How make audio output mono
Is it possible to make an audio source which is mono on ONE
channel and play it as mono through BOTH channels The audio source may be a WAV or MP3 file which is already stored on the PC or it may be a line input going into the PC via a socket. Maybe there is a software utility which can do this? ---- Similarly is there a way to take a stereo audio file or source and combine it into mono then and play that through both spakers. Thank you.

A source is a piece of hardware, not a sound, or a data, etc. I believe you are thinking of a source only as something which is fed into the PC taken as a whole. However I am thinking of a source as the signal which is fed into the PC's mixer software and this may come from a WAV which is already stored on the PC's HDD. which is mono on ONE channel and play it as mono through BOTH channels Why? Mono sound is not "mono on one channel" with nothing on the other channel, because mono is not two channels. It seems obvious enough but somehow the concept was lost? I disagree. Or maybe I don't. Your definition of mono is that which is seen by the PC as incoming. However my definition of mono is that which seen by the external device which it provides to the PC. As the device in this case is not a stereo device then it has no concept of a second channel and it does not attempt to fill that channel with a duplicate signal. This duplicate would be the Right channel as far the PC is concerned on account of the left channel being associated with the tip of a 3.5 mm jack and this will be the only signal contact. If you play a mono sound on stereo gear, it should play on both channels. Why do it and if you did, it would take up twice as much (data) space. The source is a recording from a "voice note taker" and in this sort of instance there is no need (or option) for the signal to be in stereo. perhaps the issue is only signal routing. If you have a mono signal coming from a source, you would not route it to only the left or right input of a stereo recording device, it would go to both. See above. If the jack plug is a mono jack plug then it would go only to one channel (the left one) of the PC. In fact in my case there are other instances when I might use a stereo jack plug going into the PC but as I am using ad-hoc cables for the audio then only one of the two channels would contain a signal. In this case I might feed in the right channel only on account of which wires on the stereo jack plug have been chosen. The audio source may be a WAV or MP3 file which is already stored on the PC or it may be a line input going into the PC via a socket. Maybe there is a software utility which can do this? Do what, exactly? Be very specific about exact things you want to do, in detail. You have not made clear any scenario that needs software to manipulate audio channels. The utility I am looking for would take the left only mono signal which the PC receives as input and create a two channel signal which the applications downstream from that would see as mono. It may be that a software utility can not work due to the sound architecture on my PC. I don't know. There doesn't seem to be anything I can do on XP's "Sounds & Audio Devices Properties" (cpl) or the mixer (sndvol32.exe) nor on my add in C-Media Audio control panel. I figure it cannot have been too hard to have a few buttons in an application to let me select which input channel is to be "applied" to both of the PC's audio channels. It may be that a good hardware guy can tell me that shorting left and right signal leads on the 3.5 mm jack going into mic input will have the effect of causing the single channel feed to the line input socket to be divided across both channels in the PC. And maybe the same is true for a signal coming into the mic input and shorting the signal leads of the line input.

I suspect your confusion all started out because you recorded in stereo, from two input channels when you didn't have a stereo source, so when the right channel (which shouldn't exist because it shouldn't have been a stereo recording) is played back, that results in only the left channel having the signal. The problem is not that it was only recorded on one channel, it's that you recorded the 2nd channel at all! The problem is recording in stereo when the source wasn't outputting stereo. If you had recorded in mono, it would have been fine. |

If you need to repair some recordings to get rid of the empty second channel, convert them into mono, OR if you just want to do what you had mentioned for kicks (since there is no need to do it with any further recording events), any median featured audio editing software can do this, it is a fairly basic feature set of any software more elaborate than a playback or recording only, oriented utility. Someone had mentioned Audacity previously, it is free so no harm in seeing whether you like the user interface. |

I call that a source. The source in a generalized way might be considered the "computer" in a general audio context since computers are separate pieces of equipment nonessential to audio. In a computing environment, the source is the audio device itself, the sound card or the (motherboard) integrated audio subsystem, hardware. This does not change based upon what you'd "like" to call them instead. If I "liked" to call a hard drive, a "CPU" instead, would it be reasonable? Of course not. You just don't yet realize the same applies. which is mono on ONE channel and play it as mono through BOTH channels Why? Mono sound is not "mono on one channel" with nothing on the other channel, because mono is not two channels. It seems obvious enough but somehow the concept was lost? I disagree. Or maybe I don't.

