使い方

簡単な使い方のみです。vorbiscomment.exeの使い方はまだありません。

oggenc

Wav形式からOGG形式を作成します。

簡単な使用例

oggenc input.wav

同じ階層にinput.oggが作成されます。

出力を指定

-o　オプションを使用します。

oggenc -o output.ogg input.wav

指定したパスで出力されます。

品質を指定

bitrateでの指定もできますが、入力Wav形式のsamplerateやchannelにより可能な範囲が異なるので

0(最低)から10(最高)の品質を指定します。

-q　オプションを使用します。

oggenc -q 10 input.wav

音声形式を変換

通常は、入力音源と同じサンプリングレート、チャンネルで変換されますが

指定することも可能です。

--resample --downmix オプションを使用します。(チャンネルはステレオからモノラルへの変換のみ)

oggenc --resample 11025 --downmix input.wav

サンプルレートが11025、チャンネルがモノラルでエンコードされます。

oggdec

OGGファイルをWave形式に変換します。

RAW PCM出力や、samplebitを指定することも可能です。

簡単な使用例

oggdec input.ogg

同じ階層にinput.wavが作成されます。

出力を指定

-o　オプションを使用します。

oggdec -o output.wav input.ogg

指定したパスで出力されます。

vcut

OGGファイルを２つに分割します。

数字のみの場合はsample数で指定、+の後の数字の場合は秒単位で指定します。

最小単位があるみたいですが、不明です。小数点は使えません。

２回分割すれば、抜き出しもできそうな気もします。

使用例

vcut C:\tmp\En-us-lunar.ogg before.ogg after.ogg +1000

１秒の所で２つに分割

ogginfo

OGGファイルの情報を取得します。コメントなども見れます。

使用例

ogginfo C:\tmp\En-us-lunar.ogg

出力結果

Processing file "C:\tmp\En-us-lunar.ogg"...

oggenc

OggEnc v1.0.1 (libvorbis 1.0.1)
(c) 2000-2003 Michael Smith <msmith@xiph.org>

Usage: oggenc [options] input.wav [...]

OPTIONS:
 General:
 -Q, --quiet          Produce no output to stderr
 -h, --help           Print this help text
 -r, --raw            Raw mode. Input files are read directly as PCM data
 -B, --raw-bits=n     Set bits/sample for raw input. Default is 16
 -C, --raw-chan=n     Set number of channels for raw input. Default is 2
 -R, --raw-rate=n     Set samples/sec for raw input. Default is 44100
 --raw-endianness     1 for bigendian, 0 for little (defaults to 0)
 -b, --bitrate        Choose a nominal bitrate to encode at. Attempt
                      to encode at a bitrate averaging this. Takes an
                      argument in kbps. This uses the bitrate management
                      engine, and is not recommended for most users.
                      See -q, --quality for a better alternative.
 -m, --min-bitrate    Specify a minimum bitrate (in kbps). Useful for
                      encoding for a fixed-size channel.
 -M, --max-bitrate    Specify a maximum bitrate in kbps. Useful for
                      streaming applications.
 -q, --quality        Specify quality between 0 (low) and 10 (high),
                      instead of specifying a particular bitrate.
                      This is the normal mode of operation.
                      Fractional qualities (e.g. 2.75) are permitted
                      Quality -1 is also possible, but may not be of
                      acceptable quality.
 --resample n         Resample input data to sampling rate n (Hz)
 --downmix            Downmix stereo to mono. Only allowed on stereo
                      input.
 -s, --serial         Specify a serial number for the stream. If encoding
                      multiple files, this will be incremented for each
                      stream after the first.
 --discard-comments   Prevents comments in FLAC and Ogg FLAC files from
                      being copied to the output Ogg Vorbis file.

 Naming:
 -o, --output=fn      Write file to fn (only valid in single-file mode)
 -n, --names=string   Produce filenames as this string, with %a, %t, %l,
                      %n, %d replaced by artist, title, album, track number,
                      and date, respectively (see below for specifying these).
                      %% gives a literal %.
 -X, --name-remove=s  Remove the specified characters from parameters to the
                      -n format string. Useful to ensure legal filenames.
 -P, --name-replace=s Replace characters removed by --name-remove with the
                      characters specified. If this string is shorter than the
                      --name-remove list or is not specified, the extra
                      characters are just removed.
                      Default settings for the above two arguments are platform
                      specific.
 -c, --comment=c      Add the given string as an extra comment. This may be
                      used multiple times. The argument should be in the
                      format "tag=value".
 -d, --date           Date for track (usually date of performance)
 -N, --tracknum       Track number for this track
 -t, --title          Title for this track
 -l, --album          Name of album
 -a, --artist         Name of artist
 -G, --genre          Genre of track
                      If multiple input files are given, then multiple
                      instances of the previous five arguments will be used,
                      in the order they are given. If fewer titles are
                      specified than files, OggEnc will print a warning, and
                      reuse the final one for the remaining files. If fewer
                      track numbers are given, the remaining files will be
                      unnumbered. For the others, the final tag will be reused
                      for all others without warning (so you can specify a date
                      once, for example, and have it used for all the files)

INPUT FILES:
 OggEnc input files must currently be 24, 16, or 8 bit PCM WAV, AIFF, or AIFF/C
 files, 32 bit IEEE floating point WAV, and optionally FLAC or Ogg FLAC. Files
  may be mono or stereo (or more channels) and any sample rate.
 Alternatively, the --raw option may be used to use a raw PCM data file, which
 must be 16 bit stereo little-endian PCM ('headerless wav'), unless additional
 parameters for raw mode are specified.
 You can specify taking the file from stdin by using - as the input filename.
 In this mode, output is to stdout unless an output filename is specified
 with -o

ogginfo

Usage: ogginfo [flags] file1.ogg [file2.ogg ... fileN.ogg]

Ogginfo is a tool for printing information about ogg files
and for diagnosing problems with them.
Full help shown with "ogginfo -h".

vcut

Usage: vcut infile.ogg outfile1.ogg outfile2.ogg [cutpoint | +cutpoint]

vorbiscomment

Usage: 
  vorbiscomment [-l] file.ogg (to list the comments)
  vorbiscomment -a in.ogg out.ogg (to append comments)
  vorbiscomment -w in.ogg out.ogg (to modify comments)
	in the write case, a new set of comments in the form
	'TAG=value' is expected on stdin. This set will
	completely replace the existing set.
   Either of -a and -w can take only a single filename,
   in which case a temporary file will be used.
   -c can be used to take comments from a specified file
   instead of stdin.
   Example: vorbiscomment -a in.ogg -c comments.txt
   will append the comments in comments.txt to in.ogg
   Finally, you may specify any number of tags to add on
   the command line using the -t option. e.g.
   vorbiscomment -a in.ogg -t "ARTIST=Some Guy" -t "TITLE=A Title"
   (note that when using this, reading comments from the comment
   file or stdin is disabled)
   Raw mode (--raw, -R) will read and write comments in utf8,
   rather than converting to the user's character set. This is
   useful for using vorbiscomment in scripts. However, this is
   not sufficient for general round-tripping of comments in all
   cases.
