9/8/2023 0 Comments Speaker clipping detectorI didn't bother because my application was driving a full-range loudspeaker, plus most music has the bulk of its energy at LF anyway. But do bear in mind that this circuit only detects voltage clipping. Current clipping will be missed, but sounds equally bad. Generally no need to get involve with high supply rails.PEQ in Roon's DSP leads to clipping on some bass heavy tracksįor that reason, you might prefer the SIM project: I've also done this (different version, again before I'd seen Rod's), and in most applications it's a better bet. Roon clamps the samples when they exceed the bounds, so there is no concern about damage. The clipping indicator is informing you that a sample value was limited, not warning that a dangerous sample got through.Īll clipping introduces distortion. Soft-clipping creates distortion that is less offensive to the ear, but it is still undesirable. Soft clippers make more sense in systems where you can’t anticipate signal levels in advance. That is not the case in playback software where a small, fixed amount of headroom suffices to totally remove the problem. I’ve just bought a Ps Audio DSJ which outputs a low level signal in the RCA connections, considering that it’s connected to a valve amplifier. So, even with the clipping light blinking, i should not be worried about damage my amplier/speaker, correct? Just to be sure: the clipping warning isn’t about the possibility to damage the amplifier/speakers, but only to warning about possible problems in the sound quality, right? Therefore, i thought about using roon to boost +3db on the signal. That’s the point, as the clipping indicator is so sensitive, it’s hard to know what’s really going to harm the system. Roon’s pipeline information and peak indicator are about informing the user about the audio quality of the digital processing pipeline which on many system can be quite opaque. The peak indicator is not too sensitive and I believe it represents a modern industry standard behavior of such peak/over indicators (also known as ‘true peak’). It is not an indicator of amp clipping of course as it cant know what the output level of the amp is. I think you need to have a look at the manual of your DAC: The problem with a clipped source is if you already have clipping, then as you turn the amp up, you may not notice the onset of clipping (as it is already there) and so you get no audible warning that you are exceeding the amps capability.Ī clipped single has more RMS energy than typical music program material, and so an amp’s max RMS output level can be higher than RMS rated which makes it more likely that speaker coils overheat (depending on speaker rating). Output rating appears to be as follows: Output level (Low) This part of the peak level display is called the clipping indicator. Note: Its not an issue if individual channel strips show evidence of clipping.
