Hello All:
I'm building a system where I need to transfer PC type wav files from a host to a remote. The remote systems can be located very far away and a modem is about the only answer in those cases. The modem will also slow sown to 33K baud or less.
These wav files are either 8 bit or 16 bit mono at sampling rates of 11 or 22 KHz. The transmission time is a problem.
So my questions is what are your ideas on speeding this up..............
- Zipping the original file gives me almost a 2:1 reduction is size. I'm running a NIOS processor (ARM like) at 50 MHz. So I could unzip at the receiver.
- Has anyone looked at only sending deltas. Send Sample 1, Send Sample 2 - Sample1, Send Sample3 - Sample2 ...... If the change is small the deltas will be small and perhaps less data.
Any other ideas.
Thanks George
