Format of Choice for a Legal, Free, Audio-eBook?

audioAuthor asks: "Let's say I have a recorded audio-book (no music, just speech), which I want to share with the world. What format should I use to distribute it? Main requirements would be: 'Everyone is allowed to redistribute it without any restrictions" and "Usable as widely as possible'. I have been thinking of MP3, Ogg Vorbis and Speex. MP3 would be really nice, as it's usable almost everywhere, even without a computer, but it has licensing problems which I don't quite understand. Speex is free and designed for speech, but it's not widely supported at the moment. I think that Ogg Vorbis is currently better supported than Speex, and also free, but not designed for speech and would take more space to achieve same quality. So what do you say? Which one of these should I choose, or are there other formats to consider?"

  1. Why not all three? by zhiwenchong · · Score: 4, Insightful

    It isn't that hard to release an audio book in all 3 formats.

      I agree with zhiwenchong, the people who make mp3 encoders are the ones who have to pay a license currently (how LAME gets around it is little complex, but not your problem in any case), not content creators so there is no reason not to make an mp3 version. If you have software to create ogg vorbis and speex files you might as well go ahead and do it for anyone who would prefer them. The speex file may save some bandwith and the ogg vorbis file just gives you that warm free software feeling. Hope your project goes well.

  2. What is your *real* goal? by hoggoth · · Score: 4, Insightful

    Simple.
    If you want to make a political/philosophical statement use Ogg Vorbis.
    If you want no-one to ever bother listening to it use Speex.
    If you want many people to listen to it use MP3.

  3. Licensing? by general_re · · Score: 4, Informative

    As a noncommercial end-user, MP3 licensing is not a problem for you. If you were developing software to implement MP3, either encoding or decoding, or your MP3-encoded content were part of a commercial (i.e., revenue generating) enterprise, then you would need a license. Since neither of those apply, MP3 is free for you to use.

  5. Re:All of them by munpfazy · · Score: 2, Insightful

    Yup. "All of them" is the way to go.

    MP3 is ubiquitous and great for almost any portable player. The only reason not to use it is because you like some other format and want to forcibly promote it. (Which assumes that your audience knows your work well enough to consider installing new software in order to hear you... which may or may not be true.) At least when using LAME, you can fine tune the compressing for the speaker to reduce file size pretty considerably.

    Ogg vorbis is great for both philosophical and practical reasons, but you'll limit your audience since only a few portable player companies include support for it. If your background is quiet, you can really crank up the compression on a speach-only vorbis file before noticeably impacting quality.

    Never used the speex, but there's no harm in offering it. Chances are few will use it.

  6. Re:LAME and MP3 by Anonymous Coward · · Score: 2, Informative

    Entirely misinformation.
    (A) The (L)GPL patent clause doesn't make any distinction between commercial use or not.
    (B) LAME is not Free Software in any country that respects MP3 patents -- it's actually illegal to distribute according to the LGPL licence in places like the US and Germany.
    (C) If someone does illegally distribute LAME to you, Fraunhofer will still want their damn money.

  7. FLAC by Jebediah21 · · Score: 2, Informative

    FLAC can be converted into whatever format the user wants. Considering it's speech you should get around 50% compression from the wavs. Of course not everybody will want to download that so put it in mp3 too. I can't think of anything that plays Ogg and not mp3. Speex is not that widespread at this point, so if anybody really wants it they can convert from FLAC. And that's the beauty of FLAC too. Some new format gets popular you can convert it into that too.

    Incidently, if you are a pure pragmatist and don't mind using a closed proprietory codec, Microsoft's Voice 9 codec (IIRC) gives very good quality at a low bit-rate, and probably over 98% of users will be able to play it back without installing any new software. (The encoder is a free download from Microsoft.)
