CD to DAT Conversion 

Use ArrayResample to convert between different sample rates. Converting between CD and DAT is one of the most common conversions.

Import an audio signal.

In[1]:=

X snd = ExampleData[{"Sound", "Cello"}]

Out[1]=

Convert sampling rate from 44.1 kHz compact disc (CD) to 48 kHz digital audio tape (DAT).

In[2]:=

X ListPlay[ArrayResample[snd[[1, 1, 1]], Scaled[48/44.1]], PlayRange -> {-1, 1}, SampleRate -> 48000]

Out[2]=
