The Pitch Bend, Vibrato and Vib Speed parameters control these effects. I suggest you ensure you have the 32-bit GSnap from this page You could also try quitting Audacity then deleting your Audacity pluginsettings.cfg file. This sets the frequency of A above middle C.Īdditionally, GSnap will respond to pitch-bend and modulation MIDI messages to apply pitch-bend and vibrato. GSnap cant be used in Audacity when recording - Audacity does not accept MIDI input. The pitch-detection and correction can be made to use a different reference frequency using the Calibrate parameter. The GUI shows the snap-notes and regions in effect at any time. It defines a region around each snap-note that will be corrected to that note. The Threshold parameter sets the largest pitch-shift that will be applied to the input. Fixed scale correction has a fixed set of snap-notes, while MIDI correction is controlled in real time by MIDI data. There are two modes of pitch correction: fixed scale and MIDI. Once a pitch has been determined, GSnap applies the specified pitch-correction. The default value should be fine in most cases. Lower values for Speed will allow faster pitch-detection, but will increase the chance of false detection. The Speed parameter sets the number of wave repetitions required for positive pitch-detection. Also, the Gate parameter should be set so that the pitch-detector ignores background noise during "silent" passages. The Min Freq and Max Freq parameters help the pitch-detector by narrowing the range of frequencies it needs to consider. GSnap starts off by detecting the pitch of the incoming audio. Effect plug-ins should be placed after GSnap in the signal chain. For example, a clean, mono vocal recording, without excessive noise or reverb. It can be used subtly to correct the pitch of a vocal, or, with more extreme settings, to create a robot-voice effect.įor GSnap to work effectively, the input signal should be monophonic, at a good level and reasonably noise-free.
