WARNING: THIS CURRENTLY ONLY EDITS THE .OSU FILE. TO HANDLE THE MP3 CHANGES, CHECK OUT THE BOX BELOW.


How to change the MP3 file with audacity
0. If you need to download audacity, click here.
For MP3 exporting, A program called LAME is required. To download LAME, click here

1. After opening audacity, go to File -> Open or press Ctrl-O and choose the appropriate MP3 file. Alternatively, the MP3 file can be dragged into the window.
2. After the MP3 file has loaded, go to Effect -> Change Tempo as shown here:

3: Enter the percent change value you want and press OK. For an example of what value you need to enter, check this chart (The values on the right are the values you enter into audacity):
Image
4. Go to file -> Export Audio or press Ctrl+Shift+E and choose where to save the MP3 file and press Save. The file needs to be saved into the folder of the mapset you are planning to change the rate of. If saved in any other folder, the process will not work. Give your file an appropriate name as you'll need to enter this value later in the actual rate change program.

IF YOU WANT TO RATE CHANGE THE SAME MP3 FILE MULTIPLE TIMES, MAKE SURE TO PRESS CTRL-Z BEFORE CHANING THE TEMPO AGAIN. FAILURE TO DO SO WILL RESULT IN INCORRECT SPEEDS.

And now onto the actual program (hopefully this is a stable release).
This program takes in any osu-mania file (and only osu-mania files) and allows a change to the speed of the map to any non-zero value. Simple as that.
This program is still in beta stage and has no error-checking currently so don't try and break it because you will and that's your own fault.
Download link is here. Just extract and run the .exe file.
To see a map where difficulties where created using this program, click here.


A guide to using the program
1. After program has opened, click the Input button, and choose the .osu file of the map that you want to change the rate of and click Open.
2. Enter the name of the mp3 file that you created earlier into the box labelled "Audio Filename:"
3. Enter the speed % into the last remaining box as labelled on the program and press "Go". Once the file says "Conversion Complete", then the file is created.
4. Go into game and enter the song select menu unless you're already in the song select menu, and then press F5. The file should now show up working fine.


Changelog:
  • Alpha 1.0: Program running but only supporting the majority of v14 files.
  • Alpha 1.1: Added support for v12 files.
  • Alpha, the v12 patch update: Enabled support for v12 files.
  • Alpha, the colourful patch update: Added support for a file that contains combo colours (broke previously, found thanks to Zenx).
  • Alpha, the musical patch update: Added support for internal hitsounds, events and bookmarks.
  • Alpha, the musical mini patch update: Removed files that are unnecessary to the public, reducing the file size by 85%.
  • Beta, the accessibility patch update: Added support for decreasing rate values (values below 100%) as well as posting to the forums for more people to access, as well as a hotfix to missing notes.

Since this is in beta, and the files in alpha have had minimal testing, bugs are expected and will show up. If any bugs that are not expected (aka if you enter 0 in the rate change and tell me there's a bug you're going to get slapped), please post as a reply in the forums and I should have hotfixes out within 24 hours.
Files that have multiple bookmarks and have a Storyboard layer 0/1/2 are most likely to break at the moment. If this does happen, report immediately.

On top of that, if there are any features you would like to see except for the ones mentioned below, feel free to leave a reply and I'll see what I can do to implement them.


Current planned features:
  • automatic MP3 file rate changing
  • external storyboard support (maybe cancelled)
  • video rate changing (that goal is somewhere far off in the future)
  • continued support for any previous and future changes to the osu file system.

Have fun with those new files!

ok so it doesn't seem to work for me. I used Audacity to change the speed of the MP3 and then saved it to the copy version of the beatmap folder i wanted to change. Then I used the program and made sure I put the title exactly the same as what I named the MP3 File. Which both the beatmap and the Mp3 appear in the beatmap folder with the same file name (just different extension) yet I still hear no audio when I play the map
