FAQ
Can you remove background noise?
Yes. I can reduce different types of background noise depending on the recording. The amount of improvement depends on the type and intensity of the noise.
Can you make an unclear voice easier to understand?
Yes, where usable speech information exists in the original recording, I can apply speech enhancement and other processing techniques to improve clarity.
Can you remove echo?
Echo and reverberation can sometimes be reduced. The achievable improvement depends on the characteristics of the original recording.
Can you enhance CCTV audio?
Yes, provided the CCTV footage contains an audio track. I can assess the recording and determine what enhancement may realistically be possible.
Can you recover completely inaudible speech?
No editor can reliably recreate information that was never captured. I will assess the source recording and work with the information that is actually present.
