Hi DSPGuru, Again I'm in fear whether this has been already told before. :D I read supereq method of using equalizer in BeSweet. Thanks. Then i found, foobar is also using same supereq, but here I think (Not sure) eq file has somwhat changed in file structure and file extension is *feq. Therefore i could not load it in Oagmachine. So can BeSweet/Bsn/Oagmachine/Besweet GUI could be changed to these eq files ? Which is my humble feature request.:) Thanks. Btw, one more advantage I found is that foobar supports most audio fomats and hence integrating its equalizer (actually supereq) in BeSweet would be easy to use. Thanks.
