Just set mine up today, don't think it matters when you change the setting in Audio Midi Setup. I'm still trying to figure out how to optimize the system for Apple Music (not having an Exclusive Mode). Some sources say to set to 176.4 and called it a day (will play higher rate samples 'native', will upsample 24/44.1 as required to no deleterious effect).

Would be curious to hear from other Apple Music users...

What about recording vinyl records? Do I set Audio Midi Setup to 32 bit Float or 24 bit Integer? Right now it's set to 32 bit Float, everything seems to sound ok

The decision to record vinyl records in a Digital Audio Workstation (DAW) with 24-bit or 32-bit float depends on various factors. In general, higher bit depths offer more dynamic range, theoretically leading to more accurate capture and playback of audio.

Here are some considerations:

Dynamic Range: 32-bit float provides an extremely wide dynamic range compared to 24-bit. This can be beneficial for minimizing distortions and providing more flexibility during post-processing.

Noise and Quantization: In practice, it might be challenging to hear the difference in terms of noise and quantization between 24-bit and 32-bit float recordings, especially with high-quality vinyl recordings.

File Size: 32-bit files are larger than 24-bit files due to containing more information. If storage space is a concern, this could be a factor.

Processing Overhead: Processing 32-bit float data may require slightly more computational power in some DAWs, which could be a consideration for extensive editing.

Practical Application: If you're archiving vinyl records without extensive editing, 24-bit may be sufficient. If you plan on making significant edits, the additional dynamic range of 32-bit float could be advantageous.

It's important to note that most people may not perceive an audible difference between 24-bit and 32-bit float recordings, especially if the original recording isn't highly demanding. Therefore, practical testing and listening for differences before making a decision could be worthwhile.
