Mono Rec On Himd, What Happens?

The result of recording in HiSP and HiLP [64] ATRAC3plus modes in mono is that you should basically get the full bitrate's encoding bandwidth dedicated to the one channel that is used.

i.e. if you record a mono signal in HiSP, it should be using the full 256kbps bandwidth for the one channel, rather than splitting it between two.

Since HiSP and HiLP, as with ATRAC3's LP2, are joint-stereo [M/S stereo] encoding formats, having a single channel active or both channels active with identical signals mean that the full encoding bitrate should be dedicated to recording the one signal.

In theory the quality of a mono channel should for the above mentioned reason be better, or?

2nd is that 256kbps vbr? when I calculate the amount of minutes on a full himddisk and compare that with the bitrate it doesn't match is more than 30 mins off(?)

thx

Yes, it should be the quality that the full bitrate on a single channel can provide, which should be better than "normal" [i.e. with stereo recordings].

MD and HiMD are constant-bitrate media. Among other things, constant bitrate and a fixed packet time-length [the time duration of each chunk of sound in ATRAC] are what make editing and gapless playback possible.
