The audio visualization method includes: determining whether the electronic device executes an audio/video program or not, where when the audio/video program is executed, an audio effect signal is generated; converting the audio effect signal into a two-channel signal and a multi-channel signal when the electronic device executes the audio/video program, where a channel count of the two-channel signal is less than that of the multi-channel signal; generating sound data according to the multi-channel signal when the electronic device is set to the silent mode; and generating an icon according to the sound data and presenting the icon on the screen. The disclosure also provides an audio visualization system. ## Claims ### Claim 1 An audio visualization method, applied to an electronic device with a screen and a function of a silent mode, the audio visualization method comprising: determining whether the electronic device executes an audio/video program or not, wherein when the audio/video program is executed, an audio effect signal is generated; converting the audio effect signal into a two-channel signal and a multi-channel signal when the electronic device executes the audio/video program, wherein a channel count of the two-channel signal is less than that of the multi-channel signal; generating sound data according to the multi-channel signal when the electronic device is set to the silent mode; and generating an icon according to the sound data and presenting the icon on the screen. ### Claim 2 (depends on 1) The audio visualization method according to claim 1, wherein the step of generating the icon according to the sound data and presenting the icon on the screen comprises rendering the icon on a scene picture of the audio/video program. ### Claim 3 (depends on 1) The audio visualization method according to claim 1, wherein the multi-channel signal is a 5.1-channel signal or a 7.1-channel signal. ### Claim 4 (depends on 1) The audio visualization method according to claim 1, wherein the sound data comprises audio source type data, audio source orientation data, audio source distance data, and audio source volume data. ### Claim 5 (depends on 4) The audio visualization method according to claim 4, wherein the icon has a first dimension and a second dimension, the first dimension corresponds to the audio source distance data, and the second dimension corresponds to the audio source volume data. ### Claim 6 (depends on 5) The audio visualization method according to claim 5, wherein the first dimension is a length of the icon, and the second dimension is a size of the icon. ### Claim 7 (depends on 1) The audio visualization method according to claim 1, wherein the step of generating the sound data according to the multi-channel signal comprises: providing a plurality of sound features, wherein each sound feature corresponds to an audio source type; and respectively filtering the multi-channel signal by using the plurality of sound features to generate the sound data. ### Claim 8 (depends on 1) The audio visualization method according to claim 1, wherein the icon is an arrow. ### Claim 9 (depends on 1) The audio visualization method according to claim 1, wherein the step of converting the audio effect signal into a multi-channel signal comprises: converting the audio effect signal into the two-channel signal; and simulating the multi-channel signal according to the two-channel signal. ### Claim 10 An audio visualization system, applied to an electronic device with a function of a silent mode, the system comprising: a screen; a processing unit, configured to execute an audio/video program, wherein when the audio/video program is executed, an audio effect signal is generated; an audio conversion unit, configured to receive the audio effect signal and convert the audio effect signal into a two-channel signal and a multi-channel signal; an audio analysis unit, configured to, when the electronic device is set to the silent mode, receive the multi-channel signal and generate sound data according to the multi-channel signal; and an icon generation unit, configured to generate an icon according to the sound data and present the icon on the screen.
