00100 INFORMATION ON K AND KI FILES
00200
00300 KMAIN revised from KI
00400 This program uses the procedures in KAUD to speak and to record utterances
00500 and the procedures in TRACK to obtain FFT's and tabulate formants.
00600
00700 KEDIT.SAI revised from KIEDIT and the earlier KINAME
00800 This program allows one to hear a file, to create a new file and edit into
00900 it selected portions of the original file, saving the name of the neqw
01000 file in KILIST.SIX.

01200 TRACK.SAI A simplified procedure for thacking formants when only
01300 vowels are to be analysed.
01400 The program first locates a vowel region, it then skips ahead a short
01500 distance, now set at 200 saamples, then it locates the 3 largest peaks
01600 in a 512 sample region and applies some simple tests to pick 2 of these
01700 peaks that appear to be a pitch period appart. An FFT is taken of this
01800 interval usinf FORM(1), then using PREPARE to locate the first three
01900 formants. At present these are simply tabulated.
