Hello,<br>
<br>
I was wondering. Is there some way to do the following in PulseAudio:<br><br>SELECTIVE SOUND AMPLIFICATION BASED ON SOUND FREQUENCY.<br><br>
I know I can do "normal" amplification which will raise all frequencies across range equally.<br>
<br>
However, for hard of hearing people it might be better to raise some frequencies more than other.
<br>
<br>
The same thing goes for the older people who usually lose the high frequency hearing over the time.<br>
<br>
Here's a sample audiogram:<br>

<br>
If we were use it as guide, we would need to amplify:<br>
* 2k frequency by 10db, <br>
* 4k frequency by 40db, and <br>
* 8k frequency by 20db<br clear="all">
<br>
and hopefully all frequencies in between linearly by some value in between.
<br>
<br>
after that simple amplification by 10db across range would be a Finish.<br>
<br>Can this be done on PC under Linux? without using DSP? I tried to Google for this but I got no useful hits.<br><br>Any idea? Pointers to better mailing list to ask this question?<br><br>-- <br>Adam Sulmicki<br><a href="http://www.eax.com">
