Likewise, if the\noutput file is \"-\", data is written to stdout if one of streamable AAC\ntransport formats are selected by **-f**.\n\nWhen CAF input and M4A output is used, tags in CAF file are copied into\nthe resulting M4A.\n\nOPTIONS\n=======\n\n-h, --help\n:   Show command help\n\n-o \\\u003cFILE\\\u003e\n:   Output filename.\n\n-p, --profile \\\u003cn\\\u003e\n:   Target profile (MPEG4 audio object type, AOT)\n\n    2\n    :   MPEG-4 AAC LC (default)\n\n    5\n    :   MPEG-4 HE-AAC (SBR)\n\n    29\n    :   MPEG-4 HE-AAC v2 (SBR+PS)\n\n    23\n    :   MPEG-4 AAC LD\n\n    39\n    :   MPEG-4 AAC ELD\n\n-b, --bitrate \\\u003cn\\\u003e\n:   Target bitrate (for CBR)\n\n-m, --bitrate-mode \\\u003cn\\\u003e\n:   Bitrate configuration mode. Available VBR quality value depends on\n    other parameters such as profile, sample rate, or number of\n    channels.\n\n    0\n    :   CBR (default)\n\n    1-5\n    :   VBR (higher value -\\\u003e higher bitrate)\n\n-w, --bandwidth \\\u003cn\\\u003e\n:   Frequency bandwidth (lowpass cut-off frequency) in Hz. Available on\n    AAC LC only.\n\n-a, --afterburner \\\u003cn\\\u003e\n:   Configure afterburner mode. When enabled, quality is increased at\n    the expense of additional computational workload.\n\n    0\n    :   Off\n\n    1\n    :   On (default)\n\n-L, --lowdelay-sbr \\\u003cn\\\u003e\n:   Configure SBR activity on AAC ELD.\n\n    -1\n    :   Use ELD SBR auto configuration\n\n    0\n    :   Disable SBR on ELD (default)\n\n    1\n    :   Enable SBR on ELD\n\n-s, --sbr-ratio \\\u003cn\\\u003e\n:   Controls activation of downsampled SBR.\n\n    0\n    :   Use lib default (default)\n\n    1\n    :   Use downsampled SBR (default for ELD+SBR)\n\n    2\n    :   Use dual-rate SBR (default for HE-AAC)\n\n    Dual-rate SBR is what is normally used for HE-",
