4gb of storage is nothing when you put high-Rez uncompressed files on it.

Even adding a 32GB microSDHC card (36 GB total) leaves you feeling cramped.  I've currently got two cards - split by genre.

I was wondering if someone could help me with some information that I could not find in the manual. I currently use a tascam dr-08 but I'm running in to a problem.... perhaps the PCM-M10 would solve the problem...

Just like the PCM-M10 the tascam has its built-in folders of 2GB. If the recording goes beyond that, a new folder is created automatically. The problem is that there's an audio gap between one folder to the other once the track is merged.

The PCM-M10 has 10 folders in its built-in memory of 4GB. My question is: 

1.How big is each folder? 

2. If my recording goes beyond a folder, would I get a gapless audio when I merge the tracks or there's no solution?

I'm recording about 3 hours in 24/48K

any help please?Posted Image

Hey poptart,

 

I don't know the answers to your questions, in part because I use the PCM-M10 exclusively as a player, not as a recorder.  

 

I recommend you find the PCM-M10 thread at http://www.taperssection.com - this is where all the field recording people hang out.

 

Just Register (it's free), then start a new thread to ask your question in the Recording Gear forum (after searching to see if you can find answers, of course.)

An update regarding the Sony PCM-M10's DAC

 

A very generous Head-Fi member who lives near me has loaned me some of his gear while he is on vacation.  This includes an April Music Stello DA100 DAC that I have had in my possession for about two weeks now.

 

I've spent about eight hours, thus far, comparing the following component chains:

 

44.1/16 and 96/24 WAV files > Sony PCM-M10 Line Out > Meier-Audio Corda Stepdance > Audez'e LCD-2

 

   vs.

 

44.1/16 and 96/24 WAV files > Win7 laptop > USB > Stello DA100 > Meier-Audio Corda Stepdance > Audez'e LCD-2

 

Having copied to the laptop's hard drive, several WAV files from my PCM-M10's 32 GB microSD cards, I am able to hit "Play" on the laptop and on the Sony PCM-M10 to begin playback simultaneously, then I just swap the cables going to the Stepdance analog input jack so that I can jump back and forth from listening to the Stello DA100 DAC vs. the Sony PCM-M10 Line Out.  I have also adjusted the volume level on the laptop to match that of the Sony PCM-M10 Line Out.  This allows me to use the Stepdance volume control at will, impacting the two DACs equally as heard in the Audez'e LCD-2s.

 

Interestingly, both DACs are sigma-delta designs and the digital inputs of both can handle sampling rates no higher than 96kHz at a depth of 24 bits, but the Stello DA100 offers a 192kHz upsampling chip to provide a function not available with the Sony's DAC, with a switch to Bypass 192kHz upsampling, so that, if you prefer, you can hear the digital file converted to analog at its native sampling rate, be that 44.1, 48, 88.2, or 96kHz.  The WAV files I'm using in this comparison are either 44.1 or 96 kHz.

 

Keep in mind, most people would agree that upsampling cannot possibly increase heard detail beyond that which was originally recorded.  It's analogous to trying to use Photoshop to resize a 6 Megapixel image capture in hopes of getting it to compete with a 12 Megapixel capture.  Sharpening tools can be used to improve the acutance (edge or boundary sharpness) of an upsampled image, but you will still have no actual increase in resolution of the original content.  Continuing with the analogy, if a distant person's face is unrecognizable due to insufficient resolution in the original capture, they will still be unrecognizable after upsampling and sharpening.  

 

Focusing my attention on recordings where there is a lot of intrinsic detail (soundtracks of "Inception" and "Tron Legacy", for example, and some classical and jazz pieces where there are a lot of voices that are difficult for a DAC to separate and image), my very first impression from perhaps 30 minutes of listening was that the Stello DA100 was retrieving a lot more information than the Sony's DAC.  I even described the experience as a "revelation" in a thread  where I posted about it at the time and the experience sent me immediately into considering the purchase of a 160GB iPod Classic + Cypher Labs AlgoRhythm Solo (perhaps the best truly portable DAC available) as a replacement (a very expensive replacement) for my Sony PCM-M10.

