I use Magix Movie Edit Pro 17 and i've had no complaints with it and done some pretty descent stuff:

but on the first one, I had to do some audio correcting and there was a crimp in the armor. I've used a variety of audio editors before ranging from Adobe Premiere Soundbooth, WaveLab, Audacity, Goldwave and these are pretty straight forward and do avery effective job. However, in Edit Pro 17 the audio editor went to Magix Music Editor 3 and not to go base in being descriptive but this program was simply awful. The editing capabilities were clumsy and difficult to do the simplest of tasks. I needed to clean up two small spots and it took me longer to fiure out how to get rid of them versus with the other audio editors. The only difference is that this kept me in the Edit Pro program versus going out of it and cleaning up the audio and reconfiguring the video again.
Is there somewhere in your base where there is adescent audio editor that's intergrated with Edit Pro 17 that's on the same function as Audacity or Goldwave equivalent?
