I recommend SoLuna. It doesn't display the location up front, but it gives you
the astronomical, nautical, and civil twilight times, too, and the moon times. I
start my dawn recordings at nautical twilight.

Hi Dan

There is an app called Sunrise & Set, which not only gives you the Sunrise & Set

Anyone on the list got a LS-10 for sale in great condition for a great
price? Mine just got pinched at Heathrow in London earlier this week
and I feel lost without it. Please contact me off list if you can't

Yep, this statement was somehow mixed-up (written late at night). I was
obviously thinking about super-cardioid (shotgun) microphones that are usually
quieter than omnis.

Oops - yes of course.  Despite having re-read the original a couple of
times before posting, I managed to get this scrambled.  Sorry for confusion,
folks.

I'm blaming poor concentration on the autumn/winter season here, with too
few birdies to record :-(

Hey Folks,

I know a number of us have iphones on this list and I am wondering if there is
an easy way to generate GPS coordinates on the phone?  I use it to take notes,

Thanks,

Yes Mike, the low-frequency response is quite good. Actually, I should have
better used a wind screen for the recording of the Robin this morning because
there are a lot of clipping artifacts in that recording.

Raimund,

Thank you :)

Looks like the internal mics are quite sensitive below 10Hz. The lows seem
similar to the R09HR which makes me question my comment about the LS10 not
having a low cut on even when its off.

Considering the M10s battery life and low noise internal mics its rather good.
Would be interesting to see how it sounds with the RME QuadMic via the line
input.

Added to the shopping list.

Sure Rob, I fully agree with that approach. There is of course no doubt that the
extra pounds are absolutely necessary if one wants to get the best possible
results.

What I originally meant is that one can already use one of the larger and
heavier recorders because the additional weight and volume can be neglected when
you consider the additionally required components. So, why do you complain about
the higher noise levels in those tiny pocket recorders? The price of the Fostex
FR2-LE for instance is also very acceptable in my opinion.

Raimund

Yes, that's true, which is why the D50 has the noisier mics, which poorer

looks to me like the m10 can be mounted in a dish. no modifications except
perhaps a baffle cut to shape. i tried this briefly with a zoom h2 and it works.
just treat the recorder as if it was a microphone.

Raimund and Robin--

Sorry, I did not see that Sony provided this info. Just grabbed the
manual. The M10's mics are only ~3dB(A) noisier than Klas' EM-23's.
~5dB(A) lower than WL-183's. Looks like there are some peculiarities
for an omni polar pattern but its still big improvement over the
D50's and D1's.  The off-axis peak at 90 degrees probably improves
the front/center (and rear center?) imaging if the capsules are
opposing. (In regard to Ernst's reservations the other day, the M-10
looks like the engineers could have given considerable attention to
on-board mic design and performance.)

Jerry White is planning to do some comparison tests including his
M-10. Maybe we'll figure out a way to include some popular external
arrays like AT-3032's in a parallel boundary so we can make the
differences more concrete for our ears.

I'm all for simplicity if quality is not sacrificed-- even for a bit
less quality if there's a LOT more simplicity.  More connectors =
more risk.

17dB(A) self-noise capsules suggests that Sony could be turning an
ear to our needs. How about an M11 model with detachable capsules
that can be placed in other, small external arrays with 6' foot
extension cables?

One can detect the faint input noise of the Hi-MD recorders at -124
dBu (A-weighted) when used with NT1-A's. If the D-50's input noise is
-126 dBu (A-weighted), it might be inaudible with NT1-A's (when used
with a Rolls/Art Phantom II).

The audible difference between 6-10dB(A) self-noise and 17 dB(A)
self-noise is breath taking in a recording of a quiet setting. I feel
its important to make sure one's end-product-goals are well defined
and equipment selected accordingly.

It is possible for convenience to inhibit skill development. Not to
suggest that any of the refined skills of the recordists on this list
would be compromised with a smaller recording system, but convenience
can disrupt the decision-making processes if one is not alert.  When
video camcorders were introduced, beginners thought much less about
making shots. Having to set-up a mic stand makes one really think
about mic position-- critical.  Its not easy to make good recordings
as we are always pushing the limits of the gear. For me, "quality"
must be consciously created on several levels.

