| Dolby Digital | A high-quality audio format used in DVD-Video or Blu-ray and developed by Dolby Laboratories. This options allows up to a 5.1 channel mode. |
| Linear PCM | An uncompressed audio format. This format is mostly used for keeping the original quality of DVD-Video or Blu-ray, etc. It provides audio quality higher than an Audio CD but generates huge files compared to other formats. |
- Sampling Rate
Specifies the number of audio samples evaluated per second, which allows values between [48KHz] and [192KHz]. Regarding the bandwidth range of each format, please refer to the table of the Channel Mode settings.
* For Dolby audio, fixed at 48kHz.
* Usable values for playback depend on the player device.
* For Dolby audio, fixed at 48kHz.
* Usable values for playback depend on the player device.
