I record at a professional studio, with a range of different mics and processors. My current preferred mic is a Blue Bluebird running through a Joe Meek VC1Q Pre-amp, and treated afterwards with a Fairchild 660 compressor and EQ for a really warm, inviting sound.
Finished files can be sent by Email, DropBox, WeTransfer, or through the post on a USB stick or CD. AIF or WAV files are the standard formats, but MP3 versions are not a problem at all.
As a professional musician and composer, I can also provide music for your production - click on the Music Website link to learn more.
