Time-compression artifacts

[Sonny Keyes]

Am I dreaming, or has the time-compression in PT 9 taken a quality hit compared with earlier versions? I used to do overall compressions to bring an announcer read in from 31 to 30 seconds on a radio spot and I couldn't hear problems EVER, and now I can shave 10 frames off a slightly overlength announcer and I hear big clicky artifacts. Maybe it's just a coincidence of voice types or something, but I've noticed it three times in the last couple of weeks. Anyone else?

Hi,

You probably know this! but you can assign any pitch shift plugin in prefs to be used in the TCE tool. I have assigned Waves time shifter, i find it better.

Just the opposite for me! I've used TCE tool with much better results on dry vox. Easily squeeze almost 10% without issue.

For HEAVY time compression/pitch change I use an external app., Prosoniq's TimeFactory 2 http://www.prosoniq.com/editing-products/timefactory-2/

I would recommend Serato Pitch n Time Pro.

X-Form for me, (as long as you're charging by the hour!)

X-form +1

But... when changing tempo on drumloops I use Time Shift and Varispeed to just pitch it up or down without any stretch algorithm involved. Best quality that way but when "stretching" longer files, lets say a whole 3 minutes drumbounce I get several nasty digital spikes in the processed files, it is not an overload thing, can be a spike on a place which before was dead silence...
If I undo and apply the settings again, the spikes will occur on the same places...
Am I alone with this?

D'oh! OK I feel like an idiot for not checking this, but I assumed when I installed PT9 that it would default to the same default compression tool it used to. Instead, it's set to something called "Time Shift" which is why compression all sucked. I changed it back to Digidesign TC/E and everything's fine now. Thanks so much Chris!
