Streaming Media introduces worlds of options. Lower bitrates are able
to reach more users limited by connection speed, but at the cost of quality.
Newer CODECs tend to offer better quality, but often at the cost of compatibility.
Different formats support varying features, but only in proprietary software.
The samples on this page use CODECs designed to best reproduce the human voice.
