SOU

SOU - 8-bit unsigned integer PCM RAW Audio

The SOU extension identifies files commonly known as SOU - 8-bit unsigned integer PCM RAW Audio. It carries low-level audio samples with limited container information, so software may need the correct sample rate, bit depth, or codec assumptions. Audio utilities use those settings to interpret, play, or convert the data correctly.
