This way sampling voice at 8kHz, 16 bit (that will take >16kbyte/sec), is reduced at 4kbyte/sec; so a 4Mbit flash will give about >130sec of speech... more that enough!! >Thanks again and good work!! >Max Might be worth taking a look at the AKM AK4309 audio DAC - an extremely cheap dac (~$1.50) with all the post-filtering on-board - bits in, audio out! Can be driven from the PIC SCI in sync mode (needs inverter in clock and bit-reveresed data).
