Leading Aphex Technology The Compellor circuits are totally unique. By throwing away all conventional design ideas, we created audio processing with unprecedented sound transparency, yet is exceedingly effective at controlling levels. Because our designs are patented, no other company has been able to match the performance. Algorithms like our exclusive “DVG”, “DRC”, and “FDL” have yet to find any rivals. Unmatched Reliability Aphex engineering and manufacturing produces products that last and last without need for repairs or calibration. Some Compellors have literally been in 24-hour use in the same rack for a decade or longer! When you specify a Compellor, you know it will do its job flawlessly and give you peace of mind. Digital Advancements The first Compellor was introduced in 1983 as an analog product. Because of their advanced technology, most of those older units are still in regular use. Since that time, newer models have been produced, still in analog form. Digital technology of today promises many improvements in user interfaces, and sometimes in sound quality, but not in audio processing algorithms. No digital processor can match an analog Compellor for sound quality and effeciveness. Nevertheless, many of today’s systems need a Compellor that can interface to digital audio. With the model 320D, Aphex brings you just that. You get all the advantages of the analog processor with AES3 connectivity. Compression - Leveling - Limiting: A Very Brief Tutorial Two properties of audio that can cause problems are the average level (the “loudness”), and unpredictable peaks that can clip. The Compellor handles both problems for you, fitting the sound into an ideal sound envelope package. The Compellor’s “Frequency Discriminate Leveler (FDL)” section with the “Dynamic Verification Gate (DVG)” and the “Silence Gate (SG)” slowly corrects the volume level of an audio stream with very complex algorithms that hide it’s work. It works differently at different frequencies, for example. It locks up when the sound stops, and resumes instantly when sound reappears. When you listen, you know the levels are made more even, but you don’t perceive the levels are shifting. The Compellor’s Variable Slope Compressor with the “Dynamic Recovery Computer” and the “DVG” work on top of the leveling platform to add adaptable compression that helps match the texture of changing audio sources. Again, you don’t hear “pumping” or other compressor artifacts. Just very natural sound that is evenly consistent in loudness. The Compellor’s limiter acts on peaks that shoot beyond typical audio crest factors. Extremely peaky sounds will be brought into an envelope that is easy to handle by any analog or digital recording or transportation medium including digital codecs. Typical Uses Broadcast pre-processing, MP3 encoding, Recording, Installed and Mobile Sound, DAW Input, Mastering, Satellite Uplinks, Home Stereo, Ham Radio, Background Music, Tape Duplication, Cable TV.
