Audioconvert converts raw audio buffers between various possible formats. It supports integer to float conversion, width/depth conversion, signedness and endianness conversion and channel transformations (ie. upmixing and downmixing), as well as dithering and noise-shaping.
| 1 | gst-launch-1.0 -v -m audiotestsrc ! audioconvert ! audio/x-raw,format=S8,channels=2 ! level ! fakesink silent=TRUE | 
This pipeline converts audio to 8-bit. The level element shows that the output levels still match the one for a sine wave.
| 1 | gst-launch-1.0 -v -m uridecodebin uri=file:///path/to/audio.flac ! audioconvert ! vorbisenc ! oggmux ! filesink location=audio.ogg | 
The vorbis encoder takes float audio data instead of the integer data output by most other audio elements. This pipeline decodes a FLAC audio file (or any other audio file for which decoders are installed) and re-encodes it into an Ogg/Vorbis audio file.
