The APar element contains parameters calculated for a specific audio segment. An APar must be the child of an ASeg element. The APar element has the following attributes:
type- - the type of method. The following types exist:
- F0 - Fundamental Frequency
- RMS - Signal Energy
- Phase - Phase Spectrum
- ASpec - Amplitude Spectrum
- Fof - Formant Frequencies
- Cep - Cepstrum
- LAT - Log attack time
- CLPC - LPC coefficient
- TFA - Amplitude Spectrogram
- TFP - Phase Spectrogram
method- the method. The following methods exist:
- FO - Formants
- RMSB - Frequency Band Energy
- RMS - Signal Energy (RMS)
- F0A - Fundamental Frequency (SIFT)
- F0B - Fundamental Frequency (autocorr.)
- F0H - Fundamental Frequency (harmonic grid)
- ALPHA - LPC - Error Energy
- IRRSP - Irrelevance Amplitude Spectrum
- IRRTH - Irrelevance Threshhold
- FFT - FFT Amplitude Spectrum
- FFTP - FFT Phase Spectrum
- CEPST - Cepstrum Smoothed Spectrum
- LOFAR - Spectrum - Cepstrum
- WAVE - Wavelet Amplitude Spectrum
- WAVEP - Wavelet Phase Spectrum
- STFT - FFT Amplitude Spectrogram
- STFTP - FFT Phase Spectrogram
- STWT - Wavelet Amplitude Spectrogram
- STWTP - Wavelet Phase Spectrogram
- LPC - LPC Smoothed Spectrum
- LPAI - LPC Inverse Filter Coefficients
- LPRC - LPC Reflection Coefficients
- LPAR - LPC Area Coefficients
nx- the number of x axis
ny- the number of y data vectors
CH- the channel this parameter was calculated for.
lfrm- the frame length in milliseconds
sfrm- the frame shift in milliseconds
nfrm- the number of frames
date- the date the parameter was saved
time- the time the parameter was saved
