Here at CREATIVE FORENSIC SERVICES we use computers and audio software to aid in the Audio Tape Enhancement process. Audio Cassette and Micro Cassette tape is inherently noisy. Tape recorders as well as environment each play a part in creating their own noise levels. It is this noise level that veils the wanted audio. This is referred to as the signal to noise ratio or SNR. The SNR plays a pivotal role in the success of Audio Tape Enhancement.

Sometimes the SNR is so overwhelming that it can take days of analysis to reach an acceptable audibility. Other times it can be as simple as hiss removal and amplification. Sometimes a deposition or an old piece of evidence needs to be used again after many years in storage. This can cause many problems considering how it was stored and where. It may have been damaged somehow or it could just simply have faded and lost its edge after many years of neglect. Our goal in restoration is to repair this damage and restore the sound, which is now faint or distorted. In some cases it may be damaged beyond repair but not always.

"I remember doing a job for a person who had sent his cassette through the washing machine!"

You would think that that would have completely destroyed any audio on the tape. It actually did damage the recording but with careful analysis it was restored however not to its original state but well enough to be transcribed and used.

Vinyl Restoration

Old vinyl records would wear down and degrade usually acquiring many clicks and pops and scratches and surface noise that mask the recorded material
