Long stream captures arrive large; this tool re-encodes the AAC at a lower bitrate to cut the size, right in the browser. Speech-heavy radio content compresses especially well.
If the goal is archiving rather than squeezing, wrapping the stream into M4A without re-encoding preserves full quality and adds metadata support. Compress when size is the constraint; convert when organization is.
