Adobe Audition recording frequency cutoff at 11-12 kHz — Audacity on same setup records full 20 kHzSetup:Sennheiser MKH 416 → Apollo Twin X Gen 2 → Adobe Audition on MacThe problem:Frequency analysis in Audition shows a hard cutoff around 11-12 kHz. Audacity recording through the exact same Apollo Twin shows full frequency response up to 20 kHz. The problem persists in Audition regardless of settings.What we've already tried:Verified sample rate is 48000 Hz in Audition, UA Console, and export settings Switched Apollo input from LINE IN to MIC IN with 48V phantom power enabled Removed all UAD plugins from the channel strip completely Turned off LINE INPUT GAIN in Apollo hardware settings Changed I/O Matrix routing from AUX1 L to MIC/LINE/HIZ 1 Turned off the high pass filter on the Apollo channel Reset Audition preferences using Ctrl+Alt+Shift on launch Manually deleted Audition preference files from Library folder Fully uninstalled and reinstalled Audition including removing preferences Tested with multiple microphones — problem persists in Audition onlyResult: Audacity works perfectly. Audition still cuts off at 11-12 kHz after all of the above. Something in Audition's signal handling is limiting the frequency response that we cannot identify through settings alone.

Adobe Audition recording frequency cutoff at 11-12 kHz — Audacity on same setup records full 20 kHz

Setup:
Sennheiser MKH 416 → Apollo Twin X Gen 2 → Adobe Audition on Mac

The problem:
Frequency analysis in Audition shows a hard cutoff around 11-12 kHz. Audacity recording through the exact same Apollo Twin shows full frequency response up to 20 kHz. The problem persists in Audition regardless of settings.

What we've already tried:

Verified sample rate is 48000 Hz in Audition, UA Console, and export settings
Switched Apollo input from LINE IN to MIC IN with 48V phantom power enabled
Removed all UAD plugins from the channel strip completely
Turned off LINE INPUT GAIN in Apollo hardware settings
Changed I/O Matrix routing from AUX1 L to MIC/LINE/HIZ 1
Turned off the high pass filter on the Apollo channel
Reset Audition preferences using Ctrl+Alt+Shift on launch
Manually deleted Audition preference files from Library folder
Fully uninstalled and reinstalled Audition including removing preferences
Tested with multiple microphones — problem persists in Audition only

Result: Audacity works perfectly. Audition still cuts off at 11-12 kHz after all of the above. Something in Audition's signal handling is limiting the frequency response that we cannot identify through settings alone.

Can we see your Audition Audio Hardware settings?

(Disclaimer - It’s a Mac - I don’t have one...) But whatever it turns out to be, I’m afraid it won’t be Audition - well, not directly anyway. Audition is notorious for recording exactly whatever it’s sent from your sound device driver and the OS - so Rag and Bone is on the right lines to look at the system, I think. One thing that’s been reported before though relates to monitoring settings - some Bluetooth devices can cause bandwidth issues, apparently. This is probably related to the aggregation settings, and it may be that any devices included in the settings that have a low bandwidth (like ear-buds) may force the entire system to work at whatever rate that is, but get finally resampled to 48k - but with the damage caused on the way in.

But as I said, I don’t have a Mac so this is speculation. Incidentally, PCs do have an aggregation device available - this is what ASIO4ALL is - and that, if fiddled with, this can cause all sorts of issues! So, I don’t know if this is going to be of any help, but it should give some clues as to where perhaps to look. I think I’d also be a bit curious as to why Rag and Bone is seeing different options from yours - you might want to check for a driver update.
