SteadySound is a small, feature-packed utility for adjusting the volume throughout audio files. It's basically an RMS meter, AGC (automatic gain control), and limiter combined, with a whole bunch of options. More documentation is coming soon, but you can see a list of the program options along with short descriptions by running steadysound --help.
Right now there's no build system, but it's very easy to compile. The development version of the following libraries are required:
- libsndfile
- Boost.Program_options
On Ubuntu, install the dependencies like this:
sudo apt install libsndfile1-dev libboost-program-options-dev
Other Linux distributions should have similar packages.
Compile the program:
g++ *.cpp -Wall -lsndfile -lboost_program_options -o steadysound
I use MSYS2 to compile on Windows. It's a great way to set up a MinGW environment, and it includes bash, the pacman package management system, and a whole bunch of ready to use packages. After installing it, you'll need launch the MSYS2 MSYS shell and install the required packages:
pacman -S base-devel mingw-w64-i686-gcc mingw-w64-x86_64-gcc mingw-w64-i686-libsndfile mingw-w64-x86_64-libsndfile mingw-w64-i686-boost mingw-w64-x86_64-boost
Running that command will install everything you need to compile both 32-bit and 64-bit binaries. To build, launch either the MSYS2 MinGW 32-bit or 64-bit shell, depending on which architecture you want to build, and run this command:
g++ *.cpp -Wall -lsndfile -lboost_program_options-mt -o steadysound.exe
Once it's compiled, you will probably have to copy some DLLs from [MSYS2 installation directory]/mingw[32|64]/bin/ to get it to run.
