"BBC is biased towards DAB" wrote in message ... "Serge Auckland" wrote in message loads snipped Internet radio on a mobile 'phone will be all about portability and choice of channels, audio quality won't be an issue, so streaming at 32kbps or less is quite likely. There are over 8,000 Internet radio streams on shoutcast.com using 128 kbps or higher, and a third of all UK commercial radio stations are using 128 kbps. Don't see why you think 32 kbps will be common for Internet radio streams, to be honest. -- Steve - www.digitalradiotech.co.uk - Digital Radio News & Info The adoption of DAB was the most incompetent technical decision ever made in the history of UK broadcasting: http://www.digitalradiotech.co.uk/da...ion_of_dab.htm Perhaps it won't but what I'm saying is that mobile broadband internet radio will become more popular than portable radio receivers, whether AM, FM or DAB. 60% of all radio listening takes place at home though, and there's no point in listening to radio via mobile broadband when you're at home (assuming there's a fixed-line broadband connection). If adequate quality for the purpose is available at only 32kbps, then bandwidth is no bar to this developing. 32 kbps isn't adequate, though. -- Steve - www.digitalradiotech.co.uk - Digital Radio News & Info The adoption of DAB was the most incompetent technical decision ever made in the history of UK broadcasting: http://www.digitalradiotech.co.uk/da...ion_of_dab.htm |

"BBC is biased towards DAB" wrote in message ... Internet bandwidth costs fall in-line with Moore's Law, because Moore's Law increases the speed of Internet routers without increasing the costs of the routers. Frankly Steve, if you can write something as naive as that, your opinion isn't worth bothering with. Suffice it to say that internet costs are more to do with transmission systems than routers, and that is particularly true of mobile internet. I meant Internet bandwidth costs for content producers. Have a read of this section if you don't believe me: http://tinyurl.com/5bzosx I'm not in any way suggesting that the cost of mobile broadband is linked to Moore's Law. Spectral efficiency on mobile systems can be increased though, because the new 4G systems such as LTE and WiMAX are using MIMO, and the 5G system when it's chosen will use MIMO in a big way - MIMO allows the channel capacity to be multiplied by the number of antennas used at either end of the link. There's a 5G prototype system that uses 12x12 MIMO, and that literally has a capacity that's 12x what it would be using single antennas, and it's been demonstrated transmitting at 5 Gbps to a moving receiver - in a 100 MHz channel. We obviuosly won't see those speeds ourselves, but it shows what the technology is capable of and the incredibly high spectral efficiency is allows. -- Steve - www.digitalradiotech.co.uk - Digital Radio News & Info The adoption of DAB was the most incompetent technical decision ever made in the history of UK broadcasting: http://www.digitalradiotech.co.uk/da...ion_of_dab.htm |

No, YOU are the one making the claims, so the onus is obviously on you to prove them. So there we go. You can't pass a simple listening test, and you now realise that you have just foolishly disagreed with a whole raft of well known and accepted truths. Competence isn't exactly shining through is it? But I am happy to get the ball rolling. 1. Classical music is more complex and demanding than modern pop. First, it is longer - that demands a greater concentration span. Second, it is generally written in several movements in varied time signatures, as opposed to modern pop, which is typically in a simple 4/4 or 8/8 signature. Third, it makes great use of interpretive rubato - something which can't be done with a pop tune locked to a click track. Fourth the harmonies are varied and often not those which would immediately suggest themselves. Contrast the simple thirds and fifths of pop music - when there are any, that is. Fifth the performance must be great because unlike pop, vocoding devices to bring the performances back in tune can't be used. 2. The CD has more definition than the human auditory system. Frequency range - the CD is flat from 0Hz to 22kHz. At normal listening levels, human hearing is down about 20dB at 20Hz and 20kHz. Linearity - The CD has vanishingly small distortion over almost 100dB of dynamic range. Human hearing is only marginally linear at mid frequencies, and heavily expansive for treble, and particularly bass. Resolution - the CD has effectively infinite frequency resolution. The human ear suffers masking, resulting in the ability to hear low level sounds close in frequency to a high level one. 3. It is not easy to compare CD and SACD. The DACs are not the same, so accurate levelling is not simple. They do not go through the same mastering process so there is no like-for-like material available to make the comparison. 4. Developments since the CD have not improved audible quality. The answer to 2 above already demonstrates this, but to see the truth of this you need only look at what the developments are. MP2 - a compressed version of CD, therefore by definition not better. MP3 - ditto AAC - ditto Minidisc - ditto I think I will leave that there. OK - I'm done. Now time for you to put your money where your mouth is and demonstrate that all of those are false. d |

