 The resulting representation $z$ has a dimension of $(d, h, w)$ for a single audio file, where $d$, $h$, and $w$ denote a latent dimension size, latent frequency dim, and latent temporal dim, respectively. 
 [2] indicates that both frequency and temporal dimensional semantics are preserved in $z$.
