![]() If you want to see the numbers, you need to expand the tracks horizontally. I love it that Ableton added this function, but it's still not easy to read numbers for the average level. In Live, the light-green bars on top show Peak, and the dark green bars in the middle show RMS. You need a VU meter plugin because the Ableton meters don't show RMS / VU level very clearly. And music has to appeal to the ear, right? You can't really use Peak meters to compare the loudness of two sounds as they appear to our sense of hearing. VU meters react more slowly, like our ears, which gives you a realistic picture of the loudness that a sound is pushing. But if you set both your bassline and drum loop to -5db using RMS/ VU meters, they will sound balanced to the ear. Drums are a sound that peaks with very short, loud transient spikes far higher than the actual loudness of the whole kit - but a bassline has low, fat transients that peak very close to its average level.Įnd result, a bassline will sound way louder than drums when you measure them with a Peak meter. If you have a bassline that peaks at -5dB, and a drum loop that also peaks at -5dB, it does not mean they will sound balanced next to each other. ![]() (A peak meter doesn't do this very well.) Use RMS, or VU meters, to compare two sounds to each other and get a realistic picture of how loud they are. You need them to compare how much space a sound takes in the mix. VU meters (RMS) show you how loud a sound feels in real life. You already get this concept, it's obvious like a stop sign. Peak meters are simple to use, just keep the meter in the green and bring down the volume if it turns red. This is really important because digital audio has a hard limit and beyond that you get a particularly awful type of distortion. Peak meters tell you how to avoid digital distortion. Why do you need them both? Because they do two different things. RMS means average, Peak means Peak and you need them both. It was originally a mathematical average taken from the square root of the signal voltage over time. However when tracking less dynamic input sources, the release time acts more as a smoothing value for the CV output.RMS means "Root-Mean-Square". ![]() When tracking percussive audio signals this will be very similar to a traditional envelope’s release stage. Release- Adjusts the amount of time it takes for the CV output to decrease in voltage as the input signal’s amplitude decreases. ![]() Input Level- This VU meter displays the amplitude of the incoming audio signal after being scaled by the Gain knob.Įnv Out- This VU meter displays the CV output signal. Gain- Scales the amplitude of the input signal from 0% to 200%. In jack- Input jack for the audio signal that will be converted to a CV output. A drum loop, for example, could be used to modulate the cutoff frequency of a filter, the pitch or pulse-width of an oscillator, or the rate of a Super LFO! Input, Output, and Controls This is a great tool for creating dynamic CV signals that can be used to modulate just about anything in Voltage Modular. The module has VU meters to monitor the input and output signals as well as an adjustable input gain and envelope release time. The Cherry Audio Envelope Follower converts the amplitude of an incoming audio signal into a control voltage (CV) output. ![]()
