Hi, I don't know volk_32fc_convert_16 ic. Dunno if it converts between big and little indians:( When converting a float to int, you always have to ceil or floor the float. Ceil sounds as good as any. You can easily change that to floor if you run into problems. Since clibs le32to* take ints as arguments, I would first convert float32 to int32 from gnuradio save to file, and then worry about the indians when importing to uhd...
