The original sound source is not affected in the process; it is used solely for playback in the appropriate device to transfer everything to the digital domain. The forensic restoration will then be applied to the digital copy. Sound sources include surveillance recordings, (tapes or digital), taped police interrogations, voice mails, wiretaps, mini voice recorders, body wires, telephone conversations, speeches, interviews and lectures, and many other.

Whenever possible, it is preferable to transfer the source using the original recording. A copy will have a loss of fidelity; aside from this, it is better to use the original, especially if it goes to courts. In many cases, we can restore from damaged tapes, but it depends on the severity of the damage.

Forensic restoration is a process whereby audio from a low quality recording is enhanced to make it clearer. Through forensic restoration, light distortion can be improved, making distorted voice more articulate. Background noise, like streetcar and car noise, dishes clattering, doors being shut, among other sounds, can be reduced and sometimes even eliminated. Forensic restoration also covers the analysis of sound sources and can establish if a sound source was tampered with or whether the recording was edited.

The following is an example of an audio recording in the original state and after the forensic restoration. Please note the reduction of the background noise, which improves the intelligibility and the reduction of a door being shut of.

In order to know exactly what can be done with your sound source and the cost of it, please call the studio and make an appointment. We do not provide forensic restoration quotes over the phone, as we need to hear first the sound source in order to estimate the amount of work.

The final processed project will be burnt on CD, unless the customer wants a different audio format. Copies are provided as the customer requires.
