Gymnasiast has created a wonderful tool to ease the process of creating ride music objects.
You can use the tool here: RCTSpace[goes.rctspace.com]

Below I shall run you through the form:

You identifier: Fill in your username without spaces, special characters (with the exception of underscores (_)) or capital letters.

Object identifier: Fill in the name of your ride music style without spaces, special characters (with the exception of underscores (_)) or capital letters.

Creator's name: This should be your real name preferably, but if you are uncomfortable with this you my also fill in your username.

Style description (UK English): Fill in the music style name that should be displayed in the game.

Preview image: You can probably best ignore this, unless you know what you are doing.
The PNG file needs to be 112x112 saved using OpenRCT2's png palette format.

Music files: Convert your music to OGG vorbis* if you haven't already. Upload that in the boxes. This tool allows to upload up to three songs in the same ride music style.
Track name: Please put the original song name here.
Composer: Please put the original artist here.

*For converting to OGG vorbis you can use an online tool, or using Audacity or any other DAW.

Make a zipfile and rename .zip extension to .parkobj .
Make sure to use the following standard format when naming your files!
For <Type> in this case, just use "music". (For Example: auraspecs.music.dontyou.parkobj)

This renamed zipfile needs to contain the following files:
object.json and <NAME>.wav


OpenRCT2 accepts the following formats:
OGG Vorbis (preferred), WAV or FLAC.
At the time of writing OpenRCT2 plays everything back in a project rate of 22050 Hz.
This will be improved in the future.

Using a DAW, Audacity or online converter, convert your song to OGG Vorbis. Optionally you can take this opportunity to trim the ends of the song to make a perfect loop.
When saving make sure to name the file something simple, preferably without spaces.

Drag and drop the OGG file into the parkobj file.

At the bottom of this guide there is a guide on how to keep the size of a WAV file low. This should only be used for adding custom music for CUSTOM1.WAV and CUSTOM2.WAV for the original game, as well as OpenRCT2 version 0.4.0 and 0.4.1.


the "object.json" file can just be a txt file renamed to a .json file, I do recommend using Notepad++ to open it for easy working.

The "object.json" requires the following information. Feel free to copy and fill in.

Please keep in mind if the language file doesn't exist for a specific language it defaults to "en-GB".

My example:

- Add the .json to the parkobj file and you are set.
- Put the parkobj file in "\Documents\OpenRCT2\object\" and you are now able to select your own tune in the game!
Make sure to have cheats enabled, then you can select it in the object selector.

The wav file can be any music file that is rendered with PCM encoding.
My recommendations is to re-render audio file in Audacity to the following settings to minimize the size of the file:

-Set the project bitrate (see the lower left of audacity) should be set to 22050 Hz. // This so the bitrate is low enough to make the file size small, but not so low that it's noticable in game.



-Export as WAV, and when saving you can set the Encoding to the following: "Unsigned 8-bit PCM".

For the original RCT2 you can name it CUSTOM1.WAV or CUSTOM2.WAV and add it to the ObjData folder in Rollercoaster Tycoon 2's folder.

For OpenRCT2 make sure to follow the guide above and change the file link there to whatever you named your WAV file.
