This is soem4thing that I doa lot this period for a weekly program I so with a buy from USA.
Let me be more practical and get immediately into the useful information :
I two programs form the far past he one is mP3 surgeon primarily used for trimming and cutting mp3 files ‘as a surgeon’ directly into the chunks instead of decompressing and recompressing the files that mans without any loss in audio quality. The program however has been stopped updating a lot ago ie around 2005 A few more utilities inside it mainly the joiner a mp3 into wav converter a batch , an mp3 catalog and a ID3 batch. A simple but professional program that requires 30Eu after the trial
The other program is nearly the same but much simpler : mp3trackmaker that cuts a long mp3 based in winamp’s relative positions in between songs with a separate tab for joining files. Is was a commercial program for very long time but more recently the developer offered it for free (as Irfanview older times )
Do you remember this program? Winano was a breakthrough audio fileplayer of the early times of mp3 period. This program reads the position df winamp and defines points where the file can be cut.
Both do the job very well but recently someone shown an old technique on how to use a DOS command to join files
Tis is something very simple
copy /b first-mp3-file.mp3 + second-mp3-file.mp3 merge.mp3
This can be easy to be made providing that you will join a few files What you can then? The bet way is to use one of the above programs Both programs can help you define the sequence of these files. Otherwise just dong the
Copy/b *.mp3 result.mp3 can copy the files in ‘random’
This is not exactly random as someone can think but there is a logic behind it: DOS system and Fat recognize the file position as added in the directory: first added first shown . The logic continues this way until a file is removed . The next added file will positioned in the vacant seat
As I noticed in his page
The unsorted files are made the way they are added in the directory Newer files are put into the bottom of the file directory If a file is deleted from this directory If you add a new file , it can be registered in the deleted files position I know that after experimenting a lot a few years ago. This also happens with your MP3 listing
Something important with file concatenation:
AS he poster ithe above page inisisted he could use the same technique with other file formats
For this reason I uses a very good audio converter and experimented sometime with various other formats with these results as below:
-FLAC AC3 play OK !
The resulted file is shown in the windows player with full length and both files are played
-OGG, AAC M4a , m4b , mp4 , wma v9 and wma10: Only the first file is played.
The poster also claims that he cold join .DOC and excel files . This is a big mistake . h ecan do that as far as the files are only text . However both todays’s DOC and XLS files are binary and compressed . I did that and understood that only the first if thse files can be shown!
To advise again if the files :
different bit rates they are played well
-If the first file is mono only and the second is stereo , the result will be mono only
-If the fist file is 44 kHZ and the second is 48000 only the first file will be heard. The remain flies will seem as VACANT!
