Bug description:
Binary package hint: ubuntu-sounds
The instantaneous beep in the default Ubuntu 9.10 preview install has
been switched to a slow firing, and slow to repeat sound:
/usr/share/sounds/ubuntu/stereo/bell.ogg
the easiest way to cause this sound to be played in anger is to open a
Terminal (eg. gnome-terminal) and hit the backspace.
There is an audible delay in the latency until the sound is played and
approximately 1 second until the sound is replayed (despite the key
repeat likely firing at over 25 Hz.
Viewing the Vorbis file with ogginfo and mhWavedit shows that it is is
approximately 900 milliseconds in length!
$ ogginfo /usr/share/sounds/ubuntu/stereo/bell.ogg | grep Playback
Playback length: 0m:00.882s
The file consists of ~50 milliseconds of silence, ~200 milliseconds of
actual sound and then a further ~650 milliseconds of silence.
Ideally the white space should be trimmed to the *absolute maximum*.
The sound needs to play *immediately* to meet the requirements set of
the HIG for interactive feedback (100 millisecond upper bound).
If further delays are being introduced by the Vorbis loading then this
sound (which should be immediate and responsive) should probably be
converted to an uncompressed format.
Failing that, the sound could be reverted to the previous short and
quick 'bip' sound used previously.
