Basic Examples  (1)Summary of the most common use cases

By default, the audio codec used to generate a file is automatically chosen:

In[13]:=13
✖
https://wolfram.com/xid/0d6g1v14eq-quwi7s
In[14]:=14
✖
https://wolfram.com/xid/0d6g1v14eq-6umzn1
Out[14]=14
In[15]:=15
✖
https://wolfram.com/xid/0d6g1v14eq-0of3xj
Out[15]=15

Check for available audio codecs supported for a format:

In[19]:=19

Scope  (2)Survey of the scope of standard use cases

Specify an audio encoding for video generation:
