ResMed S9s, Philips Respironics System One CPAP and DeVilbiss IntelliPAP machines record snoring data. Fisher & Paykel Icons do not record snoring data.

CPAP machines do not have microphones attached to them. So your CPAP is not listening to the sound of your snoring. So how does it actually detect snoring? It analyzes the Flow Rate data.

Notice, too, that inspiratory snoring (snoring only on inhalations) has a different wave flow than expiratory snoring (snoring only on exhalations). It's also possible to snore on both the inhalations and the exhalations; in that case the oscillations appear on both the inhalation and exhalation parts of the flow rate curve.
