How to put a wav file onto mikumikudance?Visit LearnMMD's Video Channel on YouTube: Videos by Reggie Dentmore.

MikuMikuDance has a very simple music feature: it requires a WAV file … and it always starts playing the WAV file at Frame Zero.

Understanding the sentence, above, is almost all you need to know about the use of music in MikuMikuDance!The EFFECTS Menu in Audacity® 2.o has most of the tools you will use to enhance your WAV file.

Make & Manage your WAV File:

Those simple rules mean that you must control your WAV file before you load it into MMD. If you want the music to wait a few seconds before it starts, you have to add a few seconds of silence to the front of your music track. Can you set the music to play in certain frames? No … you have to edit your music file; inserting seconds of silence in the places where you want no music. The WAV file starts playing from Frame Zero: that’s the law.

“So … How do I put my music into MMD 7.39 …

… and how do I edit a WAV file,” you ask? With your WAV file saved on your computer, Open MMD, open your dance file and, under the FILE menu choose LOAD WAV FILE.  How do you edit the WAV file? That, too, is simple … well … the mechanics of the process are simple. Getting the timing to be exactly what you want may take a bit of doing … but …that’s the FUN part!

MikuMikuDance will not play Mp3 files. It won’t play music from your CD’s. You will need an audio editing software that will open your music files and convert them to WAV files.

I use AUDACITY® 2.0

… a free download … it’s fun and easy to use.Visit the DOWNLOADS page to get the link for Audacity 2.0 Audio Editing Software.

Most simply: open Audacity, IMPORT your Mp3 or other music file … and EXPORT as a WAV file. That’s it … almost no other keystrokes required.

There’s a lot to learn about Audacity … it is both easy to use and very powerful.

Use IMPORT to bring your music file into Audacity. Choose EXPORT to make your WAV file. You’re done!  … … or use Audactity’s power to create the soundtrack you really wished for!The Audacity Generate Menu lets you add silent breaks to your WAV file.

The GENERATE menu has the “Silence” tool that let’s you insert silence, very precisely.

The EFFECTS menu has most of what you will use. I highlighted the tools I have used … and put in an orange arrow to point at the Voice Remover … that could be fun to play with!

Use Control A to “select all” of your music file … or click and drag to select portions of the music.

NORMALIZE is used to set your entire music piece to a CD-Normal volume.

AMPLIFY allows you to “turn up” or “turn down” the volume for any selected area (or the whole piece) of your file.

FADE-IN: Select a portion of the beginning of your music and select Fade-In. Audacity reshapes the wave to achieve the fade-in effect. FADE-OUT work s the same for the end of your piece … or you can use these effects in the middle of your music to have the music fade-out for a few moments and then make it fade back in.

Metal Miku of MikuMikuDamce 7.39CLICK-REMOVAL is for those of you recording from vinyl LP records. Audacity identifies and removes clicks and pops from your music. There’s also “NOISE REMOVAL” that removes turntable rumble and the like.

You can layer multiple recordings to add applause tracks or mix-in more than one piece of music … or to add voice-overs. Open/import your various recordings/sound files as separate projects in Audacity. Add new tracks to your main project and then copy/paste your other music/sounds into the new tracks. You can copy/paste to move bits back and forth along the time line. You can push PLAY at anytime to hear how you are doing.

When you are happy with your Audacity project, EXPORT to WAV file.

Manage the WAV file in MikuMikuDance 7.39

MMD has a few quirks for you to remember:

— Use LOAD WAVE FILE to connect your dance project to the WAV file. If you later make changes to that WAV file, MMD will play your latest version with the changes. MMD plays your WAV file, it doesn’t “store” it.

— To change to a new WAV file, just use LOAD WAV FILE and select the new file.

— To not hear the WAV file, click NOT PLAY WAVE FILE. To actually remove the WAV from your dance project, just change the name of the WAV file so MMD can’t find it. When you, then, load that dance, you get a message saying “MMD can’t find the WAV file.” “OK”

TO RECORD A VIDEO, you must start recording from Frame Zero or else the music will not be part of your video. I have panicked a couple of times when making a test video from the middle of my project: “Where’s the music? It was there a minute ago!” … Just start the Render to AVI from Frame Zero.

I think that’s it!

    hey guys! Im having an issue with WAV files working perfectly when im working on something, but once I save it as its own project and I load it up again, *no* WAV files will work, and it wont even play with frame. I tried this on two projects and they were both saved as their own projects, but WAV files will not work anymore :””) any help would be appreciated

      never mind! in a turn of events it was a problem with my laptop. Apparently there was no audio coming from anywhere, so I troubleshot and restarted, and the audio came back!

    Alright. I successfully got a WAV file from audacity, it’s all booted up, and I go to try and put it in the animation. Nothing. I must’ve tried putting it in like five times. So I extend the frame counting screen for a reason I can’t recall, and I see that the sound starts to show up on frame 35. Despite the article saying it would start on frame zero. Can I get rid of the failed attempts I put in, and find a way to put the sound in its proper place? Help?

