Welcome!

Hidetomo Katsura and Rustle Laidman join to bring you the finest quality audio applications.

Our tuners "listen" while you tune and visually guide you through the tuning process. Hands-free operation. Fast, simple & incredibly accurate! Tuners shown from the "Vintage Series" include... Guitar Tuner, Bass Tuner, Chromatic Tuner, Lab Meter and Grand Staff Meter. Vocal Lab is for singers and instrumentalists wishing to improve their intonation.

Visit our web Store to download any of the Tuners you see below. View the User's Manual in our Help department.

NEW! Vocal Lab with scrolling, resizable window is here. (See image below.)

Audo Units (AU) plug-in versions of our products are now available! For host applications that support Cocoa UI AU plug-ins, such as GarageBand, Logic Express, and Logic Pro. Select the "Audio Unit Plug-ins" product category in our web store to download. (Please try the AU products before purchase to make sure they work with your host application.)
