About: MusicBrainz Piccard is an official MusicBrainz tagger and music organizer that is written in Python programming language. Do they sound the same if set to bit-perfect output? Let's have a look at the candidates I'll be considering here:Supported Operating System: Mac OS X, Windows, and Linux. To play 720p HD video, an iTunes LP, or iTunes Extras, a 2.0GHz Intel Core 2 Duo or faster processor is required.Over the last few years, the list of "audiophile" audio players on the Mac has gradually increased. Apple iTunes was reviewed by Sergiu Gatlan. Apple iTunes is part of these download collections: Music Managers, Play M4B, M3U Player, Create Playlist.IINA is born to be a modern macOS application, from its framework to the user interface. Change log.For and only for modern macOS. When playing stereo on a multi-channel-only DAC, the two stereo channels are copied only to front-left and front-right, while the other channels remain silent. It fixes problems with ReplayGain, the proxy database plugin, and the playlistadd command.
Music Player Free Video PlayerListening digital music player for music lovers who use the OSX operating system.2. This video player Mac app delivers an outstanding HD experience without putting a strain on your CPU.Download Pine Player for macOS 10.9 or later and enjoy it on your Mac. Elmedia Player is a free video player for Mac that boasts compatibility with all commonly used video and audio formats, including AVI, FLV, SWF, MP4, WMV, MOV, MP3, DAT, FLAC, M4V, MPG, DivX and MKV. Memory playback was activated.The Best Video Player for Mac."Under the hood", it's also got some extra features like memory playback, "Direct Mode" apparently bypassing CoreAudio as well as "Integer Mode". Able to handle DSD files with DST and was able to play DSD64 and DSD128 over the USB interface to my TEAC UD-501 without problem. It's got a nice, fancy GUI. I bought this one about 6 months ago. Best msn messenger for macAlso, I have SysOptimizer turned on (disables Spotlight, Time Machine, some USB tweaks).3. The green "INT" indicator turns on. For these tests, I'm using Direct, Integer Mode with memory playback to the TEAC. They also talk about 64-bit processing which is great if one has need for the SRC and dithering (iZotope-based). Pure Music - I'm not as familiar with this one. It's capable of DSD playback to the TEAC using DoP.4. Bit-perfect from the start so I didn't fool with any of the default settings. I measured the beta 18.0.177 build for this test. TEAC HR Audio Player - Release version 1.0 for Mac. My subjective opinion is that I did not like the UI and using iTunes means no native FLAC support.5. "Memory Play" was activated for playback. Can handle DSD but I didn't bother trying since it looks like there were some contortions needed to get these files recognized under iTunes. It literally "wraps" around the iTunes interface. Does have an "Expand to RAM" mode which I did not use for these tests.6. Unable to decompress DST though. Will do DoP for DSD playback. Seriously, after 11 versions, to not support the universal lossless audio format is just stupid and has been a reason why I do not buy music from Apple.Over the years I have tried Play, Amarra, and Fidelia as well, but figure the above was enough to look at for a sense of the field out there around Mac music players. IMO, the other BIG negative about iTunes is that it does not support FLAC. The BIG negative about iTunes for audiophiles is the lack of automatic sample rate switching - need to go into the "Audio MIDI Setup" panel to change sampling rates and bit depth (yuck). Version 11 was released in November 2012 with some folks claiming volume and sound quality changes compared to version 10. A lot of uncertainly out there about this program with folks jumping up and down with each version claiming that sound has changed for better or worse. Should be "bit-perfect" so long as volume at 100% and none of the DSP plug-in's are activated. But I think I can say with some assurance given similar setups as mine that:1. DiffMaker has amplitude compensation so it is trying its best to compare the audio quality beyond the volume difference.Well everyone, unless I missed something obviously subtle here, what I see is that bit-perfect is indeed bit-perfect playing the audio through my TEAC UD-501 DAC with all these programs.Now of course I cannot overgeneralize these findings to all Mac computers, all DAC's, all player programs, all drivers, all DAC's, etc. Again, nothing fancy, just 2.2GHz AMD Phenom X4 processor toGrab data from the E-MU 0404USB and process the data through