- Analysis Type
- The following analysis types can be chosen.
- Spectrum: Normal amplitude spectrum (power spectrum).
- Smoothed Spectrum: Smoothed spectrum by cepstrum liftering.
Smaller value of lifter length generates smoother spectrum.
- Phase: Phase spectrum.
- Unwrapped Phase: Unwrapped phase spectrum. The phase spectrum is
unwrapped so that the spectrum is continuous.
- Group Delay: Group delay spectrum.
- Cepstrum: Cepstrum.
- Smoothed Group Delay: Smoothed group delay spectrum. The smaller lifter length
makes the group delay spectrum smoother.
- Time-Domain Group Delay: Inverse FFT of group delay spectrum.
- Window Type
- The following types are supported.
- Hamming: Hamming window.
- Hanning: Hanning window.
- Blackman: Blackman window.
- Gauss: Gauss window.
- Lifter Length
-
Lifter length for cepstrum analysis.
A small value makes the spectrum smoother.
This value is valid when analysis type is ``Smoothed Spectrum'' or ``Smoothed Group Delay''.
- Always make a new window
- Always make a new window in analysis. The check is turned off, one window
will be reused for one audio file.
- Use a linear spectrum (not use decibel)
-
Use a linear spectrum instead of a decibel spectrum.
- Display a normalized spectrum
-
Display a normalized spectrum.
When the check is turned off, the spectrum will be calculated from the raw
waveform value.
- Normalization with a waveform's maximum
-
Normalize spectrum with a waveform's maximum value.
