BASS Spectrum Analyzer
This plugin utilizes the BASS audio library to return a FFT representation of an audio stream. Use at your own risk, it is not threaded and will cause delays to the main thread when starting audio streams.
Natives/Documentation:
Most natives return 1 on success, 0 on failure, use BASS_ErrorGetCode() to get failure reason
Code:
native BASS_Init(); native BASS_Free(); native BASS_PlayStream(url[]); // Returns the handle ID created native BASS_StopStream(handle); native BASS_ErrorGetCode(); native BASS_ChannelGetData(handle, Float:buffer[], length); //Note: length does not match documentation syntax, see include for which are defined native BASS_ChannelGetLevel(handle, &left, &right); native BASS_ChannelGetLength(handle); // Returns channel length in seconds
Examples provided are meant to be proof-of-concepts, they would not be realistic to use in a production environment due to the high amount of bandwidth required. Try on a local server.

A video using the same concept (but a different library at the time):

(The most suitable example of what could be used on a live server.)
You have all the data made available from the library function so you could probably make something much cooler than what I did, and something that would actually work in a production environment.

(but I think there's non need to analyze sound, just do some random Z adjustments and voila we got a pseudo bas analizer)
Amazing work 
Going to be fun to play around with.
