Compression Processing glitch? -Sound Forge - PC - MAGIX Community Forums Archive

Subject:Compression Processing glitch? Posted by: Toohipfortheroom Date:3/20/2002 10:47:16 AM Okay, here goes..... I often use the hard limiting setting on the Graphic Dynamics Compressor.....smooth out the peaks, etc. in my tracks during mixing. Worked fine on 4.5, but the exact same settings yield different results on 5.0! Specifically......if I take a track that seems based around a 6.0 level, but with spikes above it, I set the compressor to the "limit levels to 6db" preset. On 4.5, the result is a wave that looks like it just got a flat-top haircut...perffectly shaved across the 6 db line. On 5.0, however, the guy giving the haircut must need glasses...it shaves about 90-95% of the spikes to 6db, and misses a few! I can live with it in some cases, but it really screws up your normalization if you have one or two spikes in a three-minute track.....what's goin' on? I have A-B'd 4.5 and 5.0 using the exact same settings on the exact same wave file - shouldnt the result be the same? Tony

In fact, i run 5.0 both at home and at church and see different results between the two installations (yes, both running 5.0f with identical compression settings on the same source files). What i've done is set the attack to the minimum value, then after compressing zoom all the way out and look for the few leftover peaks and use Fade, Graphic to manually reduce them. It's somewhat of an annoying pain, but it does get the job done.
