Hi folks, Chris (LinkedinSoundBetter) plus team here. I am an audio engineer with 25+ years of experience, and since 2018 I have been steadily adding machine learning and data science to my toolbox. I specialise in recording & mixing, mastering, audio restoration, and guitar re-amping. About machine learning, I focus on audio data wrangling & augmentation, music information retrieval, sound detection, speech recognition, and speech synthesis. Besides running two record labels (100+ releases), I am also an active musician & producer. As an instructor, I have taught Audio Engineering to hundreds of students (I initiated the opening of SAE Athens in 1998).

So what about the team? It comprises several audio engineers, mainly in Athens and a few worldwide. Each boasts immense talent and expertise in their field, often specialising in specific music genres and audio processing techniques. Together, we can swiftly attend to the most delicate job with absolute professionalism. We will breathe freshness and excitement into your audio and music. Let’s connect!
