Sound Recording

Hi everybody, I know very little about sound recording. My focus is on capturing sounds for surveillance/security use. I thought maybe a high quality sound recorder would be the way to go rather than a security system. That being said, can anyone recommend any equipment? Ideally I need to be able to...

Recording car horn

I was wondering if anyone can provide me with advice with being able to reproduce/record the sounds so I can have proof. My main difficulty is being able to pick up the sound. My recordings are faint and not nearly as loud as it really is. I do not know if the problem can be the microphone, or the r...

Re: Car Horn Masking

There have been postings about how to record it so to turn the perpetrator in to the authorities. I don't know that we ever successfully resolved any of the postings. Can you tell me some of the results, what do they do with their recordings? I am considering recording the noise But it would be hel...

Re: Car Horn Masking

Hi, soundproofing is very expensive. The problem is the sound of a car horn penetrates the sound of my air purifier which is about 50 or so decibels. It rumbles and blocks out a lot except car horn. I heard that if you could match the same characterisitics of the sound you are masking then you won't...

Car Horn Masking

Hi everybody, I know very little about sound editing. I have an issue with car horns waking me up. This is a pretty good example: http://www.freesound.org/people/BiblicalBricksProductions/sounds/196139/ I was thinking of sleeping to that on repeat but it is very uncomfortable and I'm not sure how he...

Re: Noise Cancellation

I apologize if I didn't read your responses correctly. However, I just want to make sure I'm not trying to delete car horns from a recording. I have car horns bopping outside my window. I thought that by sending an inverted sound through speaker would cancel it out... Maybe it would but I would stil...

Re: Noise Cancellation

Very interesting! I am trying to cancel car horns from the outside, not in a recording. I was able to achieve silence, or at least a great deal of quiet when both opposing sound waves were played at the same time (in audacity). Forgive me if this is a dumb question, but could I record the unwanted s...

Re: Noise Cancellation

http://www.freesound.org/people/BiblicalBricksProductions/sounds/196139/ I have an issue with car horns bopping. I tried inverting the sound wave. I was hoping it would be not audible to me. It sounds pretty much the same by inverting it. Any other suggestions? Thank you for the prompt response. I d...

Noise Cancellation

I read the active noise cancellation takes in the unwanted sound and uses opposing sound waves to cancel out that sound. Is it possible to use audacity or some other software to somehow take a known sound and simply flip it to cancel it out? I don't expect audacity to do this in real time but I thou...
