TAP Vibrato

This plugin modulates the pitch of its input signal with a low-frequency sinusoidal signal. It is useful for guitar and synth tracks, and it can also come handy if a strange effect is needed.

General information

Usage tips

The "Frequency" control determines how fast the pitch is modulated up-down. Set the amount of pitch modulation via the "Depth" control. When trying to enhance synth or guitar tracks, use the "Depth" control sparingly: if you set it too high, you can easily get the sound of an old tape deck with a worn-out tape -- of course, that may be just what you want... With an even higher setting, you can get the feel of a strongly pulled-about vibrato bar of an electric guitar. Hint: create vibrato simulations with the power of Ardour automation editing.

At small depth settings (between 0.5% and 1.5%) and a frequency setting between 5 and 15 Hz, mixing the pitch-modulated signal with the original sound yields a chorus-like effect. The "Dry Level" and "Wet Level" controls exist to support this kind of setup. By default, the dry signal is muted, and the wet signal is output with 0 dB, so you won't need to touch these contols if you don't want to create such a mix.

Summary of user controls

Notes

Resampling is done using linear interpolation. Higher orders would probably yield somewhat better quality (at least in theory), but since no side-effects were heard (apart from the fact that this plugin is a side-effect in itself), that was considered to be a waste of CPU.
