I have a corpus of recorded interviews and would like know what Windows 7 software (preferably commercial because it will be bought by administration of my institution, which is a bit reluctant to free software) is best suited for the following:
while listening to the sound (if possible at a slower progression rate) either click with the mouse, or press a keyboard key, to introduce a mark on the fly. The marks should be retrievable as a list of labels and timestamps.
My need for placing the mark is to timestamp the moment when the speaker changes (there are always only two speakers), and it should be as precise as possible.
If possible, the mark should be displayed on the spectrogram and it should contain the value of an integer variable, automatically incremented for each new mark placed (this is not absolutely necessary, but useful because while placing the marks I have a transcribed version of the interview before my eyes and in this transcribed version I have speaker changes numbered).
I have done this already using Amadeus Lite on the Mac and listening to the interview at 50% of the normal speed. It worked more-or-less well because Amadeus asks for the mark label contents with a dialog which I had to dismiss and this made me stop very often, go back, and repair the mark. No somebody else will work on this corpus, using a Windows machine.
