FLAC is a container format and can both be lossless compressed and uncompressed PCM. WAV is "pure" PCM. So yes, you get the PCM data, whatever storage/streaming format. Your DAC deals with PCM and possibly DSD. It doesn't deal with FLAC. There is another component or subsystem upstream from the DAC that converts FLAC into PCM.
https://www.whatsbestforum.com/goto/post?id=848375By the way, I have compared several Qobuz downloads in WAV and FLAC versus CD rips and the same streaming content and found that, in general, Qobuz sounds really good. When comparing the FLAC download to the same streaming file, I consistently preferred the downloaded file (just slightly crisper and livelier), and also preferred the WAV version of the download over the FLAC version.
When comparing a streaming file to a CD rip, I usually preferred the CD rip, but this is tricky as you can never be sure that the source is 100% the same.
An interesting point to make here is that Emile is working on a software implementation that will greatly reduce the influence of the file handling property responsible for the audible difference between WAV and FLAC, and with that, also further reduce the gap between local and streaming. This has got to be frustrating for dealers who almost all use streamers. Recently I heard some speakers with a Bartok streaming from Qobuz. When I asked to try some tracks from a USB stick, the dealer nearly fell off his chair at the difference. Once you've heard the local WAV to FLAC difference in SQ, you can't unhear it.
I've found the delta in SQ to vary with system from clearly audible (ibasso dx300 portable in the car system) to significant to OMG.
I can listen to streaming only if I don't know what the local wav file sound like. If taiko can eliminate the delta in SQ, I'll be a happy camper, (as long as there are no gaps) When I had an Innuos Zenith MK II it provided ripping of CDs with its onboard CD drive in either FLAC or .wav format. I much preferred the SQ of .wav. But that might have been down to Innuos' hardware or software implementation of FLAC. We have also found that the average SQ gap between FLAC and WAV has been getting larger and more obvious as the Extreme has been getting quieter and quieter with the various updates to OS, USB Driver and music server software.
https://www.whatsbestforum.com/goto/post?id=848473local WAV >> local FLAC > streaming(flac) Playing back the flac files vs the.wav files created by the Innuos via the Extreme I still have a marked preference for the .wav files. i agree completely. on many tracks, the flac files sounds flat, 2D by comparison. that is consistent with what i've heard here, not a huge uptick for local WAV files. if it makes a big difference for streaming,
combined with a future narrowing of the flac/wav gap i might even like streaming MB--i just added the ellington to my test folder, then created a flac version. the difference is not subtle and you're missing a lot (imho) with the flac.........try a WAV version of the ellington track and let us know if you hear what i hear. I'm not sure why this has you bent out of shape. Systems are different as are listening preferences. Audio buds who have visited my house are unanimous that local wav is clearly preferable to local flac, listening to my speaker system. I find the differences even more obvious with a high resolution headphone, the stax SR-009. @cat6man graciously sent me some files with versions in .wav and .flac which I listened to at the time but did not report back (it seems I'm on a different continent every month). Some folks report obvious differences, but I did not find that to be the case for me. I'll give it another whirl when I get home again. Honestly, everything sounds so good these days it's an embarrassment of riches. I have listened to flacs and wavs of the same file sets
and did not hear a significant difference and definitely not enough to convert everything to wav. However, I don't doubt that others hear a difference. I got the same files from Marty and I did feel the .wav was not that noticeably better but my understanding is Marty is using a different tool I converting to .wav which has made the huge sonic improvement. I know Ed visited Marty last week and Ed reports that he was stunned as to how much better Marty's .wav files sounded in comparison to Flac , so much so that there are some plans to delve further into this and make it a reality for XDMS. Right now as I understand it in Qobuz the files are converted to .wav and that is what we hear presently BUT Marty is converting using a different tool which has caught the interest of Ed so thanks to cat6man it seems there we can all look forward to this being implemented The reality is that only Marty and his system demonstrate the difference. Ed visited Marty on Wed and confirmed that wav was truly spectacular and much better than FLAC. We undergo conversion to wav in Qobuz and even thst was done all of us heard the difference. However Marty’s was so impressive that it took Ed by complete surprise , so much so that he intends to delve into this with the hope that this can be implemented in XDMS. So once again kudos to cat6man. I know what Marty is using but I will leave it to him to post
http://jplay.eu/forum/index.php?/topic/3705-removing-file-properties-before-playback/Has anyone tried this? I first thought of it when experimenting between whether to break down an sacd iso into dsf or dff files. dsf has metadata capability. dff files do not. (Sonore's iso2dsd app let's you choose) So dsf seemed the logical choice, but JPlay Mini likes the dff files better. Less glitches, smoother performance, better sound.
So on a whim I tried removing the file properties from some large 24/192 wav files before playing them, and I got the same positive improvement.
So now my obsessive JPlay routine unfortunately has more steps: copy files to C:// , (keeping highlighted), right-click open properties, go to details tab, click "remove proprieties and personal information", choose second option "remove the following...", cut files to clipboard, open mini, close everything else, maximize mini, arrow click in empty area, hit space bar.

wav2w64 tool to convert wav to w64

假如有興趣嘅話不妨試試：
https://www.audioshark.org/goto/post?id=255146I believe it truly depends on the server and playback mechanism. I am ripped to WAV64 at 32/44.1 for Redbook CD. The sound difference on my music server/DAC combo was significant between FLAC, WAV and W64.
https://forum.audiogon.com/posts/1742865I have a Memory Player installed with JRiver and I ripped some cd's to WAVE 64, as Sam included some WAVE64 files on my unit and I really liked how they sounded, compared to the same albums I have on cd and WAV.
https://www.thememoryplayer.net/2016-featuresTypical use is conversion of entire libraries to a better sounding file type or format. For example, ALL lossless compression is highly jittered. The Resampler can convert, say, FLAC to W64, and dramatically improve its fidelity.
https://www.stereotimes.com/post/laufer-teknik-memory-player-mini/Songs added to your music drive from thumb drive aren’t processed nor auto-added to JRiver MC, so you need to process them with the Mini’s Upsampler to bring them up to 32-bit Wave64 format where the Memory Player’s software does its magic.
So, what was CP doing during our listening sessions? He was dropping processed Wave64 files onto ’Burn Memory’ slots in his Memory Player 32, then dropping that converted file into JRiver, and playing from JRiver. This provides a noticeable improvement over just playing from JRiver referencing the Music drive. |
