I have used this example as a problem to my students to work on decimation
The source file was an interpolated version of a song at 400K
saved with a file sink, and I have tell them that the source was
sampled at 400K, the audio card should work at 16K..... so the
obvious thing yo do was downsample x25 ..... but as I did not say
this last part and the obvious was not obvious for some of them
they did something like this
Apart from the unnecessary throttle, I don't think the audio card of the PC can work at 400Ksps so I haven't tried it, but when they did it the music sounded well in the computer, the question is why?
