High pitch sound from computer
The best way to avoid this is to use interfaces that have isolated DACs and ADCs (should be listed as a feature) that are given a solid, constant reference level to work from independent of the power variations occurring within the rest of the hardware. You get the same thing on a lot of computer sound cards and you can notice that it changes frequency when things take power in the computer such as intense processing or hard drive operation. I've looked this up many times and haven't found anyone else running into this problem, but I figured I'd give the forums a shot.
HIGH PITCH SOUND FROM COMPUTER PC
This may cause your PC to overheat and thus force your computer to make more noise besides losing some functionality. The most common of these is that there might be some debris on the cooling fins on the fan’s blades. These variations are what you are hearing with that noise. Hi I'm running into a problem where I'll have my computer on while I'm working, and it will randomly emit an unbearably loud and high pitched 'beep' kind of noise. If your laptop’s fan makes a high pitched squeak, then there are numerous possible causes for this. If the internal circuitry of the interface and the actual capture or playback circuitry share a common power supply, the operation of the electronics itself cause a distortion to the power being supplied to the capture or playback circuits.Ĭapture and output both rely on a fixed reference level and if this level is not constant, it introduces variations in the actual signal produced. That is the result of bad isolation of either the DAC or the ADC. High-pitched whining is a common problem across many USB devices but there don't seem to be any answers other than "ground loop." It isn't a ground loop. I've tried putting a powered USB hub between it and the computer and that didn't help.
HIGH PITCH SOUND FROM COMPUTER PRO
It happens on my mac pro when it is running from battery or when plugged in, on a 2006 original Mac Pro, and on my AMD-based desktop, always exactly the same noise, same pitch. This happens when recording with things plugged in and with nothing plugged in with all possible configurations of the box (phantom power, monitoring, gain, line level, etc.) All XJ Non-modified/stock questions go here - High pitch noise from computer - I am getting a really high pitched continuous noise. In fact, most components in a computer produce a sound but it’s usually just too quiet for most to hear. That high-pitched noise is in common between many brands of audio interfaces, as you can hear recordings on Google. This high-pitched whining noise isn’t always heard by everyone in the same way since the frequency varies and not everyone can hear the same frequencies. I can't figure out which component in the power supply makes that sound, so that I can replace it. I opened it and noticed that it makes a high pitch sound when turned on.
I have an M-Audio M-Track, a $100 USB-based audio interface.Īcross all 3 computers I have tried it on, there is a high-pitched whine around 1kHz, similar to the one here: My PC's ATX power supply stopped working. I've yet to find a definitive answer to this, but Google shows hundreds of people asking questions.
