Software We Use

From Librivox wiki
Jump to navigationJump to search

This page lists software used or recommended by our volunteers. Here you will find programs to record, edit, or playback audio. There are also encoders, ID3 tag editors, and more. Many of these programs do more than one of these tasks. If you know of related software that would be useful, please let us know.

Comparison Chart

Please notice this table is based on what LibriVox volunteers know about these programs, so it is certainly incomplete and, in part, based on opinion.

Chart Legend

Feature list
Mac = Apple Macintosh.
Win = MS Windows.
Lin = Linux
Rec. = program can record
Playbk = program can play back
MP3 = program can encode to MP3 format.
ID3 = program is or has an ID3 tag editor.
rip = program can extract, or rip, tracks from audio CDs.
burn = program can write, or burn, audio CDs.

Feature indicators
Y = feature is available.
- = feature available in test/experimental version.
- = feature not available.
Under cost, the number of dollar signs ('$') indicates the relative price, 0 = free, and 0$ = comes in both free and pay versions (pay versions have more features).

Under playback, most letters indicate formats:
W = Wave, A = AAIF, M = MP3, C = audio CDs, Y = too many to list.

Under MP3, E = with user-installed encoder (straightforward to do).

A letter in bold face indicates the program excels at or is primarily designed to do that task (but that doesn't mean other programs with the same feature which are not bold are bad at that task).

A blank cell generally means "we don't know".

These applications were recommended on Slashdot as being free of spyware/adware ... but, of course, you have to be the final judge.