 

I now regret having posted those impressions of the Stello DA100, because I'm utterly convinced they were premature and based almost entirely on listening to the Stello DA100's 192kHz upsampling feature.

 

I've spent easily six full hours now, listening very critically, comparing the Stello DA100's 192kHz upsampling mode vs. its Bypass mode vs. the Sony PCM-M10 Line Out and early on concluded, and have continued in my conviction, that the 192kHz upsampling had initially infatuated me with something that was simply new to my ears, but which really doesn't offer more detail, transparency, accuracy, air, soundstage, or imaging than the Stello DA100's Bypass mode or, get this, than my Sony PCM-M10's Line Out!

 

I first came to this realization by just comparing the Stello's 192kHz upsampling mode to its own Bypass mode, across many tracks.  You can't make a silk purse from a pig's ear.  If the detail isn't there to begin with, making it sharper doesn't reveal more detail.  And that's the best word I can come up with to describe the difference between upsampling and bypass on the Stello DA100 - it's sharper - more etched - much like a Photoshop image where edge contrast has been increased through use sharpening tools, but there is no real increase in resolved subject detail.   I've come to find the upsampling fatiguing - it's unnaturally etched, where the Bypass mode sounds musical.

 

And having now spent several hours comparing the Stello's Bypass mode to the Sony PCM-M10's Line Out, where the analog side of the Stello's DAC is heard at the native resolution of the inputs I feed it, I'm convinced that I can hear only one trait which significantly (but not dramatically) betters the performance of the Sony PCM-M10's DAC:  improved bass extension.  

 

All that said, I must still say that that Stello DA100 seems to offer just a wee bit of a resolution advantage when listening to 96/24 WAV files in Bypass mode - it's not significant and I would say it's hard for me to discern in all but the most challenging signals - nothing like the difference I had thought I was hearing with my first exposure to the Stello using 192kHz upsampling - where I was smitten by its sparkle.  rolleyes.gif  Though "sharper," the upsampling does nothing to improve separation of voices or instruments which sound like a homologous blob with lesser DACs.   The upsampling also does nothing to expand the soundstage or focus the imaging. But it sugar coated my initial comparisons, nevertheless.

 

Conclusion:

 

The Sony PCM-M10's 96/24 DAC, as heard via Line Out to a Meier Corda Stepdance (famous for it's resolution and transparency) and Audez'e LCD-2 (even more revered for these same traits), at least to my ears, offers something like 98% of the resolution and detail offered by the Stello DA100 DAC, with the Sony PCM-M10 falling short of the Stello DAC more significantly, but still only slightly, in the area of bass extension.

 

I'm far less interested than I was previously in replacing my $239.00 Sony PCM-M10 with nearly $1000.00 worth of iPod Classic + Cyber Labs AlgoRhythm Solo +  interconnects.   I'm still very interested in making that comparison, but haven't had the opportunity to do so.  From what I've read, the Wolfson DAC in the Solo could put the Stello DA100 and PCM-M10 DAC's to shame.

 

Meanwhile, since no one has popped up out of nowhere offering to lend me their Classic + Solo, I have spent considerable time researching the inventories of various Head-Fi members (by studying their profiles) and have isolated a candidate to whom I have sent a PM suggesting he accept my offer to lend him my Sony PCM-M10 for comparison to his MANY different portable sources.  This member has ALL the good stuff - iMod, Classic + Solo, HiFiMan 801, etc.  and his posts have exhibited a particular interest in playing 96/24 files portably - which the iDevices can't do, due to their 48kHz limitation.

 

I just sent that invitation yesterday - no response as yet - but I can't wait to get the opinion of someone so well equipped and experienced as to the performance of the Sony PCM-M10 Line Out.  

 

Stay tuned...  

