karlo 0 Report post Posted June 25, 2005 Hello... You all like to download MP3's online right? Well, hmmm... i love to download them and burn them in a cd but there's some unanswered questions roaving in my mind. Example, I have many duplicates of one song with different file names, well, I want to remove those duplicate ones... how? And MP3 is compressed right? Is there a way to uncompress those compressed sound so that I will really do unlock the wonderful sound of the audio? Share this post Link to post Share on other sites
miCRoSCoPiC^eaRthLinG 0 Report post Posted June 25, 2005 Example, I have many duplicates of one song with different file names, well, I want to remove those duplicate ones... how?There surely are some file-comparison programs which can match up files with similar sizes and then analyze the content a bit to tell whether they are the same or not - although am not sure of their names. This can very well be done with a checksum routine - it the file contents are exactly the same, it'll always generate the same checksum. And MP3 is compressed right? Is there a way to uncompress those compressed sound so that I will really do unlock the wonderful sound of the audio?Why would you want to decompress a MP3 - decompression won't enhance the quality in any way !! You'll get to hear exactly the same frequencies as you hear in a compressed MP3.. When MP3 compresses a wav file - it cuts out a whole lot of frequencies which anyway wouldn't make an audible difference to the human ear. Andhow much it cuts out, depends on the encoding rate you choose... around 320kbps, it cuts out the least.. at 128kbps and less - it drops more.. When you decompress the MP3 - there's no way to get back these lost frequencies.. so your whole idea of "unlocking" the hidden sound will never work.

Regards, m^e <{POST_SNAPBACK}> Hmm... thanks for the reply... what about the compare thing? If it's the same file or not... i think i will be able to free some disk space if I delete those duplicated ones... I hope that everything would be automatic.

Moody 0 Report post Posted June 25, 2005 If you want to change the bitrate of a music file. This is a good program dbPowerAMP.You can change bitrate with this program, from WAV, MP3, WMA and some other files, in many different ways. I use it to put more music on my MP3-player.

You shouldn't go below 128 kbps though. Regarding the duplicate file issue, you should just go through your files and delete the dupes and tidy like if it was tidying your room.

Jeigh1405241495 0 Report post Posted June 27, 2005 If you go from a HIGHER bitrate to a LOWER bitrate, you WILL lose some quality. However, going from a LOWER bitrate to a HIGHER bitrate will not change the quality of the music. If you think about what you are doing it makes some sense.Going from 256k to 128k, you don't have the ability to retain that extra 128k of data. However if you have 128k of data, and go to 256k, you can have ALL of the 128k and still have leftover room. This will simply be unaffected data however since you've already disacrded everything above the original 128k. This is why if you take your MP3's and decompress them into a larger file format, you'll just have big file sizes eating up hard drive space but no extra sound quality.As far as those comparison programs go, it WUOLD help you save sopme room, but they likely couldn't be perfect at finding duplicates or even guarantee not to delete files that ARN'T duplicates...especially if u get a freeware version.

Moody 0 Report post Posted June 27, 2005 Of course you lose quality, but when you just wanna hear some music you can compress it to 128kb, it's enought for me. On my computer i leave it as high as possible, but for MP3 players or Ipods, it can by usefull to compress them. Share this post Link to post Share on other sites
Jeigh1405241495 0 Report post Posted June 27, 2005 YEa I usually have 256kish on my computer (as above that I don't really notice the dif personally...probably due to *BLEEP* speakers) but on my mp3 player I usually try to stick to 128kish, lets you have more songs without a noticeable quality drop.

YudzzY 0 Report post Posted September 5, 2005 use dbPowerAmp.. it will make the mp3 to the quality you like, like 128 or something.. but that wunt be 100% efficient, but there is the difference! check it out ;-) Share this post Link to post Share on other sites

g22coates 0 Report post Posted September 7, 2005 DbPowerAmp is a very good solution for compressing / uncompressing your media. You could also go and get a program called SoundForge. It also does many things like that. Last time I check it costs money so I don't know if that's your best option. When you were talking about many file names for one file. Personally I suggest just running a Windows search for something they all have in common. Then I would find the file you want and delete the rest of the files. Hope this helped you some:) Share this post Link to post Share on other sites
iGuest 3 Report post Posted July 23, 2008 Audio Books Mp3 Questions I have downloaded several Audio Books in Mp3 format, usually as 3-5 minute files, but a few of them are one long track of 15 hours. Is there any way to put breaks or pauses so that my player sees sees them as a series if tracks 3-5 min.S long -reply by Murky Share this post Link to post Share on other sites
Amaralin 0 Report post Posted August 16, 2008 Yeah... lowering the file size will definitely lower the quality. I usually don't like compressing my mp3 files because there almost always is a noticeable decrease in quality but I agree with g22. Try dBpoweramp Music Converter 13.
