Full-featured, professional audio processing software transforms Windows PCs into high-end audio processors.

Based on a powerful processing engine designed by Hans van Zutphen, OmniaSST is the first processor to support the Telos Alliance’s revolutionary Omnia µMPX® codec. Omnia µMPX, a specialized codec purpose-built for FM radio, is able to transport high-quality Multiplexed FM signals over a small 320kbps data pipe. Reduced data requirements mean high-quality multiplexed audio and RDS signals can be directly routed over IP from your processor into a decoder application, opening up tremendous possibilities for efficient MPX audio transport.

OmniaSST audio processing software is the only processor with the 3 Ds for your audio needs: Declipper, Delossifer, and Dehummer. With Declipper, OmniaSST repairs incoming audio, optimizing it before it hits compression, limiting, and final processing stages, Delossifer repairs the sound of lossy compressed audio such as MPEG2/MP3 material. While Dehummer removes unwanted sounds such as 50/60 Hz hum from bad cables. These remarkable pre-processing tools result in clean, loud, and open sound.

Finally, OmniaSST audio processing software includes purpose-built Omnia presets, FM pre-emphasis, stereo and RDS encoding, and shares the same FM reception-improving composite final clipper as found on the Omnia 9SG. Using an i7 class processor, latency can be reduced to as low as 5ms. A streamlined, HTML-5 based GUI means easy, intuitive operation.

  • Low-Latency Performance – Using an i7 class processor,  latency can be reduced to as low as 5ms.

  • The Perfect Declipper – A unique filter, also found in our Omnia.9 and 11 flagship processors. It detects and reconstructs clipping-damaged audio (distortion caused by too-loud input levels and overly aggressive mastering), prevalent in music.

  • Delossifier – Improves the sound of lossy encoded audio, such as MP3- and MPEG2-encoded audio.
  • Dehummer – Removes constant tones such as a 50/60 Hz hum on the fly.
  • Lowpass Filter – The extremely steep phase linear low-pass filter can be used to cut off frequencies that cannot be broadcast, removing unneeded signals from streaming audio, FM and AM transmission.
  • Hiss Reduction Filter – A powerful hiss-reduction filter that tackles hiss while leaving adjacent content alone. Especially useful when playing older songs or other noisy content.

  • Natural Dynamics – Boosts transients. This mainly boosts percussion instruments, adding more dynamics, which gives the rest of the processing chain more to work with.

  • Automatic Gain Control (AGC) – The ITU.1770-based AGC keeps the sound compliant to a defined loudness level.

  • Bass Harmonics – This filter increases the base level without increasing the maximum amplitude of the bass, and adds harmonics that make the bass more audible on speakers with poor bass reproduction.

  • Phase Delay – Purposely adds phase-nonlinearity. Can be used among others to generate a more boomy bass.

  • Bass in Your Face – Intelligently adds missing sub-harmonics.

  • Absolute Highs – Reconstructs missing highs if damaged or removed by low-pass filters.

  • 2-9–Band Multiband Compressor / Limiter, x2 – OmniaSST has two multiband compressors that can be used in series. They have a very natural, pleasant, and non-fatiguing sound. Depending on the content, they move very quickly when they need to and slowly when they can.

  • Phasing Error (AZIMUTH) Correction Filter – Detects and repairs phase-shift errors that are often present on tape recordings and some badly mastered CDs. These phasing errors can make listening very unpleasant, and can also cause severe artefacts when converting sound to mono, encoding it using a lossy codec, or when playing it on a surround system. This filter automatically detects and repairs such errors. For FM transmissions, this can reduce multipath distortion and improve the audio quality when the radio blends to mono.

  • Stereo Booster – Boosts the stereo width. It can be configured to not alter the total sound content.

  • Stereo to Mono Conversion – Converts stereo to mono without removing sounds that normally cancel out during a mono sum. This leaves mono sounding just as full and powerful as the original stereo sound.

  • Distortion Masking Clipper – The same clipper that’s available in the Omnia.9sg. Now with a louder and cleaner “Rules are made to be broken” mode.
