Thomson og Fraunhofer har introdusert et nytt filformat, mp3HD.

Men hva er egentlig nytt? Nyheten sammenlignet med det tradisjonell MP3-formatet er at mp3HD støtter tapsfri kompresjon. Men det gjør forsåvidt allerede både FLAC, Apple Lossless og diverse andre. Så, ingen nyhet. Formatet støtter ikke en gang samplefrekvenser  over 48 KHz og maks bitdybde er 16 bit per sample. Så det støtter faktisk ikke 96/24 eller høyere, i motsetning til de fleste nye formatene introdusert med bl.a. Blu-ray – er det da HD?!?

Kompresjonsfaktoren er omtrent den samme som for FLAC, 50% +/-, så ingen forbedring her heller.

En annen egenskap ved mp3HD er at det er bakoverkompatibelt med MP3. Det betyr at den faktisk inneholder a tradisjonell MP3-file, slik at en god, gammel MP3-spillerkan spille de nye mp3HD-filene. Da selfølgelig med ”MP3-kvalitet”, ukjent ved hvilken bit-rate. Filene vil uansett bli ganske store, omtrent tre ganger større, sammenlignet med tradisjonell 320 Kbps MP3.

So, what’s the point?!? 

Jeg holder meg fortsatt til FLAC!

HDtracks is a new online record store offering DRM free downloads of uncompressed music. Currently they are offering AIFF, FLAC and MP3 (320 kbps), which means its files are compatible with all digital players, and they even they plan to extend their offer to also include downloads in HD, meaning 24 bit/96 kHZ, which match the quality of DVD-Audio. I really need to buy the Slim Devices Transporter soon…

The catalog of HDtracks is currently quite limited, but it holds some titles of i.a. Henry Rollins Band, Ray Davis and The Kinks, Norah Jones, The Byrds and some other interesting artists. The price charged for a complete album is $ 11.98 which is quite reasonable.

I’ll test it out as soon as I get home to my Squeezebox. You should test it out too at www.hdtracks.com.

Update:
Unfortunately, I just realised that HDtracks offer their dowload services  to US citizens only :-(

After spending several hours ripping my CDs and storing them in my basement I finally thought I was rid of them. But no! In my search for new music to my collection, I can hardly find any web shop offering music download in a lossless file format. Most shops offer MP3 or WMA. The only legal sites for downloading FLAC I can find is Metallica Live and Nine Inch Nails album Ghosts. Thumbs up!! The rest of music industry; get a grip!

So I guess I still have to go to my local record store to buy the CD, just to rip it and put it away…
