Fons, Dennis, davic and Lorenzo, Thanks very much for your responses to my question. I never thought of GNU Octave and gunplot for this task, mostly because of the extra steps it would require to listen to the resultant audio file. But, there are definite posibilities there. I've never heard of PureDAta or CSound, but will explore these programs. I also wasn't aware of Sonic Visualizer or Glava, but will explore these, too. Thanks, again, for your advice and guidance. I really appreciate your work to assist me. -Kevin On Tue, 2024-02-20 at 12:00 +0100, > > Message: 1 > Date: Mon, 19 Feb 2024 14:41:49 +0100 > From: Fons Adriaensen <fons@xxxxxxxxxxxxxx> > Subject: Re: Teaching tool to visualize waveforms? > To: linux-audio-user@xxxxxxxxxxxxxxxxxxxx > Message-ID: <ZdNanb9LkIQ2IduF@xxxxxxxxxxxxxxxxxxx> > Content-Type: text/plain; charset=us-ascii > > On Mon, Feb 19, 2024 at 09:21:37AM +0100, Lorenzo Sutton wrote: > > > On 18/02/2024 21:11, Kevin Zembower wrote: > > > > > However, we never saw a visual representation of the combined > > > waveforms.
