No, but if you check gnuradio-core/src/lib/io/gr_wavfile_source.i, you'll see that the following methods get exported via SWIG: unsigned int sample_rate(); int bits_per_sample(); int channels(); which return exactly what you'd expect (I hope :). Note this is bits - and not bytes - per sample you get. Cheers, mb -- Dipl.-Ing.
