It was recorded during a video chat by a man who lives near the scene of the shooting in Ferguson, Missouri.
This audio - obtained exclusively by CNN, but not independently verified -- allegedly the gunshots fired during the shooting death of 18 year old Michael Brown.
A lawyer for a Ferguson resident says her client recorded this audio while video-chatting with a friend, when the unarmed teen was shot by Ferguson police. His lawyer says he was questioned by the FBI about the audio.
Listen again as you hear a series of gunshots fired -- then a brief pause -- followed by another round of shots.
"It's not just the number of gunshots but how they were fired that has a huge relevance on how this case might turn out," explains Lopa Blumenthal, the attorney for the man who recorded the sounds.
CNN cannot independently verify the authenticity of the tape and has reached out to the FBI for confirmation.
Facing the possibility of charges in the shooting...28 year old officer Darren Wilson. The grand jury not expected to return a decision until mid October.
Heavy police presence, protests and violence on Ferguson streets thrust the small community into the national spotlight.
But, inside the Friendly Temple Missionary baptist church Monday -- a somber service to lay Michael Brown to rest.
"Yes we called him the gentle giant, we called him Big Mike, we called him Mike Mike. He said one day the whole world will know my name," reflected Rev. Charles Ewing, Michael Brown's uncle.
Standing before her son's photos and his casket, his mother Lesley McSpadden grieving -- wiping away tears.
Among the thousands gathered inside were friends and family -- and many who came to pay their respects to the slain teen -- having never known Brown personally.
That included well known public figures like Rev. Jessie Jackson and Spike Lee, who tweeted during the service: "Our brother Mike Brown's St. Louis Cardinals hat lays upon his casket here at the home going…"
On this day protesters stayed silent but mourners were reminded of the need for change.
"Michael Brown's blood is crying from the ground, crying for vengeance, crying for justice," Ewing told mourners.
