All your music mods should be using the appropriate sample rate to avoid distortions and glitches.'' | ||

Select a portion of the beginning of the song, find out precisely what ''sample'' you have selected it to (A sample is the most precise unit of song editing, as milliseconds are too imprecise here), and note it down. Then copy/paste your selection onto a new file and give it a fade in. After that, copy that file and paste mix it into the last part of the original song you are using so the intro fades in while the outro fades out. | Select a portion of the beginning of the song, find out precisely what ''sample'' you have selected it to (A sample is the most precise unit of song editing, as milliseconds are too imprecise here), and note it down.

If for some reason the editor you're using doesn't show the ''sample'', get as accurate a time as possible (down to the one-thousanths of a second), and multiply that time, in seconds, by the sample rate of the file (e.g. 7.052 seconds * 48000Hz = 338,496 sample). | ||
IMPORTANT: When you are creating a loop, you must ensure that the start point and end point of the loop are ideally when the wave form reaches 0 amplitude, and one wave is coming up while the other is going down, to ensure optimal flow. This is how you achieve seamless loops. Failure to adhere to these principles means skips, clicks, 'pops' or static will be heard when the song loops. | IMPORTANT: When you are creating a loop, you must ensure that the start point and end point of the loop are ideally when the wave form reaches 0 amplitude, and one wave is coming up while the other is going down, to ensure optimal flow.

Some tracks need to be loaded in by a one-second prefetch that contains compressed data of the BFSTM, and you can find these by analysing the list of .bars file to see if your track has one. All sound effects and battle themes have a bfstp stored inside a respective .bars file, e.g: ''GuardianBGM.bars'' contains the prefetches for the main Guardian theme and outro. Assuming you followed the same looping steps as mentioned above, you should have a Guardian_Main theme that loops, and a Guardian_Outro that does not loop (select 'Keep as non-looping' in Looping Audio Converter). Once the new BFSTMs have been made, you should follow the [https://gamebanana.com/tuts/12856 bfstp fixer] method, where you place bfstpfixer.py, BCFSTM-BCFWAV-Converter, your BFSTMs, and a .bat file with the following code: | Some tracks need to be loaded in by a one-second prefetch that contains compressed data of the BFSTM, and you can find these by analysing the list of .bars file to see if your track has one.
