Three Centigram ADPCM file formats are supported under Vox Studio. All are ADPCM variants sampled at 8 KHz.
The supported Centigram formats are:
32K ADPCM
24K ADPCM
16K ADPCM
These formats have a file header that contains all the necessary information for decompression. Therefore, when Vox Studio opens such a file, it will not ask you to enter additional information such as sample rate or coding algorithm.
