brnomt/rockbox — reverse-engineered prompt

Build me a Rockbox fork for iPod Classic 6G and 7G that focuses on better sound controls for people using small headphones or speakers.

I want two new sound settings available on the device under Sound Settings. One should be a Bassboost effect with enable, crossover, sub bass gain, harmonics, and output gain controls. It should make deep bass feel stronger without ugly digital clipping, using a soft clipper at the end. The other should be a Crystalizer effect with enable, mid intensity, high intensity, mix, and output gain controls, so music sounds sharper and more lively.

Please wire the settings into Rockbox properly, with menu text, saved settings, and DSP processing that works on the iPod Classic ARM target using fixed point math. Also add a “Go to Album” item in the while playing context menu that jumps straight to the current song’s folder.

Make sure it builds for iPod Classic using the normal Rockbox build flow, and include any notes needed for copying the finished files to the iPod.
