Listen to this! Klevgrand has released the vocal synthesizer Pipa, which generates incredibly realistic voice. The Swedish company Klevgrand has introduced a new plug-in – the Klevgrand Pipa vocal synthesizer. The instrument works without the use of samples, relying on a mixture of wavetable and granular synthesis.
Synthesized virtual voices often sound too strange: they can be used in sound design, but it is rather difficult to find a use for them in musical projects. Nevertheless, the Swedish Klevgrand managed to create a truly live and musical instrument. Listen for yourself, this is wonderful
As the developers note, the instrument works at the junction of table-wave and granular sound synthesis. The signal generated by Pipa continuously transforms formants, changes the dynamics and pitch of sounds. Although the synthesizer trailer appears to generate exclusively female voices, Klevgrand notes that Pipa is capable of producing sounds reminiscent of both male and female voices of any timbre.
The generated sounds are created from wave tables extracted from vocal samples. Thanks to this approach, when reproducing sound, Pipa constantly changes the formants, dynamics and pitch of the signal, and, as a result, generates realistic-sounding vocals. Not without a fly in the ointment: realism requires significant computing power, so Pipa is quite hungry for processor resources.
In the settings section, the parameters of the signal envelopes and the operation of the low-frequency oscillators are available. You can control the settings using MIDI commands. Additionally, the synthesizer is equipped with a Legato mode, in which the synthesizer glides smoothly between sounds. The list of parameters is completed by the ability to distribute the voice over the panorama and stereo image, as well as a number of settings for the reverb effect.
Despite the expressive video, Klevgrand Pipa is unable to generate words or speech phrases. The maximum available is melodies and chants, atmospheric vocal textures. The developers note that the published trailer shows everything that the synthesizer is capable of, but it will not be easy to achieve such a level of performance – you will have to tinker a lot with the settings and the synthesizer part.
