Hello Myles,

DSD =3D Direct Stream Digital.

Recorders capable of this for field recording,

Korg MR1 since replaced with the Korg MR2
and Korg MR2000S for studio use (rack mount)

I use the MR2 as a backup to the Sony D50 which has lower noise pre-amps.

The variation seen in the blog entry is most likely attributable to the dif=
ference in plug in power voltage to the electret capsule used during the te=

Korg MR2 is a stereo recorder.  To capture "3D" Audio the closest I can thi=
nk would be to plug it into a binaural head, or your own using e.g Roland C=
S10EM binaural mics.

Not related to nature:
Korg MR2 Recording passing cars, with CS10EM binaural mics:-

Some nature sounds using the same Mics and Olympus LS10 recorder in Kamakur=
a Japan.

If you would like some recordings or have a specific test in mind for MR2 l=
et me know.

I think the Sony D50 is a better overall recorder in terms of noise. There =
is definitely "something" about the MR2 and DSD in general that sounds diff=
erent. Obviously this should be measurable, perhaps its due to less harmoni=
c distortion or transient response, but I'd be hard pressed to tell the dif=
ference between two identical sources routed to both recorders.

For field/nature recording the MR2's limiter is the best Ive found except i=
f the external mic preamp is noisier than the Sony D50's and noise is addit=
ive making the same recording with the D50 will inherently contain less noi=
se than the MR2.

Kind Regards,
