    Default Convert Flac to m4a

    I'm thinking of converting all my flac files to apple lossless m4a, maybe that file is better supported in Traktor pro regarding the storage of the traktor data in the file itself rather than in traktor itself...

    Anybody got any info on this?

    Also i know converting is always loosing a bit of quality, but since this are lossless compressions... is there any quality lost then?
    I would think not, isn't it just the same as a data file going from zip to rar ?

    I use Switch for converting, it's handy and does the job quite well: http://www.nch.com.au/switch/

    My alltime favorite is "dBpoweramp Music Converter". You can choose the plugin codecs you want from their site.
    It integrates into the shell of windows so i can rightclick the file i want to convert, even supports multicore !

    In theory, going from FLAC to m4a should yeild a file that would could be converted back to .wav and be identical to the original file. If you have doubts, you could always go from flac to wav to m4a, checking each step, but I have enough trust in technology that the conversion would go right. Plus, that would take forever on a big library.

    I would also like to know which is supported better in TPro. I like the fact that with m4a I can dump the same songs right on my Iphone without worrying about the FLAC to Mp3 conversion and doubles. Anybody know about Tpro and m4a's?


    more comparisons of lossless codecs can be found here http://wiki.hydrogenaudio.org/index....ess_comparison

    i dont think m4a support is any better than flac support to be perfectly honest
    Edit: we should make up a breakdown list of the functionality that different files offer, that would put all this strait !

    Great idead Bento.

    Slightly OT: m4a and FLAC don't use ID3v2 tagging. Having said that, has anybody really seen the ID3v2 standard and what it's capable of? A few exerpts from the standard taken from www.id3.org. Keep in mind, this is already implemented as a standard available to anyone who can read, including Native Instruments and Ableton.

    -Musical Events(can anybody say Hotcues or Clean/Explicit songs with only 1 file by bleeping/reversing during the event). This frame allows synchronisation with key events in the audio. The type of event is as follows:

    $00 padding (has no meaning)
    $01 end of initial silence
    $02 intro start
    $03 main part start
    $04 outro start
    $05 outro end
    $06 verse start
    $07 refrain start
    $08 interlude start
    $09 theme start
    $0A variation start
    $0B key change
    $0C time change
    $0D momentary unwanted noise (Snap, Crackle & Pop)
    $0E sustained noise
    $0F sustained noise end
    $10 intro end
    $11 main part end
    $12 verse end
    $13 refrain end
    $14 theme end
    $15 profanity
    $16 profanity end

    -Synchronised tempo codes (beat grids that would be stored in a common format, available to all DJ programs, maybe even released to the public with the beatgrids already established)

    For a more accurate description of the tempo of a musical piece, this
    frame might be used. After the header follows one byte describing
    which time stamp format should be used. Then follows one or more
    tempo codes. Each tempo code consists of one tempo part and one time
    part. The tempo is in BPM described with one or two bytes. If the
    first byte has the value $FF, one more byte follows, which is added
    to the first giving a range from 2 - 510 BPM, since $00 and $01 is
    reserved. $00 is used to describe a beat-free time period, which is
    not the same as a music-free time period. $01 is used to indicate one
    single beat-stroke followed by a beat-free period.

    The tempo descriptor is followed by a time stamp. Every time the
    tempo in the music changes, a tempo descriptor may indicate this for
    the player. All tempo descriptors MUST be sorted in chronological
    order. The first beat-stroke in a time-period is at the same time as
    the beat description occurs. There may only be one "SYTC" frame in
    each tag.

    -Synchronised lyrics/text (VJ'ing/Karaoke made easy, without buying new songs)

    This is another way of incorporating the words, said or sung lyrics,
    in the audio file as text, this time, however, in sync with the
    audio. It might also be used to describing events e.g. occurring on a
    stage or on the screen in sync with the audio. The header includes a
    content descriptor, represented with as terminated text string. If no
    descriptor is entered, 'Content descriptor' is $00 (00) only.


    These are just 3 I beleive have potiential.

    Jaikoz supports and shows all data that is in the tags themselves, even for Apple Lossless, so tonight I will do some searching and see if the data is stored in the file itself or inside Traktor.

    I'm a fan of Format Factory:

    http://www.formatoz.com/download.html

    It does most audio formats and most video to. I've had good luck with it converting divx to a format for my psp.
