Issue importing python soundfile library - OSError: library not found: 'sndfile'

Question

I am hosting a python flask service that does audio computations using soundfile library. It runs fine on my local but when i host it on redhat, i see the below issue. Any suggestions -

 from soundfile import read
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/soundfile.py", line 265, in <module>
    _snd = _ffi.dlopen('sndfile')
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 139, in dlopen
    lib, function_cache = _make_ffi_library(self, name, flags)
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 769, in _make_ffi_library
    backendlib = _load_backend_lib(backend, libname, flags)
  File "/apollo/env/AQTAudioPoProService/lib/python3.4/site-packages/cffi/api.py", line 757, in _load_backend_lib
    raise OSError("library not found: %r" % (name,))
OSError: library not found: 'sndfile'

Tried installing libsndfile

No package libsndfile available.

The soundfile Python module depends on the libsndfile native library. You'll need to install it on your operating system:

$ yum install libsndfile
