VOC in het kort
VOC
VOC belongs to the DOS and early Windows multimedia period, when sound-card vendors heavily influenced both audio capabilities and file-format habits in software distribution.
SLN in het kort
SLN
Telephony systems often value simple, predictable raw media assets over consumer-facing container polish, which is why formats like SLN remain operationally relevant long after their user-facing visibility disappears.
