jonnyc Posted February 16, 2003 Report Share Posted February 16, 2003 im wondering if i record on the sharp dr-7 and then occasionally play it through my sony will those extra 8 bits be negated when the sony reads the data ? or will it actually up its processing to a 24 bit stream ? mainly will the quality be just as good as if i recorded a disc with a sony recorder ?

Mystyler Posted February 16, 2003 Report Share Posted February 16, 2003 Yes, I doubt you'll notice these days. All newer models sound virtually the same, so it won't matter what unit you use to record. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 16, 2003 Report Share Posted February 16, 2003 thats good to hear! it does interest me though. Does anyone actually know how the sony player will deal with the overloaded bitstream ? or how a sony recorded disc at 16 bit is handled by a sharp player excepting 24 bit.

BJ Posted February 17, 2003 Report Share Posted February 17, 2003 I always thought the bit rate was just to indicate what the machine used to record the sound, convert to ATRAC, etc. Once it's recorded on the MD, it'll be the same signal when it's read back, no matter what player you're using. Supposedly, though, the 24 bit machine would have recorded a cleaner sound that would be heard on any playback machine. I dunno. Am I making sense?

Mystyler Posted February 18, 2003 Report Share Posted February 18, 2003 There was a long and detailed post about 24 V 16 bit ATRAC around here a while ago. If you won't, try a search. I'm too lazy to do so now. Quote Link to comment Share on other sites More sharing options...
me Posted February 18, 2003 Report Share Posted February 18, 2003 24 bit I think is more accurate, like... 0.123456 is more accurate than 0.1235. Of course, it's in binary. I'm not sure how noticable this all is - at any rate I cannot tell the difference between my Sharp ATRAC 8 24 bit and my Sony ATRAC 4.5 16 bit.

Guest Anonymous Posted February 18, 2003 Report Share Posted February 18, 2003 that doesnt make any sense. It cant be all read the same, the way recording works is it takes a "picture" so to speak of the sound wave ten of thousands of times per second. The 24 bit recording uses 24 bits to record each picture of the soundwave, 16 bit recording only uses 16 bits. The bits are read in either 16 bit or 24 bit packages. Now sayingthat you cant tell a difference is like sayign you cant tell a difference between MDLP and SP mode becuase 16 bits is about 2/3 of the info of 24 and MDLP is 1/2 of the info. anyways it would be awesome if someone could answer this, writing it off as not noticeable is really not what im looking for here.

MDX-400 Posted February 27, 2003 Report Share Posted February 27, 2003 24 bit I think is more accurate, like... 0.123456 is more accurate than 0.1235. Of course, it's in binary. I'm not sure how noticable this all is - at any rate I cannot tell the difference between my Sharp ATRAC 8 24 bit and my Sony ATRAC 4.5 16 bit.Are you sure about that Me??? I'm pretty sure almost all Sony ATRAC 4.0 and above utilise "Wide Bit Stream" which is either in 20 or 24 bit versions, right? In any case, this is just like CD... The MD can only record ATRAC in 16-bit (right?), but the 20 and 24 bit business is all about the ATRAC encoder/decoder, right? Then you have the D/A converter which can also be either single bit or multi-bit and in 16, 18, 20, and 24-bit varieties. I understand the basics of the digital filter and quantisation and all that and how multi and single bit D/As operate but I'm not so clear on how these more-than-16-bit ATRAC converters work. I'm thinking it is somewhat similar. But Sony does boast that "Wide Bit Stream" has better sound quality... Roland M. Quote Link to comment Share on other sites More sharing options...
BJ Posted February 27, 2003 Report Share Posted February 27, 2003 I'm sure Sony would claim a shoe has better sound quality if they were trying to market one. :wink: I honestly don't think it makes much difference these days. All I can tell is that Sharp tend to sound 'crisper' and Sony sound 'warmer'. Quote Link to comment Share on other sites More sharing options...
RISKBREAKER Posted April 23, 2003 Report Share Posted April 23, 2003 I don't know how atrac works exactly, but when you digitze an analog signal with "analog to digital converters" (ADCs), the accuracy is given in bits. For example: 1.) adc 8bit, 2^8=256 steps, so an amplitude of an signal could be digitized in 256 steps. 2.) adc 16bit, 2^16=65536 steps, higher accuracy than 8bit. So when you want to reproduce the signal, with an digital-to-analog conveter, up to 100% you would need infinite bits. Thats for "normal" adcs, i dont know how atrac works in detail, i thought i have read something about that atrac splits the frequency bandwidth (2-20000Hz) into 3 bands,but i dont know if atrac does that digital or with 3 seperate adcs. Hope that could help you(iam not good in explaining things in english), cya mike :roll: Quote Link to comment Share on other sites More sharing options...
