Modulation Index provides the professional broadcast industry worldwide with engineering services related to achieving maximum accuracy in the broadcast audio transmission signal path allowing maximum audio fidelity and loudness. High-fidelity Internet streaming, from encoding audio to streaming server setup and configuration, are also provided services.

Modulation Index is headed by Greg J. Ogonowski. Having been involved with the professional broadcast industry for over 30 years, and as co-developer of the Orban Optimod® Digital Series of Broadcast Audio Processing Systems, accurate peak control in the transmission path to achieve maximum loudness and sonic transparency is our expertise. He is also co-developer of the Orban Opticodec-PC File and Streaming Encoders, the first commercially available AAC/aacPlus audio encoders for Internet streaming.

Modulation Index has computer-optimized modifications for several current generation analog FM exciters to improve their accuracy and performance to be competitive with today's tough demands.

Modulation Index also has software to manage Program Associated Data (PAD) for RBDS/RDS, HD-Radio, and Internet streaming.


If competitive broadcast/streaming audio is your concern, nobody understands it better, and nobody has better sonic solutions, than Modulation Index.
