Description

FreqTweak is FFT-based, and supports up to 4 channels. An FFT analysis is applied to each audio channel, and every individual frequency band can have a different effect applied to it. In version 0.6.1 the following effects are available:

gollark: Why are you puttinG COMMENTS iN gOLfCode?
gollark: There are some bad test cases.
gollark: You're obviously not allowed to open arbitrary TCP sockets in the browser, and can't even have your thing connect to random local HTTP servers, but you can try HTTP/websockets and see what error comes back and/or use timing data.
gollark: I'm also looking into, for evil purposes, in-browser port-scanning.
