The resulting signal contains a strong DC offset.
If possible, the convolution sample used should not contain any DC offset. If it exists, you
can remove it with the corresponding "Remove DC offset (view page 531)" function in the
"Offline effects" menu.
Heavy hard disk activity, or an error message concerning insufficient memory
was received.
The algorithm needs lots of storage space, especially with long impulse response patterns.
All background processes should be terminated and all RAM wave projects that are not
needed should be closed.
Vocoder
The vocoder sends a carrier signal (for example, a string instrument or a synth chord)
through a modulator (for example, speech or song, or even drum loops) to alter it in such a
way as to make it seem as if the string instrument is speaking or singing.
This is done by transmitting the modulator's frequency characteristics to the carrier. The
modulator signal is divided into a number of frequency bands and apportioned positions at
regular intervals in the respective frequency bands. These measurements control a filter for
the carrier that correspond to the same frequency bands.
Strictly speaking, a vocoder has two inputs and an output. Since Samplitude effects
normally have only one input, the carrier signal will be extracted within the effect, and will
be smoothly mixable with the white noise and any wave file. You can also invert the carrier
and modulator in order to use the vocoder input as the carrier.
The vocoder also offers a real-time FFT filter for editing the vocoder signal.
Filter curves
The yellow line corresponds to the frequency progression of the modulator, while the light
blue line represents the carrier signal. The red line is a freely-adjustable FFT filter. The
