Pic Control With Software

[mister_e]

I know a program wich allow you to edit left/right channel. SoundForge and/or Vegas. But there's certainely tons of other who will allow that too.

For your specific need, i guess you will have to do your own app in VB or else. Send the Start message on the Serial PORT, play the wav, when it stop, send the Stop message on the serial port.

Mister_e,

Thanks for the audio editing software names; I have just got a copy of sound forge, looks like I might be able to use one channel for control.
I am hoping to put all the audio on one channel and the start/stop recording on the other using a filter.

I am also looking at the dedicated software option too, any one know how much it would cost to write a small application? I've never tried that sort of programming, pic basic is my limit at the moment!

Kind regards
Nick

Drop me a message on my e-mail. We could look at that together.

Hi,

If you use one track (of a serial file) for your control signal then you could use a couple of tone decoders http://www.x-robotics.com/downloads/...67_SE567_2.pdf to do the job. Take two frequencies for a 0 and 1. You could even use a DTMF decoder chip like MT8870. As most audio software would let you generate DTMF tones your life would get easier. Get the trial version of Adobe Audition Pro (formerly Cool Edit Pro).

Hi Sougata ,
Thanks for the info on the DTMF decoder chip MT8870, I will get one and try it. I only need to record and stop record at the moment, so it covers that with the 4 bit output.
