- Usage:
- neroAacEnc [options] -if <input-file> -of <output-file>
- Where:
- <input-file> : Path to source file to encode.
- The file must be in Microsoft WAV format and contain PCM data.
- Specify - to encode from stdin.
- <output-file> : Path to output file to encode to, in MP4 format.
- ==== Available options: ====
- Quality/bitrate control:
- -q <number> : Enables "target quality" mode.
- <number> is a floating-point number in 0...1 range.
- -br <number> : Specifies "target bitrate" mode.
- <number> is target bitrate in bits per second.
- -cbr <number> : Specifies "target bitrate (streaming)" mode.
- <number> is target bitrate in bits per second.
- When neither of above quality/bitrate options is used,
- the encoder defaults to equivalent of -q 0.5
- Multipass encoding:
- -2pass : Enables two-pass encoding mode.
- Note that two-pass more requires a physical file as input,
- rather than stdin.
- -2passperiod : Overrides two-pass encoding bitrate averaging period,
- <number> : in milliseconds.
- : Specify zero to use least restrictive value possible (default).
- Advanced features / troubleshooting:
- -lc : Forces use of LC AAC profile (HE features disabled)
- -he : Forces use of HE AAC profile (HEv2 features disabled)
- -hev2 : Forces use of HEv2 AAC profile
- Note that the above switches (-lc, -he, -hev2) should not be
- used; optimal AAC profile is automatically determined from
- quality/bitrate settings when no override is specified.
- -ignorelength : Ignores length signaled by WAV headers of input file.
- Useful for certain frontends using stdin.
