You can use something like sox (for ladspa plugins) or lv2file (for lv2 plugins) to run any sort of autotune plugin you want on a wav file.<br><br>Jeremy<br><br><div class="gmail_quote">On Tue, Sep 25, 2012 at 2:21 AM, Nils Gey <span dir="ltr">&lt;<a href="mailto:list@nilsgey.de" target="_blank">list@nilsgey.de</a>&gt;</span> wrote:<br>

<br>
I have samples here, single-note recordings from instruments, that need tuning.<br>
I am looking for a permanent/destructive way to do that.<br>
I can do the batch processing part myself so I only need a hint how to do it for one file.<br>
<br>
The file(s) are nearly correctly tuned and I already know what it is supposed to be, if that helps.<br>
Example: I have a file resembling the midi a4 which should be 440hz, but maybe it is 430 to 450.<br>
So the optimal input would be: &quot;Tune this file to a4&quot; where the analysis of the actual frequency is done by a program.<br>
<br>
Quality is the top priority. Since the tuning is very fine I don&#39;t care if the speed of the recording changes or not. I take what sounds best.<br>
<br>
So, any command line tool available for that? If not a GUI tool is fine as well.<br>
