    Default Waveform Plug-in

    Hello,

    I would love to see a plugin that compares the waveforms of .wav files. I often have to compare audio signals and a beyond compare plugin would make life much simpler. Perhaps it would be best have both waveforms on top of each other, but being on the left and right(or top and bottom) of the screen should also be cool.

    great software,

    thanks,
    Aristotel

    Maybe this one could work together with a more robust MP3 viewer? Right now that viewer only displays differences in size or tags -- I've had two identically-sized MP3 files with the same tags that only displayed with the size field in red, showing that they were different but not really offering a way to compare 'em further.

    Maybe an interim solution would be to let you transfer the comparison to the hex viewer -- but a hex comparison is of only limited use for those types of files. In the case above, the difference was only that one was normalized and one was not.

    The wave form is just one appareance of the audio but not the most human revelant. It would be better to show spectrum differences. They are also more visible than waveform and better to make some "approximate" comparison or find part of a wave file in another one.

    An example can be seeing using Audacity (free software).

    To generate it you need to compute the 1D (Fast) Fourrier Transform. MP3 does it for each 20ms block about. Here it may be over some longuer period.
