Installing the latest libsndfile

You need to install the latest libsndfile for using the MP3 output file capability of airspy-fmradion.

MP3 capability

• libsndfile 1.1 and later is MP3-capable when LAME is installed.
• libsndfile 1.0.31, the stock version for Ubuntu 22.04.4 LTS, does not have MP3 handling capability.

For macOS: use Homebrew

brew install libsndfile

Installing the latest libsndfile on Linux

For Ubuntu 22.04.4 LTS

Use the following cmake command in the CMakeBuild/ directory:

cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=ON \
      -DBUILD_SHARED_LIBS=ON \
      -DBUILD_TESTING=ON
