1 GB SD Cards?

[Len M.]

Panasonic announced a 1 GB SD card back in January. Lexar and Sandisk followed but none have released one yet and it's almost November.

Anyone know when we can expect to see a 1 GB SD card hit the market?

HI, I have only seen 1gig compact flash, and 1gig memory sticks.
That is going to be expensive 1gig secure digital. MY pockets are not that deep 8O
are u putting a movie on there?

[Len M.]

We're recording 24-bit/96 KS/s audio to uncompressed better-than-CD-quality wav files.

CF flash cards are available in sizes up to 6 GB now. SD cards are lagging.

We're waiting for the 1 GB SD cards to be released. When?

[Janak Parekh]

That's a good question, isn't it? I have no news right now; but believe me, we'll be posting it to the front page when we find out. :)

And believe me, the mentioned price will be so shocking. :mrgreen:
Good news is ... the 512 MB SD will get a further drop in price. YAY !

[tsb_hcy]

512 MB SD cards are pretty cheap now, maybe the 1GB cards won't be priced too badly. 1 GB SD is the answer for CF II GPS. 8)

I wrote Sandisk, Lexar and Panasonic to ask when they expect to release their 1 GB SD cards.

Lexar sales and customer support had no idea about when.

Panasonics customer support said that they have no information about when.

Excellent research there Len! That is so cool, I can't wait to see them come out, they are so tiny and really worth it! :D

[Thinkingmandavid]

haha, that sounded funny, justin, they are so tiny and really worth it!
I agree with justin, that was excellent research. I dont think I will be able to afford the 1 gig,mmmm that would be a lot of mp3s,
a lot of grad school papers
a lot of whatever :D :!:
I dont know. I wouldnt mind having more storage but at the same time it takes so long to go through that much storage. I am wondering if I am better off with more of 512 so I can actually have them per certain things, like said above, grad school, then this for that. mmm

[Len M.]

For recording uncompressed CD-quality audio, 1 GB is only 1 hour and 35 minutes of recording, or only half-an-hour at DVD-quality, so 1 GB gets used very quickly.

For music it really isnt that much, good point. I guess when you put it in its proper perspective, 1 gig may not be to bad :wink:

[JustinGTP]

1 Gig is a lot for music, it just depends how long your battery lasts :wink:

152mb is 2h 10m. That is a lot of music. So, therefore, 912mb is 13 hourse of music 8) - And that, BTW, is only 44 songs with bit rates of 128kb/s to 192+kb/s. That is a lot of music, I dont understand where you only got the 1 hour 35 minutes, and all of this music is not compressed and above cd quality audio (64kb/s)

-Justin.

[Len M.]

Sorry, you're mistaken.

MP3s and MiniDiscs use lossy data compression (MPEG3 and ATRAC respectively). CDs, in contrast, are not compressed and store audio data using linear PCM (not compressed at all, neither using lossy nor non-lossy compression) at 16-bits/44.1 kilosamples per second per channel. That requires 660 MB per hour for two-channels of data. That's "CD quality." 24-bit/96 kilosamples per second requires roughly 2 GB per hour.

Well, you would be the specialist, but all I care is that I can fit over 100 songs on my 256mb Yepp Player.

[LorryDriver71]

What makes you think that cd quality audio is 64kb/s? Mabye it's because windows media player says that wma at 64K is the same as CD quality.

That is soooo wrong i think it's insulting towards Len.

Explain to me how this is wrong when I am looking at my Windows folder with all my music in it? If you can find the answer, shed the light, if not, keep out of it because what you said does not help in anything, its a pointless post!

[Thinkingmandavid]

I got an email from ecost and the 512 sd card is 134..not bad :wink:

OK, I'm not sure about the "insulting" part, but your answer isn't particularly helpful with regards to what Len is looking for.

Pure, uncompressed, digital audio is usually 176KB/s for a stereo 44.1kbps, 16-bit stream. That's 176 kilobytes per second. This is how CDs are encoded, and that's why a 640MB CD holds one hour of music. Up the sampling frequency to 48kbps, which is what most professional systems use, and you're upping your data rate to 192KB/s.

Lossless compression, such as FLAC (http://flac.sourceforge.net/), can perhaps trim this to 50% its size, or maybe about 100KB/s. That's roughly a 800kb/s bitrate.

MP3/WMA/Ogg/AAC are all lossy formats, by definition. By saying "CD-quality", Microsoft really means "it will still sound like the original CD even though you compress it". And it's not entirely true -- with a good set of headphones or speakers, you can easily notice the difference. It may not be significant for a rock tune, but for subtle music, especially strings, it doesn't come anywhere near professional audio.

An analogy is the use of BMP/TIFF versus JPG -- the latter will introduce noise into the image, since it's lossy, even though it gives you strong compression. (PNG's lossless compression is much like FLAC -- it's lossless, and in some ways is a good compromise if you want the original image but want to save some space.)

So, for professional audio, you need lots of space. Ergo the demand for 1GB and greater flash/magnetic media. Pointing out that 512MB and smaller are available isn't going to help, unless the professional enthusiast is willing to switch cards, which you generally don't want to do in a darkened performance venue; not only is there the danger of losing the medium, but the switch may come at an inopportune time and you might lose some of the performance.

for certain a lot of technical information.
YOu are getting your grad degree in what Janak? :mrgreen:

I just through in the price of the 512 because I thought it would be good info for those watching the posts :idea: 1gig sd card, great, price bad. room great, will it be enough for everyone? probably not. :)

Right, but it's really offtopic to this thread. Start a new Just Chattin' thread, or submit it as news.

