I can edit, manipulate, and import licensing-free music and atmosphere tracks into your short film project, as well as compose and record original score music. I can also produce sound effects tracks and foley sounds. I have a collection of "off the rack" sound effects and can also record files on location using high-quality portable digital audio recording equipment.
SMPTE and even 5.1 digital surround-sound are possible at Mitch Amatrudo Voice, Music & Sound.
