First of all you need to get basic knowledge of signal and audio processing One good way to understand things 8especially about electricity is water and pipes. Now your mic is a one bucket full of water and you have to pipes (left and right) ... where does the water flow?

What I post you before is what you need - a splitter that splits the stereo L/R to a single L and single R. Stereo jack has 3 contacts mass and L,R while mono has 2. So I conclude something is wrong with your wiring. That's it. get a propper splitter and try the line in

It seems that sometimes, laptops have one input hole for both mic and line in. Some of them, as reported by other posters, can even switch from one to another function. Someone else suggested a way to check *if* mic entry is stereo or mono. Someone, like you, states that mic input is certainly mono, but someone else, also around Google, seems to state the contrary, i.e. it can be mono or stereo depending on the PC. This is important to me also because I reversed into digital form some old vynils, and did so using the mic input of my netbook, that doesn't have a line in. So I'd need to know if those *.wav files so produced are stereo or not, and, in case they aren't, repeat the operation on another machine or adding an external sound card to the netbook. >> 2) mic1 is mono; >> >> 3) mic2 is stereo. >> > > now way - such thing does not exist - one can not be two ... even easier ... > you have two ears and one mouth ... so you hear stereo, but you speak mono Also here, someone states that there exist stereo and mono microphones... >> Do you agree?

Can't you tell whether the wavs are stereo or not by listening to them? In a mixer program like aumix (curses), for example, channels which are "stereo-capable" (sic) will have balance controls (makes sense). So that might be a roundabout way (opening up the old mixer, don't you know) to reassure yourself concerning your mic (or bum yourself completely out after having converted the entire pianistic *oeuvre* of Chopin from vinyl to digital *mono*, depending). But if you are unable discern the difference by listening forget it and be happy. -- “Certitude is not the test of certainty.” --Oliver Wendell Holmes, Jr.

Mono means single btw. Good based on this conclusion a mic can never be stereo - it is a single input. You however have (at least) two outputs for boxes to achieve a stereo effect. No this single input is recorded or played equally to both outputs, thus also your output is mono. > > Here we seem to have different advices.

This is important to me also because I reversed into This is true and does not contradict to the said before. Indeed there are combined inputs. I guess it probes if the one channel is shortened and perhaps internally switches to mono input. If one referrs a mic as mono perhaps is meant what the jack looks like. > digital form some old vynils, and did so using the mic input of my > netbook, that doesn't have a line in.

You can indeed use two mics and put them right infront of the speakers, so that you avoid inference, but unless you have some exotic device there should be also a line out, which you can feed to the line in of the notebook. > Also here, someone states that there exist stereo and mono microphones... > it must be something new, but everything is possible. I don't know what is referred by stereo mic. the mic itself, then it should be two mics (two buckets), but sound spreads everywhere, so how would two exist in one and not infer - it makes no sense to me unless the jack is referred, but so we are again to ground 0. The best way to check this is to look at the jack/plug - how it looks like - if there are 3 contacts [1] would mean that the (mono) mic is providing two lines L/R (stereo output). However it is irrelevant - signal is still mono. If it has 2 contacts it would mean it is mono - good chance that you can record only left or right if recording device is not smart enough. > > The splitter works regularly when used in listening mode... > This is true - the only uncertainty here is if notebook/computer can handle the lower impedance of the mic. 1. https://www.amazon.com/3-5mm-Stereo-Jack-Adapter-black/dp/B00142BZSY

I'm not real sure what you guys are talking about, but the talk of stereo microphones leads into a mildly grey area. There are stereo microphones -- I have one, an AKG C-24. And there are a few others. It's a single microphone in that it's a single object, but it's stereo because there are actually two mics in there. You point the capsules in different directions. And there are two outputs. They're used, mostly, for classical orchestral recordings, in the X-Y stereo technique. They're rare, but they do exist. FWIW. https://en.wikipedia.org/wiki/Microphone_practice -- Glenn English

That's pretty black and white. Why you would use such a device rather than recording with two discrete microphones in an X-Y, ORTF, or MS (et al) configuration (but I read there are single, MS recording units) I dunno.