    • Reggie_Dentmore Reggie_Dentmore

      Yes… As you Render to AVI, you need to start at frame Zero or else the sound will not be recorded in that resulting AVI file. … but what you are talking about is adding the WAV file to your MMD animation… and then not hearing anything, not seeing the sound waves until frame 35, or so. … Take a look at your WAV file in Audacity. Does the first sound start at the very left-end or is there quiet space before the music starts? … Gotta highlight that blank space at the beginning and DELETE so that your music starts at the very left edge of the timeline. … yes?

    i find this to be a strange phenomena

    file -> load WAV file
    music bar shows no sign of music
    plays the animation
    no sound
    clicks on any menu (file, edit,etc)
    music starts playing

    i don’t know how this came to be but i would like some help please.

    I converted a mp3 file in Audacity, then I exported as “WAV (Microsoft) signed 16-bit PCM”. Then I opened that WAV file in my music player and I figured out, it’s working properly. But, when I load it into my MMD, it says, “this is not WAVE (PCM) file”. I don’t get it, please help me..

    • December 30, 2017    

      If you uploaded the .wav file someplace for us to download, we might be able to figure out what’s happening. I don’t have any problems doing this with Audacity 2.0.5, so can’t reproduce your problem.

    After importing the audio, then exporting into 16-bit PCM, and then adding it into mmd, the .wav file wouldn’t work . No error would show up regarding this, the wav file won’t play in mmd. That’s it. (forgive my broken english)

    • August 27, 2017    

      Can you opem the exported .wav file in a music player? Does it work there?

  6. jollyrancher jollyrancher
    February 26, 2017    

    I converted my file to a wav file perfectly ok, but when I pressed load wav file and clicked the wav file, mmd said “cannot find wav file”? I’m 100% sure the file is a wav file because under file type it says, WAV File. Please help.

      Did you use Audacity… and do an EXPORT… and you selected the WAV option 16-bit PCM… ?

      • jollyrancher jollyrancher

        Yes :(

    help! I was trying to do a music wav file but please help please AutoSave file was!

    • February 16, 2017    

      Explain your problem in *understandable* terms, please.

  8. January 3, 2017    

    help, i tried loading the wav file and it works, but the only problem is that it doesn’t start playing until frame 200 or so. How can i fix this?? Thanks!

    • January 3, 2017    

      Frame 200… that’s about 7 seconds. Does your file start immediately when you open it in your regular player? Or that’s the way it is made?

      • January 4, 2017    

        yes, if i were to play it in something else, it starts normally, no problem. Also, with my other WAV file, when i play it, it starts at frame 0. Only with this file its having problems.

      • January 4, 2017    

        yes, if i were to play it in something else, it starts normally. Only in mmd it starts at a different frame.

        • January 4, 2017    

          Where did you get it from? I’d like to take a look.

      • January 4, 2017    

        yes, it begins normally in another player. All my other songs play in frame 0 also.
        *Sorry if theres more replies from me this is messing up horribly*

    So, I just want to confirm that if you load a .wav file into MMD, then change the name of the file, the .wav file opened in MMD will just disappear?

    • February 20, 2016    

      If you mean that you rename while MMD is still open, you just can’t. If you rename it after saving a project, then yes, it’ll most expectedly “disappear”.

    How do I make my WAV file start at the same with the Motion Data?

    • UtVdL UtVdL
      February 16, 2016    


    • February 16, 2016    

      You can’t. The .wav file always starts to play from frame #0. If your motion doesn’t match, you’ll have to modify *it* by using “insert/delete frame line” commands in “edit” menu.

  11. Elina Elina
    January 16, 2016    

    I’m making a Tell Your World MMD, and I have the model, everything, but when I loaded the WAV file, and play it, the model does the motion, but there’s nothing coming out.
    My speakers are working fine, my computer isn’t mute, and I’m pretty sure I downloaded the WAV file right.

    please help.

    • Elina Elina
      January 16, 2016    

      And I even tested out another WAV file, and that’s working.

      • KillerBeer KillerBeer
        January 16, 2016    

        In such case some of your file’s properties must be incompatible with MMD. Right-click the file that works, select “Properties”->”Details” and look for the “Bitrate” line – is it the same that the non-working file’s? You may try to edit it in Audacity and “Export” as “WAV 16-bit PCM” file.

    Hello I have been having trouble making my videos on MMD when I record it even if I start it from frame zero it still doesn’t play the music. Is there a way for me to fix that? If there is please tell me.
    Sincerely Sapphire

      On the pop-up that lets you choose your video compressor (Raw, Video 1, etc.) is the WAVE box checked?

      • Sapphire Sapphire
        November 14, 2015    

        Yes it is but after I record my video it never plays the music and I don’t know why
