Overall my impression of CS6 is much more positive than CS5.5. I'm seeing features restored from 3.0 that are great to see back again. I'm also enjoying some of the new functionality. But some key features of AA3.0 are still missing, which I used often.
1. Generate Silence. This is useful in the waveform editor in many cases. It's great we can generate tones, but silence is the blank canvas that is needed.
2. Sample editing by dragging individual samples. Perhaps this exists, but I couldn't figure out how to do it.
3. Generate noise (pink, white). Fundamental in audio. We need this.
4. Spectral Phase Display. Please bring this back from AA3.0. Incredibly useful, and much more powerful than the very rudimentary phase display in CS6. I use this often in AA3.0.
5. Spectral Pan Display. Was not used by me as often as Spectral Phase Display, but still useful to have.
6. Hovering or left-clicking at the top or bottom of a stereo waveform selects or plays only the Left or only the Right channel. This is much easier in realtime to compare left/right channels than using the buttons at the right to deselect channels.
And, new things not related to AA3.0:
1. Ability to use Normalize in effects rack. This is one of the most common effects I would use for working with certain audio files.
2. 64-bit support in Windows 7. CS6 appears to be a 32-bit application. If so, will a 64-bit version be available?
There are new things I'm enjoying about CS6. So overall this is a great effort coming from CS5.5. But AA3.0 remains installed on my PC. Please restore the other features above from AA3.0.
