[. . . ] Paste will similarly identify independent leading and trailing blend regions around the selection or insertion point. Paste will then compare its leading blend region with the leading blend region of the Clipboard and choose the smallest. Note that blending occurs outside of the original selection and outside of the Paste's selection. In order to blend the result, samples on both side of the beginning of the selection are merged with samples on both sides of the ending selection, provided that blending is enabled and there is a non-zero blend time. It must be noted, therefore, that cutting some samples does not necessarily completely remove them. To completely remove the center-most samples, the selection size must be larger than the blend time. Blending in Clear works the same as blending in Cut. 32 Normally, when Pasting or Mixing with an insertion point, the new data is inserted before the first sample of the group of samples represented by the pixel under the insertion point. The exception to this rule is when the insertion point is on the last pixel in the soundfile window. In that case, the new data is added after the last sample in the soundfile. Blending occurs between the end of the original sound and the pasted data. ADJUSTING THE BLEND PARAMETERS Infinity allows the length and taper of the crossfade used in edits to be adjusted. dialog will evoke the Edit Blend Settings dialog shown below. Blend Time: To change the length of the crossfade, use the Blend Time scroll bar or type directly into the text box to adjust the duration. The most useful range for normal editing functions is from 10 to 50 milliseconds. (The scroll bar has exponential scaling so there is plenty of resolution around the most useful settings. ) The illustration below shows the effect of changing the Blend Time control. BLEND TIME =0 MILLISECONDS BLEND TIME =10 MILLISECONDS BLEND TIME =25 MILLISECONDS 33 Blend Taper: The slope of the crossfade can be changed by using the Blend Taper scroll bar or text box. The illustration below shows the effect of changing the Blend Taper control. BLEND TAPER= 100 EQUAL POWER BLEND TAPER= 0 LINEAR Linear taper should be used for editing simple periodic waveforms like solo instruments. Equal power taper should be used when editing complex nonperiodic waveforms like string sections or noise. SAVING THE SOUNDFILE SAVE Because Infinity uses disk based documents, changes to the soundfile are saved as they occur. The Save command in the Edit menu updates the backup file (if one exists) so that a Revert to Backup command will revert the soundfile to the most recently saved backup. The Save command in the Edit menu is selectable after a change has been made in the soundfile. If the soundfile has been changed and a backup file exists, closing the soundfile will cause the following dialog to appear. SAVE A COPY. . . command to save the soundfile in a different folder, with a different file name, or in a different file format. This command is useful to make a series of samples for later comparison. 34 To use the Save a Copy. . . [. . . ] Check that the Fundamental (Hz): number is within a pixel's accuracy of the Hertz number on the floating palette. If you had checked MIDI Note you either specified the wrong note or the data is not tuned to A3 = 440Hz equal tempered scale. The MIDI note was used as an initial guide by the pitch detection algorithm. Unfortunately, if you process a short loop (less than 20 cycles), the Pitch Detection algorithm will not be precise and the result may be slightly out of tune. [. . . ]
