... But let me try a mathematical approach (feel free to correct me): fluidsynth uses floats in the range [-1.0 ; 1.0]. Floats have a precision of about 10^-7 . Considering rounding errors that may occur during the bunch of operations that we apply to a single audio sample (voice mixing, panning, attenuating, reverb, chorus, IIR) we might end up with a precision of 10^-5 in worst case. Transforming this to a more handy 16 bit signed integer samples: 10^-5 * 32768 = 0.32768 . This is the relative sample quantization error that we make when using single precision. Let's just ceil this value, i.e. for every sample computed in single precision we may have an integer quantization error of +-1 . This is exaggerated and I doubt that this error is audible, but in any case: One could just take any favorite piece of audio and apply a random quantization error of +-1 to each and every sample. Experimentally increase this error until some difference to the original waveform is audible. (Btw. for the old autotools build system enable-floats was actually true by default. Not sure whether this was intentionally changed when switching to cmake.)
