1  Our advanced technology has improved during 40 years, the sound of the Radio stations in 50 countries  Use arrow keys to change slides    change slides Audio Processors for AM & FM

2 We started at 1968 the manufacture of audio processors for radio stations… Our competition at 1968 were CBS Labs, RCA, Gates and Telefunken…. …All those companies disappears from the processor market… Now Solidyne with 40 years of continuous innovations is the world oldest company; then, only Solidyne is able to offer your the largest experience in this field !

3 Our superior experience is a guarantee of the audio quality of our processors  The design and manufacture of audio processors is an Art and a Science… It is like manufacturing violins…  We spend many years of research and publication of many scientific papers. Our 40 years of full commitment will help your radio to sound better and to improve your coverage  Now we will show you a brief description of the psychoacoustics involved in audio processing technology

4 The psychoacoustic process starts at the internal ear Nervous fibers goes to brain

5 The basilar membrane is located at the internal ear The basilar membrane of 30 mm length, has many vibration cilias connected to about nervous fibers

6 The standing acoustic waves produces excitation of the cilias. The movement activates the nervous fibers  Each audio tone produces excitation according your audio frequency  According to the audio frequency, different zones will be activated 2 pure tones excitation 7 simultaneous tones

7 In order to get the auditory sensation of strength and loudness, it is necessary the excitation of almost all the basilar membrane

8 Unprocessed music and voice usually only gives excitation to a couple of bands Position occupied at Basilar membrane f1 f2

9 Multiband audio processors elevates the sound energy of all audio bands by individual compression and digital limiting 160-2khz 2k- 6 khz 6k–15 khz Audio Input Band Filters Audio compression Hz SUM OUT Limiter

10 After audio processing all audio bands has high excitation at the Basilar membrane Position at basilar membrane High basilar membrane excitation = loudness sensation

11 Masking of audio bands  Masking is the property of the ear to avoid the hearing of some tones due the presence of other tones at high level  This property of the ear allows the processor designers to use high compression ratios without loss of the audio quality  If you are interested in learning more, we recommend you the AES paper: “Multiband Audio Processing and Its Influence on the Coverage Area of FM Stereo Transmission”, by O.Bonello, Journal of the Audio Engineering Society, New York, March, 2007 ( Masking of audio due to 3 pure tones of 0,25, 1 & 4 Khz

12 A good audio processor improves the sensation of audio quality  We spend thousand of hours during 40 years, hearing on air AM & FM transmissions in order to get the best sound quality

13 A good audio processor increases the coverage area of AM & FM Radio Stations  Audio processing increases the energy of the audio signal  The coverage area will increase between 50 to 80 %  Not convinced ? Please read a scientific demonstration at:  O.Bonello, “New Improvements in… “ JAES vol 24 Journal of the Audio Engineering Society (USA), June 1976 (  O.Bonello, “Multiband Audio Processing…”, Journal of the Audio Engineering Society, New York, March, 2007 (
