 |
|
Hi,
I was wondering if there's any kind of tool available that can convert the m4a files from sharpmusique (itunes) into mp3-files, so I can use the music I buyed on my mp3-player?
thnx

m4a -> wav
| Code: | | for i in *.m4a; do mplayer -ao pcm "$i" -aofile "$i.wav"; done |
wav -> mp3
| Code: | | for i in *.wav; do lame -h -b 192 "$i" "$i.mp3"; done |
strip down file extensions
| Code: | | for i in *.mp3; do x=`echo "$i"|sed -e 's/m4a.wav.mp3/mp3/'`; mv "$i" "$x"; done |
copied it somewhere, it worked for me.
regards |

Hi,
thanks for your reply...
I used it to build this script called m4a2mp3:
| Code: | #!/bin/bash
#
# Convert m4a to mp3
for i in $1/*.m4a
do
mplayer -ao pcm "$i" -aofile "$i.wav"
dest=`echo "$i.wav"|sed -e 's/m4a.wav$/mp3/'`
lame -h -b 192 "$i.wav" "$dest"
rm $i $i.wav
done |
I put this one /usr/local/bin and now I'm able to convert all m4a-files in the directory that I pass in the first parameter; so m4a2mp3 . for example will convert all the *.m4a files in the current working dir to mp3 and will clean up the source and temporary files. It will use as less diskspace as possible.
kind regards... |

| Why are you converting lossy --> lossy, why did you buy those files in the first place without a player for them? |

for those who find this thread useful in the future -aofile is depreciated in mplayer. now it is -ao pcm:file="filename"
so:
| Code: |
#!/bin/bash
#
# Convert m4a to mp3
for i in $1/*.m4a
do
mplayer -ao pcm "$i" -ao pcm:file="$i.wav"
dest=`echo "$i.wav"|sed -e 's/m4a.wav$/mp3/'`
lame -h -b 192 "$i.wav" "$dest"
rm $i $i.wav
done
|
or
| Code: |
for i in *.m4a; do mplayer -ao pcm "$i" -ao pcm:file="$i.wav"; done

Yes. iTunes uses pitiful bitrates, even the original file doesn't sound all that great.
I'd suggest buying real CDs (which cost about the same as 10-12 iTunes tracks) and then ripping them into the format of your choice. Vastly better sound quality, no DRM and a physical lossless backup copy. |

Yah I've already done that. The only problem is when I was still using Windows a few months ago, I used iTunes to rip a bunch of my cds. Now I want to play them in LINUX but amarok (taglib) doesn't have support for m4a yet.
I was going to convert the files... but I don't want them to be any worse than they are now. |

It will probably take just as much time to transcode the AAC tracks as would to re-rip the CDs. I really like Grip (http://nostatic.org/grip/) for CD ripping. |

Hi there
I got the same problem with mplayer so I replaced it by faad and fix a problem with filenames ("$i" instead of $i and so on)
| Code: | #!/bin/bash
#
# Convert m4a to mp3
for i in $1/*.m4a
do
faad -o "$i.wav" "$i"
dest=`echo "$i.wav"|sed -e 's/m4a.wav$/mp3/'`
lame -h -b 192 "$i.wav" "$dest"
rm "$i" "$i.wav"
done |
Probably you can reduce used disk space by deleting $i before using lame and then deleting $i.wav

Is there any way to transfer the audio tags by script as well? When I tried the script, the files I tested successfully transcode, but the tag info is not transfered (artist, title, track, albun, etc...) I am not veyr familiar with id3tag or other programs like that, but I am wondering if there is a better way than entering the data for my several thousand songs by hand...

Is there a way to convert mp3 to m4a on Linux?

here ya go
| Code: | #!/bin/bash
#
# Convert mp3 to m4a
for i in $1/*.mp3
do
mplayer -ao pcm "$i" -ao pcm:file="$i.wav"
dest=`echo "$i.wav"|sed -e 's/mp3.wav$/m4a/'`
faac -b 192 -o "$dest" "$i.wav"
rm "$i" "$i.wav"
done
|
i tested, didn't really play around with the faac encoder settings because i didn't have time to look them up...i don't know why you'd want it in m4a...
enjoy

Thanks I'll give that a shot. The only reason I want m4a is it takes up less space. I might just convert over to mp3 but I'm looking for a codec that has great quality and take up less space.

i'd give ogg a shot then. unless you need it on your ipod, then m4a and mp3 are your only options for now.
i find m4a support to be too shoddy. faad/faac didn't work properly on amd64 till recently, and muine, the audio player i use, doesn't import m4a despite its backend handling them, so i'm stuck with ogg and mp3 and flac for now. |

I installed it before but didn't like it. I just like how the original firmware is laid out.

Maybe try iPod Linux I have not tried it and I think I remember someone talking about OGG support on it, I don't have an iPod so I couldn't tell you. (I have an iAudio X5L w00t w00t  ) |

the problem with ipodlinux is that its not fully supported on most of the newer ipods.
i have a 4g, and i don't even think usb or firewire transfers are working on those yet... |
