• AAC_XHE_MAX_RATE_BYTES_PER_SECOND

  public static final int AAC_XHE_MAX_RATE_BYTES_PER_SECOND

  Deprecated.
  Maximum rate for an AAC XHE audio stream, in bytes per second.

  Fraunhofer documentation says "500 kbit/s and above" for stereo, so we use a rate generously above the 500 kbit/s level.
