The de-esser is set to precisely remove the whistle.
The audio would benefit from a second pass with the de-esser set to a broader range of frequencies.
Anyone ever heard a whistling sound while roaming the open world? I've had this happen a few times. Sounds like a bottle rocket or something along those lines. I just have no idea what in the game could cause that sound.
Hi! Does anyone know where I might be able to find a MIDI sound/sample that sounds like a whistle being blown? Not a human whistling, but like a band or drill whistle. The kind used in drill music? Googling this continues to turn up white papers on corporate whistleblowing and I can't get to what I'm looking for! any help would be much appreciated!
Seems most likely a sound like that would either come from the rear brakes or from the booster. Suggest to focus on determining if the sound is coming from the front of the car (where the booster it located), or from the rear, (where the brakes are located).
I've read some of the posts regarding the whistle motors that got me to the point where I've identified the relay as the reason the motor wasn't running. Many thanks to the forum members. However, even when the motor runs, there is no whistle sound. Can anyone point me in the right direction on that one?
I assume the fan blades are turning and the air hole on the whistle chamber is not blocked. If so, vary the track voltage to the motor. If the track voltage is too low, the whistle will not sound. Likewise, I have at least on tender whistle that will not sound if the voltage is too high.
You can test the whistle chambers by blowing through the botton of the housing with no power to the motor. You should get a good two-tone whistle doing this, keep the exhaust holes clear(fingers off!) & unblocked.
The code reads in a file, goes window-wise over it and does an FFT on each window. For each FFT it looks for the maximum coefficient and outputs the corresponding frequency. This does work very well for clean signals like a sine wave, but for an actual whistle sound you probably have to add more. I've tested with a few files with whistling I created myself (using the integrated mic of my laptop computer), the code does get the idea of what's going on, but in order to get actual notes more needs to be done.
2) To match the frequencies to actual notes, you could use an array containing the frequencies (like 440 Hz for a') and then look for the frequency that's closest to the one that has been identified. However, if the whistling is off standard tuning, this won't work any more. Given that the whistling is still correct but only tuned differently (like a guitar or other musical instrument can be tuned differently and still sound "good", as long as the tuning is done consistently for all strings), you could still find notes by looking at the ratios of the identified frequencies. You can read _%28music%29 as a starting point on that. This is also interesting: _key_frequencies
3) Moreover it might be interesting to detect the points in time when each individual tone starts and stops. This could be added as a pre-processing step. You could do an FFT for each individual note then. However, if the whistler doesn't stop but just bends between notes, this would not be that easy.
My A7Rii has the latest software and it has less than 11 thousand shots. I took it with me to a trip in the highlands and it suddenly started a loud whistle sound. I got confused. I did not know where that sound came from. It came from the camera! I turned it off and the whistle went away. I was wondering if you're familiar with this problem
No, it's handheld. I was shooting yesterday in town and it started doing it again! It's like a whistle with a rattle... I have already taken it to a Sony repair shop and they couldn't find the problem. I think it is because very few people have this camera in Peru so technicians are not real experts. They clean up the sensor, reinstalled the firmware and that's it. After a while, it's back doing it.
The LowePro PhotoSport Outdoor is a camera pack for photographers who also need a well-designed daypack for hiking and other outdoor use. If that sounds like you, the PhotoSport Outdoor may be a great choice, but as with any hybrid product, there are a few tradeoffs.
We ran into our first problem with a whistle sound from 40mph > 70+mph. Its still noticeable with the windows down. its for sure going to be put on the list to have the dealer look at it when we have other problems since its minor.
My R (Mk7.5 2017) has developed a whistle on full throttle. I've attached link ( =0 ) to a very short and small (3Mb) video with a full throttle run top from 2nd gear, up through 3rd gear just to demonstrate the issue. I had the car in ECO exhaust mode so there would be minimum masking of the 'sound'.
I know I'm waking this thread from the dead, but I've just had this happen to my car today! I was driving down the street at 5mph, came to a stop, and the next time I took off heard a weird whistling noise. I was immediately terrified, because this is how the turbo sounded on an old diesel focus I had right before it went out. Now whenever I get higher in the RPMs and engine load, there's a very distinct "Whirrreeeeeeeee" noise. OP, did you ever figure this our?!
It could well be fans. On well used systems, I have been known to pull the silver coloured tape covering the central axis and bearing and squirt a little oil in to make them run smoother. As to it being the switched mode power supply, that is also possible - could be internal fan or even magnetostriction in the inductors. The frequency of the switching should be higher than the human ear can detect and you should not detect it although sometimes that is possible with some PSUs and some sensitive people. Inside the PSU the components have a squirt of hard material to stop any vibration and sound generation. As you are doing, the best course of action is to try another PSU.
Be careful with adaptors that reduce the amount of "prongs" since they remove the earth connection. That can remove mains hum by removing an earth loop but are not really safe and should be used with extreme care and only as an experiment. I don't think that the high pitched sound is caused by an earth loop.
