My tool for that is an Audacity plug-in called Chris's dynamic Compressor.


An excellent demo of this plug-in is available at


It is accessible.

  Hello Steve
  I've just used audacity for afiew month, I tried your text-envelope plugins, 
and hear is a little suggestion
  1. I'd like to adjust volume of the selected part like adjust using gane with 
focus track. Let me make my suggestion simple:
  when I focus at the track wich I want to adjust gane, Each time I prress 
alt+shift+up arrow, the volume increase, but not much more, then I can press 
that hotkey until I think it's ok. So you might write this like increase / 
decrease current volume by 1db or 1%.
  2. With current feature, I think you can add an option for fading volume. 
This like a plugins called manual duck I downloaded from audacity forum.
  Just use this program for a short time, so I don't have more experience. 
Thanks for asking blind users about this plugin.
  Cuong Dang

    Audacity has an "Envelope Tool" for smoothly adjusting the volume
    level over time. Unfortunately this tool is not accessible for blind

    I have written a plug-in that aims to make this feature available to
    VIP's and other non-mouse users.
    The plug-in is called "Text Envelope" and is available from the
    Audacity wiki: I'm not sure if direct links are allowed on this
    mailing list, but if they are, this is it:

    My questions are:

    1) Is this type of feature of interest to anyone?

    2) Has anyone on this mailing list used the text envelope? If so, how
    did you get on with it? Are there any improvements that you would like
    to suggest?

    4) Does anyone use other methods or techniques for adjusting the
    volume level of a track over time?

    4) Is there some other approach to adjusting the level of part of a
    track that you would like implemented? For example, would you like to
    be able to make part of track go quieter and then return to the
    original volume? Would you like a fade effect that allowed fading
    smoothly to a level other than silence?

    If you would like to try the text envelope but need help installing or
    using it, please ask and I can provide detailed instructions.