You do not need to record a stereo signal. You do not need to try to artificially create a stereo signal. I take my tape recorder, which is mono, and I store the audio signal from the tape recorder on the PC on one channel of a stereo signal. "Store" it? It would be good to be more specific. And this is where the problem originates . A tape recorder with mono, one channel output, should be connected to one input on the audio device in the PC- the left channel. It is then recorded in mono, not stereo. The signa was mono as seen by the tape recorder as it left the tape recorder but when it enters the PC it is one channel of a stereo pair. No, the PC has two channel input. IF you record both channels as stereo, you have a problem because you don't have a two channel output from the source. That is why it is not only pointless, but even in some cases problematic to record stereo, two channels where there are not two channels. Do not record in stereo, it is not a stereo signal(s). I suspect your confusion all started out because you recorded in stereo, from two input channels when you didn't have a stereo source, so when the right channel (which shouldn't exist because it shouldn't have been a stereo recording) is played back, that results in only the left channel having the signal. That is what I did but there is no confusion because the recording utlity I have available will only record on one channel. Hence my request for something which will take that recording and play it through both the channels of the the sereo replay. See mt original post. No, it is recording both channels but you have signal on only one. Read slowly and carefully because I'm NOT going tell you again this basic necessary fact, the entire answer to your problem: You are recording in stereo, you are recording two channels and that is the problem. The second channel is being recorded without any signal from the source. The only thing you need to do, should do, is not record in stereo. "Record in stereo" means your CHOICE of what to do, not what it does. So, you change the settings in the recording software. If the software is crude, crippled and has no such adjustment then pick one of the myriad softwares that has this basic, common setting. The problem is not that it was only recorded on one channel, it's that you recorded the 2nd channel at all! The problem is recording in stereo when the source wasn't outputting stereo. If you had recorded in mono, it would have been fine. I agree but if the utlity does not permit it then I post to the Usenet and ask "Is it possible to take an audio source which is mono on ONE channel and play it as mono through BOTH channels". What utility again? When any normal audio recording (capable) software records a mono, single channel, it creates a one channel audio file. That is the goal. When stereo devices play back a one channel audio file (at least common ones, like a PC), the mono is output to both "stereo" channels, the left and right, not only one. The only time the mono is output to only one of the two channels on a PC is if it was not recorded as mono but as stereo. In short, it's not a stereo signal, don't record as stereo. If that quotation is a struggle for you then think of it like this "Is it possible to make an audio source which is mono (AND RECORDED ON ONLY one channel) and play it as mono (IN THE SENSE OF THE SAME SIGNAL COMING through BOTH channels)? You need to just do what I told you. It's not going to make sense to you till you do it, apparently. [I have used capitals to make it easier to see what I have added to help with the comprehension.] Hope you get it now. I'm not the clueless one here. You have two problems: You are choosing to record two channels when you only have one. You are choosing to ignore standard terms and try to argue as if you know what you are doing when clearly you do not- as this is a very basic task. |

