Have you recorded yourself playing the cornet, or another instrument? If so, you might want us to add a little bit of magical dust on it by providing some processing... basically making it sound even better than it does!
We do this by applying some EQ (particularly if there are any annoying frequencies present!), compression and reverb. We don't use any software for this; it's all "done proper" using hardware processing equipment. It is then digitally recorded to CD, where it will be 'topped-and-tailed', and sent back to you over the internet, as MP3 or WAV... or both if you want!
