I have 90 html files where an audio file is played (wrong link), I need to change the src of the audio file in each one of these files.

from 

```
<embed src="../audio/" autostart=false width=0 height=0 id="sound1" enablejavascript="true">

```

to:

file 1:

```
<embed src="../audio/1.mp3" autostart=false width=0 height=0 id="sound1" enablejavascript="true">

```

file 2:

```
<embed src="../audio/2.mp3" autostart=false width=0 height=0 id="sound1" enablejavascript="true">

```

...

Any suggestions for an automated approach? 
Thanks 

Later edit:

The new src is different for each file... any possibilities to fill this automated for each file? for file1 -> src1, file2 -> src2 ...
