error: Input not stereo
 
An mp3 I have is an old song back from 1957.
When i try to "Vogone it" I get the "Input not stereo" message.
I guess that means it was originally produced in Mono. Is there a way to "Songvert that" to a stereo sample somehow. Or even an audio program that anyone knows of.

Oh, I have the original 45 as well, is there a way to import that into my computer somehow as something that will appear to be stereo, or am I just totally out of luck on this song?

Bryant my guess is being that old it was probably originally recorded in Mono. Have you tried searching for a remake that would be in stereo.

Almost any audio editing program that recognizes MPEG(MP3) format should be able to resample the track to a stereo track.

I've done that many times with mono .WAV tracks using Goldwave, which lists MPEG(MP3) as one of their formats in their conversion list.

How is it typically done with these programs, is there an option to check off (what typically is that option) or does it just happen during a normal conversion?

I'm not certain I understand your question.

You select the file(s) you wish to convert and select the paramaters you wish to convert it(them) to.

bryant August 30th, 2007 08:05 PM

Oh, I was asking if there was any other "special" selection o I needed to do to make sure they would convert to a stereo format.

I think i've done what you said and songverter brought the file to a double speed (plays fast-like a chipmunk sound).

George August 30th, 2007 10:48 PM

Rerad my post.

Who said anything about using Songverter? It is not an audio editing program.
It converts files from one format to another.

bryant August 31st, 2007 12:01 AM

I did read your post (or i wouldn't have responded), apparently, I did not understand.

I have some audio editors and still did not know how to
make a mono file to a stereo file. I'll have to experiment, I guess.

I think the reason why I brought up songverter is the fact that you used the word "conversion" in your explanation, and that is what songverter does (convert).

The short answer to your problem is it can't be done!!
OK - there are progs that will convert a mono wav file to a stereo file - but in reality all you have is 2 identical (mono) tracks:e
You are bashing your head against the wall trying to do the impossible!
There is further historical and background info on this in the Vogone Manual.

Will take issue with that.

Of course you wind up with duplicate tracks. It would be foolish to think otherwise.

However when dealing with a program such as KHP that requires a stereo track fpr processing, or Microstudio that will not play an 8 bit mono track one has no alternative but to convert it to a 16 bit "stereo" stereo track in order to use it.

The original question was is there a way to convert mono to stereo and the answer is yes.

Will the new Vogone with it's wider panning capability be effective with it? Who knows? It may very well remove the desired frequency range in both tracks, or it may not.

I'd sure try it if I had the need. The very worse that could happen is I'd wind up with a track that could be used in other applications.

As you are well aware, the latest version of Vogone is absolutely fantastic!!
The results that can be achieved when working directly from a suitable modern stereo studio-based (multi-track) CD recording are truly outstanding - not only removing the lead vocal but significantly enhancing the remaining background music.
However, attempting to remove the lead vocal from a pre-stereo recording source will fail - and working from an mp3 file will only make matters worse.
There is no problem converting your old 45rpm record to a digital stereo audio (wav) file, however to the best of my knowledge, no 45s were ever recorded in stereo - which generally speaking was not used in recording studios prior to 1960.
It's quite frustrating because so much fine song material pre-dates this point in time. Probably the only hope you have is to try and find a modern-day recording of it.

ddouglass August 31st, 2007 10:31 AM

Or a newer re-tracked production. Even the older studio productions were multit-tracked, but then added together to make a mono output for 45s. Many studios have done re-releases of the older song digitally re-tracked for stereo.

Well there, you answered my question that I asked.

next: How do you do it and with which program, then i will obtain that program, follow your instructions, and move on and take my chances?
Thanx,

I use an audio editing and mastering software program by Steinberg called WaveLab. There are lots of other (much less expensive) progs that will do the job - I think this one may be able to do it. I'm not personally familiar with it but this looks like a good place to start looking:
http://en.wikipedia.org/wiki/Audacity

Today I recorded the contents of an old 33.1/3 rpm record to my HD using WaveLab.
To do this all I do is connect the record player to my Amp which has an audio output connected to an input on my Creative Audigy2 external i/o Sound Module.
(Actually I think this sound card comes with everything you need to do what you want - however because I have WaveLab I don't use these tools. It also comes with some very informative and detailed manuals on Music Creation etc.)
I also have another little gadget called PowerWave - a USB Audio Interface & Desktop Amplifier. It's a very small but remarkable device by Griffin Technology. This is what it does:
Archive records and tapes to make MP3s or CDs
Record instruments or voice into your PC
Connect and power any set of home stereo speakers
Use as a standalone amplifier for iPod/MP3 player
Zero latency monitoring for multitrack recording

You might like to take a look at this program too:

Don't get too excited - in actual fact all it is is two track mono:e
There is no way ( that I am aware of) that a mono recording can be converted into a true stereo recording.
Conversely, it is possible to convert a stereo recording to mono.

Not sure I understand your question.
I have made several responses in this thread.
If you are referring to previous threads etc, I usually find I am fully occupied with ongoing beta testing.

NoI was referring to this thread.

I posted right from the very beginning that a mono could be resampled as stereo, agreed it would be two mono tracks, explained athat the 8 bit mono vs 16 bit stereo would be the resulting improvement, and you act like I'm surprised at you finally agreeing with me that it could be done, which Bryant acted like he was hearing it for the first time in your post, and on and on.....good grief.

All that considered, my WOW post was sarcasm (not directed at you) which should have been obvious to a tester with a trained eye, because this :r is a sarcastic face.

Case closed. No need beating it to death. I too have better things to do.
