The user-generated audio is second and alternate audio supplanting or replacing the original audio associated with the video. Using a mobile app, each user receiving the second alternate audio can play, pause, and/or replay the livestreamed second alternate audio. ## Claims ### Claim 1 A system comprising: a display associated with a first user for displaying a first video to the first user without playing a first audio corresponding to the first video; and a user device associated with the first user which receives a second audio different from the first audio, the user device including: a speaker for outputting the second audio to the first user without playing the first audio to the first user; wherein the second audio is generated by an operator different from the first user. ### Claim 2 (canceled) ### Claim 3 (canceled) ### Claim 4 (depends on 1) The system of claim 1, wherein the second audio is livestreamed to the user device. ### Claim 5 (canceled) ### Claim 6 (depends on 1) The system of claim 1, wherein the first user includes a plurality of first users; and wherein the second audio is broadcast to the plurality of first users. ### Claim 7 (depends on 1) The system of claim 1, further comprising: a network for livestreaming the second audio to the user device. ### Claim 8 (depends on 1) The system of claim 1, wherein the user device includes a controller which allows the first user to control the playing of the video and the second audio. ### Claim 9 (depends on 8) The system of claim 8, wherein the user device includes a mobile app which, in conjunction with the controller, allows the first user to control the playing of the video and the second audio. ### Claim 10 (depends on 1) The system of claim 1, further comprising: a transmitter for transmitting the second audio to the user device. ### Claim 11 (depends on 10) The system of claim 10, wherein the transmitter livestreams the second audio to the user device. ### Claim 12 A system comprising: a display associated with a first user for displaying a first video to the first user without playing a first audio corresponding to the first video; a user device associated with the first user which receives a second audio different from the first audio, the user device including: a speaker for outputting the second audio to the first user while the first video is being displayed and without playing the first audio to the first user; and a transmitter for transmitting the second audio to the user device; wherein the second audio is generated by an operator different from the first user. ### Claim 13 (canceled) ### Claim 14 (canceled) ### Claim 15 (depends on 12) The system of claim 12, wherein the second audio is livestreamed to the user device. ### Claim 16 (canceled) ### Claim 17 (depends on 12) The system of claim 12, further comprising: a network for livestreaming the second audio to the user device. ### Claim 18 (depends on 12) The system of claim 12, wherein the user device includes a controller which allows the first user to control the playing of the video and the second audio. ### Claim 19 (depends on 18) The system of claim 18, wherein the user device includes a mobile app which, in conjunction with the controller, allows the first user to control the playing of the video and the second audio. ### Claim 20 A method comprising: an operator receiving a first video along with a corresponding first audio; the operator generating a second audio different from the first audio and transmitting the second audio and first video to a user device of a first user without transmitting the first audio; the first user receiving the second audio and the first video; and the first user broadcasting the second audio and the first video to a plurality of second users. ### Claim 21 (depends on 1) The system of claim 1, wherein the second audio is further modified by the first user to generate a third audio, where in the third audio is broadcast to a plurality of second users. ### Claim 22 (depends on 6) The system of claim 6, wherein at least one of the plurality of first users broadcasts the second audio to a plurality of second users. ### Claim 23 (depends on 12) The system of claim 12, wherein the second audio is further modified by the first user to generate a third audio, wherein the third audio is broadcast to a plurality of second users. ### Claim 24 (depends on 12) The system of claim 12, wherein the first user broadcasts the second audio to a plurality of second users. ### Claim 25 (depends on 20) The method of claim 20 further comprising the step of: prior to the first user broadcasting the second audio and the first video to the plurality of second users, a third audio is generated by the first user and broadcast with the second audio to a plurality of second users. ### Claim 26 (depends on 25) The method of claim 25, wherein the plurality of second users are within a peer-to-peer group determined by the first user.
