Hi folks yet another bizarre piece of code that is Apple OSX 10.12.x to at least 10.14.1 specific.
It requires only a default OSX install, and the internal microphone along with an external headphone assembly.

IEEE80211_STA(9) Advanced driver interface STRUCT IEEE80211_STA(9)
NAME
struct_ieee80211_sta - station table entry
SYNOPSIS
struct ieee80211_sta {
u32 supp_rates[IEEE80211_NUM_BANDS];
u8 addr[ETH_ALEN];
u16 aid;
struct ieee80211_sta_ht_cap ht_cap;

enum ieee80211_sta_rx_bandwidth bandwidth;
enum ieee80211_smps_mode smps_mode;

};
MEMBERS
supp_rates[IEEE80211_NUM_BANDS]
Bitmap of supported rates (per band)
addr[ETH_ALEN]
MAC address
aid
AID we assigned to the station if we're an AP
ht_cap
HT capabilities of this STA; restricted to our own capabilities
vht_cap
VHT capabilities of this STA; restricted to our own capabilities
wme
indicates whether the STA supports WME. Only valid during AP-mode.
uapsd_queues
bitmap of queues configured for uapsd. Only valid if wme is supported.
max_sp
max Service Period. Only valid if wme is supported.
rx_nss
in HT/VHT, the maximum number of spatial streams the station can receive at the moment, changed by operating mode notifications and
capabilities. The value is only valid after the station moves to associated state.
bandwidth
current bandwidth the station can receive with
smps_mode
current SMPS mode (off, static or dynamic)
drv_priv[0]
data area for driver use, will always be aligned to sizeof(void *), size is determined in hw information.
DESCRIPTION
A station table entry represents a station we are possibly communicating with. Since stations are RCU-managed in mac80211, any
ieee80211_sta pointer you get access to must either be protected by rcu_read_lock explicitly or implicitly, or you must take good care to
not use such a pointer after a call to your sta_remove callback that removed it.
