![]() I suspect I won't, but it will be an interesting experiment. In fact, I keep meaning to turn off BitPerfect and do some listening to see if I can hear any difference even in a sighted/biased comparison test. Even with non-integer conversion (like 44.1 to 96) it's not likely to produce any audible effect. However, thanks to and others, I have become a lot less concerned about sample-rate conversion since I became a member of this site. I used to be very concerned about this, and as a result purchased the $10 BitPerfect app, which sits between iTunes/Music app and the underlying MacOS, allowing on-the-fly resolution-switching (and also integer mode rather than floating-point mode, which keeps things bit-perfect). This is the major weakness of Apple's built-in core audio processing: it cannot do on-the-fly resolution switching. ![]() The padding of the bit depth is totally irrelevant - in fact, most "bit perfect" software that claims to leave the original signal totally unaltered will still pad 16-bit (and sometimes 24-bit) content with extra zeroes to match the maximum/default/internal PCM bit-depth of the receiving DAC. So if the Apple MIDI output resolution is set to 24/192, then everything - 16/44.1, 24/48, 24/96, 24/88.2 - will be upsampled to 192kHz, and any 16-bit source will have 8 bits' worth of zeros padded onto each PCM word to convert it to 24 bit. The author wrote this software because he was annoyed that some other companies were charing hundreds and in some cases thousands of dollars for this same functionality.Not sure if you meant to type 24/192 or 24/96, but either way the Apple OS is going to convert everything to that resolution. Better upsampling and digital volume control (although you will always be messing with the bits doing that). Playback of DSD audio files on a DSD-capable DAC.Ĥ. I'm not so convinced, but it doesn't hurt.ģ. Some people believe pre-loading part or all of the track into the memory buffer improves playback. If all you have are mp3 or AAC compressed audio, you aren't going to be able to hear any difference.Ģ. Those who will really benefit from this will generally have a collection including lossless higher-resolution files. If you are using Airplay exclusively, this isn't for you, since everything gets resampled to 44.1 kHz anyway (and if you use Apple TV, gets resampled a second time to 48 kHz). This takes care of the problem automatically. You have to repeat the process each time you play a track with a different sampling frequency, or else your music will get re-sampled. Everything else will get resampled, unless you quit iTunes, change Audio MIDI setup to the new sample frequency manually, and then restart iTunes. If your iTunes library contains tracks that have various sampling frequencies (normal CDs and most iTunes store tracks are 44.1 kHz sampled, "higher resolution" can be 48 kHz, 88.2 kHz, 96 kHz or even higher), iTunes will only be able to play one of these bit-perfectly, depending on the settings in Audio MIDI setup. What does this give you that iTunes does not?ġ. It gives you almost all of the advantages of iTunes (since it runs as a parasite on the iTunes interface), but enables you to avoid some of the limitations inherent to iTunes. Other than that, it is not audiophile, so stop wasting your money on something that cannot be. In other words, forget audiophile, unless you are young, still have good hearing, and have a lot of expendable cash lying around for top equipment starting with output devices and following back to the source. ![]() mediocre headphones or speakers on the end of high end amps and players will not reproduce audiophile quality sound. If you really want audiophile and can hear it, that is where your money should go first. If you don't have that, nothing else matters as that is what your ears actually hear. Finally you have to own speakers or headphones that are capable of audiophile playback ranges with minimal distortion. Any other claims for recording or equipment is marketing hype. If you are over 50 forget audiophile due to hearing age degradation-i.e you can't hear it anyway. lossless audio format from the source., which is not anything on iTunes or MP3. Anything else is compressed and sampled, unless it is stated to be audiophile quality on the source-i.e. ![]() Is this a joke? For Audiofile level recordings you need analog standard (not cassette) tape or vinyl.
