SimplyLowPass
Read full descriptionHide full description
A simple but fast low-pass filter with control over cutoff frequency and resonance factor. The filter exists in an AUv3 app extension so it is available for use in any host app that supports AudioUnit components such as AUM or Cubasis or GarageBand. This app is just a delivery mechanism for the AUv3 app extension and a demo of how it works.
shortReverse II
Read full descriptionHide full description
Concept: “shortReverse II” is the advanced version of “shortReverse” which was previously released. The second has the same functionality as the first but resolves professional needs, that is, the problem of restricted buffer size (2^N). Now the user can freely adjust the buffer size from 256 to 65536 (in 1 sample unit). Usage: The user can reverse an incoming audio signal in real-time only while pushing the button. "buffer size" slider is text-editable by clicking. Note: Button automation in DAW is not supported. System Requirements: AUv3 host stereo output: just plug headphone/mic or audio interface.