Second, it is generally written in several movements in varied time signatures, as opposed to modern pop, which is typically in a simple 4/4 or 8/8 signature. This proves nothing. Third, it makes great use of interpretive rubato - something which can't be done with a pop tune locked to a click track. You said: "it takes a greater degree of intelligence to understand and appreciate it" When are you gonig to get round to the "intelligence" bit? Wouldn't happen to be because you can't prove that, would it? Fourth the harmonies are varied and often not those which would immediately suggest themselves. Contrast the simple thirds and fifths of pop music - when there are any, that is. Fifth the performance must be great because unlike pop, vocoding devices to bring the performances back in tune can't be used. See above. Overall: FAIL 2. The CD has more definition than the human auditory system. Frequency range - the CD is flat from 0Hz to 22kHz. Is there an infinite transition bandwidth at 22 kHz? That's an impossibility, because it requires non-causal filters which require an infinite number of filter taps. So what figure are you actually claiming the bandwidth is for a CD? At normal listening levels, human hearing is down about 20dB at 20Hz and 20kHz. Does psychoacoustic theory actually make any claims such as "nobody will have hearing above X kHz" and other stuff like that? At best, everything's statistical - all the psychoacoustic models have to be statistical, becaue they can't exactly have measured every single person's hearing on the planet. This implies that nothing can be proven with absolutely certainty - so the very best you can say is that you're X% certain of Y being true based on statistical analysis. Overall: FAIL Linearity - The CD has vanishingly small distortion over almost 100dB of dynamic range. Human hearing is only marginally linear at mid frequencies, and heavily expansive for treble, and particularly bass. Can you prove that no-one can perceive the difference between 16 and 24 bit? Obviously not, so FAIL. Resolution - the CD has effectively infinite frequency resolution. The human ear suffers masking, resulting in the ability to hear low level sounds close in frequency to a high level one. You can't prove this. FAIL 3. It is not easy to compare CD and SACD. The DACs are not the same, so accurate levelling is not simple. Is it impossible? If it's not impossible then FAIL. They do not go through the same mastering process so there is no like-for-like material available to make the comparison. Is it possible to master a CD that is to all intents and purposes a 44.1 kHz 16-bit version of an SACD or whichever other high-resolution audio format? If so, then FAIL. 4. Developments since the CD have not improved audible quality. The answer to 2 above already demonstrates this, but to see the truth of this you need only look at what the developments are. MP2 - a compressed version of CD, therefore by definition not better. MP3 - ditto AAC - ditto Minidisc - ditto I think I will leave that there. Since the CD came out, there have been attempts to provide higher audio quality, which you cannot prove do not provide higher audio qulaityu than CD does. All you're doing is using the circular argument that because *you believe* that the CD is slightly overspecified wrt human hearing then it doesn't allow trhe quality to be improved upon relative to CD, therefore any attempts at designing new audio formats will either be no better than or worse than CD. There have been formats that deilver sound quality below CD, therefore your circular argument has it that the only developments have led to reductions in quality. However, you have failed to prove that humans can't perceive any improvement relative to CD, therefore this and all the other claims come crashing down in a big FAIL FEST. Overall: FAIL. OK - I'm done. Now time for you to put your money where your mouth is and demonstrate that all of those are false. Done. Your turn. The reason I chose the quotes I did was because I knew you *couldn't* prove them. The best you could possibly do is argue the case, but theyr'e actually unprovable, so I couldn't lose.
