The purpose of this page is to test the support for a simple HTML5 <audio> tag (without scripting),
combined with different audio codecs, and different lengths of sounds, over HTTP as well as HTTPS.
Sounds are indeed truncated by some browsers, which is not acceptable for short sounds, as they may not be heard at all
(a lot in Firefox 3.6, Android browser 2.3; a bit in Firefox 5; fine in Android browser 4.0.3 and Firefox 13).
Some clicks and other sound distortions appear in some browsers (Firefox 5).
Sounds using the WebM format cannot be played more than once in some browsers (Firefox 13, Opera 12).
HTML5 audio does not seem to work over HTTPS in Android browser (2.3.3 - fine with 4.0.3) and Opera Mobile (11.10 - fine in 12).
Multiple formats to satisfy all browsers
In order to cover all my use-cases in 2011, MP3 + Ogg/Vorbis is needed with some trailing silence:
1 second of sound, followed by 1 second of silence
