Help me with this

Dear frends.....

I need to do some signal processing and application is as..

          I have to record some sound (near about 5 seconds)coming from
speakers of TV and then have to do frequency analysis of that data so have
to do FFT.

So, compulsory I have to use DSP Processors or any low cost solution is
there? like can I use ARM7 based microcontroller or CYGNAL-C8051 will do.

Help me on this please

Thanks very much and Regards

How soon do you want the result of the analysis?
How detailed should the FFT be?
