In Reply to: Re: Trying to play and transcode 32bit 88.2Khz files posted by Tuckers on February 11, 2007 at 02:38:52:
I didn't think 32-bit integer is a valid profile for Windows Media lossless (i.e. you can't compress at that resolution)I suspect they are 24-bit (but stored as 32-bit floating point - with 8 bits for exponent), in which case they will play fine on WinAmp.
I'm currently experimenting with converting DSD to 88.2/24, and I'm planning to use WinAmp to play them.
Follow Ups:
I suspect you are right, as I am getting ambigous results. Some programs say they are 32 bit, and some say they are 24 bit. But programs like Samplitude are automically downsampling them when I open it, because they don't support 32 bit.
Read up the specs on Windows Media Audio lossless.Basically, WMA Lossless is not a "universal" encoder/decoder, ie. it does not support all sample rates and bit depth, only the ones predefined in profiles.
WMA 9.1 (as distributed in Windows Player 10) and below only supported a very limited number of profiles. For example, you can encode 5.1 channels in 96kHz 24-bit, but not 88.2kHz for example (although 2ch is supported).
WMA 9.2/10 (as distributed in Windows Player 11) supports a greater number of profiles, but as I recall it doesn't support any 32-bit profile (but I could be wrong on this).
Anyway, you should be able to decode these files back to WAV (Microsoft has a command line decoder you can download) or use a program like dbPowerAmp (latest release R112 supports WMA10).
Plus, as I've said before, WinAmp should be able to play these files back at 24-bit resolution.
When you load them into meda player and look at the properties it reportsWindows Media Audio 9.2 Lossless
VBR Quality 100, 88 kHz, 2 channel 24 bit 1-pass VBRWhen I convert it with Jriver Media Center it comes out as a standard 24bit / 88Khz wav file.
However, this is only for the test tracks and I thought that Linn is only selling these hidef tracks with DRM on them and at that point you can not decompress them to WAV. Does anyone know for sure?
Cheers
Linn is selling these tracks without DRM, they say they WANT users to convert or decode them as they see fit. I think this is because they know that many users may have to transcode them and downsample them to be able to play in things like iTunes.
Right click the WMA file in Windows explorer, select Properties, then the Summary tab, then click on Advanced. The information window will confirm that the files are WMA Lossless 88.2kHz 24-bit resolution.I think Linn says on the website that they don't apply DRM on the download files that they sell.
