    What is the best possible audio quality (bitrate, format, etc...) combination out there?

    I usually keep all my music MP3's at 192 Kb

    If you are talking mp3's the best is 320 kbps. For almost as good sounding (and much smaller file size) use VBR (variable bit rate). The old Lame -alt -preset -standard was VBR 128 kbps to 320 kbps, and joint stereo with a few more tweaks. It had a file size about the same as a CBR 192 kbps but sounded better than even a 224 CBR (much larger file).

    If you want 'best possible audio quality' then you don't compress the audio at all and use .wav files. The problem is they take up a lot of disk space. If you want portability, then you probably want to go with mp3's which can be played on the most portable player's. It depends on what you want to do with your music.

    There are lossless compression formats out there and they produce file sizes significantly smaller than WAV, sometimes half the size, with FLAC and Monkey's being popular.

    * Apple Lossless - ALAC (Apple Lossless Audio Codec)
    * Direct Stream Transfer - DST
    * Free Lossless Audio Codec - FLAC
    * Meridian Lossless Packing - MLP
    * Monkey's Audio - Monkey's Audio APE
    * RealPlayer - RealAudio Lossless
    * Shorten - SHN
    * TTA - True Audio Lossless
    * WavPack - WavPack lossless

    There are codecs that claim lossless compression. If you open WMP and go to tools>rip music Under the format you have a choice, If you select Windows Media Lossless this will give you about 2:1 to 3:1 compression compared to WAV. The files ares still big and unless your an audiophile with a really good system you probably won't hear the difference between that and high bitrate MP3 or regualr WMA file.

    There's other too, I've seen FLAC mentioned too. http://flac.sourceforge.net/index.html

    It's not a "claim" as you put it, there are truly lossless codecs.

    Actually, since even Lossless codecs are still sample based, they aren't the truely best quality you can get.

    The best quality will be records (LPs), because they are analog (hence an infinite number of samples).

    So you are saying the poster should convert his stuff to LP's ? :rolleyes: A fascinating and utterly useless nugget of information.

    According to the Nyquist-Shannon theorem as long as the sampling rate is twice that of the highest frequency in the sampled audio, there is no quality loss due simply to quantising an analog signal to a digital one.If LPs sound better than Digital it has nothing to do with the fact that that digital audio is stored as discrete signals.

    As for the original question if you have the storage space, go with a lossless codec (FLAC is the most widely used and has the best Hardware support), if you want to save disk space MPC is widely regarded as the best Lossless codec at high bit rates e.g 320.

    WMA lossless is the simplest to use. Plus, no need for additional codecs or software for windows media players.

    Ape offers the best compression ratio. Though not by much.

    Flac offers open source, good support.

    Don't think you'll be able to tell the sound difference in any of them, if there is any.

    Well WMA is Microsoft who claims their regular compression sounds better than MP3, when in fact in blind listening tests LAME mp3's alway win out.

    It's very important to support the "other guys" as this is what moves the whole industry. People now are looking at the new and "improved" IE7, it's FireFox that got MS off it's duff. If it wasn't for AMD we would still be running 1000MHz Intel boxes that would cost about $2000.

    If anyone is interested in Open Source (free) software to try here's a very comprehensive list with many great apps.

    I suspect that would only be true if the entire recording path from microphones and instrument pickups through LP mastering was all analog. What you gained by infinite sample rates would most likely be lost by added noise such as tape hiss.

    I would not be surprised if most recent vinyl LP production included digitized audio somewhere in the production path. Didn't some musical instrument company come up with an electric guitar with a specialized Ethernet output?

    EDIT: To answer my own question:
    Yes, the company is Gibson.

    FLAC would be the most reasonable, quality space saving format, IMHO.
