The analyzer section contains 20 specially designed l'ilters, accurately tuned and trinrmed for center frequency, bandr,v¡dlth, gain and Flatness. Center frequencies have epproxímately li4 octave spacing, the fi ìter at the low end of the audio range being a ìovr pass fi ì ter, and the fi I ter at the high end being a high pass filter. Filters in betr¡¡een are bandpass filters. This design provides a precise anaìysis of the audio spectrum between approximately 30 Hz and l6 kHz. Within a dynamic range of 60 dB, trequencies in a complex audio s ignaì can be detected and converted int<¡ controì vol tages, which are fed to a rovr of 20 LEDs, dísplaying the energy in each frequency band. The analyzer is located in the upper part of Syntovox 221, constructed on ê seDarate Drinted circuít board. The 20 control vol tðqe outputs of the analyzer are directed to a 20x20 matrix svsleil and to the muìtiwav connector at the back paneì of Syntovox 221. These outputs have a range of 0...5V and can be used to conr-rol external devices. For computer appl ications a 20 channel mul tiolexed AD converter shôuld be used to be able to store audio anal'¡ses. SYNTHES I ZER The 20-channel synthesizer is also composed of one lcw pass and identical to the one highpass filter and 18 band pass filters, anaìyzer. The synthesis fílter bank has one audio input and one audio output. Each of.the 20 f ílters is foìlov¡ed by a modulator with a control voltage input 'nrhose sensitivity can be adjusted by means of the potentiometers in the bottom row of Syntovox 221. These aItenuators are numbered 1...20 and are routed to the correspondinq matrix columns and the control vol tage inputs at the back panel mul t iv/ay connector. The amount of contrcl vol tage fed [o the synthesizer rnodulators can be monitored by means of ihe LEDs near the control knobs. MATR I X The control connections betr^reen analyzer and synllresizer are mad¡ via the 20 x 20 matrix system. Any controì voìtage output can l-.e patched to any control vol tage input, Timbre can be chanEed easì ì ¡ by shif tinq all anaìysis information up or dovrn the synthesis f ilter bank. In the norm¿l mode al I anaìyzer control outputs are connected to corresponding synthesizer controì inputs with the rnatrix pins in the d iago:ra I pos it ion f ron Ihe L]pper lef E corner to the bottom right corner. A signal appì ied to the audio input ofl the synthesizer wi I I be shaped according to the signal which is being exarnined in ':.he analyzer section. 221.)l /Ì'il It is uery important to understand that in this z.espect the uoeoder acts as a moduLatoz, alñch úntposes the characteristics of one audic s')gnaL upon another au.d'Lo sígnaL. So, ii speech is applied to the anaLyzer input, the inteLLngibiLity chanacteristias are imposecl upon únA other signaL, fed ínto the synthesizer, prouidecl that sigrtaL L:loes conbain a reasonable amount of harmon't cs - it uiLL not uork on a sine uaue! CONTROL SYSTEM Since speech is a composite oF voiced sounds (4,E, l,O,U, etc.), and unvoiced sounds (sibílants, K,P,T, etc.), a detection system to d iscriminate these phenomena is necessary. l./hen Syntovox 221 is used for speech synthesis Èhis voiced/unvoiced detector feeds noise to the synthesis fi I ter bank when a sibi lant is detected, and s imu I taneous I y the replacement sound at the synthes i zer i nput ís cut of t. Voiced and unvoiced decisions can be used for Eriggering external devices, and it is also pos5ible to control the operation,of the voiced/unvoiced deEector external ly. In Ehat case the lNHlBlT control should be used to bìock the internal circuit which normaì ly drives the detector. Control inputs and outputs are avai lable at the mu I t ir^¿ay connec cor a t the back oane I . INTERNAL PULSE IiI + Çr rt GENERATOR Syntovox 221 is equipp.ed with a pulse generator for simple but effectíve speech synthe.sis. This pulse generator is voltage control ìed andcan be modulated external ly, oF with the bui lt-in low frequency control osci I lator and random generator. The low Frequency control osci I lator can be used to introduce a vibrato whose speed and depth can be control I ed. The random generator has two outputs to control the pul se frequency. 0ne of the outputs generates a stepl íke change of frequency each time a short interval in the speech signal is detected; (Sffe¡. A very low freguency random signal is avai lable to create a continuously changing pitch; (vlr). EXTERNAL SOUND SOURCIS External sound sources can be modulated by the analyzer input s ígnal as iveì I . Both UNVOICED and V0 | CED paths i n Syntovox 221 have a separðte input (B and C respec t i ve I y) for app ì y i ng sound material to the synthesis f il ter bank, other than the internal ly generð ted pu ì se and no i se. 221 .D2 /t47- FILL-IN CONTROL control was designed for special speech synthesis purposes. When a replacement sound is to be modulated with speech, for instance, â signal only wí | ì appear at the output of Syntovox 221 when there i s i nformat ion from the ana I ys i s fi lter bank. The FILL-lN control is meant ro fi I ì rhe gaps between spoken words by automaticaìly tading-in the replacement sound, so that the origín and character of the replacemenl soundrvill not be obscured. lmmediateìy this replacement sound wi I I be faded out when speech is appl ied to the analyzerThe amount oF FILL-lN can be controlled with a potentiometer. The FILL-lN CLEANFIED Next to the analyzer input attenuator two controls labeììed SYNTH and CLEANFEED are s i tuated The CLEANFEED control is a direct feed from (speech) input to output, and the sYNTH controì feeds the i nput s igna I d i rectìy to the synthesis fi lter bank. This faci I ity offers very ínteresting possibi I ities when instead of speech the signar of a music synthesizer is processed via Ehe analyzer input. By exclusively Feeding noise to both voiced and unvoicecr sections, the s-ound of the music synthesizer will be enriched with additional harmonics, selectively f iltered out of pink _ noise.

EXAMPLES/MATR I X OPERATI ON In this section only a few of the numerous possibil ¡ties of programming the matrix can be given. The small knobs in the bottom röw, numbered 1...20 are also important in al I appì ications, since they can attenuate the control voltages fed to the synthesizer inputs. Changing these control voltages has the effect of processing the sound through a channel equalizer, which can be used very effectively in almost all applications. The way first example given below states the right and the wrong to use the matrix. PINS SHOULD NEVER BE PUT lNTO THE SAME \./ILL CONNECT OUTPUTS OF THE ANALYZER P0lNT.
