I never did audio forensics, but in the other side I am really expert in sound engineer. I am also a musician. I would like to transfer my knowledge in forensics.
Which are possible scenario and software?
best regards
It's a small community.
I started with training from Russia on sound principles and followed it up with software and hardware training in Canada, then vendor specific training in the US.
Investing in good equipment, like say a Dragon, they come up on EBAY every once in awhile and allow you to
move the playback head for azimuth adjustments. Like when someone says they erased a tape, but you still pick up the remnants of a conversation. Same as file slack.
There are a few pieces of software, which range from low cost all the way up to very expensive.
If you're serious about getting into this I'd be happy to refer you to a few good teachers, but all are not anywhere close to where you are at, and don't offer remote training.
I've got a really good ear and enjoy the enhancement aspect which you can do with any number of programs, even something like Audition (formerly cool edit pro) or in a pinch the DJ type software. Anything that lets you do db gain, spectral analysis and removal, stretching, speed up/ slow down.
Situations that could come up, 911 calls, body wire enhancement where there is ambient noise, speaker identification, telling how far someone was from a location based on the recording.
Hope this helps.

Cool, I had a similar background, after studying sonology I studied computer forensics, and it is wonderful combination.
About the tools, There are few expensive audio forensics tools around, but for the purpose of understanding, it helped me a lot to learn the basics of digital audio, sound synthesis, Fourier analysis, etc. Considering you are an audio engineer I assume you know all these topics. If I could suggest a free sound synthesis and analysis language, I prefer SUPER COLLIDER, it is a powerful OOP language where you can build De-clippers, De-noisers, analysis functions, all kinds of complicated filters, FFTs, and transform overtones as you wish.
Now, for audio(or media) forensics, just add to your technical knowledge a good forensics methodology in accordance to law(your state or country laws) and you are in…
ok, many thanks

Hello
Have you filtered noise from a telephone tap?
