Making settings in Mac (continued) Enabling playback with even higher audio quality Selecting the DSD decode mode With the TEAC HR Audio Player, you can choose the playback format. Select [Preferences...] from the [TEAC HR Audio Player] menu to open the Preferences window. Set the [Decode mode] item to [DSD over PCM] or [DSD Native], as you prefer. ATTENTION oo Select DSD native format to play DSD files with the highest sampling frequency (11.2 MHz or 22.5 MHz) supported by a connected UD-505 or another unit capable of DSD playback. Playback operations are possible when "DSD over PCM" is selected, but no sound will be output from the connected device. Selecting the data loading method You can set how files are accessed for playback. Select [Preferences...] from the [TEAC HR Audio Player] menu to open the Preferences window. Set the [Audio Data Handling] item to [Normal] or [Expand to RAM]. For playback with even higher audio quality, select [Expand to RAM]. DSD over PCM Using the DoP (DSD Audio over PCM Frames) playback method, the DSD signal is embedded into an ordinary PCM format signal for transfer. DSD Native The DSD data is transferred directly without PCM conversion or other change. 10 Normal Data is loaded in the same manner as ordinary file access. Expand to RAM The file to be played back is loaded into RAM once before playback. Playback can be made more stable because loading does not occur at the same time,and this enables playback with higher audio quality. When [Expand to RAM] is selected, you can set the maximum amount of memory to be used with this function. Set the amount of memory used to load audio files according to the formats of the files that you play back often. oo When [Expand to RAM] is selected, it may take some time to start playback if the processing speed of the computer is slow. oo Do not set this value higher than the amount of available open memory. The available open memory should be more than this setting, and this setting should be more than the maximum file size.
