I have the buffered Cold Gold/contactmicrophones.com contact mic. If you do a search for "cold gold" most of the sounds I've recorded so far should turn up, but in particular I enjoy this one:
I have absolutely no experience with any other contact mic except that one, so I can't say exactly whether or not I would be more happy with something else, but as far as I can tell it does exactly what it should and even after I managed to melt the glue a bit after recording a burning hot radiator (see above) several times it still works just like new.
In am very interesed in going deeper into the exploration of resonant objects and vibrating surfaces and after doing some experiments with simple DIY brass piezo mics I´m considering to invest some money in a few already built piezo mics/pick ups since I am very clumsy and therefore lazy to be able to improve too much what I have know. After doing some research surfing the net and the archives of this list, these are the choices I am thinking about:
ACOUSTIC-LENS (( top in my list and the most expen$ive with difference ))
http://substation.co.nz/blog/?p=88 <--- after reading this enthusiastic post on them and listening to some examples I feel very tempted of trying them...
this guy seems to be reliable and has good prices and a variety of basic, improved and more exotic custom-made mics. those are the ones I am considering among his catalog:
10 Foot Buffered Mic - $70 USD each (weight: 100g) -- Buffered Contact Microphone (with Preamp)
10 Foot Mini Stereo Set - $55 USD each -- Basic Contact Microphone
10 Foot Suction Cup Contact Mic - $48 USD each ((( interesting to record body sounds )))
10 Foot Buffered Hydrophone - $85 USD each
10 Foot Stereo Hydrophone - $55 USD each
I find interesting also the piezo-film mics (the response seems to be better according to some comments I read and are good to attach to non- flat surfaces). Not available temporarily from that guy though. I found also this link: http://www.windworld.com/products/msipu.htm
So, I think the use of some buffered / preamp ones would be definitely a right choice to improve the recording of very tiny sounds (one of my aims) without getting excessive noise. With the DIY piezo discs I have now I miss a wider freq range and above all a good low freq response that seems would be resolved with some of those.
Please, tell me about your experience with any of those in particular or with other mics and these kind of recordings in general, which preamps do you use...tricks... whatever....
Also... has anyone used the Acoustic-Lens? I only found that guy using them for phonography purposes and I would like to know more comments on them before even thinking about investing so much $$. Also, since those sellers are in USA/ Canada, tell me if you know any similar alternatives in Europe.
I search a little, and found theses links:
And here is a text about a very cool hoax -Belgian researchers have been able to use computer scans of the grooves in 6,500-year-old pottery to extract sounds -- including talking and laughter -- made by the vibrations of the tools used to make the pottery.
If only it were true. Some fiction should be true.
in my opinion, something like this is possible...
BUT, :evil: , for that case,
someone say that it’s a 2005 April’s Fools joke,
check the peoples comments:
You know sometimes Sounders like me
will change the tags of theirs sound,
so this is just regular that for the same keywords
you don"T get the same result in some cases...
If your search don"T give good results try to use this tips,
on Google write:
"site:freesound.iua.upf.edu street flower etc"
another example here:
"site:freesound.iua.upf.edu big explosion"
you will get more intelligent results in some cases, :twisted:
Yes check at:
for now only the source is available in the trunk repertory
I will put an compiled zipped files for win32 nearly
It looks like the formatting of the search page is mangled...but if you scroll down you will find your search results.
I can't compile it I think I did everything according the documentation. Installed a lot of stuff. set the variables..

For the love of the devil, use paragraphs.
You will have to post (at least examples of) the tracks which you want cleaned to get some help I believe.
I don't think your doing anything wrong because the same thing happens to me also.
For now try using either the SAMPLEPACKS or use the TAGS to see if you can find what your looking for.
If quality is not too important then a simple mp3 converter is all you need - I use the free winlame software which will reduce the file size to about 10% of the original - that should be about right. You will not notice a drop in quality on ordinary PC speakers. Just google winlame. It has options to reduce quality further if needed. 128kbps is the sample rate - the sound is recorded in 128,000 samples per second - the more the samples the better the quality but it is important to remember that resampling at a lower rate will reduce quality but no amount of resampling can add anything that was not there!
Yep, that's exactly what I was looking for, thanks.
PerfectPancakes: Just want to confirm hammerklavie's answer, that if you upload to freesound, you should upload the bigger file, as it has a better quality and is better for editing.
Hi, you could also give this a go http://www.sofotex.com/Simple-MP3-Maker-download_L4564.html
Thanks very much for your very quick reply. i tried audacity but does this not just cut down the length of the file thus reducing it? its a peice of music i have and i wondered if i could compress it somehow without cropping it if you get what i mean (im sure you do) to be honest quality is not a big problem here as i only want the sound to play in the back ground of a 360 degree virtual tour its just a bit of fun really but will no doubt turn very serious when i learn to do things properly.
So can audacity just reduce/compress the file as now ive included the sound in my virtual tour its uped the file size to 6mb and ideally these should be about 2-3 for quick download time
Hi i have a music clip that is 5mb in size i want to get this down to about 500kb so i can upload it my web page but does anyone know how i can do this,what programme is required etc. Also the file says its 128kb per second what does this mean is it good or should it be less/more and if so how do i go about vhanging this to.
the top question is most important to me though.
i shall also be uploading a lot of files and sounds of various things for you to use when i find how i can reduce the size as no one wants to download 5mb files do they?
im a newbie to all this sound stuff and this website seems the place to hang out so hi all i like whats going on here
Hi im new to this site and found it about a week ago and downloaded a cool sound. So i come back today and search for another sound and nothing, everytime i search for a sound like street or waves nothing returns am i doing something wrong is it to do with my settings on pc or what.
would greatly appreciate if someone could point me in the right direction
oh nae bother, had a lot of fun. be lucky ingsey :0)
Well, just for your information, that child's bbc website freaked the crap out of my daughter so try not to make a website so startling.
Well I thought i'd have a try our find it here: http://freesound.iua.upf.edu/samplesViewSingle.php?id=50847
