Hello there :) My name is Stefan. I'm a professional recording engineer, composer and sound designer at Illusia Productions. We have over 15 years of experience in the audio business and we can deliver high quality music, sound effects and voice overs as well as audio services like mixing, mastering and audio restoration.
We have done many audio restoration jobs already here on Freelancer.com and many more on other platforms and through our website: [login to view URL]
Please send me a snipped of the audio material, so I can see what can be done to it, because it always depends on the sort of noise if anything is doable and if, how much improvement can be done.
Long term isn't a problem either. :-)
If you have any questions, feel free to contact me. :)
Best regards,
Stefan
PS: Ich habe gerade erst gesehen, dass du aus Deutschland kommst, dann können wir auch gerne deutsch sprechen :-) Bin nur ein wenig eingerostet, lebe seit Jahren englisch sprachig. ;-)
