I am interested in exploring the 29F010 flash chip as a means of audio sample storage and manipulation. This is a basic setup whereby a sample is stored in the 29F010 memory, and is recalled in a loop continuously.
The basic idea is this: A square wave is generated, which in turn generates a set of address bits, which in turn are sent to the 29F010, which recalls each sample located at that address, which is then presented at the digital data outputs of the 29F010, which in turn are sent through a resistor to resistor ladder, which acts as a digital to analog converter.
By manipulating the address bus, we can change the order in which samples are played and thus change the sound.
