Abstract: To a special embedding $\Phi $ of circle algebras having the same spectrum, we associate an r-discrete, locally compact groupoid, similar to the Cuntz-Krieger groupoid. Its $\mathbf {C}^*$-algebra, denoted $\mathcal {O}_{\Phi }$, is a continuous version of the Cuntz-Krieger algebras $\mathcal {O}_A$. The algebra $\mathcal {O}_{\Phi }$ is generated by an AT-algebra and a nonunitary isometry. We compute its K-theory under the assumption that the AT-algebra is simple.
