Sampling graph display is broken

Sampling graph display when recording or playing back audio is broken

[kmaclean]

Sampling Graph is now working, but there are some problems:

• Sun's JavaSoundDemo? does not display the sampling graph as the user makes a recording - it only appears after the recording has been completed - this is still useful to allow the use to see if there are any problems with the waveform (speech too loud or not loud enough)
• The tracking bar on the VoxForge? demo is not in synch with speech
• the wavform display only works for the most recent recording and playback. If you try to play back some other audio, the wavform display does not reflect the new audio selection

[kmaclean]

Sometimes the tracking bar does not appear when playing back audio

[kmaclean]

If you click record and let it record silence for a few seconds, and then click record on the same line, but this time record audio, then the tracking bar will display ... otherwise it does not.

[kmaclean]

It seems to be using the duration value for the silence that was recorded previously, causing the tracking bar to be not in synch with actual audio (either too fast or too slow)

[kmaclean]

CapturePlayback? - waveform now corresponds for each prompt line, but the audio plays before the updated waveform gets displayed.

• need to at least clear the wavform before tha audio plays (i.e. blank waveform display on play of a new line) or
• read the file once to display the wavform, and then play the audio

[kmaclean]

waveform now corresponds for each prompt line and it now displays properly - see changeset:2303

[kmaclean]

trackinging bar is still not synched with audio (either too fast or too slow). It only appears when you play a prompt (since waveform only displays after audio capture is completed). It never appears for prompt line 1??? And appears intermittently for the other prompts.

re: tracking bar - see ticket #215
