Mp3frame

This Utility analyzes, copies or modifies all frames of MPEG-1, MPEG-2 or MPEG-2.5 audio files compressed with Layer I, II or III.

Analysis

• general information, like length or ID3v1 tags
• detailed information about all frame headers (optional)
• summary information about the frame headers, like VBR or MS-stereo distribution
• frame consistency checks

Copy

• You may copy an entire file or parts of it to a new file.

Modification

• The gain (volume) may be modified. This is lossless. It is implemented by modifying all side info blocks or the scalefactors respectively of the file. This restricts the step size to 1.5 dB for layer III files and 2 dB for layer I and II files.
• Furthermore files may be stripped. This means that leading and trailing silence (empty frames) is removed.
• You may also use your own cut points by time or frame.
