Default Can PowerPoint play a random sound file from a specified directory on slides I designate?

Hey all, first post here! I use PowerPoint as part of my work and have a mountain of advanced things I'd like it to do, but don't know how. So I figured I'd start with this one and see how it goes!

Basically, I have a directory full of music clips. For certain slides in my show, I'd like PowerPoint to choose one of those music clips at random, start playing it automatically, and end it at the end of that slide. (If it could fade it out instead of just cutting off abruptly that would be even better!) What I'm going for is an effect kind of like a sports game where they have a song kick in at every break in the action. Also, it would be really cool if it could remove a song from the random selection pool after it's used so there's no repeats.

Is there any way to do this? Thanks!

Sounds like it would need to be done with a VBA script by putting all of the songfile names into a collection. Have a random function choose one of the songs and then have that item deleted from the collection after it has been played. As far as fading them and other stuff I would need to do some research on it to see how that is done.

You mention that you have a mountain of things you want to do with VBA most likely being a large part of accomplishing these advanced things do you want to go down this road. I can get you started with a code but will need the names of sound files. It will take some time to write out and I may not be able to effectively get to it till the weekend. Someone like John Wilson could probably bust it out in 30 minutes right away. lol Im not that good but I am happy to help. If anybody can do it faster go for it like I said I may not be able to get to it until the weekend.

Let me know.

Thanks

Wow! Yeah, if you're willing to do that, I can certainly wait until after the weekend. Thanks so much!

The names of the sound files are going to be: HYPE001.wav through HYPE100.wav; I'm going to be making them myself using a sound editor so it's easy to just make the filename whatever I like.

Ok this wasnt as hard as I thought. There are a couple of ways to go about using the code that I am going to provide to you. I am not sure how your presentation is set or how you plan to use this code so I am giving you 3 different versions.

First off the fading of audio files is not possible in VBA unless you are fading the very end of the song. Seeing how you will be advancing the slide at a random time this is not possible. There are however third party add ons that claim they can do this.
http://www.officeoneonline.com/volctrl/volctrl.html
Is one that has several sources claiming it can do fades but I have not tried it. It has a 30 day free trial and then after that it is 20 bucks.

As far as the rest this can all be done for free with VBA.

The first set of code is 2 separate procedures the reason there are 2 procedures is because you may need to be able to call one of the functions again. I dont know since I am not aware of how your presentation is set up.

This code block uses the very last slide in the presentation to store all of the audio names. In the event that you need to keep updating this. Maybe you want to allow the user to replay the game and still prevent songs from being repeated. So make sure to insert a blank slide at the end of the presentation.

For all of the code blocks you need to set the directory which is where the sound files are coming from and you need to set all of the slides that you want a file applied to.

Code:
Option Explicit
Public pst As Presentation, DataSlide As Slide

Sub ResetSoundFileString()
  'Resest the sound file string with all sound file names
  Dim x As Integer, SoundString As String, FileName As String
  Dim StrNum As Integer, DataBox As Shape, shp As Shape
  Dim pst As Presentation, DataSlide As Slide
  
  Set pst = ActivePresentation
  Set DataSlide = pst.Slides(pst.Slides.Count)
  
  For x = 1 To 100
    StrNum = x
    Select Case StrNum
      Case 0 To 9: FileName = "HYPE00" & x & ".wav"
      Case 10 To 99: FileName = "HYPE0" & x & ".wav"
      Case 100: FileName = "HYPE" & x & ".wav"
    End Select
    SoundString = SoundString & FileName & "|"
    FileName = ""
  Next x
  SoundString = Mid(SoundString, 1, Len(SoundString) - 1)
  For Each shp In DataSlide.Shapes
    shp.Delete
  Next shp
  Set DataBox = DataSlide.Shapes.AddTextbox(msoTextOrientationHorizontal, 94.125, 61.875, 383.125, 140.875)
  With DataBox.TextFrame.TextRange
    .Font.Size = 7
    .Characters = SoundString
    .Characters.Font.Size = 7
  End With
  
