Parrot: Auto voice record and playback

Rayman

This copies a little gizmo I saw at Radio Shack a few years ago...

It uses the demo board's microphone (voice activated) to record·a second of audio.

Then, it plays it back out the speakers a second later.

After this, it will randomly either repeat or record again.

Of course, this idea could be extended into a WAV recorder...

Have Fun!

Thanks!

It is on my list of things to do to make a retro tape recorder emulator.
(With record, rewind, ff, play, stop - but records on flash instead of tape)
I'll probably start with a version that records raw sectors of PWM (*)
and then maybe later do another one that makes FAT wav files for each recording session. (*)

But I'm a slow deep thinker so feel free to beat me to the finish line and we both .

(*)Legality? First method seems compliant with 17 USC sec 1008 and preceding sections (Audio Home Recording Act)
Second method I'm not sure I can stretch my interpretation enough to cover it.
Edit:solved. Programmable Computers and Programs are NOT "recording devices".

This works good for recording something short like "Boo!" for Halloween effects. Nothing else is needed to store the record except the Prop chip itself.

Thanks for posting this 5 years ago, Rayman.

Thanks for digging up this old thread... this really is a long neglected aspect of the Propeller Demo Board and looks like a lot of fun to impress kids with.

You don't have to have it say "boo" to be a Halloween feature... just a mysterious parrot.. unseen, but heard will offer up lots of fun. Just make sure that the mysterious parrot is loud enough, but coming from an impossible to determine source (maybe a ceiling speaker).

i suppose you could play with the timing and have it be a weird echo of sorts

Here is a variation with ECHO capabilities I used in a Halloween application.
