Error Loading SoX

  • 772

I use a really useful tool called r128gain which performs loudness normalisation on audio files. Under 17.10, however, I get the following error however...

Failed opening "/home/Downloads/r128gain-1.0.11-linux64-gtk3/r128gain-tools/libsox.so.2".
Error loading SoX.

Can anybody shed any light on this for me, I would love to get it working again? Thank you!

  1. Best Answer

    It seems the tool is missing the soxinstallation

    sudo apt-get install sox

    should fix it

    Edit: Installing alone did not fix it, you have to tell r128gain where to look for the sox library

    mv /home/username/r128gain-1.0.11-linux64-gtk3/r128gain-tools/libsox.so.2 /home/username/r128gain-1.0.11-linux64-gtk3/r128gain-tools/libsox.so.2_backup

ln -s /usr/lib/x86_64-linux-gnu/libsox.so.2 /home/username/r128gain-1.0.11-linux64-gtk3/r128gain-tools/libsox.so.2

    Then it works

    ./r128gain  /usr/share/sounds/alsa/Noise.wavSoX sucessfully loaded.
FFmpeg sucessfully loaded.

      peak: -17.9 TPFS, range: 0.0 LU

  2. SoX executable in r128gain-1.0.11-linux64-gtk3/r128gain-tools depends on libpng12 (not exist in modern Ubuntu), so we need to install it manually:

    wget http://ftp.us.debian.org/debian/pool/main/libp/libpng/libpng12-0_1.2.49-1+deb7u2_amd64.deb
sudo dpkg -i libpng12-0_1.2.49-1+deb7u2_amd64.deb

    After this it works:

    artful@artful:~/Downloads/r128gain-1.0.11-linux64-gtk3$ ./r128gain  /usr/share/sounds/alsa/Noise.wav SoX sucessfully loaded.
FFmpeg sucessfully loaded.

      peak: -17.9 TPFS, range: 0.0 LU
