Since all transfers are made digitally, there is no loss in sound quality.

A person could use two or more software audio generators, synthesizers or sequencers to produce audio streams and send them to a VAC output cable and record the mixed stream from the VAC input cable using any type of recording software.

Because VAC routes audio streams in almost real time, it is able to be utilized in various manners.

[4] Practically, the input port records the audio signal (for example from a music player) and sends it to the destination program (such as a sound processor or analyzer) using the output port.

[5] A user could also manipulate VAC into recording conversations through Voice Over IP (VoIP)[6] or Internet telephony applications such as Skype[7][8] (for example, with SAM Broadcaster[9]), produce live audio podcasts,[10] redirect audio channels to multiple monitors,[11] or even decode weather faxes.
