VisMP3 is an alternative to the MP3 music player on the PSP.

It offers some important features namely a media library that organizes mp3s (regardless of folder setup) as well as playlist functionality. Also as indicated by the name, VisMP3 demonstrates several different types of visualizations for a visual as well as audio experience (e.g. Fireworks visulization).

It was one of the contest entries for the NEO Spring Coding Compo 2008 (PSP App).

Features

• Automatic detection of MP3 files in a folder and its subfolders (specified in config).
• Hardware decoding of MP3 files.
• Parsing of ID3v1 and ID3v2 information used to build media library.
• Media Library accessed through Artist, Album, and Genre categories.
• Creation of playlists from media library items, easy to add full albums or single songs.
• Playlists are number 0-98 and can save/load from the program.
• Skinnable (background image and UI colors chosen while running).
• Supports Sony remote control for playback control.
• Smart Random (no repeats) and Linear playback of playlists.
• 4 different visualizers, all with runtime adjustable properties.
• Allows background visualizations while navigating media library, playlist, etc.
• Font support for loading pgfs (not available to the user yet, but uses system fonts to look nice).
• Also supports simple bitmap style font for faster rendering.

User guide

Visualizers

You can choose between 4 different visualizers:

• Spectrum Analyzer.
• Boom Box (boxes flying across the screen with visually stimulating thumps).
• Fireworks.
• Oscilloscope-style view of sample data.

Play around with the visualization settings, especially for the fireworks. It has lots of adjustable properties.

Media library

If you have MP3's anywhere under ms0:/MUSIC/, they should be automatically parsed when the program starts. You will see progress of MP3 loading.

If your media is a different directory, run the program once and a config.ini file will be created. Change the media directory property to your desired directory (but not any others) and it should work.

If you add new media to your media folder (defaults to ms0:/MUSIC/), then you will need to go to the properties page for library and rescan in order to recreate the media library.

Settings

Rather than saving your properties each time you fiddle with them, you can opt to disable the prompt to save and save you properties manually through the system options menu instead. You can also load your last saved properties here as well.

If you have deleted any of the system fonts (including jpn0.pgf) from your flash0, you may experience problems with the text (jpn0.pgf, ltn0 and ltn8.pgf were used for text rendering).

You can load up a background image (must be PNG, 480 x 272) to show behind everything else that is drawn, located in the Theme properties page.

The time that the text fades out in is controlled in the System menu. This can be useful if you want to watch visualizations without having to wait forever for the text to disappear.

If you want a visualization to be active when it isn't selected in the list, choose it's properties and enable it to be always on. Be careful though, too many fireworks can slow down the framerate if you are not careful about the settings.
