I chose Alfredo to support me with the recording and editing of my audiobook, On Purpose, after he came highly recommended. As well as high spec recording equipment, Alfredo brought incredible knowledge, expertise and patience to the project ensuring that I finished with an exceptional product. If you’re looking for a sound engineer that you can trust then look no further.

You worked tremendously hard on this film, from formulating initial ideas to manifesting them through experimental sounds. The sound on the film was a very hard job and the results truly exceed all expectations. Without your creativity and patience, this film wouldn’t have been possible.

Film Director & Writer

You have done a great job. The recording is perfect and I am so happy as the editor because a really good and serious sound person is very hard to come by.
