if ends at the start of the clip).Ĭharacter string with the color to be used for the vertical line at which sounds are played. Logical argument to control if the video is formatted to be played in a loop (i.e. Logical argument to control if the video is played after generated.
Logical argument to control if progress bar is shown.
Controls whether parallel computing is applied by specifying the number of cores to be used. Numeric vector of length 1 specifying height of the video frame in pixels (see png). Numeric vector of length 1 specifying width of the video frame in pixels (see png). Numeric vector of length 1 specifying the resolution of the image files (see png). Logical argument to control if the time axis moves along with the spectrogram or remains fixed. Numeric vector of length 1 specifying the time range displayed in the spectrogram. Numeric vector of length 1 specifying the number of frames per second. Hence, you may want to adjust 'fps' if video quality is considerably affected. Note that changes in speed are achieved by modifying the number of frames per second in the output video. Numeric vector of length 1 indicating the speed at which the sound file will be reproduced (default is 1, normal speed). Default is NULL (which means from 0 to Nyquist frequency).Ĭharacter string with the color palette to be used. Default is 70.Ī numeric vector of length 2 specifying limits in the frequency axis (in kHz). Numeric vector of length 1 specifying the percent overlap between twoĬonsecutive windows, as in spectro. Ignored if 'wl' is supplied.Ī numeric vector of length 1 specifying the window length of the spectrogram, default Default is 11.6 ms, which is equivalent to 512 wl for a 44.1 kHz sampling rate. Default is '4'.Ī numeric vector of length 1 specifying the time window duration (in ms). )Ĭharacter string with the name of the output video file.
