-// This convolution filter can be used with inpulse responses files
+// This convolution filter can be used with finite impulse response (IR) files
 // to apply almost any correction to the audio signal, like frequency and phase correction.
 // For example you could measure (with a good microphone and a sweep-sine) the frequency response of your speakers + room,
 // and apply a correction to get a flat response curve.
 // Long impulse response files require lots of floating-point processing!
+//
+// Convolution is applied to each output channel at the output rate.
+//   Thus, your IR files must match the output rate and match the output channel count or are mono.
