FpDTG.jpg' alt='Speed Meter Pro License Key' title='Speed Meter Pro License Key' />Consumer audio equipment often features VU meters, both for utilitarian purposes e. The original VU meter is a passive electromechanical device, namely a 2. A DC dArsonval movement ammeter fed from a full wave copper oxide rectifier mounted within the meter case. The mass of the needle causes a relatively slow response, which in effect integrates the signal, with a rise time of 3. Unity Pro M Download Crack more. VU is equal to 4 d. Bu, or 1. 2. 28 volts. RMS, a power of about 2. VU is often referred to as 0 d. B. 3 The meter was designed not to measure the signal, but to let users aim the signal level to a target level of 0 VU sometimes labelled 1. In effect, the scale ranges from 2. VU to 3 VU, with 3 VU right in the middle. Purely electronic devices may emulate the response of the needle they are VU meters in as much as they respect the standard. The VU meter intentionally slows measurement, averaging out peaks and troughs of short duration, and reflects more the perceived loudness of the material than the more modern and initially more expensive PPM meters. NKghfBuS4/hqdefault.jpg' alt='Speed Meter Pro License Key' title='Speed Meter Pro License Key' />For this reason many audio practitioners prefer it to its alternatives, though the meter indication does not reflect some of the key features of the signal, most notably its peak level, which in many cases, must not pass a defined limit. In the broadcast industry, loudness monitoring was standardized only recently. The original designers of the VU meter were tasked with finding a way to measure complex audio signals with a simple technology. Since a VU meter is a mechanical device it can never reflect the instantaneous signal peaks of complex audio signals. The designers of the VU meter therefore took a different approach. They created a meter that did NOT measure peaks but simply inferred them. A real VU meter has a very specific ballistic characteristic. This means it responds to changing audio signals at a very precise speed, rising from no signal to 9. VU when a 1 k. Hz sine wave tone is applied for 3. When using a VU meter, the audio system is calibrated with a sine wave tone at a reference level for the system. At the reference level, the VU meter shows 0 for a sine wave tone, but the engineer must know that, with music or speech, to always infer that peak levels are always between 6d. B to 1. 0d. B higher than the reference level. The usefulness of the VU meter comes from the fact that for most types of audio sources the system engineer can count on these peaks being within this range and can design the audio system with confidence. Good engineering practice is to always build in a little extra headroom as it is called, to cover the strange conditions where an audio signal might exceed normal peak levels or the equipment operator fails to adjust the levels correctly. Typically the levels considered when designing systems using a VU meter are Reference Level typically 4d. Bu, valid with tones onlyStandard Output Level 1. B above Reference, typical peak levelsClip Level 6d. B above Standard Output Level, headroom to allow for unusual conditions45Standard characteristicseditThe behaviour of VU meters is defined in ANSI C1. Superjpg 5.2 Download there. British Standard BS 6. IEC 6. 02. 68 1. Reference leveleditVU defined The reading of the volume indicator shall be 0 VU when it is connected to an AC voltage equal to 1. Volts RMS across a 6. Bu at 1. 00. 0 cycles per second. Note The reference above is generally true now and was always true in the recording industry. However in some North American broadcast installations up until late in the 2. Reference level 0. VU was 8d. Bm at large studio installations and some used 1. CFRB Toronto and CFPL London Canada This was yet another standard established in the early years of audio and the VU meter was altered by changing the series resistors to adjust its sensitivity. This had no effect on the ballistics. Rise timeedit. The response of a VU meter black line compared to instantaneous input level grey area of a drum beat. Level is in d. B and time is in seconds. The rise time, defined as the time it takes for the needle to reach 9. VU when the VU meter is submitted to a signal that steps from 0 to a level that reads 0 VU, is 3. The overshoot must be within 1 to 1. The fall time is the same as the rise time, 3. Frequency responseeditThe level specification is meant at 1. Hz. The reading should not depart from the reading at 1. Hz by more than 0. B from 3. 5 Hz to 1. Hz or more than 0. B between 2. 5 Hz and 1. Hz. Note that the specification mentions only sinusoid waveforms. Given the electromechanical principle of the meter, the deviation of the needle is actually approximately proportional to the average of the part of the signal with more than approximately 0. V instantaneously because of the two copper oxide rectifiers always in series, which transfer function curve has a knee around 0. V. Signals generally do not have a sinusoidal waveform by far, even if they all fall within the VU meter bandpass. The reading is the average of the voltage,9 and is not an indication of the power of the signal, which is proportional to the average of the square of the voltage, or the root mean square RMS value. As a conventional VU reading, however, it served its purpose as an indication a of the overall level and dynamics of the signal and b of the proximity to the maximum admitted level, to the operators of recording and broadcasting equipment. Maintenance staff could also use it as a measurement apparatus, to check for losses in transmissions and level alignment, provided that they used exclusively sine waves as test signals.