 

Mike

Mike, thanks for the nice work up.  I have the PCM D50 and I also have the Ipod+CLAS combo.  Before I received my Solo, I purchased the DB1 and I compared the D50 optical out to Line out to headphone out and I can tell you that there is a big difference between the optical out and the line out suggesting that my D50's dac is not up to par with the DB1's wolfson dac.  I think in another thread on the D50, I learned that the PCM-M10 may have a little better DAC.  But your result that the M10 is 98% of the Stello DA100 is a big surprise to me.  When I compare the optical out to my ipod/CLAS combo, the difference is also very huge.  That couple with the unfriendly user interface of the D50/M10, I have now stop using the D50 as a DAP.

Thanks for your input Jalo!

From the seat of my pants, I cannot imagine that the PCM-M10's Line Out could sound as good as a CLAS, and thus, I'm still eager to lend it to a CLAS owner. The original person I had in mind, DJ Nellie, has now accepted my invitation, but I had already sent the PCM-M10 to Misterrogers in response to his unsolicited PM regarding the PCM-M10.

Misterrogers does not own a CLAS, but he does have a Music Streamer II+ and a NuForce Icon HDP Line Out with which to make comparisons, but my lending it to him was as much to satisfy his desire to check out the PCM-M10 as to get his opinion of its DAC.

Even with your comparison of the D50 to the CLAS, I won't have the comparison I'm seeking until I send the PCM-M10 to DJ Nellie (2nd in line). I could send it to you, too, but I don't know how long I can suffer using my LCD-2s with a Sansa Clip! :-)

Ultimately, I want to know the truth regarding the PCM-M10's performance, or at least a consensus of opinion. At this writing my personal experience is limited to comparing it with it's own headphone out, my Sanza Clip, the Stello DA100, and 5.5g iMod I'm borrowing from tnmike1. Again using the Stepdance and LCD-2, the iMod is a tad more diffuse than the PCM-M10 Line Out, but much warmer, with almost a tube-like quality that's fuller and quite endearing. Still, the detail falls short, in the highs especially - and I'm not confusing the fact that it's also a bit darker.

I too remember reading a post somewhere in which the author was antagonistic to the use of either the D50 or the M10 as a DAP, but he strongly preferred the M10's Line Out to that of the D50.

So, the PCM-M10 continues to discourage my purchase of a CLAS rig, but I'm doing my best to find evidence that would upset its grip on my ears.

Thanks!

Mike

So which one is a better mp3 player, the M10 or the Zoom H4n?  I didn't see that one mentioned on this thread unless I just missed it. 

post #41 of 217

Hi nonsupremous!

 

I don't know, but I've read at www.taperssection.com that some people consider the Zoom H4n to have better built-in microphones (it's a better recorder, in their opinion).  

 

That's the problem with using these PCM recorders as players - there's hardly anyone out there reviewing their playback capabilities!  Field recordists, like the forum members at www.taperssection.com, only use the playback functions as a convenience feature while on location.  When they're ready to edit their recordings, they pull the microSD card out of the recorder, stick it in their PC or Mac, and never think twice about listening to those files using the recorder's built-in DAC and headphone amp.

 

By the way, at the moment, my Sony PCM-M10 is in the hands of Misterrogers (Head-Fi member), who is evaluating its Line Out in comparison to several desktop DACs he owns.  He has given me some favorable initial impressions, using the word "impressive" to describe the sound of the Sony PCM-M10's Line Out, but I will encourage him to post a more conclusive opinion to this forum when he has shipped it back to me.

 

Mike

Thanks.  I will be looking forward to hearing a little more about it also.  It seems that the microphones on the Zoom are really strong.  There are just a host of other features in the Zoom that make me think it will take away from playback abilities.  Like all the options for guitar and bass amps.  That surely requires some resources! 

post #43 of 217

If you're going the recorder-as-DAP route, why not a Sony PCM-D50 or a Tascam DR-100 (note that the latter has worse recording capabilities, worse mics, than the D50)? Or not, disregard me.

Memory stick kills anything that's Sony proprietary for me.  I might as well commit Seppuku and go back to Apple.  YMMV.  So the M10 is acceptable.  biggrin.gif

post #45 of 217

How can you go back to Apple when your innards are splattered all over? :D

I'm hoping M10 > HM602?
