-- Better than MP3 player!!? (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=12961)

better than MP3?

check this out. IT IS NOT SB MODULE, but Hagiwara Sys-Com, that same guys making 16/8MB and new Stepkeeper module, selling this "Solid Audio Player" (or "IC sound player") thing named SD-1. (www.hscjpn.co.jp)(don`t go to English pages, they don`t have it there)

this could be a bomb if it become a SB module, you know? why? well check the spec.;

-size of business card with about half inch thickness
-using TwinVQ tech. (will be used for MPEG4/Audio)
-three play mode. -high quality/sampling freq.=44kHz
100min./64MB
-standard/22kHz 200min./64MB
-long play/11kHz 400min./64MB
-Smart Media with "ID"(for copyright protection. you cannot
use regular SM) 8MB-128MB

take out battery from this thing, you have new Audio Player module with longer play time or better sound, right??! I didn`t care much about MP3 somehow, but 400min. of play time?! or 44kHZ!?(whatever that means it looks so good)
this might be good... NTT(DoCoMo,or i-mode)is part of the developing team, meaning it might show up here soon through AT&T...

hey, what you think people?

u-key

I have to admit that I not enough of an audiophile to know whether I would accept 400 mins of 11khz audio. Going from my MP3 experience, that only seems good enough for "spoken word" type applications, like audio books. I would think there would be too much distortion for music, although 100 minutes of 44khz in 64MB doesn't sound too bad.

Like I said, I don't know much about the difference between 11khz and 44khz, I just know my MP3's have to be 162kbps or higher, or it drives me nuts.

Wherever you go, there you are.

There is a sound law (dunno the name) that says to get the most accurate sample for music, then you have to take it at double the highest frequency that you want. Since the human hear can generally only hear up to 22kHz, you gotta sample at 44kHz to get a nice progression and make it sound smooth. So audio CDs are sampled at about 44kHz (2*22kHz). I agree that 11kHz may not sound as good or have the range.

More or less to my understanding:

44kHz is equatable to cd quality.
22kHz is more like a cassete tape.
11kHz is the equiv of the quality
of connection that you get talking on a phone.

The guage in kHz is for freq. varience in the
sound waveform; Like the graphic eq on your home or car stero. The listing in kbps is simply the sample rate. Esencally determining how and how thorough the data contained in each second of the recording is.
