I am thinking of getting ride of my all CDs because they take too much space and transfer all conten to a hard disk.
wave is the loss-less format, but it has no compression. I am looking for a lossless audio format with best compression ratio. I do not want mp3 because I want to be able to re-produce CDs in future if there is a need.
with lossless format, I can reproduce any format I want, be mp3 or wma.
Guess it comes down to support for playback of your tunes. If your just going to be playing back at home then no probs but if you want to transfer to a portable device then you'll have to make sure that device supports the format you choose. Personally I'd go for a more well known format myself so that you can have good support for playback and portable devices
Removing even redundant data means a loss of data. This cannot then be retrieved.
OK, it may not be immediately apparent that data has been removed but, it has. If the files are further manipulated by, say, converting to another format (lossy or lossless) then the lack of the previously redundant data may be important and prevent the conversion taking place.
:-) Fair enough, and I do agree with you, using lossy compression is not good.
Using say a JPEG (lossy) format to store an image is not good news, as any expansion, further manipulation and save will result in further loss of data. But if you use TIFF or PNG both of which are Lossless compressed formats then the data is always restored to it's orignal state when you expand before you begin manipulation.
Try saving any image file using, JPG, TIFF, PNG, and then BMP. You will find that the BMP file is huge compared to the other files, as BMP is truly uncompressed. And JPG is probably the smallest, as it's actual losing data and then compressing, when it compresses.
