To import the audio file into MATLAB workspace, use the ‘audioread’ function. Refer to the link below to get the details of ‘audioread’ function: The first link gives examples of power spectrum computation for audio signals. The second link is about the ‘dspdata.psd’ function which computes the power spectral density.

we see that this expected power can be computed as 1 Z +∞ 1 Z E{y 2(t)} = Ryy(0) = Syy(jω) dω = Sxx(jω) dω . (10.3) 2π −∞ 2π passband Thus 1 Z Sxx(jω) dω (10.4) 2π passband is indeed the expected power of x(t) in the passband. It is therefore reasonable to call Sxx(jω) the power spectral density (PSD) of x(t). Note that the instanta

Power spectrum and power spectral density are agnostic to the type of signal that is used to generate an intensity distribution in the frequency domain. Such a signal could be a broadband noise measurement , a harmonic analog signal, or a wideband signal of any type.

Waveform and 16k FFT Spectrum of a 48 kHz Fs digital sine signal with 8-bit dither (level = -20 dBFS; frequency = 1125 Hz). The FFT Spectrum result (sometimes called the linear spectrum or rms spectrum) is derived from the FFT auto-spectrum, with the spectrum being scaled to represent the rms level at each frequency.

Spectral's close ties to leading edge Silicon Valley companies have enabled us to consistently take the initiative in adapting state-of-the-art technology to audio use. The DMA-100 Power Amplifier. Appearing in 1982, the DMA-100 class A amplifier was the first power amplifier to meet the standards of the Spectral performance envelope.