[Kati Compton]

all of this music is not compressed and above cd quality audio (64kb/s)

BTW - another (non-tech) way to know this statement is not correct is that you're saying that the files you sampled from a CD are a higher quality than the CD itself...

[Shadowcat]

Honda probably has heard enough, but I can't help but providing another way of looking at it. From a logical point of view, a regular CD, with 650MB of space, can only hold 74 minutes of music or sound. How can you fit the same amount of music at the same sound quality on a 256 MB flash disk? All the "CD-quality audio" is market-speak. Granted, I admit I can't really tell the difference, but I use relatively low end headphones and I'm usually outside when I use them anyways. However, that does not mean that there was no compression and that it's true "CD-quality." Remember never to beleive everything you see and read. Ask yourself if it's logical!

Well, you can compress audio without loss of data, but it doesn't get nearly as small. I'm not sure what the theoretical minimum size would be for lossless compression of 650MB.

[Janak Parekh]

Close to 0 bytes, if you're compressing pure silence. ;) From what I've heard, though, typical compression ratios for FLAC are on the order of 2:1.

It was brought up how the 1gig would be expensive, and in contrast to that the 512 would go down in price. If for some reason those who are interested in the 1gig do find it expensive to purchase, I threw in that currently a 512 was 134 on ecost. A good way of seeing price to size ratio in thinking about if everyone wants to wait for the 1gigger :wink:
This did start out about 1gig sd card and then some people got off.

[maximus]

Hey, this is really strange.

Panasonic 512 SD in singapore is USD 200.
But in indonesia it is only USD 170.

Humm. weird.

[Thinkingmandavid]

I was at best buy and walked by a scandisk display and saw 1gig and was like oh hell sd cards, but upon second look it was cf cards. :|
Since this post I have been thinking of what I would do with so much room.mmm.

Just for the record...I think a higher capacity SD Card would be GREAT. I have a Toshiba 5GB attached to my h5555 via the Expansion pack. Though some might see it as over kill, they have no idea what a true mobile profession might need while out and about. For example, this is what I keep on the 5gigs.

- Videos of my daughters
- a few hundred MP3's (never know when you might have to jump from LA to Paris at a momments notice, or spend a few hours in a waiting room.
- A whole library of ebooks
- Recorded notes of my ideas to rule the know universe and beyond
- :D "Special" password encoded videos sent to me from my "Women" via webcam or their nokia 3600s to keep me smiling and happy all day long :D
- The hundreds of pictures i take sometimes in a day with my T616
- Along with all the documents, and email attachements I recieve while out and about.


as you can see, if they build a high capacity data storage device that is portable, WE WILL FIND AWAY TO FILL IT.

[BigDaddy]

And for the record, Honda_Civic my man, i am like you...all this talk about CD quality kills me. The fact is that most would not be able to tell the difference between the CD and a mp3 recorded at 128k if their life depended on it...trust me, bet this fool at the GoodGuys a Kenwood Music Keg. Needless to say, Mr. Sound expert was out a Music Keg when he discovered that if you know how to tweak the EQ the "HUMAN" ear can not tell what is what.

So keep posting my friend....~BD

Excuse me? 128kbps may be fine for casual listening, but for the professional who's trying to either capture multiple channels, or would like to have a pristine recording for editing/amplification/etc. editing lossily-compressed music is a recipe for disaster. If you've worked with Photoshop and edited JPEGs and saved the format back as JPEG, it becomes obvious. Very rapidly.

Moreover, live performances have a lot of ambient sound and other forms of white noise. Compression makes those sound like random artifact garbage.

Lossy codecs are great -- I have tons of music on my iPod in AAC -- but don't go pretending they're the same thing as lossless. :roll:

Although I wasn't directing my gentle (hence the :wink: ) correction toward you, I don't think it's a typo because I've seen thinkingmandavid say "Scandisk" before (http://www.pocketpcthoughts.com/forums/viewtopic.php?t=20004&postdays=0&postorder=asc&highlight=scandisk&start=10&sid=873faa7371172558a47b1e55db69d1d1). If I were him, I would want somebody to correct me.

[JustinGTP]

1. Sorry Spursdude, my mistake.

2. I dont want Bigdaddy and Janak arguing again! I am obviously wrong, but I am perfectly fine knowing that my music habits work for me, compressing and the kb/s per second.

3. This doesnt need to be a repeat of the thread that Kati locked.

4. You'll notice that I stopped replying in this forum when the nitty gritty came into place with the music expert (Janak) and I know it was out of my league, so I kept quite. Like I said, I know my habits are working for me and Ill stick with them.

[Thinkingmandavid]

Just got back from class, thanks for showing me my typos. I have been saying scandisk and yet I am not for certain why. 8O I think I started referring to it that way a long time ago because of somethign i read and got the two twisted. Thanks for the heads us :wink:

"Special" password encoded videos sent to me from my "Women" via webcam or their nokia 3600s to keep me smiling and happy all day long should we even ask 8O

what counts is how you use your ppc justin, i agree leave the technical stuff to janak on that issue :)

[Janak Parekh]

:oops: I'm not really a music "expert", guys. I just know barely enough to know why different choices exist. :) Len & co. are the ones who are truly the hardcore music guys, and it's good that someone is pushing the envelope of Pocket PC audio.
