Looping an ADX

A Question for Sonic Adventure 2

Does anybody know how to make an adx loop? If possible, is there any way to see the looping locations of the sound files already in sa2?

    ADX files already contain the loop within them. The loop values are based on “samples”. 

    I already uploaded a tool for this, which has everything you need to create a looping ADX.
    Don’t judge. Just experience

    You do have to have a good set of ears for this, a audio editing program like Audacity, and note where the samples that represent the loop are to use the tool.

    SA2's ADX files are 16-bit 32000Hz WAV PCM. The Tool -[DEXTERITY]- mentioned will show you the current loop points*, so make note of them. Do know that music at a higher or lower frequency will alter the sample rates.

    *Correction: The encoder will show the beginning and end samples, the player shows the end samples, or you could use the loop points from

    I learned how to do it the hard way back in 2014 with my New ADX mod, it was made using StoE (Start to End) Looping, and PES Sound Converter, I had to edit the songs so they would sound good during looping (This method also resulted in a smaller file size).

    Which I remade around the time Forces came out. This one uses more up to date actual sample looping, and the CRI ADX Tools. I had all the files to remake it, but I didn't make all the loop points myself, I used SmashCustomMusic's archive (which has the loop points and KHz for the audio) for most of them.
