Multichannel surround sound is characterized by its ability to deliver audio to multiple channels, enhancing the listening experience by providing a more immersive sound environment. The formats specifically associated with multichannel surround sound are Dolby Digital and DTS. These formats support various speaker configurations, allowing for complex soundscapes that can simulate a realistic audio experience, ideal for movies, music, and gaming.

PCM (Pulse Code Modulation) and Linear PCM are methods used to encode audio but are not exclusive to multichannel sound; they are often used for stereo or uncompressed audio. WAV and AIFF are containers for uncompressed audio formats and do not inherently support multichannel configurations. MP3 and AAC, while popular for compressed audio files, primarily target stereo sound and may support multichannel under certain conditions, but they are not typically associated with high-quality multichannel surround sound setups.

Choosing Dolby Digital or DTS highlights the specific formats developed to create and deliver multichannel audio, making them the correct answer when identifying formats that are inherently connected with this audio experience.
