Trautonium Formant Filter

A-104

1. Introduction

Module

A-104

is a replica of the

Formant Filter

of the

“Mixtur Trautonium” by Oskar Sala. It is made of

four parallel resonance filters with common input

and output (see fig. 1 on page 3). Each filter can be

switched to low pass or band pass or off. Frequency,

resonance, mode

(band/low/off) and

level

are con-

trolled for each filter separately by hand (no voltage

control !). The frequency range for each filter is about

50Hz...5kHz.

The input level for all filters is controlled by an at-

tenuator. The filter audio inputs are very sensitive so

that distortion may intentionally be used to create new

sounds - if desired.

The A-104 is a versatile module for sound modifica-

tion. In the first place it is used for reproduction of

resonances (e.g. the vocal-like effects known from

the Trautonium). In combination with the

subharmo-

nic generator A-113 one obtains the complete replica

of the Trautonium sound generation.

More detailed information about the Trautonium can