End Sub


Sub ChooseRandomSong()
  'Takes the string out of databox to use for a trigger
  'Then deletes it out
  Dim x As Integer, SoundString As String, FileArray As Variant
  Dim TrackNum As Integer, SlideArray As Variant
  Dim Directory As String, pst As Presentation, DataSlide As Slide
  Set pst = ActivePresentation
  Set DataSlide = pst.Slides(pst.Slides.Count)
  Directory = "C:\Users\Admin\Desktop\"
  SoundString = DataSlide.Shapes(1).TextFrame.TextRange.Characters
  
  SlideArray = Array(1, 2, 3, 4, 5, 6, 7, 8, 9) 'add in the slides that need a sound file
  
  'Check that the dataslide is not in the array
  For x = 0 To UBound(SlideArray)
    If x = DataSlide.SlideID Then
      MsgBox ("Cannot use Slide number: " & x & " in array. Program ending.")
      End
    End If
  Next x
  
  For x = 0 To UBound(SlideArray)
    FileArray = Split(SoundString, "|")
    TrackNum = Int(Rnd() * UBound(FileArray))
    pst.Slides(SlideArray(x)).SlideShowTransition.SoundEffect.ImportFromFile (Directory & FileArray(TrackNum))
    'remove the song file from future slides
    SoundString = Replace(SoundString, FileArray(TrackNum), "")
    SoundString = Replace(SoundString, "||", "|")
  Next x
  DataSlide.Shapes(1).TextFrame.TextRange.Characters = SoundString
End Sub


The 2nd way just puts it all into 1 code and does the same thing using the last slide to store the data.

Code:
Sub SetRandomSongToSlides()
  'Adds a random song into a presentation using the last slide as a data slide
  Dim x As Integer, pst As Presentation, DataSlide As Slide, TrackNum As Integer
  Dim SlideArray As Variant, FileArray As Variant, FileName As String
  Dim Directory As String, SoundString As String
  Set pst = ActivePresentation
  Set DataSlide = pst.Slides.Count
  
  'Set up data here
  SlideArray = Array(1, 2, 3, 4, 5, 6, 7, 8, 9) 'add in the slides that need a sound file
  Directory = "C:\Users\Admin\Desktop\" 'Location of the sound files
  
  'add all file names to string
  For x = 1 To 100
    StrNum = x
    Select Case StrNum
      Case 0 To 9: FileName = "HYPE00" & x & ".wav"
      Case 10 To 99: FileName = "HYPE0" & x & ".wav"
      Case 100: FileName = "HYPE" & x & ".wav"
    End Select
    SoundString = SoundString & FileName & "|"
    FileName = ""
  Next x
  SoundString = Mid(SoundString, 1, Len(SoundString) - 1)
  For Each shp In DataSlide.Shapes
    shp.Delete
  Next shp
  Set DataBox = DataSlide.Shapes.AddTextbox(msoTextOrientationHorizontal, 94.125, 61.875, 383.125, 140.875)
  With DataBox.TextFrame.TextRange
    .Font.Size = 7
    .Characters = SoundString
    .Characters.Font.Size = 7
  End With
  
  
  SoundString = DataSlide.Shapes(1).TextFrame.TextRange.Characters
  
  'Check that the dataslide is not in the array
  For x = 0 To UBound(SlideArray)
    If x = DataSlide.SlideID Then
      MsgBox ("Cannot use Slide number: " & x & " in array. Program ending.")
      End
    End If
  Next x
  
  For x = 0 To UBound(SlideArray)
    FileArray = Split(SoundString, "|")
    TrackNum = Int(Rnd() * UBound(FileArray))
    pst.Slides(SlideArray(x)).SlideShowTransition.SoundEffect.ImportFromFile (Directory & FileArray(TrackNum))
    'remove the song file from future slides
    SoundString = Replace(SoundString, FileArray(TrackNum), "")
    SoundString = Replace(SoundString, "||", "|")
  Next x
  DataSlide.Shapes(1).TextFrame.TextRange.Characters = SoundString
  
End Sub
Now since that was so easy I made 1 more piece of code that will do everything for you and not even need a dataslide to store the information. This one will work right off the bat as long as you set up the slidearray and directory.

