Software-based multiband audio processing

Software-based multiband audio processing

The Ecreso FM transmitter range is to benefit from a new digital multiband sound processor, with two levels of processing available. The wide-band version features a gated AGC, an improved FM limiter and an MPX power limiter, while the multiband version offers a full processing chain that also adds stereo enhancement, five-band processing, five-band limiters, HF and final limiters.

The system is hosted within the direct-to-frequency digital modulator of the Ecreso FM transmitter, which Worldcast Systems said ensures that the signal quality is of the highest standard. The signal is processed from audio to RF in a single digital step which leads to a significant increase in quality, said the company.

Gregory Mercier, product manager, Ecreso, said: “Our integrated audio processor requires no additional hardware which means no additional points of failure in the transmitter system.”

The audio processor is supplied with a full set of presets for many different formats and requirements ranging from maximum transparency to high loudness and including several ‘sonic signature’ settings. Control is seamlessly integrated with the web interface of the Ecreso Transmitter.

The new audio processor is available as a software feature on new units and also as an upgrade to the many compact Ecreso FM transmitters in the field.
