[Audacity-devel] q/d hook for 'chain of effects'

[Lynn A. <l_d...@ad...>]

This may or may not have merit, but there might be a relatively
straightforward way to implement a pseudo scripting capability.

My use of Audacity as a base for the derived "CleanSpeech" app centers
around invoking a "chain of effects" that is quite fixed:
- mp3 to wav (if applicable)
- stereo to mono (if applicable)
- normalize
- click-removal
etc.

This can be for the file that is currently loaded, or an entire batch
of files.

Perhaps my usage isn't at all like others, but I would think some
experienced users would like to have the capability of clicking on a
"One Button Trigger" that had the result of firing off an arbitrarily
defined series of effects that suited their purpose.

The "Audacity CleanSpeech" app has a menu item and button for
"CleanSpeech Chain" that triggers its "chain of effects". Perhaps the
real Audacity app could consider having something similar (but named
differently), and read a very simple script from a defined file to do
something similar. It could either use presets for the effect
parameters if they were 'persistent', or have the effect presets in
the script.

Just as an example, CleanChain might have something like:

# Chain.aud
Mp3ToWav
StereoToMono
Normalize
ClickRemoval
NoiseRemoval
SpikeCleaner
Leveler
Normalize
ExportMp3

Someone else might want to have the following happen:
# Chain.aud
Normalize
Trim
Repeat

Just a thought. Feedback appreciated. A side effect is that the
approach leads into being able to process an entire batch of files
with the same "chain of effects".
