Hello AAC, I posted another thread asking for help to create this project. It is based on a White Noise Generator as input, with a triangle wave generator, and lastly a filter to amplify and fix the frequency in order to obtain the realest Ocean wave sounds, and an output speaker. This is what I've done so far but I need some feedback as to what I could be missing/add/modify. Any help appretiated. Thanks!

this is the white noise generator
this could be another one but i don't know if it could be used for the triangular wave below....

This is the triangular wave generator....

 

It seems to me that you can make a triangle wave good enough for audio with (1) op-amp.

ps. The LM741 is a bit of an antique. You can get much better specs in a newer version.

 

White noise will not do it, the sound is far to bright. What you need is pink noise (derived through a filter from white noise) or better yet the noise used in sound masking generators (sometimes called magenta) to recreate the sound of rain. E

how about ocean waves? what method would you recommend me for doing this?

Look at post #7 in your duplicate Thread.
