85% cpu about. no clicks.<br>

One slight tweak: if you type "sudo chmod 4755 /usr/bin/pd" you will<br>
probably be able to use the mouse clicklessly (at some expense to security!)<br>
<br>
This will be unnecessary in release 0.44...<br>

Dear List,<br>
<br>
I managed to get the phase vocoder working on my Raspberry Pi, with the<br>
standard Raspbian wheezy distro.<br>
It works ok under the following conditions :<br>
- no GUI activity (even moving the mouse results in awful scratches)<br>
- the "delay" in Pd is set to at least 50ms<br>
- 224 Mb of RAM is allocated to the CPU.<br>
<br>
All this using the internal audio output.<br>
<br>
This is quite encouraging...<br>
<br>
Cheers,<br>
