9. semitones 2 octaves Pitch refers to the relative pitch of the current sample chunk being played If for example the pitch sliders are left at their default positions 0 then there will be no pitch difference in the playback of the audio stream Thus it is recommended that the pitch sliders remain untouched if no pitch manipulation is desired Joel Glanfield User s Manual 14 09 2005 Pitch Interpolation Interpolation is also an option with respect to the Pitch parameter The start slider specifies the pitch of the very first audio chunk to be played while the end slider specifies the pitch of the very last audio chunk to be played The pitch of intermediate audio chunks is interpolated based on the start and end values specified by the user If no interpolation is desired it is up to the user to ensure that both sliders are at the same position For example if the user wishes to play the audio stream at one octave above the original pitch throughout the entire playback then both sliders should be set to 12 semitones Pitch Rounding This option can be toggled on off via the round button found on the Pitch parameter panel When on i e when the button is red any calculated pitch will be rounded to the nearest semitone during interpolation only When off i e when the button is green the calculated floating point pitch value as calculated during interpolation will be used as the pi
10. tch for the current audio chunk Gain The following image shows the Gain parameter as found on the interface of the plug in Gain values are simply between 0 00 and 1 00 and refer to how much the current sample chunk s volume should be manipulated For example if the current Gain value is 1 00 then the sample values throughout the current audio chunk will be multiplied by 1 00 thus resulting in no change However if the current Gain value is 0 5 then each sample value throughout the current audio chunk would be multiplied by 0 5 thus halving the amplitude which in turn implies half the normal playback volume Gain Interpolation Interpolation is also an option with respect to the Gain parameter The start slider specifies the gain of the very first audio chunk to be played while the end slider specifies the gain of the very last audio chunk to be played The gain of intermediate audio chunks is interpolated based on the start and end values specified by the user If no interpolation is desired it is up to the user to ensure that both sliders are at the same position For example if the user wishes to play the audio stream at half the volume throughout the entire audio playback then both the start and end Gain sliders should be set to 0 5 Joel Glanfield User s Manual 14 09 2005 CHAPTER 4 BUTTON PARAMETERS This section of the manual will describe the parameters and functions controlled by the buttons found on
