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?

    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.

    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.
