the zone afterwards.

This function has 3 stages:Stage 1: Obtain the next speed based on the mode. Normal speeds have big gaps and "best

zone" speeds have tiny gaps.Stage 2: Determine what zone this speed is in. If in range, set the file's sample rate and bytes

per second values accordinglyIf at the end of the normal speeds, restart from the beginning and do the "best zone" speeds.Stage 3: Set flags and essential in-file data. This is needed to determine what file to use.*/

void CreateOutputFiles(){

/*This function reads any input files and writes the output based on the speeds used.

There are 4 stages:Stage 1: Obtain the speed to process. Do the normal speeds first then the "best zone" speeds.Use a while loop and the FindNextSampleRate() function for this.Stage 2: Read the source file upon a zone change.If the next speed is in the same zone as the current, don't read the source file.Stage 3: Determine the amount of progress made. The normal, best, and overall progress

should be indicated.The actual completion is based solely on the speeds rather than the number completed since

it's quite erratic.The formula is

"log10(CurrentSpeed/NormalSpeedsStart)/log10(NormalSpeedsEnd/NormalSpeedsStart)".For overall, use a weighted average - 1 part normal, 5 parts best (completing normal means

25% overall completion).The DOS filler characters are used for this, 20 (space; 0), B0 (1/2), B1 (1), B2 (1 1/2), and DB

(2).Each "block" is 2 percentage units so 50 are needed. For 13.2% completion, 6 fulls (DB) and a

half (B1) are used.Stage 4: Write the data to disk as a WAV file.

The format is in the "[speed] [song name].wav" format where [speed] is a 6-digit number withleading zeros.
