I have a mid-2012 MacBook Pro.
For the past two months, I've been having consistent problems with recorded audio that has no distortion, and was recorded at high quality, suddenly having awful distortion when I import it into Audition. It's like a crackly fuzz kind of sound. Or, I'll have multitrack sessions with a podcast episode I've been editing, and what was once sounding like normal clean audio, will then play back distorted.
I also have not been able to record in multitrack view for several months. I cannot arm the track to record (the R button is inoperable), so I can't record unless I'm in an individual waveform view. (See screenshot)
I've had a support team member help delete cached files (or something like that) once before already. She created a new "Audition" folder in my Library, and renamed the previous folder as "oldAudition." That temporarily solved the audio distortion problem, but not the inability to record in multitrack.
Then this weekend, the distortion started happening again. I uninstalled the most recent version of Audition, and redownloaded Adobe Audition version 10. That still didn't solve my problem.
Please create an updated version of Adobe to solve these problems, and please also consider improving your customer support. It's way more difficult than it should be for me to speak to someone who is a native English speaker on the phone and sort these issues out, or at the very least send a detailed email. This forum is a last resort.
I love Audition. I want to keep using it. But I'm about ready to call it quits at this point.

It worked! THANK YOU.
I had a previous mentor tell me to use 16 samples as my default, so I really appreciate you clarifying a better default.
So relieved I can edit as usual now.
A buffer size of 16 samples is exceptionally low and even with a completely modern system with acceleration hardware, is unlikely to get good results with all but the most simple of sessions. If you're not actively recording in sync against other tracks (such as playing guitar against a drum track) then higher buffer sizes are generally best for playback and recording performance. I would recommend using the typical default of 512, but if you still experience distorted playback, increase it incrementally until you reach a setting which doesn't cause dropouts and distortion.

Thanks for getting back to me.
My buffer size is always set to 16, with the sample rate usually set at 44100. I'm still having issues with my audio being distorted when I try to playback in Audition.
Thank you with explaining how to enable the track to record in multitrack view. I hadn't learned that new setup method with the update. Last experience I had was with Audition CC 2017 where it automatically set up the input or something to where I always had the R enabled.
At this point I'm still left with distorted audio. I'm trying to produce and publish podcast episodes, and at this point these problems are pushing back my release date, so any help I could get to have this resolved as soon as possible would be much appreciated.
Sorry to see you're having some problems. Since everything was working well before, my assumption is it may just be some configuration settings that need to be modified. Looking at your screenshot, the reason you can't arm a track for recording is there is no Input device selected (The box with the arrow pointing to the right.) Let's take a look at a few things.
1. Please click the Adobe Audition CC title in the top-left corner of the screen and select Preferences. Click on Audio Hardware and confirm what you have selected for Default Input and Default Output, as well as Latency (or Buffer Size) and Sample Rate.
2. If the Latency/Buffer Size is set too low, you'll likely drop samples during playback or record, which can manifest in distortion like you describe. For recording or editing a podcast, a low latency isn't necessary, so I would suggest setting that value toward the high end. As a test, try setting it to the largest amount, then click OK and try to playback your project. If the distortion is gone, you can try setting it back a level or two at a time until the distortion comes back, then reset it to the lowest value without problems.
3. If you have the correct recording device selected in the Default Input preference, then click on the Track Input box on one of your tracks. In your screenshot, this is the box next to the right-pointing arrow that currently reads "None" Once your microphone is selected, you should be able to arm the track for record, see the levels, and capture a recording.
Let me know how these go and if we need to continue troubleshooting, we can.
