Frequently asked questions about forensic audio

We serve government, police, the legal profession and private individuals. Jobs can be simple or complex, and the purpose of the initial evaluation is to determine what might be acheived and at what cost. Here are some typical questions:

Q: What is "forensic audio"?

It's the magic that fixes up audio that's very hard or near impossible to hear. For example a conversation that is drowned out by the noise of a car or wind or aircon. Or a poor recording on a messaging service or mobile phone. At an advanced level it can even help you figure out who's present in a room and the relative position of each person.

Q: What problems can you fix?

It depends on many factors, but most people are surprised what can be achieved. The audio we deal with was not recorded in ideal conditions. There can be hums, buzzes, motors, air conditioning, wind, pops and crackles - and what is called 'broadband' noise. There may be problems with the recording device, or the distance between the device and the sounds we are interested in. Most times you can barely hear what you want to hear, and that's what we attempt to fix. It is sometimes asserted that an audio file has been tampered with, and we can often prove or disprove that this is the case.

Q: How do you work your magic?

It's part art and part technology. You have to know what you're looking to take out, suppress or enhance to better hear the sounds you're interested in. We use the same software programmes as the FBI. And pro hardware devices, a purpose built audio studio and seasoned audio engineers who have worked on complex cases.

Q: What are the outcomes?

Our aim is to extract the best possible recording that we can. This can be used for a written transcript, be used as evidence to settle a matter, or to be played back in court for a trial. As audio and video media is relied upon more and more for dispute resolution we're constantly updating our skills and equipment to provide useful outcomes.

Q: How long will the assessment process take?

We aim to provide a preliminary assessment within 2 working days from receipt (Perth, Australia time).

Q: How long will the work take to complete?

The first step is to complete the assessment process. Due to the varied nature of this type of work we will then provide an estimate of time to complete the work and estimated total costs.

Q: Can you appear in Court?

Yes, we have provided expert witness testimonies at both the WA District & Supreme Court. Costs & suitable appearance dates need to be determined.

Q: Due you provide Tax Invoices?

Yes, and payment in full is required before release of final reports.

Q: What audio master do you require?

We prefer the untouched original audio or a least a verified copy of the original audio.

We can handle virtually all audio file types and analogue tapes including mini and micro cassettes.

Q: What type of audio processing can be done?

We have several processes including, Audio Restoration & repair, Audio Enhancing and Audio Analysis. Some or all of these processes may be used on a project.
