Avalon 6.4 and above can use adaptive bitrate streaming to offer an 'auto' quality level during playback. Adaptive streaming works by monitoring network bandwidth and adjusting playback quality automatically. This results in minimal buffering time (i.e. waiting for a video to partially download before playing) and consistent playback for both high- and low-quality connections.
The adaptive streaming option can be viewed using the playback quality selector, and can be seen alongside the other quality options that correspond to each streaming derivative.
When embedding audio files from an Avalon instance, the playback quality selector has been removed from the audio player (see image below). The playback quality is set to "auto" by default, and the removal of the selector only occurs in an embedded context.
