloaded the 30 day trial, Camtasia. Really don't want to spend hundreds of $$$, when I have a $$$ program I'm trying to get to work.
Billdl, I use PP for family & travel photos that I like to set to music. I will check out the downloads you sent.
