The concept behind memory playback is that any activity going on inside a PC generates some electrical noise, be it RFI, EMI, ripples on the power rails.
If there's a difference John will find it, that's his job.Īll most all I/O in a computer is buffered. He has a huge lab full of MHZ scopes and network analysers, it'll take no time at all. He's an audiophile I'll have him have a look at the USB output and see what the difference is between BP and vanilla Itunes. I'm off to Cambridge on Tuesday to see a mate who work at ARM in their RF lab, I used to work with him at another chip design house on the science park. Maybe it makes no difference with my dac, it seems pretty unaffected by such things, Decibel, Audiovarna, Amarra etc. I have tried them back to back, and I didn't find it sounded any better than itunes. I stand corrected, I assumed it just piggyback PAI calls from itunes and locked out coreaudio. I expect, if you tested BitPerfect against iTunes with the sample rate set correctly you would still find BitPerfect to have superior sound quality. After those basic things come memory play, optimizations for gapless playback and whatever secret sauce each player uses. The first things to be done when making an audiophile music player are sample rate switching and exclusive mode. WMP) then I'd suggest the AoS digital-audiophiles collaborate and send a feature request in for a future Lion update, pointing out that the competition does it already :)Īs the guy who wrote it, I'd object to that. If it does turn out that Win7 does this in native sound playback software (eg. However, you'll have to state which software you're referring to. My Mac's in bits just now, but when it's back up and running I'll have to test your hypothesis that the Win7 native audio software changes the output bit-depth and sampling frequency on the fly. Ok, so it's not available for QuickTime or iTunes by default, but at least the feature is available in the API, otherwise a 3rd-party programmer wouldn't be able to implement it in a MAS-approved app. What happens when you have more than one source playing at the same time? For example, a game in windowed mode and the TV in another? Which one takes precedence? Is this controlled manually or automatically? And there's the small matter of it being 1/33rd of the price!īut this feature has been broken for years. The playback position is kindof messed up with Pure Music. It's a smaller footprint piece of software, and it allows better control of itunes. The itunes integration is better than that of Pure Music.
Don't get me wrong, I wish that it would. Maybe the "BitPerfect" software is mangling the 24/96 material? Again, I don't see why it should be.īut for some reason, it just isn't floating my boat. Maybe the 24 bit output from Channel D is what's making it sound better than the £2.99 software, but again, I can't see how. I have Channel D outputting 24/44.1 or 24/88.2 - can't decide which I prefer, or if there's a difference, but I *think* the 88.2 sounds better. Everything seems just a bit more muddled and veiled. But for whatever reason, it doesn't seem to have the same sense of space and openness. So for CD's at least, it definitely is outputting 16/44.1 bit perfect.īut, for some unfathomable reason, this software just does not seem to sound as good as Channel D's Pure Music, especially with 24/96 material Whether that's psychological - or wishful thinking! - I just don't know. And my only DTS CD rip plays music not noise. And the HDCD light comes on with appropriate material too. One of my DACs (one that displays the input frequency) clearly shows 44.1 or 96KHz as I switch source material. The software would appear to work fine too. And then 1 hour ago, I find this for £2.99. Having pondered for a while on whether to fork out £100 for Channel D Pure Music, yesterday I took the plunge and bought the software. Well, interesting timing if nothing else! Some people think that business is like war - only losers play fair! I'll draw a veil over how some companies (possibly the same one/s) have tried to kill off competiton when it suited them. Maybe, but some other well known companies have managed to sell their systems with software which is incomplete, difficult to use, and sometimes totally rubbish, and then competition in the software arena has gradually brought something close to sane solutions to be made available. I guess your issue is that Apple "should" be providing software with this functionality already. How much is the Bit Perfect app? I can't find out right now as currently using an iPad. Not sure, maybe it really does depend on price. When I think of the price these computers cost, I can't help going :steam:
Am I the only person on Earth being shocked about the fact that Apple lets third party companies charge $$ (be it £2.99 or whatever) for an essential (core) digital reproduction feature.
