ImageDJ, basically a question not a joke

[Rainer M. Engel]

Are there any plugins or I/O stuff for audio files?

I would like to create waveform or spectrograph images for audio files.
It doesn't has to be fancy like this

The plan would be to do audio analysis in the image domain and perhaps
be able to perform basic trimming on the audio source files.

Maybe I only wonder if anyone out there is using ImageJ on audio
forensic for example. At least this would make sense to me, but I didn't
find anything about it around ImageJ.

Concerning Java and audio I found:
http://code.google.com/p/musicg/        Java API for audio analysing

Any thoughts, opinions and comments are very much welcomed.

Thank you.

Best regards,
Rainer

For waveforms you could use Audacity and save as Raw, then load the Raw file
with a macro (that you need to write).

But given that waveforms, spectrograms and other visualiastions are already
possible in Audacity maybe it is not worth writing plugins for IJ which was
not made to handle sound files anyway. Audacity has all sort of plugins
developed too (specially the LADSPA plugins) which should be worth looking at.

Hope this helps

There is also the Ardour Digital Audio Workstation for Linux, this is
fantastic and very flexible.

It offers all the LADSPA plugins, works with the likes of JackRack etc.

Best,
Ed

Thank you both for your replies. I recovered "Sonic Visualiser"
http://sonicvisualiser.org, which also offers analysis and batch
annotation operations via available plugins.

Also interesting seems the forth and back conversion between audio and
spectrogram.
http://arss.sourceforge.net/

My request was not about re-inventing audio editing, but although I
found some interesting tools and options, much seems to be only GUI
based or otherwise limited.

I'll try the RAW-Idea Gabriel mentioned though. SoX might be much more
suitable for automated wav -> raw conversion but I'll have to see.

Best Regards,
Rainer
