## Abstract

An edge device includes a microphone and is configured to detect a static position of the edge device for a first time period and to record audio received by the microphone while the static position remains constant. The device determines whether a target sound is within the audio received by the microphone by analyzing audio and sends an alert when the target sound is determined to be within the audio. The target sound may include a firearm discharge. Additionally, or alternatively, the edge device analyzes the audio for types of decibel levels and echoes inside the audio that track to the firearm discharge. The alert may comprise a package of information that includes a location.

## Claims

### Claim 1

An edge device comprising a microphone, the edge device being configured to:
detect a static position of the edge device for a first time period;
record audio received by the microphone while the static position remains constant;
determine whether a target sound is within the audio received by the microphone by analyzing audio; and
send an alert when the target sound is determined to be within the audio.

### Claim 2 (depends on 1)

The edge device of claim 1, wherein the target sound comprises a firearm discharge.

### Claim 3 (depends on 2)

The edge device of claim 2, wherein the edge device is configured to analyze the audio for types of decibel levels and echoes inside the audio that track to the firearm discharge.

### Claim 4 (depends on 1)

The edge device of claim 1, wherein the alert comprises a package of information including a location.

### Claim 5 (depends on 1)

The edge device of claim 1, wherein the alert is configured to cause an immediate order of emergency service or dispatch of additional resources.

### Claim 6

A method for processing a sound, comprising:
detecting a static position of an electronic network device for a first time period;
recording audio by the electronic network device while the static position remains constant;
analyzing the recorded audio by the electronic network device to determine whether a target sound is within the recorded audio; and
causing the electronic network device to send an alert when the target sound is determined to be within the recorded audio.

### Claim 7 (depends on 6)

The method of claim 6, wherein the electronic network device is an edge device.

### Claim 8 (depends on 6)

The method of claim 6, further comprising the electronic network device analyzing the recorded audio for types of decibel levels and echoes inside the audio that track to a firearm discharge.

### Claim 9 (depends on 6)

The method of claim 6, further comprising the electronic network device sending an alert that includes a package of information including a location.

### Claim 10 (depends on 6)

The method of claim 6, further comprising automatically triggering an immediate order of emergency service or dispatch of additional resources in response to the alert sent by the electronic network device.

### Claim 11

An emergency vehicle comprising an electronic network device including a microphone, the electronic network device being configured to:
detect a static position of the emergency vehicle for a first time period;
record audio received by the microphone while the static position of the emergency vehicle remains constant;
determine whether a target sound is within the audio received by the microphone by analyzing the recorded audio; and
send an alert when the target sound is determined to be within the audio.
