Import Audio file to Unity

Unity supports importing audio files in the following formats:

Audio file type depends on your target if it is PC/Mac/Consoles or if it is mobile, for PC/Mac/Consoles Unity encodes the audio either as Ogg or Vorbis while for mobile it is MP3. To get the best sound quality, it is advisable to provide an uncompressed audio format in WAV or AIFF (containing PCM data) then leave Unity to do the encoding itself.

• .aif: Audio Interchange File Format
• .wav: Microsoft Wave - Game size issue might occur, as the main format for supplying uncompressed audio.
• .mp3: MPEG-1 Layer 3
• .ogg: Ogg Vorbis - Importing as OGG reduced the game's size by almost half. Even though Unity does the compression. learned from one of alumni, (CC Unity Professor) who work in game industry for a long time
  • Conver every file to OGG
• .xm: XM module
• .mod: Mod module
• .it: IT module
• .s3m: S3M module
• .flac: Free Lossless Audio Codec
