Significantly smaller files.
WAV is a lossless format that prioritizes fidelity over size. Converting to AVI introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
WHY CONVERT
01
WAV is a lossless format that prioritizes fidelity over size. Converting to AVI introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
02
AVI is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when WAV reaches an unprepared pipeline.
03
AVI files are typically smaller than their WAV counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
