Multi-track audio editing using key frames (FEATURE REQUEST)

[Don Spark]

In terms of audio, I cannot function without
Multi-track audio editing using key frames(control points)
(to adjust volume levels)
At the end of the day, that is 90% of what I am doing with audio in post.
8% of what I do involves basic EQ. 2% is sweetening and getting rid of audio artifacts hiss.

As an semi-pro industrial producer and political guerilla videographer(taught video production for 3 years full time) paying the bills with video for law firms, it's only about the practical and getting down to brass tacks for me...and speed. How fast can I turn the video around? I need fast basic video, text graphics and audio editing functionality which is rock solid that renders immediately.

There are finer points to the way Multi-track key frame audio editing works. The more flexible the better I guess. Also, there seem to be numerous video editor conditions that can cause the audio to become un-locked or un-synced from the video. That is the worst audio wrench in the machinery of turing out video fast.

This is not strictly analogous but helps to put into perspective what I need and expect to get work done. I had done a fair amount of amateur/semi-pro linear(tape based) video editing when I got into digital video when a relatively inexpensive digital editor as part of a firewire system first possible in 1998. I did several paid jobs on this system. I could not have done it without "Multi-track audio editing using key frames". This was what my system looked like; perhaps the first really practical financially feasable for amateurs and semi-professional.
