compressor/limiter designs. This application note describes in detail the circuitry for two basic com-pressor/limiter designs using these devices. The first design is an above-threshold, hard-knee compressor with variable ratio, thresh-old and gain controls. The second design adds a soft-knee threshold. Suggestions for alignment are
14 lis 2011 · This paper explores several aspects of multistage compression systems including economics, equipment temperature limitations, and process temperature limitations. New heuristics are presented that give either the economic optimum or the temperature-limited number of stages as a function of the overall compression ratio.
The schematic shown in Figure 1 is a basic soft-knee compressor/limiter circuit that can be used as-is or as the basis for a more sophisticated design. The circuit consists of a THAT2180C VCA, a THAT2252 RMS level detector, a few op-amps, and a handful of passive components. An alternative would be to use a single THAT4301 (which comprises the VCA,
This design brief describes in detail the circuitry for two basic compressor/limiter designs using the THAT4305 Analog Engine. The first design is an above-threshold, hard-knee compressor with variable ratio, threshold and gain controls. The second design adds a soft-knee threshold.
The difference between a limiter and a compressor, while one of degree, is clearly audible. Compression alters the loudness relationship between soft and loud elements of a signal more dramatically than does a limiter.
30 kwi 2024 · Compressors and limiters apply gain reduction when the input signal level is above the threshold level, while expanders and gates apply gain reduction when the input signal level is below the threshold level.
A VCA (voltage controlled amplifier/ attenuator) is the heart of any compressor or peak limiter circuit, and there are quite a few different approaches. All available circuits have limitations, and this article looks at the various techniques used.
