Audio and Video Enhancement
1. Audio (from any source)
Tapes and other recordings can be enhanced to try to improve both the "listenability" and intelligibility of poor quality recordings - potential problems can arise from:
Overtalk
Poor quality equipment
Equipment or media malfunction
Distance from microphone
Interference (e.g. GSM noise)
Background or competing noise
Damaged tape or disc
Disguised or changed voice
Wrong speed
Copy of a copy of a copy ...
Noise Removal - depending upon the nature of the noise contamination of a noisy recording, it is often possible to remove extraneous clicks, hiss, hum and some background noise. Results can sometimes be extremely dramatic! However, it must also be understood that not all recordings are amenable to enhancement.
Selective Amplification - quieter areas of a recording (for example the voice of the distant speaker in a telephone conversation) can be amplified sufficiently to render speech or other sounds intelligible, whilst not increasing the amplitude of the louder or nearer voices or sounds.
2. Video (from any source)
For video recordings, in addition to the procedures listed above, we can also carry out:
Clarification
Highlighting
Obscuring
De-multiplexing (from CCTV)
Converging (from CCTV)
Speed correction and time lapse compensation
Extraction of audio track for separate analysis
Decoding proprietary digital video from mewer DVT CCTV systems
Magnify video to full screeen, or portion , giving picture in picture
Reverse projection and superimpostion for height analysis
Onscreen text and titles
Technical metering of picture / signal elements
Archiving of material and documentation
Exchange of electronic files with clients worldwide via the internet using industry standard 128 bit encryption
