Re: Re: gr.wavfile_source

Martin (or anyone else), I have an additional question about

after opening the file (with self.src = gr.wavfile_source
(options.filename, True)), is it possible to get some of the
parameters and use them in the code?

I’m particularly interested in d_sample_rate(1), d_nchans(1),

I tried self.src.d_nchans, but it tells me: AttributeError:
‘gr_wavfile_source_sptr’ object has no attribute ‘d_nchans’

Thank you for your help

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.