You also get units with more than 2 capsules in them. > Why you would use such a device rather than recording with two discrete > microphones in an X-Y, ORTF, or MS (et al) configuration (but I read > there are single, MS recording units) I dunno. One reason is that it's sometimes physically easier to mount (or suspend from the ceiling) a single unit than a pair. It's tricky if suspending mics to get them to point in exactly the right direction; the weight of the mic cables can drag the thing away from the alignment you want. You can't use a floor stand for mics if they have to be high above an audience (I've four floor stands that each put mics up to 14 feet above the floor, but they're not usable where audience seats are where the stands would have to be, and public safety precludes use of such things if people can trip over them or walk into them. They're eminently useful for recording sessions in halls where the public are not present, or eg for putting mics above sections of an orchestra or in front of a choir.) Another reason is on some of these mics the directional sensitivity of the two (or more) capsules is controllable from the box of electronics at the other end of the mic cables. So you can decide for each mic if you want a tightly focussed hyper- cardioid response (if you like, a shotgun mic) or something slightly directional, or figure of 8 (ie responsive to sound from both sides but not in front/behind), or omni- directional, or various points inbetween. Since no-one can put their ears where the mic is (if it's eg 60 feet down from the ceiling and 20 feet above the floor), the ability to fine tune what the mic(s) are doing remotely saves an awful lot of time. Otherwise you'd have to haul the mics up to the ceiling, adjust them, lower them again, listen for a while, and repeat. (Or lower them to the floor then raise them again ... needing several people to do that and walkie-talkies to communicate). These are the sorts of mics you often see high up in the space in a concert hall auditorium. -- Jeremy Nicoll - my opinions are my own.

As a total novice I was intrigued by the MS method's post-recording adjustability. For recording someone singing while accompanying himself at the acoustic piano I suppose you would need at least three microphones. Laying down the piano track first would probably present less difficulties. It's complicated. That's why they call them sound *engineers*, I guess. > Jeremy's post explains all this pretty well.

But they're aimed at professional users. For example, a relatively cheap thing: http://www.coutant.org/m22rp/ (this single body has 2 elements in it recording what's known as M+S - Middle & Side - where there's a front-facing microphone as well as a figure-of-8 response thing recording what's happening on each side of the microphone. It can't be plugged in to a normal pair of mixer inputs without some trickery (or in this particular model, use of the 'matrix' box it comes with). And something less cheap (if you can find one at all these days): http://www.proaudioeurope.com/info/classic-catalogue/akg-microphones/akg-c422-microphone Then there are single-body mics with multiple capsules, eg this: http://www.soundfield.com/ (four capsules; this mic gets plugged into a controller box and - if you buy the most expensive version you can adjust the width, depth & even height (for surround sound) of stereo image produced from it. It is VERY expensive - many thousands of pounds.) -- Jeremy Nicoll - my opinions are my own.

Thanks to all. The problem seems to be solved with such a cable: https://www.thomann.de/at/pro_snake_78219_yadapterkabel.htm as suggested by deloptes and other listers. The cable consists in two female 3.5mm terminations, each of them mono, and a male 3.5mm stereo. One mic at one female end, the other one at the other female end, and the male end plugged into the microphone input of my netbook. All this seems to produce a perfect stereo effect: the two channels sound to be very well separated. I'll be using the above simple connection system to live piano recording: mic 1 on the basses (left), mic 2 on the high (right). My next step is trying to add human voice, say in the middle. I'll see if this is possible by slightly complicating the above solution, without preamp or mixer or multi-channel audio interface. I'll be posting here if the attempt succeeds. Thanks again, Rodolfo <

I confess that they were not stereo. Also put together the power connectors for 5V and 12V.

Common "Stereo Shielded Cable" is commonly too fat and its use always results in ugly and unwieldy kludges. Sometimes I resorted to reusing the cables of old earphone sets, which I had otherwise no use for anymore. Cheers Eike

The ones I've soldered have bigger bodies relative to the actual connector. The really thin ones tend to be moulded. I'm not sure if I'm making myself clear ... it would help if the site actually specified what they're selling :-) Richard

But they are certainly 1/4" in the picture, the proportions are different for the miniature versions. No problem getting 2.5mm and 3.5mm mono or stereo rewireable plugs: https://www.maplin.co.uk/p/35mm-metal-stereo-plug-fj99h https://www.maplin.co.uk/p/25mm-plastic-stereo-plug-fj85g though as another poster said, they need fairly lightweight cable. -- Joe

The cable that made me possible to live record stereo from two mics, without mixer nor preamp nor external audio card nor audio interface, is a 3.5mm twin-mono-female and a 3.5mm single-stereo-male: the two mics plugged into the two mono females and the stereo male plugged into the `mic' input of my PC. This cable was solded for me by the owner of the electricity shop near my house. To add a third microphone for human voice (the former two are for piano), I plan to use a second PC as suggested by Fungi4All. This way I'll continue to do without mixer or audio interface, till the moment I'll want to do things more professionally. Now, they're just home made records... Rodolfo

Glad you got one. (My Y cables are for sharing a single stereo output into two people's headsets.) The soldering solution I proposed earlier was specifically to avoid having to deal with soldering tiny wires into tiny plugs, practical in the past but no fun nowadays. > To add a third microphone for human voice (the former two are for piano), I > plan to use a second PC as suggested by Fungi4All.

Oh my, thoughts of Itchycoo Park come to mind. (Just showing my age.) I don't think you'll enjoy listening to the results.. Cheers, David.