I'm not at all concerned about a few extra pounds if they serve my
purpose. :-) Rob D.

Yes, the SONY website says that the M10 has omni-directional mic capsules, which
is also obvious from the design of its housing (there are no rear vents).

The common rule that cardioid mics are noisier than omnis might be true in many
cases. But there seem to be exceptions, such as the Sennheiser MKH20 (10dBA) and
MKH40 (12dBA) for instance.

Hi Michael,

according to my own measurements, the noise floor of the M10 line input is
approximately -92 dBu(A), measured at the maximum recording level setting
(position 10) that provides a clipping level of -2 dBu. This confirms the
specifications provided by SONY, which says that the S/N Ratio should be 87dB or
greater.

Subjectively, I can also confirm that the built-in mics of the M10  are indeed
quieter than the those of the D50:

http://tinyurl.com/ybrpjan
http://tinyurl.com/yzkopq2

So, I would say that the M10 is a great recorder for its small size and moderate
price. I agree with Robin that there is probably no reason to worry about the
fact that the EIN of its microphone input is not superior.

One should always keep in mind that very quiet microphones (such as the Rode
NT1A or the Sennheiser MKH's) are usually quite bulky (not to mention the
additionally required tripods and windscreens). So, if one needs the lowest
possible EIN, then there are already a number of suited recorders available
(Fostex FR-2LE, TASCAM HD-P2 and of course the SoundDevices 7xx series
recorders).

Raimund

Michael--
It might be informative to search, "H2 line
external pre" in the list archive. I could detect
no additional noise in my comparison between
NT2000's ->MP-2-> (unbalanced line) H2 and
NT2000's ->MP-2-> (balanced line) 744T.  The H2
has reliable, long-duration file handling and
simple button/menu usage. The H2 feels fragile,
especially its SD card cover, but my unit has
withstood a few drops.

One might suspect that the A-D in a more
expensive recorder like the Sony could sound
better,..  I'd be curious to hear a stringent
comparison of transient sounds myself,.. Curt was
the first to give positive accounts of the MP-2
->H2 combo and I concur.  Rob D.

Does anyone know what the noise floor of the line input is?  I would
love to use a small recorder like that with my sound devices mp2.  A
lot of these small recorders don't have true line inputs - instead
they are often hi-z inputs like on the zoom products.

Anyone here passing nature recordings into cymatic phenomena? I would be
interested in hearing/seeing any specimens, if so.


"Cymatics also known as modal phenomena, is the study of visible sound
and vibration, typically on the surface of a plate, diaphragm, or
membrane. Directly visualizing vibrations involves using sound to excite
media often in the form of particles, pastes, and liquids. "

Interesting brief video talk on cymatics:

Prices adjusted (down) on Edirol R-09HR, Tascam DR-1, Samson Zoom H4n and Tascam
HD-P2. Prices will continue to fall, especially as new models come out. I will
not guarantee to track these, so please hunt for the best deal!

I have found that amazon.com is a poor price guide, since they are very volatile
and change depending on what third-party dealers are offering. Also, their
prices do not translate to anywhere outside of the USA. Prices from major
musician's retailers correspond a lot better to the UK, Germany or wherever.
(Though you may need to scale up all the values.) I have used ProSound & Stage
Lighting, Full Compass Systems, J&R Music, B&H and Musician's Friend to
establish the baseline.

It's a great shame the D50 does not have XLR/phantom, as then its lower noise
could be matched to some quiet mics without needing yet another device in the
way. As it is, I prefer to use a proper shoulder unit with XLR and phantom power
built in, especially as you can get an FR-2LE for cheaper than D50 plus phantom
power box.

When using the built-in microphones the M10 has radically better sound than the
D50, according to Sony's own graphs. This was a total shock to me! For the price
it's hard to resist the M10 as a second recorder, one small enough to always
carry with you.

Thanks to All for the evaluations.
