Listening Comparisons For Audio Codecs At 64kbps
waaka! writes "Hydrogenaudio has just wrapped up a listening test of various audio codecs at 64kbps. Check out the results, where Ogg Vorbis performed quite well, scoring significantly better than WMA, RealAudio and QuickTime AAC, and kept pace with MP3Pro and HE-AAC (AAC with the SBR extensions that MP3Pro uses). Clearly, though, no codec can honestly claim 128 kbps MP3 quality at 64 kbps. The charts at the end show entries for 128kbps LAME MP3 and 64kbps FhG MP3, but these are used as high and low anchors for reference, as MP3 is really out of its league at bitrates such as these."
... "Why not just encode it at 384 and be done with it?", consider that PDAs have 64 megs of RAM, cell phones get no better than 56k, and that not everybody has broadband.
"the purpose of PDAs is not to play music "
Yet they do, and people like to use them for that. Fascinating.
"the purpose of cell phones is not to play music"
Yet the holy grail of mobile computing is to merge the PDA (which can play music) and the cell phone.
You may like carrying around a cell phone, PDA, and iPod in your pockets, but I want one device that does it all.
Its nice to see ogg doing well, but ogg needs to start advertising. Nobody is going to give a shit about ogg if computer companies (apple) is distributing aac and their old napster mp3s don't play on an ogg player. Fact of the matter is that there is a LOT of power behind the MPEG (4, 7, 21) movement.
Have you seen the cuidado project? Have you read what companies publish? Why fight the good fight if you aren't getting the public hooked on it while its still the best option.
hmm

I want to give full respect to the people who put all the research into creating these new audio formats. The results are truly phenomenal for 64kbps codecs. It's a fabulous academic demonstration.
However, each is what it is. A 64kbps codec.
I have about $6000 invested in my 2-channel +subwoofer setup here at home, and I consider that moderate compared to what you can truly achieve. I love listening to music, and it is completely remarkable when it is reproduced as realisticly as possible. So I go to painstaking methods to make sure the AC power is clean, the wiring is right, the distortion is low as possible. The signal to noise ratio is far between, with a good amp, and great speakers... I am especially pleased when the recording I am playing on my wonderful system is in the best production quality that it can possibly be.
As amazing as they are, these 64kbit formats are useless on a person like me. I crave LOSSLESS not LOSSY. I might as well be listening to music on a $60 AIWA boombox, since it would sound relatively similar either way. All the subtle beauty and realism of the music is completely wasted with destructive compression.
And for those of you that say it's for portable devices, It's not too unreasonable to get a portable player that plays high streaming VBR mp3s with some nice ~$100-$150 headphones. The small little investment to hear your music from 20hz-20khz flat response with low distortion is worth every single penny.
I simply do not understand the need to take our ever improving technology and lower the quality of the music. If anything, it should be increasing... higher resolutions. 24bit/192khz technologies, and wonderful DSP equalizers, large portable storage devices... they are all realities now, but nobody seems to care but the fanatics like me. I would think that techno geeks would care more about the music they love, but that does not seem to be the case. The only logic that I can fathom to explain why is that perhaps they don't even know what they're missing. I know I didn't, until I actually experienced how good sound quality can be on the right system.
