The VRML specification is powerfull enough for enabling the creation of animated 3D worlds, where sounds are an integrated part. More important is that VRML browsers and personal computers have the capability to accept large sound files, and to mix them in a 3D environment, thus preserving the sound quality. Of course, due to the limited bandwidth, we can only present worlds with small sound files, in fact MP3 files. You can hear the sound only if your VRML Browser support this format (please visit the tools page for more information).
