How to downsample .AFS files

Check out different way to downsample .AFS files.

Software Requirements:

• Afs_extract
• Adx2wav
  
• CoolEdit2k
  
• Wav2adx
  
• Afslnk
  

Make a directory on your hard disk, C:\Selfboot\Downsample

Place Afs_extract ,Adx2wav ,Wav2adx & Afslnk to that directory.

Extract .AFS file which you want to downsample with ISOBuster to directory c:\Selfboot\Downsample

eg. Bgm.afs(109mb) "DynamtieC*p2 -US"

Please verify that you have all of these files before proceeding.

Extract .AFS to each .ADX files

To do this, Open up a DOS Window and type in the following commands:

cd c:\selfboot\downsample 
Afs_extract Bgm.afs

After executing these commands, Afs_extract should have converted .AFS file to each .ADX files and extension eg. "Bgm_00.adx => Bgm_29.adx"

Del *.AFS

Convert .ADX to .WAV files

To do this, Open up a DOS Window and type in the following commands:

cd c:\selfboot\downsample 
Adx2wav *.adx

After executing these commands, Adx2wav should have converted .ADX files to .WAV files and extension eg. "Bgm_00.wav => Bgm_29.wav"

Del *.ADX

type in the following commands from DOS Window:

cd c:\selfboot\downsample 
Adxencd *.wav -lpe

these commands should have converted .WAV files to .ADX files "loop at the end"

Combine each .ADX to a single .AFS file

To do this, Open up a DOS Window and type in the following commands:

cd c:\selfboot\downsample 
dir /b /o /s *.adx > ADXTXT.TXT 
Afslnk ADXTXT.txt Bgm.afs

After executing these commands, Afslnk should have combined .ADX files to a single .AFS file and extension. eg. "Bgm.afs"
