How do you convert 192Khz audio to 96Khz?

[rbpeirce]

I'm guessing there ie an obvious solution but Google can't find it.

I have a 192Khz download I can't play. I need to convert it to 96Khz.

What did you download? And there's likely no reason that you can't play it at the higher frequency. Always make posts with excruciating detail, we aren't watching your shoulder to know what you are talking/looking about/at.

I downloaded a 192Khz audio album. I read Macs couldn't handle anything over 96Khz. However, you are correct. I tried to play it on a mini running Mojave and it played. I have no idea why. It is only 9 tracks so it wouldn't be much of a loss if I couldn't play it. Still .. .

 

[Raz0rEdge]

Downloaded what? MP3? WAV? FLAC? AIC? OGG? As long as the audio file is supported by the player, it will play regardless of what the frequency is. High rate MP3's are 320 Khz and provide the best quality of playback.

You started with that it needed conversion, then said it wouldn't play, then that it does. So, what is it you now need/want? We cannot read your mind.

I'm saying you've answered my question. Since I understood that anything over 96K wouldn't play I never tried it. This is a 192Khz m4a file and it does play, although I have no idea why. Maybe Macs automatically downsample or something.

 

[MacInWin]

Probably not, it just plays. No need to get all complex. Don't know where you got the idea that it was unplayable, but clearly it is, so that source is, at best, outdated or unreliable.

It's my understanding that the KHz (frequency) is irrelevant as regards the ability to play the music; it's the audio format (Codec) which is critical - does the Mac recognise it?

In your case, it appears that it does.

Boy was I wrong. It turns out the DAC connected to my mini plays 192Khz so the mini just sends it out and it works.

Now the question is how do I get Music on my M1 MBP to recognize my iTunes library on an attached HD? I need to do that to see what happens if I try to play a 192Khz track without the DAC.

In iTunes I just opened the program while holding down the OPT key and I could select the attached library. That doesn't seem to work with Music. What's the procedure?

This library is not "organized" in preferences.

What's the procedure?

Use multiple libraries in Music on Mac

On your Mac, use multiple libraries and switch between them.

OK, I'm stuck. Every time I try to select the iTunes itl file and load it into Music it crashes. I even tried shutting down and rebooting. Consequently, I can't connect my library to my MBP which means I can't test a 192Khz track to see if it will play. I'm stymied. I think we ought to end this thread until I get everything working.

 

[MacInWin]

In Music, Settings, there is a pane for "Files." You can select the location for your music library there. What happens if you set it to the old iTunes library location?

EDIT: And just out of curiosity, what happens if you just double-click on this audio file? If it is of a format that Music recognizes, it should just start to play. If the format isn't something Music recognizes, that is a separate issue that would need work. You have never told us what kind of audio file it is.

You are leaving a lot of important information out, I think.

Let me add this. There is a known issue in Monterey of AMPLibraryAgent crashing while trying to load an iTunes .itl file into Music. The way things are I cannot attach my iTunes library to my Monterey computer and test whether it can play a 192Khz audio file or not. Until then I am stuck with iTunes on my Mojave mini, which thank goodness, works fine.

Not true. Copy the file to the Mini. Double click. If it's a format (you STILL haven't given us a clue what that format is) that Music can read, it will play.

and

WHAT IS THE FILE FORMAT?

And yet,

it worked perfectly for me, on my MBP, with Music, in Ventura. ???

 

[rbpeirce]

I considered upgrading to Ventura but x.1 appears to be a bit buggy. As far as I have been able to determine the problem only exists on Monterey, naturally! The two previous releases and the next seem to be ok.

I don't know the file format. It is an .itl file. Re-reading your prior note I think you are suggesting just copying the m4a file from the HD on the mini to my MBP. That's a good idea.

In all sincerity, I've not come across any Music problems at all. Maybe I'm one of the luck ones.

Not quite sure that is so; but like you I have deferred my upgrade to Ventura till it gets to .2

This has been my practice with all upgrades. Basically, I'm a coward I suppose

Thanks so much for the tip. First of all it turns out it is an aif file not an m4a. I have no idea what that means. Second, get info says it is a 192 kHz Sample Rate but it plays! I have no idea why. Everything I've read says the DAC only works up to 96 kHz. Did Apple lie?

This is specifically a problem with something called AMPLibraryAgent that Music loads to convert an itl file. I only found it by specifically Googling for that name. Supposedly, and I have no way to confirm this, it works on previous OS releases and apparently on the next one but not on Monterey. I will likely move to Ventura on the next update.

AIFF, What is AIFF, AIFF File Extension

Apple format for audio files. No surprise it played, it's Apple's format scheme.

You need to change what you read. You seem to have read a lot of misinformation on this topic.
