 #### Arguments
 
+- `dim` *str, optional* - Whether to plot hpss in one (i.e. waveform) or two (i.e. spectrogram) dimensions. Defaults to 2.
 - `n_mels` *int, optional* - Number of Mel bands to generate. Defaults to 128.
 - `fmin` *float, optional* - Lowest frequency (in Hz). Defaults to 0.0.
 - `fmax` *float, optional* - Highest frequency (in Hz). Defaults to None, use fmax = sr / 2.0.
 kernel_size (int or tuple, optional): Kernel size(s) for the median filters. If tuple, the first value specifies the width of the harmonic filter, and the second value specifies the width of the percussive filter. Defaults to 31.
 margin (float or tuple, optional): Margin size(s) for the masks (as described in this [paper](https://archives.ismir.net/ismir2014/paper/000127.pdf)). If tuple, the first value specifies the margin of the harmonic mask, and the second value specifies the margin of the percussive mask. Defaults to (1.0,5.0).
 - `power` *float, optional* - Exponent for the Wiener filter when constructing soft mask matrices. Defaults to 2.0.
+- `top_db` *float, optional* - threshold the output at top_db below the peak: max(20 * log10(S/ref)) - top_db. Defaults to 80.0.
 - `mask` *bool, optional* - Return the masking matrices instead of components. Defaults to False.
 - `residual` *bool, optional* - Whether to return residual components of the audio file or not. Defaults to False.
 - `dpi` *int, optional* - Image quality of the rendered figure in DPI. Defaults to 300.
 - `autoshow` *bool, optional* - Whether to show the resulting figure automatically. Defaults to True.
-- `original_time` *bool, optional* - Whether to plot original time or not. This parameter can be useful if the file has been shortened beforehand (e.g. skip). Defaults to False.
+- `original_time` *bool, optional* - Whether to plot original time or not. This parameter can be useful if the video file has been shortened beforehand (e.g. skip). Defaults to False.
 - `title` *str, optional* - Optionally add title to the figure. Possible to set the filename as the title using the string 'filename'. Defaults to None.
 - `target_name` *str, optional* - The name of the output image. Defaults to None (which assumes that the input filename with the suffix "_tempogram.png" should be used).
 - `overwrite` *bool, optional* - Whether to allow overwriting existing files or to automatically increment target filenames to avoid overwriting. Defaults to False.
