Don't mind the mess!
We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.
Sound System Options
To play audio in your game, Panda3D can offer you the following three choices of audio libraries:
- OpenAL is a well-known and popular open-source audio library. Panda3D uses the OpenAL Soft implementation.
- FMOD is a powerful proprietary cross-platform sound engine that supports various types of sound files - MP3, WAV, AIFF, MIDI, MOD, WMA, and OGG Vorbis. However, its license restricts you from using it for commercial purposes unless you actually purchase a special license. Non-commercial use of FMOD is free of charge. (For more information on this, visit the FMOD Licenses page.)
- Miles is a sound system that is not included in the downloadable binaries of Panda3D. In order to use this you will need to purchase Miles and compile Panda3D from scratch using the ppremake system
If these choices are not enough for you, then you can try other sound libraries.
Setting the Sound System
To configure Panda3D to use a specific sound system, you will need to change your Config.prc configuration. You should look up the variable
audio-library-name and change the value to one of
miles_audio. (The names of the libraries may differ with the way Panda3D was built.)
If you don't want to use one or both of the libraries shipped by default with the SDK, then you can remove the associated library files after installation or compile Panda3D from source with the appropriate settings to keep them out of the build.
Note for users of Panda3D 1.5.4 and under: If you are using FMOD and a 64-bit operating system, you might run into a strange assertion error or even a crash if the memory address of the sound exceeds 4 billion. This is because of an issue in FMOD. To avoid being affected by this issue, you must make sure your memory usage doesn't exceed 4 GiB (which is not likely, and even impossible on 32-bit systems).Previous Top Next
