There is a запись_голоса.ogg , you need to programmatically impose any effects so that the output will produce a processed file.
Are there any ready-made libraries or third-party programs with which you can impose ready-made effects via the console or in some other way? For example, helium effect, rough voice or something else.
If there are no ready-made libraries / programs for this, with ready-made templates, then which way to google to deal specifically with this and process the file yourself as needed? In such a case, Java / C ++ methods are of interest. Thanks in advance.

  • beadsproject.net is the first sound processor to find. In general, the easiest way to "open" the finished program for processing votes, even if it is an Android application, get the processing code from there and copy it yourself. - Rostislav Dugin
  • @RostislavDugin I know how this code looks like, and I don’t really want to look at it :) And it’s somehow wrong. Is there really no normal program that can be programname -input file.ogg -effect helium -output file_new.ogg via the console, for example programname -input file.ogg -effect helium -output file_new.ogg ? - Peter Samokhin
  • If you find it, it will be! And the other is more difficult. This is the easiest way. Take the code, refactor and adjust for themselves. If it does, you can ask for an application with good code and documentation (if it happens ...). - Rostislav Dugin
  • I once had fun with SunVox in this direction. - D-side

There is one fairly convenient, simple, cross-platform project with open source and written in two languages ​​for convenience: Sonic .

An example of code can be seen in my answer here , and in fact, I answer my question and attach an example of a working version with a rather broad functionality.
