I just ran across your site, downloaded VRS and tested. Works as indicated. I am looking for a similar software app which would enable me to monitor certain commercials (30 second spots) that are broadcasted via FM radio at unscheduled times. I have access to the commercials recording process so I could add data or tones. Does NCH have a product like VRS but able to decode something that is less obtrusive than DTMF that cuould be used to activate the recording process?
