I need to build a noise generator for an experiment. I need to store

Any ideas how one can implement such a thing?

Thanks for your help.

Search Digikey for ISD4004.
Note: They also have direct pushbutton devices, but I'm not that
familiar with them, or how much audio storage they have. Duration is
trade off with fidelity.

I'm thinking the ISD4004 (available in DIP), and a small inexpensive
micro might get you close to budget. The R2R would get you there too,
but might be more difficult to implement to code.?