And this is where the problem originates . The signa was mono as seen by the tape recorder as it left the tape recorder but when it enters the PC it is one channel of a stereo pair. In your case, the easy solution would have been to attach the output of the tape recorder to both sides of the stereo input. At home, I could easily do this with a couple of adapters and an RCA cable. Mono RCA to stereo RCA adapter (feeds the mono signal from one RCA plug to two RCA jacks), then to a cable with stereo RCA plugs on one end and a stereo 1/8" plug on the other (commonly used to connect a PC's sound card to audio equipment). Another solution is use your existing mono cable and record using Audacity, setting Audacity to record mono instead of stereo. Audacity will also convert your existing recordings properly. Just use it to split the stereo WAV into two tracks, delete the one that's nothing but silence, then use the export command to export a new WAV of just the mono track that you kept. I agree but if the utlity does not permit it then I post to the Usenet and ask "Is it possible to take an audio source which is mono on ONE channel and play it as mono through BOTH channels". If that quotation is a struggle for you then think of it like this I think everyone but you thinks that your orignial question was (and still is) poorly phrased. If you had a mono WAV file, it would play through both channels on the PC without any special software. What you have is a stereo WAV file with sound on one side and silence on the other, since you recorded it incorrectly. You used both a cable and recording software that could not properly handle the mono signal. If you had just one of these right, it would have sounded correctly, even though in one case you'd have a WAV that's twice the size of what you need (i.e. a stereo WAV file with the same sound on left and right). Your best solution, short of re-recording everything on the PC properly as a true mono WAV file, is to edit the (bad) stereo WAV you've got into a WAV that's mono. Audacity is freeware and there are many Audacity tutorials on the web. Jeff -- Remove icky phrase from email address to get a valid address. |

While I agree a splitter could be used to end up with a mono signal on two channels, it is best avoided, it will degrade audio quality. Typical computer gear (practically everything) has low quality input coupling capacitors and a typical voltage divider on the input signal. The caps and resistors are likely not even well matched. By putting the signal through them twice (both), it degrades it more. Later dropping one chanel or mixing them will still be worse than if only one channel was recorded in the first place, or even recording both channels as he had been doing (with signal only on the left) then using an audio editor to just throw out the right channel. |

Kony, you are a bright lad. There can't be too many possibilities to think about. For your benefit - I take my mono tape recorder and I plug in the tape recorders output into the line input of the PC. I take some software (in my case Claudio) and play the tape recorder so that Claudio can *store* the sound wave forms coming from the tape recorder. Claudio can then keep the sound in its own internal format or export it in MP3 or WAV format. There. Did you spot the word *store*? And this is where the problem originates . A tape recorder with mono, one channel output, should be connected to one input on the audio device in the PC- the left channel. It is then recorded in mono, not stereo. It is recorded in momo but it is one channel of a stereo pair with nothing on the other channel.

IF you record both channels as stereo, you have a problem because you don't have a two channel output from the source. BINGO. Now go back to the original posting. I would use any such utility as I was asking for to be able to record the mono coming into the L channel as mono on the two channel ausio which the PC defaults to using. That is why it is not only pointless, but even in some cases problematic to record stereo, two channels where there are not two channels. Do not record in stereo, it is not a stereo signal(s). That is true but I have got recording which are now single channel because they were incorrectly recorded in stereo. hence my request for a util which mixes bith channels into one.

If the software is crude, crippled and has no such adjustment then pick one of the myriad softwares that has this basic, common setting. Now that has to be my prerogative. I would prefer to add a small utility (see my OP) which would take the signal from one channel (or both channels for that matter) and mix the signals such that they appeared in both channels. Why do you want to give me long and pointless lessons in audio when I have defined the parameters I can vary and I have asked for information about a solution within those parameters. It seems that you just want to quibble that my original tape recording stored as a WAV file (see above) is not a SOURCE of audio signal for the PC's mixer and therefore I should not refer to it as a SOURCE. The problem is not that it was only recorded on one channel, it's that you recorded the 2nd channel at all! The problem is recording in stereo when the source wasn't outputting stereo. If you had recorded in mono, it would have been fine. I agree but if the utlity does not permit it then I post to the Usenet and ask "Is it possible to take an audio source which is mono on ONE channel and play it as mono through BOTH channels".

