I'm a product design student. I'm not familiar with the terminal or writing code. Please build this for me with HTML, CSS, JavaScript and native Web Audio. Make a simple, usable browser page, with no external libraries or internet services. Sound should start only after I click. Use comfortable initial levels. I need to play with the result, not read code. Extend the noise app with a sine-wave LFO. First let it move the noise volume around its base level. Give me rate, depth and off. Then let me choose filter frequency as an alternative destination, with a sensible range. Only the selected parameter should move. At 0.1 Hz I expect one cycle every ten seconds. Turning it off restores manual control. Keep attack and release. Show the movement while it runs. I want slow breathing textures as well as audible tremolo.
