Sentence examples for audio fundamental from inspiring English sources
Non-vocalic events are processed by computing Waveform Min, Waveform Max, Audio Fundamental Frequency and Audio Spectrum Flatness (ASF) as defined by the MPEG-7 audio standards [12], which capture the time-domain shape, periodicity and flatness of the spectrum in different bands.
Finally, it covers some fundamental audio algorithms and concludes with a discussion of audio and speech compression.
Throughout Examples 2 7, the performance of conventional and alternative LP models was illustrated by inspecting the PEF pole-zero plots and magnitude responses, resulting from the prediction of a noisy synthetic audio signal with fundamental frequency Hz and SNR = 25 dB.

Figure 16 Residual SFM curves for a true polyphonic audio signal with variable fundamental frequency and analysis window time offset.
Figure 9 Mean square frequency error (MSFE) and residual SFM curves of Monte Carlo simulations for a synthetic audio signal with variable fundamental frequency and SNR.
We also present a more quantitative evaluation of the different LP models, for a synthetic audio signal with variable fundamental frequency and SNR.
In most of the existing audio coding techniques the fundamental decomposition components or building blocks are in the frequency domain with corresponding energy associated with them.
Monte Carlo simulation results of the residual SFM after prediction of the synthetic audio signals with varying fundamental frequency and SNR described above are shown in Figures 9(c) and 9(d).
The features can be numerical or nominal scalars or vectors describing specific characteristics of the data such as, in the case of audio signals, tonality or fundamental frequency (FF).
In this section, we evaluate the conventional and alternative LP models described in Sections 3 and 4 in terms of frequency estimation accuracy, residual spectral flatness, and perceptual frequency resolution for a synthetic harmonic audio signal with varying fundamental frequency and SNR.
