|
- sound
|
a sound |
|
|
- outfile
|
name of the output file |
[default = "ratzinger"] |
&optional
|
|
|
- sample_rate
|
sampling rate of the audio input file. This will over-ride the srate of the soundfile header, which otherwise applies |
|
|
- channel
|
channel number sought. If omitted, the default is to process all channels. If a value is given, only the selected channel will be processed |
|
|
- begin
|
beginning time (in seconds) of the audio segment to be analyzed |
|
|
- duration
|
duration (in seconds) of the audio segment to be analyzed |
|
|
- begfreq
|
estimated starting frequency of the fundamental, necessary to initialize the filter analysis. The default is 100 (cps) |
|
|
- partials
|
number of harmonic partials sought in the audio file. Default is 10, maximum is a function of memory available |
|
|
- maxamp
|
maximum amplitude summed across all concurrent tracks. The default is 32767 |
|
|
- minamp
|
amplitude threshold below which a single pair of amplitude/frequency tracks is considered dormant and will not contribute to output summation. Typical values: 128 (48 db down from full scale), 64 (54 db down), 32 (60 db down), 0 (no thresholding). The default threshold is 64 (54 db down) |
|
|
- brkpts
|
initial number of analysis breakpoints in each amplitude and frequency track, prior to thresholding (-m) and linear breakpoint consolidation. The initial points are spread evenly over the duration. The default is 256 |
|
|
- cutfreq
|
substitute a 3rd order Butterworth low-pass filter with cutoff frequency cutfreq (in Hz), in place of the default averaging comb filter. The default is 0 (don't use) |