DiffMaker, RightMark, or jitter FFT analysis.Part I: RightMark 6.2.5 (PCM 16/44, 24/96, and DSD64)All the measurements done with the test signal encoded as FLAC except for those based on iTunes (iTunes, Pure Music) where AIFF was used.I found it quite remarkable the drop in null depth by just turning on the iTunes EQ plug-in and using it to adjust just 1 notch (don't know how many dB's this is supposed to represent) ! Pure Music -1dB volume control changed the measurement slightly but not much. Running OS X Mountain Lion with no OS tweak for audio.Win8 laptop is the Acer Aspire 5552 which has been my measurement "workHorse". From what I can tell, jitter is primarily a hardware property and software timing issues lead to obvious audio drop-out rather than subtle pico- or nano-second changes in the audio output.3. This is not surprising as I had already previously reported that I was unable to detect more jitter with increased processor load as some seem to believe. No evidence of anomalies in the Dunn jitter test signal. Subjectively with headphones attached to the DAC, I did not notice a difference listening to the music being played back while doing the DMAC Test.2. This is supported by every measurement method used. RMAA ?I agree with the findings and feel the tests are 'valid' but have the advantage to know what is actually tested and how it is. I just don't see any evidence that they sound any different.It is rather easy to find out how much correction one 'step' is in the equalizer. Beyond that, I'm happy to own both Decibel for its simplicity and flexibility in playing all kinds of formats as well as Audirvana Plus for the full feature set including DSD playback and DST decoding. The MAIN feature over iTunes is the ability to automatically adjust the sample rate. I see no evidence that special features like memory playback, "direct mode", "integer mode", "SysOptimizer" made any difference compared to the output from the no-frills TEAC player where I did not even turn on the memory playback feature with the 2008 MacBook Pro.Bottom line is that these programs work well to output bit-perfect audio. Still waiting for more DSD content for this to matter. The few that a tested were never able to prove what they claimed (and still claim) they CAN do. There is always an excuse mostly about 'familiarity with the system', 'not revealing enough system' or 'pressure to perform' which seems to be able to, temporarily, completely loose the ability to discern, the otherwise always clearly present, differences under these (or other) flags. The test is flawed or does not reveal what determines SQ simply because there is 'something or some aspect' the ignorant technical minded people do not KNOW about (yet) and drag in the middle ages and what they thought they knew back then and how wrong they were knowing what we know now and stating we still have LOTS to learn.So when subjectivists get wind of this blog they will disregard all that is done here based on:A: They believe the quite obvious differences can not be measured (yet).B: Subjectivists (especially the < 1 ps jitter crowd) believe the changes they can perceive are in the -130 dB region and the measurements appear to differ in the -90dB region already.C: Subjectivists always trust their ears over any instrument.The list of excuses is endless and replies to Mitchco's en NwAvGuy's attempts are living proof of it.It is too bad none of these golden ear oriented characters can actually demonstrate what they claim they in front on a less subjective person that tests them. I think (hope) it's a matter of education. I might have a look next week after my vacation :-)Agree on the general audiophile-folk comments. For a lot of 'objective minded' audio-aficionados that sometimes doubt if, what subjectivists say with such conviction, might actually have some truth in it or think they might not have the same hearing abilities/gear as 'them', these tests might give them a push in the back.Yes, RIAA would show what the equalizer did. A well performed control test always proves that not to be the case. Stress ?Of course I can't discern differences when testing blind but sometimes think I hear differences when testing sighted. I'd probably have better luck with the evangelists that come by my door once awhile. I do appreciate John Atkinson's measurements in Stereophile and see his measurements section as absolutely the most useful portion of the magazine.Imagine where we would be if all of engineering were performed without properly controlled tests!I *try* to avoid arguments with hard-core subjectivist folks.
