@kingsrow I only upload raw sound if the quality is good enough. It rarely has good enough quality for me since I'm not a big audio nerd (who owns iZotop RX-5???). I've got a group of steel drum banging (washing machine) where I've uploaded the individual components so that machine thumping can happen at whatever rate you want, and the machine can cycle through whenever you want. I've also uploaded lots of rock drops or masking tape pulls, each of which is kinda neat if you abuse it for something else. I've done a few remixes through the years, but don't post most of them since they are highly tuned to my production.
Very nice! I typically just add raw recordings but I've just started mixing together a few different sources and at the very least adding a little EQ for extra punch and clarity. Check out my new fireworks sounds once they're approved! Let me know if you remix anything else. I'd like to hear it!
Hi zerolagtime, thanks for replying to my question! Thanks for letting me know also that such a low frequency occurs in a big room like that. I was indeed interested in whether such a low frequency feedback could actually occur in a real setting or whether it was only something that you could accomplish with an artificial pitch shift. It sounded realistic, so I had a feeling that such a thing could be true, but now I know :)
I used audacity to modify the original sound in case someone such as yourself found a lower pitch more effective for their project. I have experienced feedback in real settings at a variety of pitches. The shape of the room, microphone, amplifier, and speakers change the oscillating frequency of any particular setup. My rig that I used to create this sound forced it to have a high pitch, which usually only happens with loud rock bands. Feedback during speaking in a big room with nice microphones usually sounds like the pitch above.
Not everyone can imagine the variation when listening to it here since they might not know that Audacity's built-in "Change Pitch" setting under "Effects" makes this easy.
Hopefully you'll play around in there and find other interesting effects that can help you tweak a sound to your purpose. Two of my favorites are "Noise Removal" and "Change Tempo," but moving over to Spectrogram view of a channel, combined with an equalizer (or a plugin effect called Notch Filter) are pretty handy too for constant tone hums or rings.
I've got a question for you: When you say "low pitch shifted down," do you mean that you shifted the pitch down in an audio editor? Or was this the pitch of the original recording? Thanks :) and thanks for uploading these recordings - I'm finding them very useful for my purposes!
