The software enables visualization of power levels in every MP3 file frame, among other features.
I recently used this program to cut out unwanted frames from an MP3 file and I must say, it was a life-saver. Visualising power levels in each frame is a unique feature that set this program apart from others. Selecting a region and removing unwanted frames was a breeze. What's more, the selected frames (minus the cuts) could be easily saved in a new MP3 file.
One thing to keep in mind: the first frame in the selection will be incomplete if the input MP3 stream uses the bit reservoir (which is the case for most files), and may cause playback issues. However, this can be avoided by turning off the bit reservoir when encoding.
This was my first GUI program and I tested it on FreeBSD 3.x and Mandrake Linux 6.0. Installing the program requires GTK+ 1.2, Autoconf, Automake, GNU Make, and mpg123 to play a selection.
Upon launching the program, a window with a white rectangle appears to display the frame power levels. You can open an MP3 file either by naming it on the command-line, or by using File->Open in the drop-down menus. After opening the file, a plot of frame power vs frame number is displayed. You can use the mouse to select a region, which will be displayed in red, and click-drag to add/remove to the selection.
A marker can be set with a single middle-click that appears as a vertical blue line. You can then perform a middle-button mouse drag to set the start and endpoint of a selection.
To remove unwanted frames, you can use the `c' key to 'cut out' the selected area. These frames will appear greyed out but will not be played or saved to the new MP3 file. The `r' key can be used to remove all cuts made and Ctrl-Z can be used to undo the last cut.
Overall, this program is highly recommended for its unique feature of visualising frame power levels and easy editing of MP3 files. The recent update has also added the much-needed Ctrl-Z function to undo the last cut, along with a bug fix for cuts being cleared when a file is opened.
