Yes, these are correct.

This specifies the sample parameters (sample rate, channels, bits,
etc). audioio.h contains the definition for this.

Yes, this specifies the buffersize in samples. Same as ecasound's
"-b" option.

As I mentioned in my earlier post, another way to use libecasound.so
is through ECA_CONTROLLER class. You should see ecatools source files
for more info. Also

Otherwise eca-chainsetup.cpp should prove helpful.
