Save wav file

Saves object to a wav file by converting to the wave representation and then writing to a wav file.

save_wav(
  x,
  file,
  amplitude = 0.1,
  bit_depth = 16L,
  length_sec = 1,
  fade_length = 0.1,
  rise_length = 0.1,
  end_pad = 0.05,
  ...
)

`x`	Object to save; currently only individual chords are supported. Chords are coerced to a `wave` representation.
`file`	(Character scalar) Output file.
`amplitude`	(Numeric scalar) The wave is multiplied by this number before exporting. The resulting wave should fall completely within the range [-1, 1].
`bit_depth`	(Integer scalar) The bit depth of the exported audio.
`length_sec`	(Numeric scalar) Length of the output wave, in seconds.
`fade_length`	(Numeric scalar) Chord fade-out time (seconds).
`rise_length`	(Numeric scalar) Chord fade-in time (seconds).
`end_pad`	(Numeric scalar) Duration of silence (seconds) appended to the end of the audio file, used to avoid clicks and other artifacts.
`...`	Arguments passed on to `expand_harmonics` `num_harmonics` (Integerish scalar) Number of harmonics (including the fundamental) to which each tone should be expanded. `roll_off` (Numeric scalar) Parametrises the amount of amplitude roll-off in the harmonics, with greater values corresponding to higher roll-off. `digits` Number of digits to which each partial's MIDI pitch should be rounded. `label_harmonics` If TRUE, then the harmonics in the resulting spectrum are labelled with their harmonic numbers. `coherent` Whether the amplitudes from different spectral components should be combined assuming coherent summation, where the amplitudes simply add together (default is `FALSE`). Otherwise incoherent summation is used, where the amplitudes are squared, added, then square rooted.
