hello,

i'm working at a project. it's a digital effect processor for singing, something simple just some delay and reverb, but i don't have enough sram memory on the stm32f407...the conversion is on 16bits at 48khz and minimum 3sec that need to be stored for few seconds and than transmited at output with the delay...how can i solve this?...what type of memory do i have to buy and how much, or please give me some alternatives...