That is the goal. When stereo devices play back a one channel audio file (at least common ones, like a PC), the mono is output to both "stereo" channels, the left and right, not only one. Now that is new info for me and one I will thank you for (assuming it is true!) So how do I null out the right channel on the recordings of a mono source which Claudio has recorded as stereo? From what you say above I infer that the PC will detect the absence of the R channel (or maybe there is an additional flag which needs to be set in the WAV) and then the PC will replay the signal in both speakers. Personally I don't want to go through all my recordings and do this and I would much prefer a utility which I could run and which would simply take one channel of the two channel signal and replay that through both speakers. The only time the mono is output to only one of the two channels on a PC is if it was not recorded as mono but as stereo. In short, it's not a stereo signal, don't record as stereo. If that quotation is a struggle for you then think of it like this "Is it possible to make an audio source which is mono (AND RECORDED ON ONLY one channel) and play it as mono (IN THE SENSE OF THE SAME SIGNAL COMING through BOTH channels)?

The possiblities are apparently many, because in those possibilities lies the way you are doing it, which is causing problems, and the way others do, which works. The recording software and settings are quite a combination of variables in themselves. Your attitude is self defeating and yet I will show one last bit of mercy and address your issues one last time before exiting the thread. That is true but I have got recording which are now single channel because they were incorrectly recorded in stereo. hence my request for a util which mixes bith channels into one. To permanently fix them, pick any audio editor, not "utility", except that you do not want to "mix both channels into one", you'll want to drop the right channel entirely instead of mixing it, then save the WAV. For MP3, I don't typically do this with MP3 so I cannot tell you which audio editors can discard a channel and losslessly retain the original MP3 compression instead of recompressing it (or whether this additional loss of quality is significant enough to matter, as often on old tape recorders the quality isn't high to begin with). Same would apply for a playback only software, you'd not want to mix but rather, discard the R channel and play the L through both. Why do you want to give me long and pointless lessons in audio when I have defined the parameters I can vary and I have asked for information about a solution within those parameters. I never did want the long and pointless. Quite the opposite, you started out with misconceptions and ideas about splitting mono into two channels, now combining them, now small utilities when you haven't even a basic audio editor software. All we ever needed was for you to stop trying to guess your way through the problem and instead post the concise specifics of exactly what you were doing (not generic details but specifically what you did in detail, what YOU did, not an overview of "audio" in general as you see fit to reinterpret it.). So how do I null out the right channel on the recordings of a mono source which Claudio has recorded as stereo? Pick an audio editing software. Just grab the first one, you are not doing anything advanced. Audacity is free and was suggested by the first reply to your post. From what you say above I infer that the PC will detect the absence of the R channel (or maybe there is an additional flag which needs to be set in the WAV) and then the PC will replay the signal in both speakers. This is a typical feature of the player software, a default action, so uncommon to want to change that many players dont' even allow any other method of channel mapping. Personally I don't want to go through all my recordings and do this and I would much prefer a utility which I could run and which would simply take one channel of the two channel signal and replay that through both speakers. "Media Player Classic" will allow playing back your misrecorded files on both L & R channels if you go into the configuration menus and select "View"-"Options"-"Internal Filters"-"Audio Switcher"-"Enable Custom Channel Mapping" The channel box and checkmarks should be obvious enough. It will remember the setting. Since this is also inconvenient for purposes of playback, having to manually select the player, you might consider giving the misrecorded files a different filename extension then associating only that extension(s) with MPC. For example, if it's an MP3, rename it "audiofile3.mp3screweduprecording"... which is a joke name but if it were clicked in windows, you then have the default action to prompt for what you what to open it with and to set that as the default, but playing back the rest of the (properly recorded or edited to be corrected mono) files with something else that isn't set to this default action. http://sourceforge.net/project/showf... ase_id=403110 |

I think it must sound like that to you and to many others. However the recordings have nearly all been made and they are, sad to say, not made in the usual way. Personally I find that recordng mono by shorting out two stero leads a very common requirement. And less cdommon is to create mono from stereo by using exra leads. So what has been doen has been done. We can't re-invent it. I must do what I can to deal with it. |

So what has been doen has been done. We can't re-invent it. I must do what I can to deal with it. If one knew the parameters that made the stereo, I think a reverse flow would work. Complex and probably impossible otherwise. Using DSP this may have been done to get the stereo. I once made a mono to stereo circuit using caps and resistors. Worked pretty good. If I reversed the frequency and phase components, I bet I could reverse flow it. greg |
