Ok so I made this nice sound system for our pyromusical shows and the system sounds great using normal stereo sound tracks mixed to mono on a mixing board, but when we play the show track witch is one side of a stereo trackl it dose not sound so good. The software that makes the sound track for the shows has to put timecode on one of the stereo tracks. I think it just writes over what ever was on that channel and we are loosing whatever info was there. I would like to properly mix the two stereo channels into one and feed the pyro software two mono channels.
Whats the best way to mix stereo channels into one?
Right now we use Goldwave for editing, I have not played with it much, and dont know if it can do it.

GoldWave has the capability. Open your audio file and select the Effect pulldown menu. Select Stereo and another menu appears to the right. There you will see Channel Mixer, "mixes or combines the left and right channels." A new window will open allowing a choice of various settings. The default is 100% left and 0% right mixed with 100% right and 0% left. That sounds like what you want, though you could mix the mono to one channel and have the other "stereo" channel to carry your timecode.
edit: let me start over...
You can convert to mono by just opening the file in GoldWave and saving as a mono file.😀
You can make a stereo file with one channel for the timecode by following my original instructions, but when the Channel Mixer window opens, set the left & right volume % to 50% for each. Set the volume % to 0 for left and right for the channel you wish to use for the timecode. One channel will be the audio and the other will be silent.
edit jr: You can make a dual mono file by setting each of the left and right volumes to 50%.

Thats what I need but is it the best way to do it. Does Goldwave just lay one side over the other? Would I be better off using some kind of an algorithm to mix the two sides?
I am thinking that there is some magic to still getting good sound after mixing stereo channels. I just cannt seem to find the right info on the web. However I have read that mixing some tracks can cause some cancellation depending on time differances in the tracks.
Yes and no. Maybe someone else can pick up here. Truth is, I don't believe there is any magic to getting good sound. And I have no knowledge of the track-mixing cancellation you are referring to.
OK I looked at the waveforms today.
I put one song thru the time code software and compared the one channel that had the music on it to the two original channels. The modifyed channel looked nothing like ether one of the original channels. Maybe it was sumed, hard to tell. Sent the software company an email to see if thay could tell me what the software does to the two channels when it combines them to one. more to come. Andy

Fould this from Berkeley about Audacity

An ideas?

But it does not explane about the quality loss.

Hi,
There is utterly no rocket science to converting stereo to mono,
you simply combine them by adding them together, there is no
special algorithm for it, you simply lose the stereo information.
Its exactly the same as mono and stereo TV sound and FM radio.
Mono is not losing one of the channels, they need to be added.
rgds, sreten.
Stereo can be regarded as the sum and difference of two channels.
The sum is the mono signal, and the difference the stereo only signal.

I've been using Goldwave for years and haven't had any problems with Stereo to Mono.
Maybe the timecode software is messing with the file.
Can you post some clips of the files before and after? Just a few seconds should be OK.

My guess would be that the SQ loss is not from literally losing part of the signal, but that the signal from one channel can get swamped by the signal on the other as a result of the summing. Maybe "lessening of SQ" would be more accurate, but it should be very slight, yes.
Hi,
No it doesn't because its referring to losing the stereo information.
Your quality loss is due to losing one stereo channel of information.
rgds, sreten.
I dont know that for sure yet. But it seems the stereo to mono conversion can only be so good. We will pick the best converter and work from their. In the mean time what if I tryed a stereo enhancer on the mono channel before playback?
Hi,
Well I pretty much do from your description. The "best converter" is
a simple summing circuit, which can be 2 resistors into one input.
Just create a file with the same mono on left and right, when the
time code replaces one channel, there will be no quality loss.
rgds, sreten.
