Spider Player 2.1 is a major update which brings some very nice enhancements to the converting features.

New features highlights: 

• More converting options and new user interface for them.
• Encreased converting speed.
• Support for encoding to FLAC and WavPack makes Spider Player ideal for ripping CDs to
  one of these lossless formats for your personal music collection and then quickly converting to
  MP3 or AAC when needed to use with your portable MP3 player.
• Support for custom encoders allows to use any external command-line encoder with STDIN support with Spider Player.
  Presets for some popular encoders, such as Nero Digital Audio Encoder, FAAC, Musepack and Lame are included.
  
• New Import/Export feature of the Preset Manager allows to backup or share your equalizer and encoding presets with friends or other users easily.
