Qrest is the Qrest Really Easy Studio Toolkit. Its purpose is to help any computer aided misician / composer / mixer.
It serves (for now) 2 main goals :
Guess the tempo of a piece of music by using its TAPTEMPO feature
Compute dealy times & LFO frequencies for the most common note durations, according to tempo & alteration
Qrest code is C++ and uses the Qt framework for all GUI stuff. All non-GUI related code is Qt-free, except for the timer used in TAPTEMPO feature.
