Peak Programme Meters
Peak Programme Meters Audio signals in nature can cover an extremely wide dynamic range extending from, at the quietest level, below the threshold of hearing to, at the loudest level, greatly in excess of the threshold of pain! Broadcasters of course do not attempt to emulate this dynamic range, and for entirely practical reasons a very much reduced dynamic level variation must be transmitted. The Listener, or Viewer, will adjust the volume setting in their own home environment so that the Programme is clearly audible above the domestic background noise which will vary from location to location. Invariably Broadcasters restrict the dynamic level range of the transmitted Programme in order to increase the "impact" of the programme audio over this domestic ambience. The dynamic range is restricted by a combination of close- microphone and electronic compression using "dynamic limiters", and in essence, these techniques make the programme's audio sound louder than it would otherwise be. This compression is usually gross on Pop Music channels where the dynamic range is severely limited and often pretty obvious on Commercials too. Measuring audio levels, in a programme production environment, is more complicated than appears at first glance. Programme Audio is subject to the following:- 1) Wide, though restricted, dynamic range. 2) Wide, though restricted, frequency response. 3) Short duration transients 4) Positive and negative signal excursions are often different by many dB. 5) The degree of audio compression will affect measurements. 6) Stereo Phase considerations. 7) The metering must be clear and unambigous. 8).....and other more subtle effects. The characteristics of the measuring device itself totally weight the achieved measurement. -

Logarithmic VU Meter Driver
Recent Researches in Automatic Control Logarithmic VU Meter Driver POSPISILIK MARTIN, ADAMEK MILAN Faculty of Applied Informatics Tomas Bata University in Zlin Nam. T. G. Masaryka 5555, 760 01 Zlin CZECH REPUBLIC [email protected] Abstract: - This paper deals with a construction and practical testing of a VU meter driver that includes an accurate rectifier and logarithmic driver of a pointer-type gauge. The logarithm is taken from the rectified signal by employing a capacitor discharge voltage curve. In the first step, a simple rectifier and logarithmiser was designed and built in order to proof the theoretical premises. Then, based on the experience with this circuit, the more complex design of the VU meter driver was created. Key-Words: - Audio signal rectifier, VU meter, gauge driver, logarithmiser 1 Introduction 2 Logarithm processing Analog audio signal levels are often expressed in The basic aim was to employ a quite simple method decibels compared to one reference level. Analog of processing a pulse-width modulation by a VU meters are usually equipped with a non-linear comparator-connected operational amplifier. The decibel scale which stem from the definition of a rectified signal is periodically compared to a ratio unit [dB]. In this case only a simple front end reference voltage that can be described by the rectifier is sufficient for a satisfactory level following equation: indication. However, it is more comfortable to take and display directly the logarithm of the voltage level of the signal because then one gain an advance where U0 is the amplitude of the reference voltage of a linear gauge scale. -

Gain Structure - Setting the System Levels
Gain Structure - Setting the System Levels One of the most important things you can do to make an audio system sound good is to set up its gain structure properly. Conversely, improper gain setting throughout the system can really make it sound bad. Gain Structure is the term we use for the collection of various gain adjustments throughout the system – the mic preamp, the fader, the main mix output level, the input gain of a power amplifier or recorder, and so on. Setting all of those gain/level controls to work together properly isn’t difficult, but so often it gets ignored. You may run across the term Gain Staging . That’s the process of setting gains throughout the system to achieve proper gain structure. There are many ways of establishing optimum gain structure. Once you understand what you need to accomplish, gain staging will become second nature when you’re faced with new equipment. To understand gain structure and gain staging, you need to understand a couple of closely related terms which I’ve sprinkled throughout these articles – dynamic range and headroom . Dynamic Range Dynamic range is the ratio, expressed in dB (decibels), of the level of the loudest undistorted signal to that of the quietest audible signal. Dynamic range can apply to a single piece of equipment or to a complete system. For electronic equipment, the maximum output is ultimately determined by its power supply – If the power supply provides ±15 volts to the integrated circuit opamps, the maximum possible peak-to-peak signal voltage is 30 volts. -
