        As the udp sender has no idea about connected clients it
        sends the audio file header periodically if necessary. This
-       option is used to specify the duration of the interval between
-       sending the header. Shorter values decrease the average time
-       clients have to wait before being able to start playback,
-       but this also increases the amount network traffic. Note
-       that this affects only ogg vorbis streams as this is the only
-       audio format that needs an audio file header.
+       option specifies the duration between subsequent headers are
+       sent. Smaller values decrease the average time clients have
+       to wait before starting playback, larger values decrease
+       network traffic.
+
+       Note that this affects only ogg/* and wma streams. Other
+       audio formats, including mp3, don't need an audio file header.