Code:
Sub SetRandomSongToSlidesNoDataSlide()
  'Adds a random song into a presentation using the last slide as a data slide
  Dim x As Integer, pst As Presentation, TrackNum As Integer
  Dim SlideArray As Variant, FileArray As Variant, FileName As String
  Dim Directory As String, SoundString As String
  Set pst = ActivePresentation
  
  'Set up the data here
  
  SlideArray = Array(1, 2, 3, 4, 5, 6, 7, 8, 9) 'add in the slides that need a sound file
  Directory = "C:\Users\Admin\Desktop\" 'Location of the sound files
  
  'add all file names to string
  For x = 1 To 100
    StrNum = x
    Select Case StrNum
      Case 0 To 9: FileName = "HYPE00" & x & ".wav"
      Case 10 To 99: FileName = "HYPE0" & x & ".wav"
      Case 100: FileName = "HYPE" & x & ".wav"
    End Select
    SoundString = SoundString & FileName & "|"
    FileName = ""
  Next x
  SoundString = Mid(SoundString, 1, Len(SoundString) - 1)
  
  For x = 0 To UBound(SlideArray)
    FileArray = Split(SoundString, "|")
    TrackNum = Int(Rnd() * UBound(FileArray))
    pst.Slides(SlideArray(x)).SlideShowTransition.SoundEffect.ImportFromFile (Directory & FileArray(TrackNum))
    'remove the song file from future slides
    SoundString = Replace(SoundString, FileArray(TrackNum), "")
    SoundString = Replace(SoundString, "||", "|")
  Next x
  
  
End Sub

And there you have it. If you are unsure on how to put this code in open up your presentation SAVE A BACKUP!!!!!! then press ALT + F11.
Go to insert and select module. Copy and paste all of the code into the window.
Close out the VBA editor.

now you can assign the macro of your choice to an autoshape so when you click it runs the code and sets up the slides. if you want the user to be able to click the shape and have the show go to the next slide just add
Code:
pst.SlideShowwindow.View.GotoSlide(2)
To the end of the code block to go to the 2nd slide after the code runs. If you need a different slide change the number in parentheses.


I typed this up pretty quick and ran a couple of tests but since I do not have 100 sound files I have not tested it 100%. If there are any issues let me know.

Thanks so much for the opportunity to learn more.

Sounds great. Here is one more that actually uses a collection. I think the previous codes would have never picked song 1 this could be fixed by adding a "|" to beginning of the soundstring but here is a very simple version of the code that will work right away.
Code:
Sub SetRandomSoundToSlides()
  'Adds a random song into a presentation using the last slide as a data slide
  Dim x As Integer, pst As Presentation, TrackNum As Integer
  Dim SlideArray As Variant, StrNum As Integer, FileName As String
  Dim Directory As String, SoundString As String, SoundCol As Collection
  Set pst = ActivePresentation
  Set SoundCol = New Collection
  
  'Set up the data here
  
  SlideArray = Array(1, 2, 3, 4, 5, 6, 7, 8, 9) 'add in the slides that need a sound file
  Directory = "C:\Users\Admin\Desktop\" 'Location of the sound files
  

  'add all file names to string
  For x = 1 To 100
    StrNum = x
    Select Case StrNum
      Case 0 To 9: FileName = "HYPE00" & x & ".wav"
      Case 10 To 99: FileName = "HYPE0" & x & ".wav"
      Case 100: FileName = "HYPE" & x & ".wav"
    End Select
    SoundCol.Add (FileName)
    FileName = ""
  Next x

  For x = 0 To UBound(SlideArray)
    TrackNum = Int(Rnd() * SoundCol.Count)
    pst.Slides(SlideArray(x)).SlideShowTransition.SoundEffect.ImportFromFile (Directory & SoundCol.Item(TrackNum))
    'remove the song file from future slides
    SoundCol.Remove (TrackNum)
  Next x
  pst.SlideShowWindow.View.GotoSlide (2)
End Sub
