Ripping CDs to ALAC with macOS Catalina

Recommended Posts

Hi,

do some of the beta testers have experiences with ripping cds to ALAC under Catalina?

Is the ripping engine of Catalina similar to iTunes or do exist some differences?

What about the sound quality?

Thanks

 

Matt

I can't imagine that it would be any different, but I haven't yet tried. (It's still based on the same framework, and, while there may have been updates to that framework, I can't imagine they would affect ripping other than perhaps making it faster or more efficient.) 

 

How would the "sound quality" be different if it's lossless?

You can use the built-in unix command afhash to assess whether the SHA-1 hash is the same on a track ripped in the new OS vs. an older one.

 

If the SHA-1 hashes (checksums) are identical, then the audio is bit-identical, so most folks would take that as proof that both sound the same.

But all it takes is a tiny bit of difference in header information for the SHA-1 to be  different.

No, it is an internal checksum, just like the one embedded in a FLAC file.  Try it with two copies of the same file, after chaning the metadata in one of them.

I don't know why someone would recommend EAC as it is a windows program. It might run under WINE but there is an excellent free Mac ripper in XLD that uses the Accurate Rip data base. dbPoweramp has a Mac version but it is payware though worth the price for the metadata information it provides. 

 

It's Windows users who don't know anything about the Mac. As often, people chime in in forums about subjects they know little about.

Or sometimes they wrongly assume the other person is incorrect.

 

The great thing about open forums is that we can all learn a bit from one another.

I will follow up on that cue...

 

why does my iMac have so much trouble recognizing USB devices and SD cards?  Works intermittently; fails often.


"The overwhelming majority [of audiophiles] have very little knowledge, if any, about the most basic principles and operating characteristics of audio equipment. They often base their purchasing decisions on hearsay, and the preaching of media sages. Unfortunately, because of commercial considerations, much information is rooted in increasing revenue, not in assisting the audiophile. It seems as if the only requirements for becoming an "authority" in the world of audio is a keyboard."
