The audiobook editors at Audible used SoundForge. I started out on SoundForge, but I led a real charge to get the department to switch to Wavelab. I was able to get Audible to buy me a license for Wavelab and I never really got anyone else to switch, but it made me super efficient. At that point though I was heading into a more dev role at the company so I was already drifting away from audiobook editing at that point.
