I noticed during my tests, that in Wavelab 10 the rendering is done “Fast” in the Tasks window, where in Wavelab 11 the Tasks windows says “Normal” for status. For my limited private usage of Wavelab this might be somewhat tolerable, but for a professional user/company the render time seems very inefficient…
I tried to add and remove some other plugins into Master Section (bypassed or deactivated) to see if there is any difference in render time, but it didn’t seem to change anything. I cannot compare to the offical plugin, since I don’t have a license and my trial period is expired (seems like I installed this dither before). The LinPro in WL 11 takes very long ~43 seconds to render, and even with the settings it’s still ~25 seconds.MBit+ Dithering in iZotope RX9 is done within ~3.2 seconds. With the settings render time increases to ~8.2 seconds. The iZotope Mbit+ Dither in WL 10 needs ~5 seconds.The Apogee UV22HR in WL 10 renders almost as fast with ~1.7 seconds.The Internal Dither takes incredible ~1.5 seconds to render, both versions of Wavelab.System is Windows 10 (21H2), with AMD Ryzen 9 5900x and 32GB RAM. No other plugins were loaded into the Master Section. I did some quick tests with an hour long file (44100 Hz, 32 Bit Float - dither to 16 Bit) in WL 10.0.70 and WL 11.1.10.
I just upgraded from Wavelab Pro 10.0.70 to Wavelab Pro 11.1.10 and I can confirm, that the LinPro Dither from Wavelab is very slow in comparision with other dithers integrated into Wavelab.
