Lime Street Acoustics

audio restoration and forensics




Audio is a very fickle thing.
Set up the mic, hit record and then………stuff happens.

In the century since audio recording was invented audio disasters have conspired to make it difficult for all those who wish to use archive or freshly recorded audio.


Sometimes we have less control of the audio as its part of the video. We concentrate on the shot and hope the sound is ok. Once it was a dedicated cameraman and soundman. Now it's Go Pros, DSLRs and mobile phones with high quality picture and every chance of the audio going wrong.

Audio post budgets have shrunk again and again and frequently the chances of getting 100% quality audio are not a certainty. Professional audio recordists, if they are hired, are put under pressure. Stuff happens, and the professionals use all their expertise to make sure they get a good take. Sometimes there is only one chance and there is the hope problems can be sorted out during post production. Sometimes the best visual has unusable audio and the director has to choose second best.

Music recording is normally in a more certain environment but gremlins still creep in. Mic stand bumps, small room honk, creaky pianos and chairs, amps that won't behave are just the start of a signal chain that may be not right but the performance is. Cock ups such as double eq or compression are notoriously difficult to reverse, we have no problems undoing. We can iron out the worst wrinkles in live performances to give premastered tracks ready for a mix. We specialise in rebalancing elements in a stereo or mono mix where there is no original multitrack.

Similarly you may have a special occasion such as a wedding and the special moments are destroyed by camera clicks, mobile phones or other intrusions.

Audio rescue at Lime Street Acoustics means a chance at not accepting second best. Audio rescue, restoration and forensics is our business with 45 years of experience covering from wax, vinyl and tape right up to all modern media formats. We have built up the experience of all the old analogue cleanup methods and also utilise the latest digital source separation techniques to carve out something usable from the worst of audio nightmares.

Mics that get bumped, covered up, rustled, battery going flat, not connected properly, too far away, grossly overloaded, along with unwanted traffic, jets, engines, electrical interference, crowds, sirens, mobile phones, GSM interference, cameras clicking we like to rescue the desired audio and leave all the bad stuff in the bin. 

This same approach is also taken for recovering audio from the past, old tapes, shellac or vinyl discs in order to return it to its pristine state.

What type of audio material can we clean-up?
