Forensic
Audio Restoration and Enhancement Services
I am now offering high quality Forensic Audio
Restoration and Enhancement Services to the law enforcement and legal
communities.
New and
powerful computer technologies now enable audio recordings to be rendered much
more audible, and with far greater clarity, than was previously possible.
I apply
the highest standards of forensic analysis to this new state-of-the-art
process. An important component of sound forensic analysis is that each step in
the process be documented clearly and in detail, so that the analysis can be
duplicated by other experts if needed as part of the development of a case and
its presentation at trial.
How
does this service work?
You provide me with the
original recording or a good duplicate copy if the original is not
available.
- I then digitize the audio
stream. This provides a baseline that will not change with repeated
listening.
Using specialized forensic
audio software and hardware, I make the relevant portions of the recording
clearer and more audible. I can also isolate certain parts of the
recording for ease of use in court proceedings, and can slow down or speed
up the recording without changing the pitch.
- I then produce a CD
containing the original recording and the restored version as separate
tracks. Any isolated audio will aso be included as separate tracks, as
well. This CD can be played in any CD player and can be copied using
standard CD copying software.
This
process is surprising rapid and the costs quite reasonable.
I also
offer other specialized audio-based services. These include spectrographic
voice comparison (aka voice-printing), selective removal or masking of audio
for use in court, and gunshot or other impulse sound analysis.
