• Audio file chopper wanted

    From Don Pearce@21:1/5 to All on Tue Aug 24 10:57:04 2021
    I like to listen to audio books during long car journeys, but my MP3
    player refuses to play long files. An audio book is typically two to
    three hours long. At the moment I am laboriously editing the files
    into pieces, but there has to be a better way - many people must have
    wanted to do this.
    So I need some software that will take a large MP3, chop it into - say
    - five minute segments, then save them sequentially as 01.MP3, 02.MP3
    etc which my car player can make sense of and play them out in the
    right order.
    Does anyone know of such an app? A batch script for Adobe Audition
    would, I suppose be an alternative, but I have no idea how that would
    work either.

    Thanks. I wasn't aware of this, but it doesn't seem to add anything to
    my current method of selecting five minutes, hitting "Save Selection
    As" to get my sequential file number, then deleting the selection from
    the original. Rinse and repeat to end. That is the process I would
    like to automate.

    Have you tried the "Silence Finder" to create label/split points? After
    the split, maybe the export function will create default names for the
    tracks.

    My experience is limited to trying to create tracks for album-length
    files which I did without knowing about the silence finder.

    This looks like it will do it (windows):

    https://www.nch.com.au/splitter/index.html

    apparently sox can do this on the command line,
    (Windows, Linux, Max) which is going to be the
    best in the end.

    http://sox.sourceforge.net/

    From the manual:

    The following is an example of multiple effects chains. It will split the input file into multiple files of 30 seconds in length. Each output filename will have unique number in its
    name as documented in the Output Files section.
    sox infile.wav output.wav trim 0 30 : newfile : restart

    What you want is called an MP3 Cutter. There are a bunch out there.
    The idea here is that you don't want to decode and re-encode the mp3
    file... you just want to find the nearest frame boundary and cut there.
    This is no good for precise edits but you don't need precise edits,
    you just want simple cutting.

    MP3DirectCut
    Lossless MP3 editor that can do what you want: http://mpesch3.de/
    it doesn't decode and reencode your MP3 files, all the software
    that does have to decode and reencode will cause quality
    degradation.

    If you don't mind some loss of quality though decoding
    en re-encoding you can use that, but for Windows (and Android)
    Mp3DirectCut appears to be the only free direct MP3/AAC editor
    that cause no quality loss whatsoever because it does not
    decode and re-encode you files.

    Thanks, but quality loss is really not an issue. These things are not
    great before I even start, and they are only speech to be heard in a
    car - not the most discerning environment.
