How do I measure the sample rate of an imported file in Mathematica?
I imported the WAV file:
solo = Import["solo.wav"] When I wrote:
SampleRate[solo] I received: 
But I just need a number like 28.000 to be returned.

0 solo = Import[ "ExampleData/rule30.wav" ] 
Cases[solo, (SampledSoundFunction | SampledSoundList)[__, r_] :> r, Infinity][[1]] 44100

One can also use Import[] to directly query the *.wav file's sample rate, like so:
Import["ExampleData/rule30.wav", "SampleRate"] 44100 answered May 10, 2016 at 0:01

1 The sample rate is the second element in solo. The first element (i.e., solo[[1, 1]]) is the waveform data.
solo = Import["ExampleData/rule30.wav"]; solo[[1, 2]] 44100

For Mathematica 11:
AudioSampleRate[myAudio]
