Simultaneous recording and playback

[walkerp]

Greetings--

I am looking for a solution that will allow me to begin playback (plus rewind and fast-forward) of the audio while still recording lengthy audio via webcast and telephone calls.

Previously I was able to accomplish through Total Recorder's split track feature. I would begin recording and every ten minutes (as determined through settings) it would save the first file and continue recording with a new file name. This would allow me to open the first file in a separate media player for playback while the rest of the program continued recording. Unfortunately this is not working well now with Windows 7 and we are seeking alternatives.

*Freeware is terrific, but stability and OS flexibility is a priority.
*Ideally this would be embeddable into our software.
*We are able to make this work for multiple stand alone licenses, however an ideal scenario would be a single program capable of recording and playback of 35+ simultaneous audio programs.

To me this should be simple in today's DVR day and age, however I have not found a stand alone audio recording program and am not able to sacrifice storage space for a/v recordings. All help is greatly appreciated.
