I thought I would share how I have solved problems that I have had when converting large, multi-channel .wav files to .flac files as well when trying to merge multiple large multi-channel .flac files into a single one. An example of the first case is converting the last movement of the Mahler 2nd. An example of the second case is creating a single file for the Eine Alpensinfonie in order to allow gap-less playback. In either case, the conversions were either failing or resulting in .flac files with a track length attribute of 0. On my Windows 10 computer, I have being doing the conversions using flac.exe directly and foobar2000. I have been doing the merges using foobar2000. I think the problems were being caused by limitations of the 32bit versions of flac.exe when processing files larger than 2Gb. When I replaced flac.exe and metaflac.exe which resided in C:\Program Files (x86)\FLAC\ with the 64bit versions in flac-1.3.2, both of my problems went away. All conversions also run much faster than before. (My DLNA setup is a ReadyNAS Ultra 6 running ReadyDLNA and Logitech Media Server, BubbleUPnP on an Android tablet and an Oppo UDP-203.)

I would like to reform the way I listen to music today and migrate to a Roon platform. What's holding me back is that I don't understand if I can have endpoints that can implement FIR crossovers and output over a multi-channel DAC, the way I do it today with JRIVER convolving filters created with Audiolense. So let's say my bedroom system consist of a pair of 2-way active speakers, where each of the 4 drivers is driven by its own Class D amp, which amps in turn are fed by a multi-channel DAC (like the miniDSP U-DAC8) connected to a NUC running Win 10 and JRIVER for convolver duties. Today, this is a DLNA endpoint (through JRIVER) but it is my understanding that this doesn't work with Roon, where Roon needs to own the queue and the endpoints are stupid. So how could I achieve this with Roon? Convolve at Core/Server level rather than at endpoint? I know Roon can convolve but can it convolve multiple filters and streams for different rooms/endpoints in parallel? Can Roon even convolve a stereo signal into a multi-channel signal or is it limited to stereo output only (i.e. room correction but no crossovers)? Do I need to involve HQplayer somehow? Ideally, I would like to use RPi 3/DietPi/Roon Bridge endpoints but I doubt they would have the CPU power to convolve say six channels of 131k tap FIR filters. Even if the Roon Server could convolve, is RPi 3/DietPi/Roon Bridge compatible with any multi-channel USB DACs? What about Signalyst's NAA instead of Roon Bridge, does that change anything? Or could I just install Roon Bridge on a Windows 10 NUC and use JRIVER WDM output to a multi-channel DAC? If that's the only way, I'll go with that, but it's just not a very elegant solution....

Hi Everyone, I'm thinking of getting the U-DAC8 ($250, the only 8ch USB DAC under $3800) for my HTPC and buff it up with goodies (up to ~$1500) which I could still use when a better option for a DAC would come along. Thought it would be fun as a project to see how a low-end DAC could benefit from high-end PSU and USB interfaces. Options I had in mind: tX-USBexp (sPS-500) --> U-DAC8 (LPS-1.2) - $1,250 PC --> tX-USBultra (sPS-500) --> U-DAC8 (stock) - $1,685 tX-USBexp + sCLK-48 (PC PSU) --> U-DAC8 (LPS-1.2) - $1,477 other? What do you think?

Greetings all, An article on the AudioStream website which might be of interest to those of you who enjoy high resolution 5.1 channel surround sound music releases: World's First Dolby TrueHD 5.1 Downloads Coming Soon! | AudioStream Regards, Mister Wednesday

Hi all, I've built a quiet pc for my video and audio library and am quite happy with it with exception of the sound card and am wanting to upgrade it. The setup is: it runs on windows 7 64bit on a SSD (fast boot time) it is currently is hooked up to 2 pairs of B&O BeoLab 3 and a Velodyne subwoofer (ie all active speakers) via Creative Audigy 2 Platinum (yes not the best). I will add a centre speaker once I decide what to get. I use XBMC but am trialling JRiver Media Centre with an Andriod tablet for 2 way remote. This pc will one day drive a 84inch TV (when the new LG or Sharp LCDs finally get to Australia) I was wondering if I could get some recommendations for a great multichannel soundcard (for movies) for less than 1k. I considered adding DAC but its rare to find a mulitchannel DAC and I'm not sure if its feasible to run 2 DACs for front and rear. FYI the BeoLab 3 are great speakers (to me anyway), very detailed, neutral with high clarity and I would like to get something that would do it justice. FYI my requirements are: great sound stage,details - hopefully approaching Linn audio products. I listen to classical music, pop etc plus love movie multichannel (5.1 is enough) PCI Express windows 7 support for 192KHz @16/24bit minimum number of power supply i.e. prefers not to buy a prepro/AV receiver My current shortlist are: RME HDSPe AIO with the analog expansion card Asus Xonar HDAV1.3 Deluxe with H6 daughter card Asus Xonar HDAV1.3 Deluxe with H6 daughter card with OPamps on the h6 swapped to Burnson HD Audio Opamp I would greatly appreciate any recommendations. Also any comments on how pro audio DA converter (eg RME) sounds and work in multimedia consumer environment would be much appreciated. Kind Regards, William

The home I just moved into is already wired for stereo sound in 6 different rooms, and I have the corresponding speaker wire coming out to one centralized location (each of the 6 zones having separate stereo wire). I want to: 1) Locate the source of my music at that centralized location. 2) Control audio playback in the 6 zones via a mobile app. 3) Have independent playback in each zone, and play multiple zones at once (either same audio or different) 4) Do the above with the minimal amount of new equipment/cost Current Setup/Equipment: I currently have just a 2-channel hifi stereo setup for playing lossless music files, described below: External HDD hosting music files> Windows 7 PC running JRiver> MusicHall DAC> Rega Mira Amp> 2 Rega Speakers I use JRiver Media center as my front-end and would prefer to do all of the above in JRiver, but would be fine with using different software/app to control/host playback of the music to the 6 zones. Can anyone here provide me with some insight/suggestions? I have called a few home stereo consultants and retailers such as crutchfield/best buy but all they do is push the sonos stuff, which is really not a great fit for me. Thanks in advance for any help!
