    Hello, I need info to stream my radio station in MP2.

    Anyone know more about this topic?

    PD: Forget AudioTX, is very expensive 🙂

    There used to be an MP2 compatible codec called tooLame. Maybe this will work in something like Edcast, otherwise, there are very few options as MP2 is not widely used, less efficient tha MP3 and expensive to licence.

    And oh my god how horrible MP2 @ 128kbps sounds like, how can that be used as a STL like many stations do!

    Thanks for the info, I found the page of twolame, but the DLL is not compiled for Windows. You have this DLL for me?

    Thanks!

    toolame: http://www.rarewares.org/files/mp3/tooLAME0.2l.zip

    .. but there is a another encoder, called "twolame", documentation here: http://www.twolame.org/
    DLL here: http://www.rarewares.org/files/mp3/twolame0.3.13.zip

    Thanks, but the 2 files are EXE’s, I need the DLL to include in Edcast.

    I need stream in real-time with MP2 compression.

    Any idea?

    Thanks ! ! !

    For any kind of quality in layer-2, you’re looking at above 400 kbps.

    I try with 192 and 256 kbps with AudioTX and the sound it’s OK.

    I need emulate the sound of big radio stations (that uses this compression)

    Thanks!

    I have never heard MP2 sound OK at 256kbps, at least not if you run a processor after. 384 sounds good.

    Different people may have different opinions as to what’s OK. My tolerance for distortion and compression artifacts is very low.

    Sorry, I like the compression artefacts of MP2… hehehe 😆 😆 😆

    Agreed with Leif on rates: 384 is excellent (very few ears on this planet could tell it from PCM), anything lower is noticeable to my ears, and probably others.

    Another poster mention prohibitive licensing costs. That is not correct. Layer II is free for your use. It gets confusing because MP3 is the version that cannot be used without Fraunhofer runtime codec licensing (which is included in some professional codec products, like Omnia AX/E).

    Hope this helps.

    Wow.. AudioTX is $799?? For a point to point streaming tool??

    Looks like I’m in the wrong business!! I’ve spent years developing audio processing — if I would have just made a streaming tool instead, I could have done it in days, and been rich! 🙄

    I’ll make an vorbis based replacement. This is just shameful.

    For those not familiar with it, Vorbis is comparable in quality to AAC, and much better than MP3 — and it’s open source/free.

    For those familiar with it, I’m saying "Vorbis" as opposed to "Ogg Vorbis" because I don’t intend to use the Ogg part. 🙂

    A good yet economical program of this type is what we have been crying out for, for years and even AudioTX is not perfect. I’d be interested to see/evaluate anything you can come up with.

    Yorkie.
