Audio version of Streetwise Spanish Dictionary/Thesaurus

[pon00050]

This is the book that I bought recently:
Streetwise Spanish Dictionary/Thesaurus

In it, it states "the book is also available with an accompanying recording
that includes the conversations performed by native speakers from each of
the countries represented, oral exercises not found in the book, and
explanations of the various accents and dialect".
I REALLY want to buy the recording.
The problem is that I cannot locate the website link that sells it.
I have searched the publisher's website but it doesn't offer
the choice to buy the recording only.
Please direct me to the link if posible.
Muchas gracias
