mp3 patent expired in May 2017. Lame and ffmpeg are now part of Slackware-current (15.0 "real soon now"). ogg vorbis is OK, but for audio fidelity I prefer FLAC, lossless compression, unless I need to save space. Every linux distro on the planet and elsewhere can encode/decode flac. A few portable players have been adding it as well. TIP: iOS 11 added FLAC support. Most Android devices as well since 3.1. mp3 vs ogg: Compression rates are about the same. mp3 provides superior audio at higher bitrate (>128 kbps) and when using VBR encoding. opus/speex are good for VOIP applications, not so much for archival needs. audacity is my "go-to' for odd formats when I can't seem to figure out what WAV file a stupid cheap device generates. -Ed PS: BTW, you may have noticed this earlier, but ffmpeg has a complex command line, and your earlier ffmpeg post was in error. ffmpg <input options> -i <input file> <output options> <output file> e.g. https://trac.ffmpeg.org/wiki/Encode/MP3 The ffmpg an page can be hard to follow. the wiki has lots of good explanations and examples. Note that to support all formats ffmpeg can handle, appropriate adjustments to the buildscript are needed along with install a whole heck of a lot of codecs.
