Demodulate the signal . After this , i want to be able to remove the DC component from the resulting signal since an audio signal should not contain a DC term. To do so, I realise i have to use a high pass filter possibly. A high pass filter I am using (MATLAB) is as follows, fsHalf=Fs/2; wl=48/fsHalf;

That way, you'll remove any sub-sonic DC related stuff without altering the audible frequency range. Use a filter with a steep rolloff. Seeing as you're doing this offline, you can use a simple IIR type and filter the signal in both forward and reverse directions to remove any phase distortion that would otherwise be imposed by the filtering.

I see this scheme for utility for eliminated.c. ( or c.c.) of one audio signal , in my case or problem of one tube amp. I work this whit one output direc os audio of one power tube amp of 12v ( to 30v depend of +B), and i have this dc of 12v (or 30v) in output direct at my speaker, and this run, but i more hapyyyyy if my speaker not receibe c.c.
DC offset and Audio Filtering – SoliCall

Removal of DC offset is not a constant addition to the audio signal since DC offset tends to change over time due to changes in temperature or pressure. The DC offset should be removed with caution. A simple high pass filters is tricky to use because some of the zero Hz signal (which is the DC) might be actually part of the original signal.
How to Remove DC Offset before Performing FFT – Origin Blog
http://blog.originlab.com/how-to-remove-dc-offset-before-performing-fft
Performing FFT to a signal with a large DC offset would often result in a big impulse around frequency 0 Hz, thus masking out the signals of interests with relatively small amplitude. Origin provides two methods to remove DC offset from the original signal before performing FFT: Using FFT High-Pass Filter; Subtracting the Mean of Original Signal

DSP Tricks: DC Removal. August 11, 2008 Embedded Staff. When we digitize analog signals using an analog-to-digital (A/D)converter, the converter's output typically contains some small DCbias: that is, the average of the digitized time samples is not zero.That DC bias may have come from theoriginal analog signal or from imperfections within the ...
Remove DC component from EEG signals

Removal of DC component means Mean removal from the signal. By doing this we can eliminate the dc, i.e., 0Hz noise. Here DC component means, the signal positive half cycles average and the negative half cycle is not zero. if x is the signal then xm=x-mean(x).
