Quite often audio and video survellience recordings are done in adverse circumstances and consequently the end results can be difficult to comprehend and be of little use in dispute resolution. With careful treatment by our knowledgeable staff the end results can usually be vastly improved.
The goal is to make speech in covert recordings more understandable by improving the quality of the audio so it may be used for a transcript or playback at a trial.
Recordings typically have a very poor signal to noise ratio, and speech is often masked by buzzes, high or low frequency noises and impulse noises such as pops and crackles.
Sometimes the recording device also introduces problems such as tape saturation, clipping, hum or distortion. This is analysed initially by trained ear (an art in itself) to isolate problems.
The audio is digitised, sampled and measured. Filters are used to enhance the audio to a point where transcription is possible and/or the target sounds can be heard more clearly.
