Supported Audio Formats and File Quality

When using the Phorus app, which is powered by Play-Fi, it streams audio directly from source devices to the speakers and supports a wide variety of streaming formats and audio quality levels.

Supported File Formats

  • .mp3 (MPEG Layer III)
  • .m4a and .aac (Advanced Audio Coding)
  • .flac (Free Lossless Audio Codec)
  • .wav (Waveform Audio File)

File Quality

  • Up to 24-bit/192kHz.  (High resolution)

Files up to 16-bit/48 kHz (CD Quality) are streamed with bit-for-bit accuracy, with zero compression or transcoding.  With high resolution files, Play-Fi down-samples the audio to CD quality (16-bit/48kHz) for transmission.  This allows for the most reliable streaming experience over Wi-Fi to multiple speakers.
