How do I generate a tone in only one channel? And how do I generate separate tones in each channel?

How do I generate a tone in only one channel, with the other channel being silent? And how do I generate separate tones in each channel?

Report · Apr 02, 2019

When you generate your original tone, make sure it's a stereo tone you create. Any subsequent tone should be mono. Now, using the channel controls:

... you can mute one of them - I've muted the RH channel. This means that any operations you carry out will only happen to the 'live' channel (mute button is ringed in red). So if you copy the second (mono) tone to that channel, it will leave the original alone, and you'll have the second tone on the other channel, so you'll hear both of them when you un-mute. If you just want the other channel silent, it's even easier - mute the one you want to keep, select Effects>Silence and it will knock out the other one completely.

I generated the stereo tone. I then muted one channel and tried to generate a mono tone that I could insert into the live channel as you suggested, but Audition would not allow me to do that. So, I am stuck. It won't allow me to generate a mono tone. Very difficult software to use.

I need also further instructions on how to insert the mono tone into the live channel. Do I copy it and paste it? How do I copy it? How do I paste it? Will the original tone in the live channel be replaced by the mono tone? That's what I want.

Ah - should have made that clearer - you have to start making a new tone in a separate file - you can't create more in the existing one. Having done that, you select all of it, copy it and then paste it into the channel you want on the first file. Then when you unmute the other channel, you have separate tones on each.

OK, I generated the first tone in stereo. I muted one channel. Then I tried to generate a mono signal so I could copy it into the active channel. But, Audition would not let me generate a mono signal. Only stereo. So, I am stuck again.

I don't understand why Audition is so difficult with such basic functions. No user friendliness or intuitiveness at all.

Audition isn't difficult at all from this POV:

When you go to Generate, the first thing you get is a file option box:

Select mono, and then follow the instructions above...

When I first opened Audition and generated a tone, I was offered the option of stereo or mono. I chose stereo. When I tried to generate the second tone, it went directly to the tone generation in stereo. It did not offer a menu to select mono. That's the problem.

Here is a screen shot that comes up when I select Generate, Tone. I select Stereo. Then OK. Then the stereo channel screen comes on. Then I select OK. Then I go to Generate again, but the screen shown below does not appear. It goes directly to the stereo signal generation screen.

Another problem. I opened an audio file and started playing it. But, the Stop and Pause buttons are grayed out. I cannot stop the file from playing. Who designed this program? Massive changes are needed to make it user friendly.

Here is a video of what you want, working fine. You can see both tones visible in the frequency analysis on the RHS:

Create two different tones in one stereo file

Audition doesn't need 'massive changes' to make it user-friendly, but it does require a little effort putting into learning how it works. If it was that bad, several million users in just about every radio station in the world - including a massive number in the BBC - would have complained about that by now, and by and large they haven't. In fact, rather the opposite...

As for why your stop and play buttons don't work - well, I've never had that happen but it's perfectly possible for the OS to lock you out of everything for short periods of time, especially if you are trying to play back a file at a ridiculously high sample rate that has to be down-converted to something that your audio device can cope with. Try the whole thing again at 44.1k.

I have a high end sound card that is capable of 384 kHz, 32 bit. I created a stereo tone, which worked fine, then tried to create a mono tone. The mono tone was blank. Notice in the Duration window below, the 7 kHz mono tone is blank. It has no duration.

Here is the waveform window. It has no content.

Report · Apr 07, 2019

You've created a mono file, but you don't appear to have generated any tone within it, as no time is showing - the duration doesn't exist.

I would explain to you why you don't need to use such a massive sample rate, but I'm afraid I'd expect you to ignore it.

24/192 is not a massive sample rate. I don't use 16/44.1 due to the quantization error. In any case, Audition did not give me the option of creating a sound file within the new mono file window. It just created the window with nothing in it.

What output device are you using? All modern ones have over-sampled outputs that don't need filtering, and are amazingly linear. There is absolutely no need to sample at any more than the Nyquist rate. For normal audio, especially when it comes to just tones, there is no benefit whatsoever to creating sinewaves at that rate. I seriously suggest that you don't take my word for it, and look at this: D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) - YouTube

As for your new mono wave, you didn't watch carefully enough what I did in the video. If you tried to generate another wave with the first file open, it wouldn't let you - as you discovered. So your only option is to start a new file, in this case a mono one. Having done that, and have it displayed as the active file, then you go to Generate and create your new tone. Then do the cut and paste bit and you're good to go.

I enjoyed the YouTube video. Thanks. However, I need you to step me through the entire process of creating a stereo test tone that has a different signal in each channel. The piece meal answers that I have so far just don't get it done. For example, I want to set up a 60 Hz sine wave in one channel and a 7 kHz sine wave in the other.

If you follow the video I posted earlier, and pause it every time something new happens, you'll see all the steps and can write them down - that is a real-time unedited video. I checked it carefully; nothing is missing.

I created a stereo tone, shown below. It does not look like the screen you had, which was red.

I clicked Save As, but the window says it is a Mono file. I created it in Stereo.

I changed it to Stereo and clicked OK.

I clicked File, New, Audio File, Mono. A window opened but there is no signal. It did not give me the chance to select a frequency or anything else.

So, the same thing happened as before. There is no signal generated, no duration.

So, it is still no sale.

I need step by step, in writing. No video. Click this, click that, click this, click that, etc. Do not leave any step out. Complete detail, please.

What would be the point of explaining this to you in words and clicks when you don't read them? This is what I said above, that you have completely ignored:

I should add that everybody who learns to use Audition does that best by actually using it and exploring the options, rather than being led by the nose. All the information you need is in this thread, and now I think it's up to you to discover about this for yourself.

I am exploring some other software programs that are not so convoluted.

One additional question. How do I highlight just one channel of a stereo track so that I can delete the contents of that one channel and then paste in something else?
