Element encoding raw audio into MPEG-1, layer 3 format

Element options

Passed via struct Membrane.MP3.Lame.Encoder.t/0

• gapless_flush

  boolean()

  Default value: true
  When this option is set to true, encoder will be flushed without outputting any tags and allowing to play such file gaplessly if concatenated with another file.

• bitrate

  integer()

  Default value: 192
  Output bitrate of encoded stream in kbit/sec.

• quality

  non_neg_integer()

  Default value: 5
  Value of this parameter affects quality by selecting one of the algorithms for encoding: 0 being best (and very slow) and 9 being worst.

  Recommended values:

  • 2 - near-best quality, not too slow
  • 5 - good quality, fast
  • 7 - ok quality, really fast
